At first, it may seem that whole house water filters would be extremely expensive when compared to other filter options, but they are actually a very cost-effective option for water filtration. The price range of these water filters is large, starting at two hundred dollars and costing as much as one thousand dollars. The price of the filters is dependent upon their size, material and life span. This may seem like an extremely high price, but when compared with other filter options, it is actually very cost effective because of the amount of filtering that it provides.
Whole house water filters purify water in the same fashion that other filters, such as countertop or under sink filters, do. The difference is that it requires only one filter, which is attached to the main water source, instead of needing multiple water filters to be attached to different devices. As with the other filters, whole house water filters purify tap water by forcing it through several different stages of filtration. One of the stages is carbon filtration. Carbon is a effective method of filtering water because it is porous and has the ability to remove small and large impurities. Carbon is essential in removing volatile organic carbon compounds, which in some cases can cause serious damage to the liver, kidney or central nervous system. Carbon also removes dangerous substances such as pesticides, industrial solvents and insecticides.
Another essential step of the filtration process involves a process such as ionization or micron filtration. This step removes hundreds of contaminants found in tap water, and transforms the water to great tasting, healthy drinking water. As mentioned earlier, the main advantage of whole house water filters are that they provide filtered water throughout the house with the use of only one filter.
Another advantage of whole house water filters is the long life span that they offer. Many of these filters last between fifty and one hundred thousand gallons of water. For many, the main disadvantage of whole house filters is the higher than average price. Although these filters are very cost effective, they do require a large investment up front. Whole house water filters can also require a significant amount work to install.
