Water purifiers – how to choose the best RO water purifiers
If you read a few words about water purifiers, it will be easier for you to buy an effective water purifier. There are many RO water purifiers on the market. Some of them are designed to “fit any décor”. But the most important thing is what the system does, not how it looks on the counter.
Water treatment is a complex process. But you don’t have to worry about that. You just need to know where to look for information. You don’t have to learn how to build your own water treatment system. It won’t work anyway.
The production of water purifiers in Japan is largely unregulated. As a result, some products have little or no effect. Even if they are advertised as water purifiers, don’t believe the ads.
Now, fortunately, in some states water purifier manufacturers are required to provide certificates and data on the performance of their products along with their “sales figures”. These are independent evaluations of the performance of water purifiers.
So, no matter where you live, if a water purifier manufacturer is operating in a state that requires it, they must have product performance information. Most reputable companies have product performance data because they sell their products nationwide (and, thanks to the Internet, worldwide). Here are the following
The water purifier must block chlorine. The amount is indicated in the data sheet. Well-known brands, such as those sold in department stores, block only 75% of harmful chemicals. Good water purifiers exclude 99.99% and are certified by the Underwriter’s Laboratory.
A good water purifier should exclude lead, as lead is toxic at all levels and is found in many public drinking waters. The technology that enables water purifiers to exclude lead also excludes copper. So if you have a problem with excessive copper contamination in your fixtures, the right water purifier for your home will block lead and copper.
VOCs and THMs are cancer-causing chemicals found in most public water supplies; THMs are byproducts of chlorine disinfection. Surprisingly, many water purifiers block chlorine, but most do not block the byproducts. It’s absurd, but true.
MTBE has been found in many parts of the country in public water supplies. It is a gasoline additive that enters groundwater through leaks from underground tanks and from gas stations. There are very few water purifiers that block MTBE.
The term “cyst” refers to the early stages of parasite growth. Cryptosporidium cysts can cause illness and death in people who drink water contaminated with cysts. Water purifiers that remove cysts require micrometer filters equipped with advanced technology.
It is recommended to use water purifiers that can remove at least 99% of cysts. Water purifiers used in public treatment plants cannot remove or screen for cryptospores.
With this information, you can easily compare water purifiers with other water purifiers, as all the contaminants listed here can be found on the product data sheets. A household water purifier is not a luxury. You and your family need clean water, so do something now.
