Whole House - Mains Water - Chlorine, Sediment and Scale
3 Stage Whole House Chlorine and Scale Reduction System (Atlas Filtri)
Clean, better-tasting water for your entire home, with added protection against scale buildup.
This 3 stage filtration system is designed to remove sediment, reduce chlorine, and manage limescale, improving water quality throughout the house while also protecting your plumbing and appliances. It is a practical, high flow setup suited to mains water supplies, using proven Atlas Filtri components.
What’s Included
20” BIG 10 micron pleated sediment cartridge
20” BIG 5 micron carbon block cartridge
20” BIG ScaleArmour scale reduction cartridge
DP Trio moulded head and housing system
Pressure gauges to monitor filter condition
Protective cover
How It Works (Simple Explanation)
This system uses three stages of filtration, and each one has a job.
Stage 1 – 10 Micron Pleated Sediment Filter
This is your first line of defence. It removes fine particles such as dirt, rust, and organic debris like bark and leaves. This helps protect your plumbing, tapware, and appliances from wear and buildup.
Stage 2 – 5 Micron Carbon Block Filter
This stage reduces chlorine, improving the taste and smell of your water. It also provides a final level of fine filtration down to 5 microns, polishing the water before it enters your home.
Stage 3 – ScaleArmour Scale Reduction Cartridge
This stage is designed to manage limescale. It reduces scale formation by up to 86 percent, helping to prevent white staining, streaking on glass, and buildup inside pipes and appliances. This is especially useful in areas with harder water.
Performance
Rated flow 26.6 L/min
Estimated capacity 209,000 litres (90 percent chlorine reduction at 2 ppm)
Why Add Scale Reduction
Standard filtration improves water quality, but it does not address scale.
Scale can cause long term issues such as:
• White spotting on taps and shower screens
• Reduced efficiency in hot water systems
• Buildup inside pipes and appliances
By including a dedicated scale reduction stage, this system helps protect your entire home, not just improve water quality.
Running Costs (Realistic Expectations)
Cartridge replacement typically occurs every 6 to 12 months depending on water quality and maintenance.

Best For
Mains water homes
Reducing chlorine taste and smell
Managing scale and white staining
Protecting plumbing, appliances, and hot water systems
Whole house filtration setups
The Bottom Line
This system builds on a standard 3 stage setup by adding scale protection.
It is still a simple, reliable system, but with an extra layer of protection for your home. If you are dealing with hard water or want to reduce long term maintenance on appliances and fixtures, this is a strong step up from a standard chlorine removal system.
