Choosing the best whole home water filter system for mains water is not as simple as picking the biggest filter, the most expensive cabinet or the system with the loudest online ads.

A proper whole home mains water filter should be selected around the way your home actually uses water. It needs to suit your incoming water line, household flow rate, pressure, number of bathrooms, installation location, service access, cartridge replacement cost and the level of filtration you actually need.

For Brisbane, Gold Coast and South East Queensland homes on treated mains water, the best whole home filtration system is usually a Puretec system matched to the property.

For JR Gas & Water, the strongest whole home mains water filter picks for 2026 are:

Best for hardness and scale-conscious homes: Puretec FilterWall F6
Best for full premium mains filtration: Puretec FilterWall F5
Best value covered whole home system: Puretec WH2-55 AMC
Best big-flow system: Puretec EM2-150
Best budget entry point: Puretec EM2-60
Best UV upgrade where required: Puretec Hybrid E13 AMC

JR Gas & Water supplies, installs and services whole home mains water filtration systems across Brisbane, Gold Coast, Logan, Ipswich, Redlands, Moreton Bay, Scenic Rim and nearby South East Queensland areas.

This guide compares the best whole home mains water filters by category, explains which system suits which home, and compares Puretec against other common filter brands without naming them directly.

Important Note on Competitor Comparisons

Australia’s water filtration market is full of polished Facebook ads, in-home demonstrations, wellness-style claims, online filter warehouses, cheap marketplace kits and retail house-brand filter systems.

Some of those products may suit the right home. Not every competing filter system is bad.

However, some companies in the water filtration industry are very protective of direct public comparisons, especially when another product is recommended above theirs. To keep this guide focused on useful buying advice rather than brand disputes, JR Gas & Water compares the main competitor types using anonymous labels.

That means this article compares Puretec against:

Brand A: the premium-looking whole-home water filter brand that seems to follow you around Facebook, Instagram and YouTube after you search for water filters once

Brand B: the in-home demonstration company that uses quick water tests, colour changes, hardness demos or handheld meters to make tap water look worse than it is

Brand C: the large online filter warehouse with hundreds of cartridges, housings, reverse osmosis systems and DIY filter kits

Brand D: the wellness-style water brand focused on alkaline water, mineral claims, lifestyle messaging and luxury drinking water language

Brand E: the cheap online marketplace filter kit that looks similar to a premium system but may not have the same fittings, compliance, housing quality or long-term cartridge availability

Brand F: the lower-cost retail or trade house-brand filter system that is easy to buy today but may not have the same specialist filtration support long term

These labels are not used to attack other businesses. They are used so homeowners can recognise the type of system being compared without turning the article into a brand-name argument.

The real question is not “which filter company has the best ad?”

The better question is:

Which whole home mains water filter is easy to service, easy to get cartridges for, suitable for Australian plumbing, correctly sized for household flow and still a smart choice in five years?

That is where Puretec stands out.

Quick Answer

The best whole home mains water filter system in Australia for 2026 depends on the home.

For most premium mains water homes, start with the Puretec FilterWall F6 or Puretec FilterWall F5.

For value-focused installs, start with the Puretec WH2-55 AMC.

For large homes needing bigger flow, start with the Puretec EM2-150.

2026 Whole Home Water Filter Awards

The 2026 JR Gas & Water Whole Home Water Filter Awards are based on practical mains water ownership, not sales hype.

A good whole home mains water filter should:

• Improve water throughout the property

• Suit the home’s flow rate

• Be practical to install

• Be easy to service

• Use cartridges that can be sourced long term

• Reduce common mains water taste, odour, sediment and chemical concerns

• Look appropriate for the home

• Be installed with proper valves, bypass and pressure planning

• Avoid fear-based sales tactics

• Avoid locking the homeowner into one supplier forever

How JR Gas & Water Ranked the Best Whole Home Mains Water Filters

Whole home mains water filtration is different from under-sink filtration, reverse osmosis, rainwater filtration and bore water treatment.

A whole home mains water filter is installed on the main incoming water line so it filters water before it reaches taps, showers, baths, toilets, laundry, hot water systems and appliances.

The ranking considers:

• Filtration performance

• Flow rate

• Mains water suitability

• Cartridge availability

• Serviceability

• Housing quality

• Presentation

• Weather protection

• Pressure suitability

• Bypass options

• Long-term ownership cost

• Ease of cartridge replacement

• Installation practicality

• Suitability for Brisbane and Gold Coast homes

• Whether the system can be serviced by normal plumbing channels

The best whole home filter is not automatically the largest system or the most expensive cabinet.

The best system is the one that suits the property.

Why Puretec Wins for Whole Home Mains Water

Puretec is the preferred brand in this ranking because it combines strong filtration products with practical plumbing serviceability.

That matters because a whole home filter is not a one-time purchase.

It needs:

• Correct installation

• Cartridge changes

• Pressure checks

• Flow checks

• Leak checks

• Bypass operation

• Ongoing servicing

• Replacement cartridges

• Long-term support

Many filter systems look good in an ad. Fewer systems are still easy to own five years later.

Puretec’s biggest advantages are:

• Reputable filtration brand

• Wide range of whole home mains water systems

• Options from economy to premium

• Replacement cartridges available through major plumbing retailers

• Strong trade supply support

• Good fit for professional plumbing installation

• Clear upgrade path across ranges

• Covered, cabinet and open-frame options

• Systems for standard homes, large homes and premium homes

• Better long-term serviceability than many proprietary filter packages

The best whole home filter is not just the one that looks impressive on install day.

It is the one that can be maintained properly year after year.

Best Overall Whole Home System for Hardness and Scale-Conscious Homes: Puretec FilterWall F6

The Puretec FilterWall F6 is JR Gas & Water’s best whole home mains water filter for homes concerned about hardness, scale build-up, chlorine, sediment, taste, odour and premium presentation.

This is the top pick for homeowners who want more than a basic exposed filter setup.

Why the Puretec F6 Ranks First

The F6 is the strongest whole home choice because it gives homeowners a premium enclosed system with broad mains water filtration and a better finish than standard exposed housings.

It suits customers who want:

• Whole home filtration

• Better water from every tap

• Reduced chlorine taste and smell

• Reduced sediment before water enters the home

• Filtration before showers, baths and appliances

• Help with scale-conscious water management

• A premium cabinet-style finish

• A cleaner exterior installation

• A system that looks intentional, not improvised

• Strong long-term serviceability through Puretec cartridges

The F6 is the best choice when the customer wants the “do it properly once” option.

Important Note on Hardness

Hardness is different from chlorine, sediment and taste.

Hardness relates mainly to minerals such as calcium and magnesium. These minerals can contribute to scale, spotting and build-up around fixtures and appliances.

A whole home filtration system should not be described as a true water softener unless the specific system and media are designed to soften water in that way.

The F6 is the best Puretec whole home option in this ranking for hardness and scale-conscious mains water homes, but customers with serious hardness complaints should still consider proper testing before assuming any filter will fully solve scale.

That is the honest way to sell it.

It is a premium mains water filtration system with scale-conscious benefits, not a magic fix for every water chemistry issue.

Who Should Choose the Puretec F6?

The Puretec F6 is best suited to:

• Premium homes

• New builds

• Renovations

• Families wanting better water throughout the property

• Homes with visible side access

• Customers wanting a neat architectural finish

• Homes concerned about chlorine smell in showers

• Homes wanting filtration before the hot water system

• Customers wanting the best Puretec mains water option

• Brisbane and Gold Coast homes on treated town water

• Customers who want serviceability without buying a social-media filter package

F6 vs Cheaper Whole Home Systems

The F6 is not the cheapest whole home filter.

That is not the point.

The F6 is for customers who care about:

• Presentation

• Build quality

• Premium finish

• Long-term ownership

• Stronger whole-home setup

• Better visual result

• Less exposed pipework and housings

• A more finished installation

A cheaper exposed housing system may still filter water, but it will not feel like the same level of home upgrade.

For premium homes, the installation finish matters.

JR Verdict

The Puretec F6 is the best overall whole home mains water filter in this 2026 ranking.

It is the top pick for hardness and scale-conscious homes, premium installs, families and customers who want the strongest long-term Puretec whole home system.

Best Full Filtration System: Puretec FilterWall F5

The Puretec FilterWall F5 is the best full filtration system for homeowners who want a premium FilterWall setup but do not necessarily need to step up to the F6.

This is the best “premium filtration first” option.

Why the Puretec F5 Ranks Highly

The F5 gives homeowners a premium enclosed whole home filtration setup that focuses on strong mains water treatment and presentation.

It is ideal for homes that want:

• Premium whole home filtration

• A clean FilterWall finish

• Reduced chlorine taste and odour

• Reduced sediment

• Reduced rust, sand and silt

• Better water throughout the property

• A better-looking installation than exposed housings

• Strong Puretec cartridge support

• A premium filtration result without stepping to the F6

If the F6 is the scale-conscious premium flagship, the F5 is the best full filtration choice for many homes that want a high-quality whole home filter without adding features they may not need.

Who Should Choose the Puretec F5?

The F5 may suit:

• Family homes

• Premium homes

• Homes with treated mains water

• Customers wanting full whole home filtration

• Customers who care about appearance

• Homes with chlorine taste or smell concerns

• Homes wanting better water for showers and appliances

• Renovations and new builds

• Customers comparing premium filter options but wanting better value than the F6

F5 vs F6

Choose the F5 if you want premium whole home filtration and a clean enclosed finish.

Choose the F6 if you want the strongest overall Puretec whole home choice and hardness/scale-conscious benefits are a priority.

JR Verdict

The Puretec F5 is the best full filtration system in this ranking.

It is one of the best choices for homeowners who want premium Puretec whole home filtration without necessarily needing the top F6 package.

Best Value Covered Whole Home System: Puretec WH2-55 AMC

The Puretec WH2-55 AMC is the best value covered whole home filter system in this ranking.

It is one of the strongest options for homeowners who want a proper whole home mains water filter with a neat protective cover, but do not want to spend FilterWall money.

Why the WH2-55 AMC Wins Best Value Covered System

The WH2-55 AMC is a smart middle ground.

It gives homeowners:

• Dual-stage whole house filtration

• 55 L/min flow rate

• A protective aluminium cover

• Better exterior presentation than exposed housings

• Mains water suitability

• Good filtration for sediment, chlorine, taste and odour

• Strong value compared with cabinet-style systems

• A practical install for many homes

• Puretec cartridge support

• A better-looking system than a basic open-frame setup

This is the best pick for customers who want filtration and presentation, but not the full premium FilterWall spend.

Who Should Choose the WH2-55 AMC?

The WH2-55 AMC may suit:

• Medium homes

• Families wanting whole home filtration

• Budget-aware owner-occupiers

• Customers wanting a covered exterior setup

• Homes where the filter is visible

• Customers upgrading from a basic exposed system

• Homes wanting strong everyday mains water filtration

• Customers comparing Puretec against social media whole-home packages

• Homeowners wanting the best balance of performance, price and presentation

WH2-55 AMC vs FilterWall F5

Choose WH2-55 AMC if value matters.

Choose F5 if finish and premium positioning matter more.

JR Verdict

The Puretec WH2-55 AMC is the best value covered whole home mains water filter.

It is the system many homeowners should compare before spending more on a premium cabinet or less on a basic exposed setup.

Best Big-Flow Whole Home System: Puretec EM2-150

The Puretec EM2-150 is the best big-flow whole home mains water filter in this ranking.

It is designed for homes that need stronger flow capacity than smaller systems.

Why the EM2-150 Wins Best Big Flow

The EM2-150 is built around flow.

It is the best option when the customer needs a larger-capacity whole home filter without moving into a cabinet-style premium system.

Its strengths include:

• 150 L/min flow rate

• Large 20-inch twin filter setup

• Stronger flow capacity than smaller 10-inch systems

• Good fit for larger homes

• Practical choice for multi-bathroom households

• Useful where multiple outlets may run at once

• Good option for homes with bigger incoming water demand

• Strong value for its capacity

• Puretec cartridge support

• Better fit than small filters for higher-flow properties

A whole home filter must not choke the house.

That is why flow matters.

Who Should Choose the EM2-150?

The EM2-150 may suit:

• Larger homes

• Multi-bathroom homes

• Homes with higher simultaneous water demand

• Homes where showers, laundry and taps may run at once

• Properties with larger incoming water lines

• Customers who want a high-flow open system

• Homes where pressure drop is a concern

• Customers wanting capacity over cabinet presentation

EM2-150 vs WH2-55 AMC

Choose EM2-150 when flow is the priority.

Choose WH2-55 AMC when presentation and value are the priority.

JR Verdict

The Puretec EM2-150 is the best big-flow whole home mains water filter in this ranking.

It is the right choice for larger homes that need stronger flow more than they need a premium cabinet finish.

Best Standard High-Flow System: Puretec EM2-100

The Puretec EM2-100 is the best standard high-flow open twin filter system.

It sits between the smaller economy systems and the larger EM2-150.

Why the EM2-100 Is a Strong Pick

The EM2-100 is a practical option because it gives many homes more flow capacity than entry-level systems without stepping all the way up to the highest-flow model.

Its strengths include:

• 100 L/min flow rate

• 20-inch twin filter setup

• Good whole-home capacity

• Practical open-frame installation

• Strong option for family homes

• Good value for larger mains water systems

• Useful where a 60 L/min unit may be too small

• Better flow profile than compact economy systems

Who Should Choose the EM2-100?

The EM2-100 may suit:

• Family homes

• Homes with two bathrooms

• Homes wanting stronger flow than 60 L/min

• Customers who do not need a cabinet

• Homes with moderate to higher water use

• Customers wanting a good balance between size and price

JR Verdict

The Puretec EM2-100 is the best standard high-flow system for family homes that need more than entry-level flow but do not require the EM2-150.

Best Economy Whole Home Filter: Puretec EM2-60

The Puretec EM2-60 is the best economy system in this ranking.

It is the entry point for homeowners who want whole home mains water filtration without paying for premium covers, cabinets or higher-flow systems.

Why the EM2-60 Wins Best Economy

The EM2-60 is the best budget entry because it gives homeowners a proper Puretec whole home filtration system at a lower price point.

Its strengths include:

• 60 L/min flow rate

• Twin filter setup

• Good entry-level whole home filtration

• Lower installed cost than premium options

• Puretec cartridge support

• Suitable for smaller to medium homes

• Better than many cheap marketplace kits

• Practical upgrade from no filtration

• Simple, serviceable design

This is the right system for customers who want better water throughout the home but are not ready for a covered or FilterWall system.

Who Should Choose the EM2-60?

The EM2-60 may suit:

• Smaller homes

• Budget-conscious homeowners

• Entry-level whole home filtration buyers

• Simple mains water installs

• Customers wanting Puretec without premium pricing

• Homes where the filter is not highly visible

• Customers who want performance over appearance

EM2-60 vs WH2-55 AMC

Choose EM2-60 when price matters most.

Choose WH2-55 AMC when presentation and protection matter.

JR Verdict

The Puretec EM2-60 is the best economy whole home mains water filter.

It is the best starting point for customers who want Puretec whole home filtration without premium presentation.

Best UV Upgrade: Puretec Hybrid E13 AMC

The Puretec Hybrid E13 AMC is the best UV upgrade where UV treatment is genuinely required.

For normal treated mains water, UV is not always necessary. But for homes with tank water, mixed supply, rainwater supply, or specific microbiological concerns, UV may be worth considering.

Why Hybrid E13 AMC Is Included

This article is mainly about mains water systems.

However, many SEQ homes are not simple mains-only properties. Some acreage homes, granny flats and mixed supply properties use rainwater, tank water, pumps or mains/tank combinations.

That is where the Hybrid E13 AMC becomes relevant.

It offers:

• Whole home filtration

• UV treatment

• Enclosed cabinet-style presentation

• Stronger protection where microbiological concerns exist

• Better fit for tank or mixed water than a standard mains-only filter

• A more complete system where UV is justified

Who Should Choose Hybrid E13 AMC?

The Hybrid E13 AMC may suit:

• Homes using tank water internally

• Mixed mains and tank water properties

• Acreage homes

• Customers wanting UV treatment

• Homes with microbiological concerns

• Properties where lab testing suggests UV is useful

• Homes where the customer wants an enclosed UV filter system

Important Note on UV

UV should not be sold just because it sounds impressive.

UV is useful for microbiological risk, but it does not replace sediment filtration, carbon filtration, pressure planning or proper system design.

UV also usually needs power and correct pre-filtration to work properly.

JR Verdict

The Puretec Hybrid E13 AMC is the best UV upgrade where UV is needed.

For normal mains water, start with F6, F5, WH2-55 AMC or EM2 systems first.

Whole Home Mains Water Filter Rankings 2026

Puretec vs Other Whole Home Water Filter Brands

There are many whole home water filter companies in Australia. Some have good products, some have strong marketing, and some may suit the right property.

The issue is not that every other system is bad.

The issue is that many alternatives are weaker when you look at long-term serviceability, cartridge access, plumbing compatibility and how the system is sold.

Puretec vs Brand A: The One Always in Your Facebook Feed

Brand A is the polished whole home filter company many homeowners recognise from Facebook, Instagram, YouTube and retargeting ads.

You search for whole house water filters once, and suddenly this brand follows you everywhere.

The ads usually focus on:

• Family health

• Children

• Showers

• Hair and skin

• Chlorine

• “Clean water” messaging

• Lifestyle upgrades

• Premium whole-home packages

• Emotional before-and-after style content

This type of company is not automatically bad. The system may improve taste, odour and chlorine exposure.

The issue is that the buying process often feels more like a sales funnel than a plumbing-led recommendation.

Before choosing this style of system, ask:

• Are the cartridges easy to buy through major plumbing retailers?

• Can any licensed plumber service the system?

• Is the customer locked into one service provider?

• Are the filters proprietary?

• Is the annual cartridge cost clear?

• Is the flow rate suitable for the house?

• Is pressure loss clearly explained?

• Does the system include a bypass?

• Is the installation done by a licensed plumber?

• Are the claims backed by proper testing?

Puretec wins this comparison because it is built around long-term plumbing serviceability.

Puretec cartridges are easier to source, plumbers know the brand, and the systems fit better into normal plumbing maintenance.

Puretec vs Brand B: The In-Home Water Test Demonstration Company

Brand B is the company that uses in-home water demonstrations to sell filters.

This is the style of business where someone visits the home, takes a water sample, performs a quick visual test, and then uses the result to recommend a filtration system.

The demonstration may show:

• Colour changes

• Particles

• Hardness reactions

• TDS readings

• Electrolysis-style visuals

• Chlorine reactions

• “Before and after” water samples

These demonstrations can look convincing, but they are not the same as a proper water quality report.

A quick onsite hardness test does not prove the water is unsafe.

It does not prove PFAS is present.

It does not prove heavy metals are present.

It does not prove bacteria are present.

It does not prove the filter being sold is the correct solution.

Hardness testing can be useful, but it mainly relates to calcium and magnesium minerals. It does not properly test for every drinking water concern.

JR Gas & Water’s approach is different:

If the result matters, test it properly.

For normal Brisbane and Gold Coast mains water, many customers choose filtration for taste, odour, chlorine reduction, sediment reduction and better household water.

For tank water, bore water, acreage homes, suspected contamination or serious health-based claims, proper lab testing should come first.

Puretec wins because it can be selected as part of a plumbing-led solution, not a fear-led demonstration.

Puretec vs Brand C: The Big Online Filter Warehouse

Brand C is the large online filter store with hundreds of cartridges, housings, under-sink kits, reverse osmosis systems, UV systems, spare parts and DIY filter packages.

These businesses can be useful for experienced buyers.

The problem is that most homeowners do not know exactly what they need.

They may not know whether they need:

• Sediment filtration

• Carbon filtration

• Whole home filtration

• Scale protection

• UV treatment

• Reverse osmosis

• Mains filtration

• Tank water filtration

• Bore water treatment

• Pressure control

• A bypass

• Outdoor-rated housings

• Different cartridge sizes

Buying from a catalogue can lead to the wrong system being selected.

Puretec is stronger for JR Gas & Water customers because it fits naturally into a professional plumbing installation. The products are easier to specify, source, install and maintain through normal plumbing channels.

Puretec vs Brand D: The Wellness Water Brand

Brand D sells water filtration through wellness language.

It often focuses on:

• Alkaline water

• Mineralised water

• Luxury drinking water

• Clean living

• Body benefits

• Lifestyle claims

• Premium tapware

• High-end kitchen messaging

Some customers like these systems. Taste preference is real, and some products may be fine.

The concern is when wellness language distracts from practical filtration questions.

Ask:

• What does it actually reduce?

• Are the claims backed by testing?

• Are cartridges easy to buy?

• Can a plumber service it?

• Does it suit Australian mains pressure?

• Does it need power?

• Does it need a drain?

• Is it whole home or drinking water only?

• Is the customer paying for filtration performance or lifestyle branding?

Puretec wins because it keeps the focus on filtration, service access, cartridge availability and practical installation.

Puretec vs Brand E: The Cheap Marketplace Filter Kit

Brand E is the cheap online marketplace filter kit.

It may look similar to a premium filter system in photos, but the difference is often in:

• Housing quality

• Fittings

• Pressure rating

• UV resistance

• Cartridge quality

• Documentation

• Warranty support

• Serviceability

• Compliance

• Replacement cartridge access

A cheap whole home filter connected to mains pressure can become expensive if it leaks, cracks, restricts flow or becomes impossible to service.

Before buying a cheap kit, ask:

• Is it suitable for Australian mains pressure?

• Is it suitable outdoors?

• Are the fittings compliant?

• Are cartridges easy to buy later?

• Is it sized for the whole home?

• Is there local support?

• Will a licensed plumber install it?

• Is there a bypass?

• What happens if it fails?

Puretec wins because it is a proper filtration brand with stronger long-term support.

Puretec vs Brand F: The Retail or Trade House-Brand Filter

Brand F is the lower-cost house-brand filter sold through large retail or trade stores.

These systems can be convenient and may suit basic filtration jobs.

The concern is long-term consistency and specialist support.

House-brand ranges can change. Cartridges can change. The system may be fine today but less clear in five years.

Before choosing this style of system, ask:

• Will the cartridges still be available?

• Is the product range stable?

• Is it a specialist filtration brand?

• Is it the best system or just the easiest one to buy today?

• Is it sized for the whole home?

• Does it have the right flow rate?

• Can it be upgraded later?

• Does it have matching premium options?

Puretec is stronger because it is a specialist filtration brand with a broader range and stronger long-term pathway.

Why Onsite Hardness Demos Can Be Misleading

One of the biggest issues in water filtration is the use of quick onsite tests to make normal water look alarming.

A salesperson may test your water and tell you it is hard, dirty or contaminated.

But a quick onsite hardness test is not a full water quality report.

Hardness testing can tell part of the story, but it does not properly test for:

• PFAS

• Lead

• Bacteria

• Nitrate

• Fluoride

• Pesticides

• Heavy metals

• Chlorine by-products

• Viruses

• Bore water safety

• Tank water safety

It also does not prove that a specific filter package is required.

A hardness demo can be useful if the issue is scale. It is not useful as a scare tactic.

JR Gas & Water does not believe homeowners should be pressured into expensive filtration because of a dramatic test in a kitchen.

If the claim matters, test it properly.

Why Lab Testing Matters

For normal mains water, many homeowners are comfortable choosing a whole home filter based on taste, chlorine, odour, sediment, water feel and household preference.

For serious concerns, the better pathway is proper water testing.

Testing is especially important for:

• Tank water

• Bore water

• Acreage homes

• Mixed water supplies

• Homes with staining

• Homes with unusual smell

• Homes with illness concerns

• Homes with suspected contamination

• Customers making health-based decisions

A lab test can help identify actual water conditions rather than relying on a sales demonstration.

Whole Home Filter Size Guide

Choosing the right system size matters.

A filter that is too small may reduce flow, frustrate the household and make the system feel like a downgrade.

Why Flow Rate Matters

Whole home filters sit on the main water supply.

That means every shower, tap, bath, appliance and hot water system may draw through the filter.

If the system is undersized, the household may notice:

• Slower showers

• Reduced tap flow

• Pressure drop when multiple outlets run

• Poor performance during laundry use

• Complaints when bathrooms are used together

• Frustration after installation

This is why JR Gas & Water does not recommend choosing purely on price.

The system must suit the home’s real demand.

Best System by Home Type

Best for Premium Homes

Best pick: Puretec FilterWall F6

The F6 gives the strongest premium whole home outcome, especially where finish, scale-conscious performance and long-term ownership matter.

Best for Full Filtration Without F6 Spend

Best pick: Puretec FilterWall F5

The F5 is the best premium filtration-first option for homes wanting strong whole home treatment and a cleaner cabinet-style finish.

Best for Medium Family Homes

Best pick: Puretec WH2-55 AMC

The WH2-55 AMC gives a great balance of filtration, cover, flow and value.

Best for Large Homes

Best pick: Puretec EM2-150

The EM2-150 is the best option when big flow is the priority.

Best for Budget Installs

Best pick: Puretec EM2-60

The EM2-60 is the best entry point into Puretec whole home filtration.

Best for New Builds and Renovations

Best pick: Puretec FilterWall F6 or F5

New builds and renovations are the best time to install a premium, clean-looking filtration setup with proper valves, access and future servicing space.

Best for Visible Side Access

Best pick: Puretec FilterWall F6 or WH2-55 AMC

If the filter is visible, presentation matters. A covered or cabinet-style system will usually look better than exposed housings.

Whole Home Mains Water vs Kitchen Filter

A whole home filter is not the same as an under-sink kitchen filter.

A whole home system filters water before it reaches the home.

That means it can improve water for:

• Showers

• Baths

• Bathroom basins

• Laundry

• Kitchen taps

• Hot water system feed

• Appliances

• General household use

A kitchen filter only improves water at one tap.

A kitchen filter is good if the only priority is drinking and cooking water.

A whole home filter is better if the goal is improving the water experience across the whole property.

Many premium homes eventually choose both.

Whole Home Mains Water vs Reverse Osmosis

Reverse osmosis is best used for dedicated drinking water.

A whole home filter is best used for property-wide water improvement.

They are different tools.

A whole home filter helps with:

• Chlorine

• Sediment

• Taste and odour

• Whole-house water quality

• Showers

• Appliances

• General household use

Reverse osmosis helps with:

• Dedicated drinking water

• Fluoride reduction

• PFAS reduction

• Heavy metal reduction

• Dissolved impurity reduction

For many homes, the best premium setup is:

• Whole home mains water filter first

• Reverse osmosis at the kitchen if drinking water concerns are higher

What a Whole Home Filter Can and Cannot Do

A good whole home mains water filter can make a major difference, but it should be sold honestly.

A Whole Home Filter Can Help With

• Chlorine taste

• Chlorine smell

• Sediment

• Rust particles

• Sand and silt

• Microplastics depending on system

• Taste and odour

• Organic smells

• Better whole-home water experience

• Cleaner water before appliances

• Better shower and bath water

• Better kitchen and bathroom tap water

A Whole Home Filter May Not Fully Solve

• Serious bore water issues

• Tank water bacteria without UV

• High hardness without specific treatment

• Fluoride reduction at RO levels

• Dissolved salts

• Every PFAS concern without matching cartridge/system

• Every heavy metal issue without testing

• Plumbing corrosion caused by old pipework

• Pressure issues caused by undersized pipes

The right recommendation depends on the water source and goal.

Installation Quality Matters

A good filter installed badly can still cause problems.

A proper whole home installation should consider:

• Main water entry point

• Incoming pressure

• Flow rate

• Pipe size

• Isolation valves

• Bypass valves

• Pressure limiting valve requirements

• Mounting surface

• Weather exposure

• Service clearance

• Drainage

• Cartridge replacement space

• Future access

• Hot water system location

• Existing pipe material

• Whether the job is wall-mounted or freestanding

JR Gas & Water installs filtration systems as plumbers, not just filter salespeople.

That matters because the system is connected to the home’s plumbing.

Service and Cartridge Replacement

Whole home filtration is not set and forget.

Every system needs cartridge replacement.

Depending on the system, servicing may include:

• Sediment cartridge replacement

• Carbon cartridge replacement

• Scale media replacement where applicable

• O-ring checks

• Housing checks

• Bypass checks

• Pressure checks

• Flow checks

• Leak checks

• UV lamp replacement where UV is installed

• System flushing

• Cartridge disposal

Puretec’s advantage is that replacement cartridges are easier to source through major plumbing retailers and trade channels.

That makes ownership easier for customers and service easier for plumbers.

Common Buying Mistakes

Choosing Based on the Loudest Ad

The best filter is not necessarily the one you see most often online.

Advertising spend is not filtration performance.

Buying From a Fear-Based Water Demo

A quick hardness or visual test should not be used to scare a homeowner into buying a system.

Ask what was tested, what was not tested, and whether the result proves that specific system is required.

Buying the Cheapest Marketplace Kit

Cheap filters can become expensive if they leak, restrict flow, fail under pressure or use cartridges that are hard to source.

Ignoring Flow Rate

A whole home filter must be sized for the whole home.

Do not install a small filter on a large house and expect premium results.

Forgetting About Servicing

If cartridges are hard to access, expensive or proprietary, the system may become frustrating later.

Should I trust an onsite hardness test?

Be careful. A quick onsite hardness test can show hardness, but it does not prove water is unsafe and does not test for every contaminant. Serious concerns should be checked through proper testing.

Any filter can affect flow if it is undersized or installed poorly. Choosing the right model and flow rate is critical. Larger homes should compare higher-flow systems such as EM2-100 or EM2-150.

Usually not for normal treated mains water. UV is more relevant for tank water, bore water, mixed supply or specific microbiological concerns.
