In fact, many of the initial 3M models, are microfiltration level, (but can not help but say that the accuracy of the cartridge, and activated carbon technology is indeed more cattle) but do not forget that, at the root of it, he is still a "microfiltration" level! So your feeling will say that 3M's filtration effect is not good! Is very normal, there are manufacturers of mineral water in fact also right, this is a balloon topic, tap water also contains certain minerals, so a certain point of view, tap water is also mineral water! It's just not a reliable sale to fool you! And now go to some of the 3M stores can also be seen, the store displays a high proportion of pure water machine, all manufacturers are just catering to the market, just to the complexity of China's water quality, or pure water machine is a little more reliable. Next, we mainstream several water purification products on the market, do an analysis and purchase! Length is a bit long! On the market now "mainstream" water purification equipment, broadly divided into: ⒈ "pre-filter", built-in stainless steel filter, commonly known as the "front" generally installed next to the water meter! Accuracy of 90-100 microns or so, mainly to filter some of the large filters in the water, such as some bugs, pipeline rust and so on. Effective then: generally with the central water purifier, water softener, water purifier, etc., mainly to prevent "large particles" clogging supporting water purifier. It is not recommended to use alone, the effect is not great. And the price difference is large, Smith, 3M foreign brands, generally around $ 1,000, domestic cheap about 100, it is recommended that the home is equipped with a water purifier, you can install a moderately priced, because it is to play with the war, about 200-300 or so for good! Pake "faucet simple filter" The cartridge has mostly 5-level filtration, respectively, stainless steel, ceramic cartridge, activated carbon, PP cotton, stainless steel. On the smallest aperture of the ceramic cartridge filtration accuracy of about 0.5 microns. Can filter sand and rust, and part of the suspended solids! This is not much to introduce, because the effect is general, on Taobao, the basic price between 60-200. Want to try is not expensive, but not recommended, because the cost-effective, hollow fiber under the kitchen ultrafilter prices than the similar, probably around 500 is quite good, the filtration effect will be much better than this! ⒊"中空纤维超滤机" filtration accuracy of 0.01 microns, now the main derivatives of this technology for two types of products, a class of small under-the-kitchen, usually also 5 levels, roughly PP cotton + granular activated carbon + compressed activated carbon + hollow fiber ultrafiltration membranes + post activated carbon. One class belongs to, central water purifier, stainless steel shell, large flow rate. Can reach about 3000L per hour, usually installed after the pre-filter! Whole house purification. But it is not recommended to drink raw. These two categories are basically ultra-filtration series, to 0.01 micron pore size, can filter most of the suspended solids, sediment, colloidal organics, etc., because the smallest bacteria in the 0.02 micron or so, so it is not up to the requirements of direct drinking, there are businesses to confuse, will say that the ultra-filtration water purifier will retain the trace elements in the water, but the retention of trace elements, at the same time, some of the small bacteria and heavy metals will be retained! Water with bacteria and heavy metals is not drinkable! Singed "Centralized Water Softener, Centralized Water Purifier" water softener uses ion exchange method to soften the water, effectively removing scale and increasing the life of the water heater and piping. Soften the water quality, bathing, washing the face has a certain effect of nourishing the skin, high security, but do not use as drinking water, high sodium ion content Central water purification using activated carbon and KDF55 as the filter material activated carbon adsorption KDF to remove heavy metals, but the zinc ions will be exceeded the best not to drink the big harm to the best not to drink, the small expensive!
Cost-effective! It is recommended for rich people!
