You have a need for a water purifier, I think the main thing is that you are not satisfied with your current drinking water quality.
Domestic water quality is mainly faced with poor water sources, pipeline pollution and secondary pollution.
So at home, the main function of the water purifier is to filter.
The main function of foreign water purifiers is to improve water quality, filter cartridges are mostly activated carbon (55 ~ 60μm) and microporous membrane (polyethylene 0.5μm), as well as some coarse filtration or enhance the taste of the material. The filtration function is not easy to withstand the domestic environment of serious pollution.
Additionally whoever advertises with you that the water purifier has health care functions, hurry up and retreat. Because of the exaggerated propaganda generally have ghosts.
And in addition, now many domestic fake foreign devils brand, more not worth mentioning. The same more is labeled in their own pedigree in how foreign brand, surely either is not real product is not selling, or hanging sheep's head to sell dog meat.
So you're looking for a water purifier, you can go to understand the better filtration function, the reputation of the brand is more hard, this thing depends on the consumer word of mouth. At least other people use more, and said good products, can be more assured.
In a word, suitable for your use of the environment is the best.
Of course, if you need to filter chlorine, add activated carbon, and so on and so forth.
