Water filters are designed to purify your drinking water, to remove any chemical or mineral contaminants that are present. There are two main types commonly in use these days - there are the filter jugs that you pour water into the top and the water goes through a filter cartridge (which can take about two minutes for 2 litres to be filtered) the advantage to this system is it is quite cheap.


The alternative is to have a water filtration system plumbed in under your sink so that the water is constantly filtered in line. The cartridges for the filter jugs are designed to be replaced on average once a month, depending on the quality of your water supply.  These free standing units have proved to be very popular and you will see them and the filter cartridges on sale in most supermarkets.


Either system will give you water that will be fresher tasting although neither system can remove salt from water. They will however remove aluminium, chlorine and fluoride, three of the most common and overall undesirable chemicals from your drinking water. It is a fact that not all drinking water supplies are 100% healthy so it is a wise precaution to take.


Water filters are installed in many peoples homes and countless work and office environments. They produce water that is visibly clearer and better tasting and they remove unpleasant chemical odours as well as any particles that were present in the water before filtering. Over the years the deign of water filters has improved and they are now quite sleek and attractive available in many colours to match the style of your kitchen. Also the flow rate has improved and they are no longer as heavy or bulky which is a good thing, they used to be far more cumbersome than they are now.


The majority of water filter systems use activated carbon and ceramic particles to actively screen out most contaminants from drinking water. The other types in common use are reverse osmosis which is generally regarded as the most comprehensive water filtering available and then there is ultraviolet sterilisation which is great for filtering/killing off any microbes and bacteria that may be present in the water but does not stop chemicals or metals that are often present in drinking water.


The best types of filters use a combination of filtering methods that will remove both microbial and chemical contaminants, although if you want the ultimate in water purifying, the most effective method is undoubtably condenser, there are sharply confilcting opinions in the scientific community regarding the safety of drinking condensed water which has been turned to steam then re-condensed on a cold plate. Certainly this kind of treatment is the most effective as it will even turn sea water into drinking water as well as leave behind any chemical pollutants and microbes and bacteria would be unable to survive this treatment.


Because this kind of water would contain absolutely no minerals whatsoever, there is a belief that drinking it would actually cause minerals to be removed from the body, but they would be chemically isolated minerals that your body doesn't need anyway. There are a number of commercially available water condensing systems available that you can have installed in your kitchen and they represent the ultimate in modern water purification
