Information on Water Filter Types For Your Home

A water filter removes impurities from water by means of a fine physical barrier such as charcoal, or other chemical or biological processes. Some areas have very poor water quality and filtration is necessary to rid it of harmful qualities. Other people just want to be sure their drinking water is pure. If you are thinking about using filtered water rather than tap, there are some things to consider as you make your choice. First, there are several types of water filters to choose from. Choices include Pitcher Filters, Faucet mounted filters, Under Sink filters, and Whole House filters. Your choice of water filters will depend on how much of your water you plan to filter and how much money you want to spend. While you can purchase bottled water in most any store, purifying the water yourself with a water filter system will save you money. One quote we saw for filtering your own water with a faucet filter was about 18 cents a gallon, compared to around a dollar for an 8 to 12 oz. bottle. We describe the basic types of filters, makers of these filters, price ranges, and where you can buy them in this article.

Filter Types

The cheapest way to filter your water is with a Pitcher Filter. These filters are great if you just want to keep a pitcher of filtered water in your refrigerator for drinking or cooking purposes. The pitchers come in several sizes. The filter is held in the top of the pitcher, and water is poured in to the top. It filters through to the container portion of the pitcher, leaving impurities in the filter.

Faucet-mounted filters are attached to the faucet of a single sink so that all the water from this faucet is filtered. Many models come with a diverter so that you aren't wearing out your filter by running water for dishes, washing hands, etc.

Under Sink Filters are mounted under a single sink and usually come with a separate tap for your filtered water. These filters are larger than the filters for the previous two types, and usually last longer.

Whole House Filters are installed at the water source of your house, so that every faucet serves filtered water. These are much more expensive, and are generally used if your water quality is very poor and you want to filter water for all purposes, not just drinking and cooking.

Who Makes Them, How Much Do They Cost and Other Details?

  • Pitcher Filter
    Pur Pitcher filters get the best rating from most of the review sites we checked, because their filter can remove more impurities than the other top models. Pur's 9-cup pitcher sells for around $30, with each filter costing about $9. The filters will purify up to 40 gallons of water--approximately 2 months worth. Brita is another well-known manufacturer of water filters, and they are best known for their pitcher style as well. Their pitcher costs between $15 and $50 depending on size. Filters run about $9 on up, and also last about as long as the Pur filters.
  • Faucet-Mounted Filters
    If you are considering a faucet filter, Pur also makes the Ultimate 3-Stage Horizontal filter, which costs about $40. Filters cost about $15 each, and will filter from 60 to 100 gallons of water before needing replacement. There is also a bypass feature to switch from filter to tap water for washing hands, dishes, etc. The Pur Plus undersink type of water filter sells for around $90, claims that it is easy to install, and the filter lasts for about 6 months. Brita also makes a faucet-mounted filter which sells for around $40.
