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

the filtration precision of reverse osmosis water purifier is .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 membrane is also expensive, which brings inconvenience that it needs to be plugged in and will produce a certain amount of concentrated water. However, this part of concentrated water can also be used for watering flowers and flushing toilets. Compared with the water wasted in bathing, the concentrated water produced by the water purifier is really not worth mentioning.

Ultrafiltration water purifier can remove almost all the 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. Among them, PP filter element needs to be replaced in about 3-6 months, and the service life of ultrafiltration filter element can be maintained for about 12-24 months according to the use situation.

Misunderstanding in choosing a water purifier

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

Some people think that the more filter elements, the better the water purification effect of the water purifier. This is not the case. For example, there are many filter elements, but the quality of the filter elements is not high, and no amount of them can play a big role. In addition, regarding the number of filter elements, the 5-6 filter mode is the best for household water purifiers, and the disposable filter element should be used as far as possible for the last filter of drinking water, so as to avoid secondary pollution.

2. The filter element can 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 does not need to be replaced for 3-5 years, it is actually an exaggeration. Don't believe it. The service life of the filter element is affected by the quality of water and the frequency of use, and it is usually replaced once a year.
