Water Filter: How Effective Are They?

Filtered water.

A home water filter is an effective way to rid your water of impurities, but a water filtration system does not remove bacteria. Most water municipalities use chlorine to purify the water. A water filter strips out the chlorine and parasites such as cryptosporidium and giardia that are chlorine resistant.

Home Water Filter Types

The basic home water filter systems available are under the sink devices, faucet water filter, built-in refrigerator filters for the water dispenser, and drinking pitchers with filters. An under the sink water filter is attached with a screw on plumbing connection so you don’t need a professional to install it.

Changing the Water Filter

Electronic indictors on the systems let you know when it’s time to change the filter. Filters do need changing because they lose their effectiveness over time.

How Does the Water Filter Work?

A water filter improves the taste of water by removing harmful substances. The filter traps small particles 0.5 microns or larger while allowing the healthful minerals and the water to flow through.

The most common kind of home water filter is charcoal. A filter cartridge holds charcoal granules. When the water passes over the charcoal granules it traps large contaminates stopping them from traveling through with the water. Tiny particles can get through a charcoal filter.

A multi-system water system uses a solid block carbon material from the husk of a coconut along with a chemical process. This system consists of positive and negative charges which act like magnets to attract the impurities in the water by breaking them away from the water and the carbon removes dirt and rust.

What Can a Water Filter Remove?

A water filter can remove harmful contaminants such as hydrogen sulfide, radon, chlorine, pesticides, volatile organic compounds, benzene, and lead. A water filter leaves the healthy minerals in the water that are the beneficial component in water.
