MWF 20" x 4.5" Triple Whole House Water Filter with PFAS & Chlorine / Chloramine Removal Cartridge Pack
This cartridge pack is the perfect solution for any home Australia wide using an industry standard triple whole house water filter on city and town water supplies. These cartridges are purposely selected to work in conjunction with each other so you have the best quality water possible flowing into your home. Take a look below at what each cartridge will do to create the water we want. To start, the sediments are removed to protect the cartridges in positions 2 and 3. Then the carbon block cartridge starts to remove the chlorine, PFAS and other contaminants. Then in the third position, this is the specialty cartridge tidying up the water and ensuring all the nasty contaminants are removed before the water flows into your home.
This Cartridge Pack Includes:
- 1 x 5 micron polyspun sediment cartridge
- 1 x 5 micron carbon block cartridge
- 1 x Disruptor cartridge
Stage 1: Polyspun Sediment Cartridge

Sediment filtration is a vital part of any water filtration process. A sediment filtration cartridge does just that, it removes the sediments from the water source you are trying to filter. At times preparing the water quality for the next stage in the process so that cartridge can perform at its best and last for as long as possible.
Sediment Cartridges Remove
- Algae
- Dirt
- Particulate matter
- Rust
- Sand
- Sediment
- Silt
Please note: Do not rely on sediment cartridges to filter untreated or unknown water sources for human consumption.
Stage 2: Carbon Block Cartridge

Carbon block cartridges are one of the most effective and widely used technology in the point of use water treatment industry today. Solid carbon block cartridges, or simply carbon blocks, are used either as standalone treatment methods or in a system with other cartridge types.
Carbon is a very versatile and highly effective water treatment medium. It has immense surface area. Approximately half a kilogram of carbon contains a surface area of over 50 hectares (0.5 square kilometers). It is the best known treatment for organic chemicals, volatile organic chemicals, pesticides, herbicides, chlorine and its by-products. It is also an unchallenged taste-and-odor improver. When arranged in solid carbon or extruded carbon block format, it also provides very high quality particulate filtration, in some cases down into the submicron level.
Features and Benefits:
- Chlorine free hot water for washing food at the kitchen sink
- Softer hair & skin
- Stops poisonous chlorine gas in the shower
