Will a Water Filter System 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.

As some water filters remove biocides (substances that can control the growth of harmful organisms, such as chlorine), it is possible that bacteria will re-grow unless the filtered water is stored in a sterile container in a cool, dark place.

Some water filters may also allow bacteria to multiply to great levels on the filter pads if they are not maintained regularly.

In most circumstances domestic household water filters or ultra violet treatment systems will not make water safe in relation to amoeba unless you also disinfect with chlorine.
