Water filters, purifiers and water filtration systems convert ordinary tap water into perfectly safe drinking water. They remove impurities and contaminants by means of a fine physical barrier or a chemical process.

Health benefits of a water filter:

A water filter or water purifier is very beneficial for healthy living. Ordinary water contains numerous contaminants including bacteria, algae, viruses, fungi, minerals, and man-made chemical pollutants that cannot be seen with the naked eye. These contaminants not only cause the water to taste bad, but are also very harmful to your health.

A water filter kills all of these organisms and filters out the contaminants to make the water fit for drinking. Thus water filters save us from many dangerous bacterial and viral diseases that spread due to the contamination of water.

The working technique of water filters is based on sieving, ion exchanges and other processes. A water filter can eliminate particles much smaller than the holes through which the water passes.

Alkaline water ionizers provide alkaline water. The following are the health benefits of alkaline water:

Promotes optimal physical performance.

Protects DNA from oxidative damage.

Alleviates blood sugar levels in diabetic patients.

Betters liver function exams in hepatic disorders.

Betters gastro duodenal ulcers and prevents recurrences.

Betters allergic disorders such as asthma, urticaria, rhinites and atopic dermatitis.

Betters hypertension and hypotension.

Betters serum bilirubin levels in newborn babies.

Impressively suppressed the growth of cancer cells transplanted into mice, demonstrating their anti-cancer effects.

The following are acid water health benefits:

Electrolyzed oxidizing water inactivates Escherichia coli and Listeria on plastic kitchen cutting boards.

It reduces bacterial load of treated alfalfa sprouts between 91.1% and 99.8%.

It can reduce food borne pathogens.

It is a useful disinfectant for hospital infections.

Water filters and purifiers can be purchased at water filter stores and online. The Pur water filter and Brita water filter are the two well-known brands of water filters.
