The quality of our tap water is pretty poor, and in cities can be recycled as many as 20 times. The best way to improve its quality is with a plumbed-in filter. We sell a high quality four–stage carbon drinking water filter (including free cartridge and tap) for only £70, which removes chlorine, toxic chemicals, heavy metals, etc. We do specialized cartridges (which last a month) for fluoride, estrogen and other pcbs. Whole-house filters will remove chlorine which turns into pernicious chloroform gas in a hot shower or washing machine.
