The Watts EZFITPRO-400 Small Whole House System is ideal for small houses and flats up where average flow rates are 10-15 LPM and a maximum of 25 LPM.

The system is small and compact and ideal for fitting in cupboards and under kitchen sinks and uses 15mm push fittings for the inlet and outlet. This means your 15 mm copper or plastic pipe can simply be pushed into the unit and released with ease. This saves time and money on plumbing parts.

The Watts EZFITPRO-400 Small Whole House Systems reduces Chlorine, Fluoride, Arsenic,, Selenium, Sediment, Volatile Organic Compounds (VOCs), as well as any unpleasant tastes and odours from water. It is the perfect solution for an easy installation as it can be fitted in less than 15 minutes.

Filter 1: The Watts 5 Micron Coconut Carbon Block - changed every 3-6 months

Top-of-the-line NSF certified coconut shell carbon block filter cartridge for chlorine, taste, odour and sediment reduction. Media wrap between centre tube and carbon block to reduce carbon fines. Made from 100% Natural Coconut Shell Carbon. Up to 99% chlorine reduction. FDA grade components & materials.

Filter 2: The Activated Alumina Fluoride Filter - changed every 6-12 months

This main purpose of this filter is for fluoride removal, but it also reduces/removes arsenic and selenium from your water. The cartridge uses fine white granular media designed to reduce fluoride levels known as Activated Alumina. Activated Alumina is safe and non toxic, non-corrosive and not prone to oxidation and has been widely used and approved within the water filtration industry for many years. It is a recognised treatment media by the WQA (Water Quality Association) and British Water. Activated Alumina is currently one of the most effective method of extracting fluoride from water and is produced by a careful controlled calcination of alumina trihydrate.

This cartridge is perfect for those who are concerned about their levels of fluoride intake and want to reduce this from tap water. Unfortunately we cannot say precisely what percentage is removed from your water as the removal efficiency will depend on temperature, pH, water quality, flow rate, and concentration of suspended solids. However, the cartridge has an absorption capacity of 10 mg fluoride/g or 500mg/l so under optimal conditions may be fully effective at removing all the fluoride compounds. We would recommend the cartridge should be changed every 6-12 months (or 5000 gallons) whichever comes first.
