There are many different water household purifiers on the market and if the consumer is to find an effective, yet affordable product, he or she needs a little help. Here are four tips that should make buying a tap water purifier, easier for you. There are many different considerations, but these four things are the easiest to spot.
Is there a reverse osmosis step?
At one time, the only effective water household purifiers relied on reverse osmosis to remove impurities. The problem is that also removed minerals, which are good for our health and improve the taste.
Sub-micron filtration has replaced reverse osmosis, but some manufacturers still include the step, mainly to drive up the price. For example, a tap water purifier that fits under the kitchen sink, effectively removes chemicals contaminants like THMs and includes a reverse osmosis step costs nearly 0. You can get a system that does the same job with submicron filtration for less than 0.
Does the company have certifications from independent laboratories?
Although industry regulations do not require that manufacturers have their products tested by independent laboratories, the better companies do. When you go to buy a tap water purifier, look for certifications by NSF and/or UL, the National Sanitation Foundation and the Underwriter's Laboratory.
A claim that is certified by WQA is not really certified. WQA is a trade group and they do not require sufficient data to ensure accurate performance claims. In the past, water household purifiers have been recalled or completely removed from the market for leaching harmful materials. Independent lab analysis ensures the consumers safety.
Is the product sold in California?
The state of California has higher standards for excellence than other areas of the US. Because of this, some companies avoid doing business there. If you are ordering something on line and the fine print says, "Not available in CA, WI and IA", it means that the company does not want to try to qualify for the legal standards, applicable for a tap water purifier, in those states.
The best water household purifiers actually have a certificate from the California Department of Public Health. That means the company took additional steps to prove the safety and effectiveness of their products.
Does the price tag seem awfully low?
If a tap water purifier costs less than , there's something wrong with it. One or all of these things could be the problem:
Does not provide effective contaminant removal
The company is about to upgrade and trying to "sell off" their remaining inventory
The units are cheap, but the filters cost more and require frequent replacement
Product performance data will cover contaminant removal. You should be sure that the system reduces THMs. The cheap brands are mostly chlorine filters.
Check that the filter lifespan is 500 gallons or more. The cheap brands are only good for 100. You would have to replace it every 4-6 weeks.
The best water household purifiers cost between 0 and 5.
