Point-of-use filters are designed to filter one specific source, such as the kitchen or bathroom sink, an ice maker or a shower head. Sink filters can rest on the counter with a tube to the faucet, or can be installed under the sink with a dedicated faucet.
Pre-Filters: Roughing filters, sock filters, cartridge filters are often used as pre-filters and are placed at the point where the water enters the building, or just before the fine filter used at the point of use. Other point-of-use systems that are more precise include:
These systems are generally installed in the well house or pump house, in the garage or basement, or in an adjoining shed or out building. The closer the filtration system is to the point of use, the less opportunity there is for any bacteria to build up in the pipes between the two points. If the water does have to travel a long distance from the well to the house, sometimes it is comforting to install a point-of-use filter on the sink as an added polish to the already clean water. In most cases, however, this is not necessary and is sometimes redundant.
For large communities, treating the water at the well may remove the worst concerns, such as hardness or iron or particularly bacteria, usually well water for communities does nothing more than chlorination. For this reason is often better for each residence to install an individual treatment system to remove the rest of the contaminants that the community system did not deal with. Even if the water is clean enough, at least removing the chlorine is a good idea. One other issue in large communities is that no one can agree as to which system to install, so often the homeowners are left to their own devices; some choose to live with the bad water, while others install various systems to treat some or most, but usually never all, of the water problems. Our oxygen system will solve them all.
