Finerfilters Whole House Water Filter System

Our Finerfilters whole house water filter system provides your entire home with cleaner, safer, and better-tasting water. It connects directly to your property’s incoming mains supply and removes sediment, chlorine, heavy metals, and other unwanted contaminants from every tap in the house.

The range includes double and triple-stage options in 10" or 20" jumbo housings for different property sizes.

Each system comes complete with sediment and carbon filtration, with triple models adding a GAC/KDF stage for extra protection against heavy metals and bacterial growth.

If you're aiming to improve your drinking water or protect appliances from limescale and impurities, this whole house setup is a proven solution that is available to buy today.

High Capacity Filtration for Any Size Home

Our jumbo housing systems are built for enduring filtration with a low pressure drop, even across multi-outlet properties.

The 10" double and triple units are ideal for one to three-bedroom homes. The 20" systems suit larger homes with two or more bathrooms or anyone looking to maintain stronger flow rates.

All systems feature sediment and carbon block filters to remove dirt, chlorine, VOCs, pesticides, and other organic compounds. Our triple-stage 20" system adds a GAC/KDF filter to target lead, arsenic, cadmium, and scale, with bacteriostatic protection built in.

Installation is simple and all housings are fitted with brass 1" ports and pressure release valves.

We recommend placing the unit as close to your incoming cold mains as possible so the entire household benefits from cleaner water at every outlet.

Finerfilters Jumbo Spun Polypropylene Sediment Filter (All Systems)

Due to the ruggedness and strength of this PP sediment water filter, it is perfect for use with prefiltering prior to various water filter systems. In this application, the depth melt-blown polypropylene is perfect for capturing particles that are 5 microns in size or above. A pre-filter is strongly recommended in any high-volume filtering application to protect the secondary/third filter from prematurely clogging with sediment which then doesn’t allow the cartridge’s full capacity to be used.

Its large diameter of 4.5" allows for more effective filtering of sediment, rust, dirt, and particles from your water than a standard (2.5") size filter.

Sizes: 10" Jumbo (10" x 4.5") / 20" Jumbo (20" x 4.5")

Capacity: Subjective to incoming water quality and sediment levels. We recommend checking pressure drop/flow rates after 3 months for optimal performance. A decrease in pressure or flow indicates that the filter has expired.

Finerfilters Jumbo GAC/KDF Water Filter (Triple Housing Systems Only)

This filter would primarily be used in an application where the aim is to remove chlorine, heavy metals, and VOCs from the water. The activated coconut carbon inside the filter is super absorbent and is designed to remove chlorine odour and taste from the water. KDF water filter media extends the life of granular activated carbon (GAC) while protecting the carbon bed against fouling by bacterial growth. An ideal filter in a whole house system.

This filter has bacteriostatic properties in addition to effectively removing chlorine, lead, arsenic, cadmium, and other contaminants that may be present in the water.

Sizes: 10" Jumbo (10" x 4.5") / 20" Jumbo (20" x 4.5")

Capacity:
10" Jumbo: 18,492 US Gallons / 70,000 Litres / 6 Months
20" Jumbo: 36,984 US Gallons / 140,000 Litres / 6 Months

Cartridge life span: 6 - 9 months, depending on the application and incoming water quality. Adding a pre-filter before this cartridge, such as a sediment filter will increase the lifespan.

Finerfilters Jumbo Carbon Block Water Filter (All Systems)

Reduces levels of Chlorine, Organic Compounds and Volatile Organic Compounds (VOCs). 5 Micron-rated particulate filtration also removes levels of rust, dirt, sand and sediment particles for greater water clarity.

Sizes: 10" Jumbo (10" x 4.5") / 20" Jumbo (20" x 4.5")
