It is necessary to pay attention to the purchase of water purifier products. There are too many brands of water purifiers in the market now, and there are many problems to be paid attention to. We can't just look at the price. After buying the household water purifier products, it is not like a TV set or a drinking water machine. It is used when you go home. This product also involves lifelong after-sales, such as replacing filter elements and cleaning filter elements. Good after-sales is 3 months of cleaning, remind replacement, free service. However, it depends on whether local dealers can do it, regardless of the brand size. China's brand or foreign brand is basically none of them are completely self-produced, basically are assembly-based factories. However, those with better brand should pay attention to some in the process of production and testing. The production and testing of the brand is worse than that of the brand. All of these ultimately depend on the after-sales capacity of local dealers, How familiar the installer is.
As we all know, the water purifier is certainly a third of the finished product when it is delivered. The quality of the sales and installation determines whether the product is a good product in the consumer psychology, and also accounts for one third of the finished products. The last third is to be used by the user. Of course, besides the high-quality after-sales service, we also need to see the configuration of the products.
1. filter element configuration (very important): if you buy RO, it mainly depends on RO directly affecting the quality of water quality. Generally, the films of Shihan and Dow are better, and the filtration precision of the membrane with good quality is relatively higher, which is suitable for the southern market of China; The filter with lower precision (such as Huitong and fluid film) is suitable for the northern market of China. Water quality in different regions and daily water consumption are very important. In contrast, the north and South markets need to be different in the use of membrane. The quality of UF membrane (UF) should be considered for water purification, especially the ultrafiltration membrane is prone to stink in summer. It is necessary to wash it frequently. In hot summer, it is necessary to wash it every morning and night. Also is ppcotton: press to see if it is strong, good is very real, and it takes a long time; The poor is very soft, a few yuan can buy, take a very short time. Activated carbon: coconut shell activated carbon is the best, if the activated carbon is good, it has strong adsorption capacity and good deodorization effect.
2. booster pump (very important): the reverse osmosis machine mainly relies on the booster pump. If it breaks down, the whole machine will be finished. There are several points to note:
( 1) Moisture proof, water purifier is generally placed in the cabinet, kitchen position, more humid, must be able to moisture-proof.
( 2) Noise, some booster pump noise is very big, when working water buzzing, so choose bass.
( 3) Pressure stabilization, the pressure of domestic tap water is large and small, which will affect the life of RO membrane (RO membrane is the most expensive one in the filter element of the whole machine, and the better one is retail for more than 200 bar.
( 4) The cold resistance ability, which is more important in the north, is low in the north, and the pump which does not resist cold will freeze.
( 5) It is not very important to see if there have been any prizes, but it can also be referred to.
3. filter shell: This is also important, because the filter shell is the only contact between water and filter element.
( 1) Look if it's food grade material. The good filter shell is white, bright and has no taste.
( 2) Pressure bearing capacity, or the pressure in the home is unstable, the filter shell can not withstand the pressure for a long time, and it is easy to break. Generally, the filter bottle with blasting pressure of 25kg is required.
4. I will not tell about the spare parts of water storage tank, faucet and other parts.
