You might be familiar with charcoal filters from using the hand-held water filter pitchers that are used domestically. However, if your water has a bad or “funny” taste or you are concerned with contaminates, installing a charcoal water filter should solve these problems.
Charcoal water filter variety
There are three basic types when purchasing a charcoal water filter:
• Activated Silver Impregnated Charcoal-This should add bacteria killing ability to a charcoal water filter.
• Carbon Block-This is considered the best charcoal water filter, but is known to work more slowly than the other types of filters.
• Micron Rating-A micron rating of 1 (one) or below is recommended to accurately deny entry of harmful bacteria and contaminates.
How charcoal water filters work
The worst water contaminates are Cryptosporidium and Guardia. Charcoal absorbs impurities and contaminates as water passes through the charcoal water filter. A good water filter system should remove benzene, chlorine, pesticides, and radon.
Don’t expect a charcoal water filter to remove everything, as some minerals are essential in helping to maintain good health. If you live in an area known to have a lot of water contaminates, you might want to consider installing a secondary pre-filter. Charcoal water filters should be changed about every six months.
