Choose water purifier by filtration technology

The most important function of a water purifier is to purify water quality and drink healthy and safe water. And the purification effect is the top priority when we buy water purifiers. The purification effect is mainly related to the filtering technology of the selected water purifier. The following are common.

1. PP cotton filter technology

Water purifiers using PP cotton filtration technology are usually made of polyester fiber particles, non-toxic and harmless, more environmentally friendly, and have good corrosion resistance. It can effectively filter the suspended particles in the water such as rust and sediment in the tap water. However, relatively few impurities can be filtered, and the filtering effect is general.
2. Activated carbon filtration technology

Everyone knows that activated carbon has a strong adsorption capacity, so the water purifier using activated carbon adsorption technology can effectively absorb the odor, residual chlorine and some organic matter in tap water. Relatively speaking, it is slightly stronger than PP cotton filter technology.

3. Microfiltration technology

Microfiltration technology is a widely used filtration technology in the field of water purifiers. It is precisely because of microfiltration technology, so its filtration accuracy is not high. Basically, it can filter out the sediment, rust and some particles between 0.1-1μm in the tap water, but it is still powerless to bacteria and heavy metal elements in the water.

4. Nanofiltration technology

The precision of nanofiltration technology is between 0.01-0.001μm, which can not only effectively remove calcium and magnesium ions and harmful substances in tap water, but also retain the minerals in the water that are beneficial to the human body. However, the cost of this nanofiltration technology is relatively high, and it is not yet mature, so it is rarely used.

5. Ultrafiltration technology
Compared with the microfiltration technology, the filtration accuracy of the ultrafiltration technology water purifier will rise to a high level. In addition to basically filtering out suspended solids and rust in water, it can also filter out harmful substances such as bacteria and viruses in tap water.

Although ultrafiltration technology can meet the needs of daily healthy drinking water, heavy metals and residual chlorine in tap water still cannot be removed very well.

6. RO reverse osmosis technology

I believe you will definitely hear the term "reverse osmosis" when purchasing a water purifier. This technology is also a relatively common and high-end filtration technology. The filtration accuracy can reach 0.0001-0.0005μm, and the harmful microorganism impurities larger than 0.02 in diameter can be filtered through the internal reverse osmosis membrane.

And it can effectively filter residual chlorine and heavy metals that could not be solved before. Relatively speaking, this filter technology has the strongest water purifier capacity, but the relative price is higher.

【Shopping suggestions】

In terms of filtration capacity, RO reverse osmosis technology> nanofiltration technology> ultrafiltration technology> microfiltration technology> activated carbon filtration technology> PP cotton filtration technology, so for health reasons, it is not recommended to choose activated carbon or PP cotton filtration water purifier.

If you can choose ultrafiltration and microfiltration technology only to improve water quality, for the elderly and children at home who pay more attention to drinking water health, you can choose RO reverse osmosis technology water purifier.
