What does a water filter filter out?
Herein, what do water filters not remove?
Tap water should always be carbon filtered before distillation, else the VOCs and chlorine will re-enter the distilled water or will be released into the air for you to breathe. Contaminants that people most frequently want removed that are not readily removed by carbon filtration are fluoride, nitrates, and sodium.
Just so, do water filters remove bacteria?
Only a reverse osmosis water filtration system will effectively remove harmful bacteria. The simplest way to remove harmful bacteria is to disinfect the water by chlorination or by ultraviolet radiation.
Study: Bacteria can grow in faucet water filters. Listen to today's Environment Report. Water filters that you attach to your faucet are known to be good for filtering out heavy metals like lead and disinfectants like chlorine. But they're not designed to filter out bacteria that can grow in the filter itself.
