Whole House – Mains Water – PFAS Reduction

Single Stage Whole House PFAS Reduction System (Atlas Filtri)

A compact whole-house filtration system designed to reduce PFAS contaminants, chlorine, taste, odour, and chemical impurities from mains water supplies.

This system uses a single Atlas Filtri PFAS ARMOR cartridge housed in a commercial-grade 20” BIG housing, providing targeted PFAS reduction for homes wanting improved water quality with a simpler and more cost-effective setup than larger dual-cartridge systems.

What’s Included

• DP Mono Filter Housing 20” BIG 1.5” In/Out

• 1 x Atlas Filtri PFAS ARMOR Cartridge 20” BIG

• Maric Valve 28LPM

• Reinforced polypropylene housing system

How It Works (Simple Explanation)

This system uses a specialised PFAS reduction carbon block cartridge designed for whole-house mains water treatment.

Stage 1 – PFAS ARMOR Carbon Block Cartridge

The PFAS ARMOR cartridge is designed to reduce PFAS compounds including PFOA and PFOS while also reducing chlorine, taste, odour, sediment, and chemical contaminants from household water.

The 1 micron carbon-based filtration media provides extended contact time to improve contaminant reduction while still maintaining practical whole-house flow rates.

What Are PFAS?

PFAS (Per- and Polyfluoroalkyl Substances) are often referred to as “forever chemicals” because they break down extremely slowly in the environment.

They have historically been used in:

• firefighting foams,

• industrial manufacturing,

• stain-resistant coatings,

• non-stick cookware,

• and water-resistant products.

PFAS contamination has become a growing concern due to potential long-term environmental and health impacts.

Performance

• Maric valve regulated flow: 28 LPM

• Cartridge lifespan: approx. 113,400 litres

• Designed for whole-house mains water applications

• 1 micron carbon block filtration

Certification & Filtration Standard

The PFAS ARMOR cartridge:

• reduces PFOA + PFOS,

• reduces chlorine, taste, odour, and chemicals,

• and meets PFAS reduction criteria under NSF/ANSI 53-21 test protocols for PFAS reduction.

Atlas Filtri states PFAS reduction performance of up to 95% under tested conditions.

Why Choose a Single Cartridge PFAS System

This system offers a more compact and economical option compared to larger dual-cartridge or multi-stage PFAS systems.

Benefits include:

• lower upfront cost,

• simpler installation,

• reduced maintenance complexity,

• and practical whole-house protection for moderate household demand.

It can be suitable for:

• smaller homes,

• lower occupancy households,

• or homes wanting PFAS reduction without moving to a larger commercial-style system.

Running Costs (Realistic Expectations)

PFAS reduction cartridges generally have higher replacement costs due to the specialised filtration media used.

Typical replacement intervals are:

• approximately every 6 to 12 months,

• depending on water quality,

• PFAS concentration,

• chlorine exposure,

• and household water usage.

Actual cartridge life can vary significantly based on:

• incoming contamination levels,

• flow demand,

• and sediment loading.

Technical Specifications

• Housing type: DP Mono BIG

• Filter size: 20” BIG

• Inlet/Outlet: 1.5”

• Max pressure: 8.3 bar

• Operating temperature: 4°C to 45°C

• Housing material: Reinforced polypropylene

Best For

• Mains water homes

• PFAS reduction applications

• Reducing chlorine taste and smell

• Smaller whole-house systems

• Lower to moderate water demand homes

• Homes in PFAS-affected areas

Important Notes

PFAS reduction performance depends on:

• contaminant concentration,

• flow rate,

• cartridge condition,

• and maintenance intervals.

Single-cartridge systems generally provide lower total contact time and lower overall contaminant capacity than dual-cartridge or multi-stage PFAS systems. Reverse osmosis systems typically provide the highest level of PFAS reduction for dedicated drinking water applications.

The Bottom Line

This is a practical entry-level whole-house PFAS filtration system designed for homes wanting broader protection against PFAS and chemical contaminants without the cost and size of larger dual-stage systems.

Using a specialised PFAS-certified carbon block cartridge and commercial-grade BIG housing, it provides a solid balance between performance, flow rate, and simplicity for whole-home mains water filtration.
