Filtration treatment systems, also called “whole house water softeners,” are pretty similar to the smaller water filter you might have installed on the end of your kitchen faucet. Whole house filtration systems are available in a variety of styles, all designed to purify water through a different process:
Alkaline/Water Ionizer-
Using a process known as electrolysis, water is passed over electrically-charged plates and separated into two streams — one alkaline, the other acidic. The acids and alkalis are then filtered from the water, which becomes much cleaner as a result. Ionizing treatment systems are aimed at situations where hard water is the primary issue.
Activated Carbon-
Also known as a carbon filter, this type of filtration method works by using carbon sheets to attract and absorb larger particles like silt and sediment from your water. The result is water that tastes much better than you can get through other means, because it reduces the amount of chlorine and other contaminants that can give water a bad taste.
UV Filtering-
One of the newer technologies available, ultraviolet filtering is aimed specifically at eliminating viruses and bacteria that can be dangerous to your health, all without the need for additional chemicals. Because of their singular use, most homeowners will never need to install a UV whole house water filter.
Reverse Osmosis-
This type of filter is very popular mainly because it has the ability to remove all sorts of contaminants that can be a health hazard, as well as making sure the end result is clear and odor free. Basically, reverse osmosis works by forcing water through a semipermeable membrane that captures the contaminants and flushes them out using a pressurized system.
Infrared Filtering-
Like alkaline treatment systems, infrared filter systems are aimed at eliminating hard water symptoms. Using heat and light to negatively charge water, it reduces mineral buildup and gives the water a softer feel.
