Atlas Filtri Whole House PFAS DUO Kit Inc. 2 PFAS Cartridges 54LPM MARIC Valve

Dual Stage Whole House PFAS Reduction System (Atlas Filtri)

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

This high flow PFAS filtration system is designed for whole-home protection using dual PFAS ARMOR cartridges housed in a commercial-grade Atlas Filtri DP DUO 20” BIG system. It is intended for homes wanting broad water quality improvement with specific focus on reducing PFAS compounds such as PFOA and PFOS.

What’s Included

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

• 2 x Atlas Filtri PFAS ARMOR Cartridge 20” BIG

• Maric Valve 28LPM

• Reinforced polypropylene housing system

How It Works (Simple Explanation)

This system uses two large-capacity PFAS reduction cartridges working together to provide high flow whole-house filtration.

Stage 1 – PFAS ARMOR Carbon Block Cartridge

The first cartridge begins the reduction of PFAS compounds including PFOA and PFOS while also reducing chlorine, chemical taste, and odour.

The carbon block media is designed for high contact time and fine filtration performance, helping improve overall water quality before it reaches your home.

Stage 2 – Secondary PFAS ARMOR Cartridge

The second cartridge provides additional contact time and filtration depth, improving PFAS reduction performance while also polishing the water further.

Using two cartridges in series helps improve overall contaminant reduction capacity and supports higher whole-house flow rates compared to a single cartridge setup.

What Are PFAS?

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

They have historically been used in:

• firefighting foams,

• industrial manufacturing,

• stain-resistant products,

• non-stick coatings,

• and water-resistant materials.

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

Performance

• Rated flow: 54 LPM system capacity

• Maric valve regulated flow: 28 LPM

• Cartridge lifespan: approx. 113,400 litres per cartridge set

• Designed for whole-house mains water applications

Certification & Filtration Standard

The PFAS ARMOR cartridges:

• reduce PFOA + PFOS,

• reduce chlorine, taste, odour, and chemicals,

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

Why Use a Whole House PFAS System

Standard whole-house carbon filtration may improve taste and chlorine levels, but it is not always specifically tested for PFAS reduction.

This system is designed specifically for PFAS management throughout the entire home, helping reduce exposure from:

• drinking water,

• cooking,

• showering,

• and household water use.

This can be particularly important in areas affected by:

• historical firefighting foam contamination,

• industrial runoff,

• or known PFAS advisories.

Running Costs (Realistic Expectations)

PFAS filtration systems generally have higher operating costs due to the specialised carbon media required.

Typical cartridge replacement occurs every:

• 6 to 12 months,

• depending on water quality,

• PFAS concentration,

• chlorine exposure,

• and household water consumption.

Actual cartridge lifespan can vary significantly based on:

• incoming contamination levels,

• flow rate,

• and overall water usage.

Technical Specifications

• Housing type: DP DUO 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

• Whole-house chemical filtration

• High flow residential systems

• Homes in PFAS-affected regions

Important Notes

PFAS reduction performance depends on:

• contaminant concentration,

• flow rate,

• maintenance,

• and cartridge replacement intervals.

No whole-house carbon system guarantees complete PFAS removal under all conditions. Reverse osmosis systems generally provide the highest level of PFAS reduction for drinking water applications, particularly for short-chain PFAS compounds.

The Bottom Line

This is a serious whole-house filtration system built specifically for PFAS reduction, rather than a standard chlorine filter marketed for general water improvement.

With dual PFAS-specific cartridges, commercial-grade BIG housings, and high-flow capability, it is well suited to homes wanting broader protection against emerging contaminants while still maintaining practical whole-house flow rates.

For households concerned about PFAS exposure in mains water, this system represents a substantial step up from standard whole-house carbon filtration.
