How to judge whether the water purifier is good or not? In order to solve this problem, I have learned some answers through online and consulting friends. I hope that I can help everyone not waste money in vain and be squandered by the water purifier sales staff.
1, water purifier shell thickness
The thickness can ensure that the upper and lower casings of the water purifier are precisely combined with minimum error, no gaps, and should not be disengaged during vibration. The large thickness can reduce breakage, cracking, etc. during transportation, and maintain the value of the finished product. Since the wall type water purifier is suspended from the kitchen wall, once it is hung up, the thin water purifier of the casing will gradually deform, thereby increasing the probability of water leakage.
2, water purifier filter shell quality
Filter bottles are not only required to have a corresponding thickness, but also have the toughness to adapt to low temperature and high temperature to prevent brittle cracking and cause loss of water leakage. Good filter bottle thickness and toughness are excellent, even with a hammer is difficult to break. A good brand should strictly implement the filter-removal type (never recycle) to ensure that all the filter elements replaced after sale are original authentic.
3, see the water purifier brand qualification
At the time of purchase, you can go to the public website of the health administrative license to inquire. You can't just listen to the words of the water purifier sales. I believe everyone has also suffered from the sales staff.
4, see the water purifier material
There are currently stainless steel, FRP, cast iron, aluminum, food grade resins or PVC. Among these materials, the pressure resistance and corrosion resistance are best in stainless steel, and the price is relatively high. The food resin or PVC has poor compression resistance and the price is relatively low.
There are several kinds of filter elements commonly available on the market. For this reason, Xiaobian has also made some simple instructions, and I hope to help friends who need to buy water purifier filters.
1. Granular activated carbon: deep adsorption of heterochromatic odor in water, residual chlorine
2, pp cotton: filter out as small as 1 micron pollutants, thoroughly filter rust, sediment, colloids and other impurities, the texture is dense, anti-water hammer impact, greatly improving the life of the overall filter.
3. RO reverse osmosis membrane: effectively removes harmful substances such as heavy metal ions, calcium, magnesium ions, bacterial viruses and chemical residues in water, and the salt removal rate is as high as 96%. Ensure that the produced drinking water meets the standard for drinking water.
