Water buy 1, different water hardness in different regions of northern China and southern high water hardness limestone areas, the price of household water purification equipment, water calcium and magnesium ion content high, easy to scale, should buy with an ion exchange resin filter Advanced filter water purifier. 2, water, chlorine, heterochromatic odor heavier, the role of organic matter content of more urban water, household water purifier, activated carbon can buy more loads of household water purifiers. Because the activated carbon to chlorine, heterochromatic smell there is strong adsorption of organic matter removal efficiency significantly. 3, for the urban and the water is muddy water purification, should buy coarse filter, fine filter dual function of home water purifier. For serious water pollution, requires completely filter out any impurities in the water, no heating drinkable, should buy reverse osmosis water. Most of the water purifier is the use of the principle of progressive resistance sieve structure manner, the multi-stage filter inclusive concatenation, precision filters sequentially arranged from low to high, household water purifiers, in order to achieve a multi-stage filter trapping dirt apportionment, thereby reducing filter clogging and artificial drainage, and extend the number of washable filter replacement cycle. There is also a new design idea is to apply the principle of dual circulation self-cleaning structure the way it is designed to provide as much thinking is no longer space for hiding dirt pollutant, but take sub-quality principle, a small isolated part of the clean water, while as usual as far as possible the flow of raw water flow together with the water quality in a timely manner so that dirt is taken away, to water does not rot. This will not only get purified water, they will not or can not easily precipitate dirt in the machine to avoid the formation of secondary contamination and greatly reduce the filter loss, better water quality and more secure and energy-efficient low-carbon.
