Is ultrafiltration or reverse osmosis better for water purifier?

The reverse osmosis water purifier is better, the filtration accuracy is higher, and the filtered water is cleaner.

The filtration precision of reverse osmosis water purifier is 0.000 1 micron, which is the highest filtration precision membrane at present and its service life is about 2 years. Therefore, the manufacturing cost of this kind of membrane is relatively expensive, which brings inconvenience that it needs to be plugged in and will produce a certain amount of concentrated water. But this concentrated water can also be used to water flowers and flush toilets. Compared with the water wasted in bathing, the concentrated water produced by the water purifier is really nothing to mention.

Ultrafiltration water purifier can remove almost all sediment, rust, bacteria, visible suspended solids, algae and macromolecular organic matter in water through the high-precision physical purification process of ultrafiltration membrane. Most ultrafilters adopt three-layer structure, such as pre-PP filter element, ultrafiltration filter element and post-activated carbon, in which PP filter element needs to be replaced in about 3-6 months, and the service life of ultrafiltration filter element can last about 12-24 months according to the use situation.

Misunderstanding of purchasing water purifier

1, the more filter elements, the better, and the more stages, the better.

When buying a water purifier, some people think that the more filter elements there are, the better the purification effect will be. That was not the case. For example, there are many filter elements, but the quality of the filter elements is not high, and no matter how many, it will not play much role. In addition, regarding the number of filter elements, it is best to use 5-6 filter elements for household water purifiers, and try to use disposable filter elements in the last stage of drinking water filtration to avoid secondary pollution.

2. The filter element cannot be replaced for a long time.

No filter element can be replaced for a long time, although some merchants claim that the filter element of water purifier will not be replaced for 3-5 years, which is actually an exaggeration. Don't believe it. The service life of filter element is affected by water quality and frequency of use, and it is usually replaced once a year.
