We have all heard the term hard water. This is water with an unusual high calcium content in it. Calcium will affect how well your soaps perform and will also leave a heavy film in the tub or sink as it dries. Calcium is a mineral that a lot of groundwater flows through. This will also give the water a not so pleasing taste.
To filter hard water means to reduce the amount of calcium going through. These filters are available in a wide variety of applications. You can find water filters to attach directly to your faucet all the way up to the whole house filters that attach to the main water line coming into the house. With each type of filter option you have, be sure to study which offers the best efficiency for your application. Also you should get your tap water tested before purchasing any system to ensure you get one that will suit your needs and make us happy.
The expense of these filtration systems vary depending on the method of filtration used. A reverse osmosis system will be much more expensive than the basic cartridge filter found at Lowes or Home Depot. The cartridge filter however is much easier to maintain and is a basic inline filter whether it goes through a single filter station, double station or even a triple station before the water has completed the filter process. Filters will state on the packaging what minerals and particulates they can handle and to what degree.
