Quality Water Filters 4 You Posting Page
Wednesday, June 12, 2013
At a minimum, safety and comfort are achieved with a drinking water filter and a shower filter. The drinking water filter is installed at the point of use – typically the kitchen faucet – and can take a variety of forms. Undersink filters of various kinds, including reverse osmosis filters for truly heavy-duty purification, are one possibility. Countertop filters with diverter valves that hook up to the faucet are another option.
In both cases, the goal is to provide clean, safe drinking water free of dangerous contaminants. However, though these filters are perfectly suited to cleaning cool or cold water for drinking and cooking purposes, they are poorly matched to the task of removing chlorine from shower water. The volume of water used in a shower is much higher, so chlorine removal requires different media in different quantities, and the heat of bathing water would destroy the innards of most drinking water filters outright.
Shower filters use catalyzing media to change chlorine, chemically and electrically, into chloride. Since chloride particles are larger, they cannot be absorbed through the skin like chlorine particles can. They also do not become airborne as easily, greatly lessening inhalation risks. Shower filters contain media that catalyze chlorine into chloride, and may perform some additional basic filtering, but which are generally not suitable for creating potable water of the quality needed for drinking and cooking.
Thus, since shower filters can't produce good drinking water, and drinking water filters are useless for removing chlorine from shower water, you probably need two water filters for your home if you live in an area with mild to moderately contaminated water.
If there is heavy overall contamination of your water supply, a third water filter – a whole-house filtration system that cleans all water that enters the home, regardless of its final destination – may also be needed. Some of these filters are suited to clearing out chemicals if you live in an industrial zone or near to a factory farm that fills the water with fertilizer and insecticide on a regular basis. Others can help “soften” hard water that has excessive minerals in it before the liquid is redirected to faucets, showerheads, and so on. Shower filters and drinking water filters are still likely to be needed at the point of use to create more refined, better-filtered water after the initial “bulk decontamination”. This goes to show, however, that in some cases no less than three water filter types may be needed to remove all contaminants from the water properly.
