Water Filters

Water filters generally come in two forms. Portable ion exchange water filters, and reverse osmosis water filters. Both are used for "point of use" drinking water, that is, to filter out harmful or unwanted particles before the water is used for human consumption. Reverse Osmosis works by forcing the water through a semi-permeable membrane, that stops certain particles from passing through.

Portable water filters work using a cartridge containing activated carbon and ion exchange resin. The carbon absorbs and helps reduce the levels of chlorine and chlorine compounds, as well as pesticides, colour and other organic substances. This improves taste and appearance. The ion exchange resin works to reduce temporary hardness.

Electromagnetic water conditioners are a relatively new invention. The idea is that by passing water through a magnetic field, the calcium and magnesium ion's are altered in such a way that they loose their ability to cause scale.

This has a number of benefits, although the water is not technically soft, it has the useful properties of soft water, that is, it won't cause lime scale in your pipes thus increasing heating efficiency and lengthening the lifespan of any clothes washed in the conditioned water.

Calcium is an important dietary element, so the fact that conditioned water still retains its calcium content is an added benefit. While some people are sceptical this method actually works, a scientific analysis by the University of Bath concludes that they do work.
