Anonymous users2024-01-231. Look at the material.
There are currently materials such as stainless steel, fiberglass, cast iron, aluminum, food-grade resin or PVC for water purifiers on the market. The first three are materials with good pressure resistance and can be used as pre-filters (machines). The latter two are materials with poor pressure resistance, and can only be used at the back end of the pre-filter (machine) and used as a direct drinking machine.
Among these materials, stainless steel is better in compressive resistance and corrosion resistance, and the price is relatively high, while food polar resin or PVC has poor compressive resistance and is relatively low.
2. Set the function.
When choosing a water processor, you must first clarify your purpose, first of all, in terms of the big concept, whether you want to purify water or soften water. Purified water is to remove sediment, impurities, bacteria, heavy metals, residual chlorine, organic matter and some minerals from water. Demineralized water is the removal of calcium and magnesium ions in the water, which is directly called scale.
3. Select filter material.
At present, the main water purification materials commonly used are PP cotton, activated carbon, KDF, ultrafiltration membrane, RO membrane (reverse osmosis membrane, reverse osmosis membrane), quartz sand, maifan stone, infrared mineralization ball, etc. Different water purification materials will produce different purification effects, and consumers can choose a suitable water purifier according to the purification effect they want.

Purified water is generally installed under the kitchen dishwasher, there is a pre-filter which is installed in the position of the main water pipe, the function of the pre-filter is to filter out the sediment, impurities, and other large particles in the water! The filtration accuracy can reach 5%-7%. The filtration accuracy at the end can reach 10000 1, but the water storage is not large, if the water consumption is large, you can consider installing a central water purification to solve the water problem, I hope to help you. >>>More
