The time when you can drink right off the faucet is coming soon and you no longer need to worry about the various associated health concerns that come with contaminants. Whole house water filters come in different types with different objectives so determine how these can best suit the needs of every family member. Find out more how to observe and verify available water.
What is the Right Filter?
Whole house water filters are categorized into two namely point-of-entry units and point-of-use units. Point-of-entry units treat water before it is distributed to different areas of the house while point-of-use units include faucet filters, under-the-sink attachments, filter pitchers and other countertop filters. It is possible for some models to use two or more filtration technologies. It is recommended that you look for filters certified to remove the present contaminants in your water. These will be labeled as meeting the NSF/ANSI standard 53.
The NSF certification program helps verify a number of manufacturing claims. Although it is not fully flawless, it at least provides you with some assurance regarding quality and functionality of the product. These products are shown to have been independently tested to prove their efficacy in reducing specific pollutant levels within given parameters and specified conditions. Meeting Standard 53 means that the whole house water filter is designed for both aesthetics and health.
On Activated Carbon Filter
An activated carbon filter meeting NSF Standard 53 filters out almost all pollutants that concerns a particular home. More complicated and complex ingredients will require more advanced filters. Activated carbon filter is positively charged and highly absorbent which attracts and traps different impurities. It is commonly used in countertop filters, under-the-sink units and faucet filters. Several materials and particles are controlled such as bad odor and taste including chlorine, heavy metals like mercury and copper, parasites like Giardia and Cryptospordium, disinfection by-products, pesticides, radon, VOCs like MTBE, TCE and dichlorobenzene.
Whole house water filters also include cation exchange softener which trades minerals having a strong positive charge with others with less charge to “soften" hard water. This is used in point-of-entry and whole-house units and effectively gets rid of calcium and magnesium. These minerals form deposits, barium and other dangerous ions in fixtures and plumbing.
Distillers work by boiling water then recondensing the purified steam. These are usually used in countertop and whole house point-of-entry units and may also be combined with a carbon filter. Distillers control heavy metals like copper, cadmium, chromium, mercury and lead. Other materials controlled include fluoride, sodium, selenium, arsenic and barium.
Reverse osmosis involves using a semi-permeable membrane to separate the impurities from the water. It is commonly used in under-the-sink units and may also be used with a carbon filter or UV disinfection unit. The process gets rid of parasites, heavy metals, pollutants, selenium, nitrate, nitrite, arsenic and perchlorate. Reverse osmosis however, poses disadvantages such as wasting water and removing important minerals from it. Ultraviolet disinfection involves the use of ultraviolet light to kill bacteria and other germs. It is used in under-the-sink units with a sediment screen or carbon filter to control parasites, bacteria and viruses.
Whole house water filters will last for the long term if you know how to maintain it properly. Read and follow the manufacturer's directions for use and maintenance. Change the cartridge as needed and have a professional look at the unit every now and then to check on build-up of contaminants and pollutants.
