Arsenic reduction cartridge

Arsenic can occur naturally in some parts of the UK. Although the water companies work to strict limits, some people prefer to adopt a "belt and braces" approach by fitting their own Arsenic reduction cartridge. These cartridges will need changing every 3 to 6 months dependent on the amount of water used and the water chemistry. Please note, the flow through this filter is relatively low (4 to 6 litres per minute) which means it is best fitted in a filter housing that feeds a separate sink top drinking faucet. Cartridge size, 2 1/2 inch by 9 3/4 inch.
