A guide to water filters counter

Want the best under counter water filter? Of course, you do. Your family deserves. But, you must shop carefully to counter water filters, or you can spend more while getting less protection.

If you are treated in public water, virtually guaranteed the presence of certain contaminants. The most popular treatment, among public providers, is chemical disinfection to reduce the threat of waterborne diseases.

Scientists and environmentalists argue the risk-benefit ratio of chemical disinfection, but since it’s cheap and modern standard, continues to be used, regardless of the risks. The most commonly used chemical disinfectant is chlorine. Then, you need an under the counter water filter that reduces chlorine of at least 99%.

Chlorine consumption causes digestive problems and in children can produce anemia. But, the greatest risk is not from a chemist herself, but the by-products that are released when he meets with water dwelling bacteria and other life forms.

One of the byproducts is chloroform. Another is the BDE. Different disinfection by-products there at least 10 in all publicly treated water. The levels are measured and reported as total trihalomethanes or TTHMs.

Under the counter water filters should reduce THMs at least 99%, because consumption causes a wide range of diseases, including cancer of the rectum and bladder. The compounds become airborne during cooking, so for maximum protection, you should leave the filter in the “on” position when the water to cook with.

There are only two under counter water filters on the market to reduce THMs to at least 99%. One costs $ 680. The other costs $ $143,98, when purchased directly from the manufacturer. You are probably wondering what’s the difference.

The most expensive under counter water filter includes a passage by osmosis. The other includes filtration, a submicron carbon and ion exchange.

In order to remove the cysts, which are resistant to chemical disinfection and can be present in any publicly treated supply, you must reverse osmosis filtration or both submicron. Obviously, reverse osmosis cost more. What are the advantages of osmosis?

There are none. Counter water filters containing submicron filtration provides the same protection without removing the minerals that may be present in the data source. Reverse osmosis removes dissolved minerals.

Through the exchange of ions, the least expensive under counter water filter removes lead and other metal particles, their exchange of mineral ions, such as potassium. This step improves the taste and smell, while the balance of the mineral content and protects you from the dangers to health of the consumption of lead.

In case of contamination by MTBE, which is present in many local supplies, as a result of underground tanks leak, I actually want to buy the less expensive system. The more expensive only reduces the MTBE of 77%. The least expensive under counter water filters reduce contaminant content of 97%.

Is a chemical product hard to get out of the water, as it dissipates quickly. So, you can see how you could easily spend more for an under the counter water filter that actually no less. Don’t need osmosis.
