Comparison of Water Purifiers With Different Filtration Technologies
At present, the filtration technologies used in water purifiers on the market mainly include microfiltration,
ultrafiltration, nanofiltration and reverse osmosis.
The filtration accuracy of microfiltration technology is relatively low, generally between 0.1 microns and 10 microns, which can remove sediment,
rust, large particles of suspended matter and some bacteria in the water, but can not remove heavy metals
,
viruses and small molecules of organic matter in the water. However, the advantages of microfiltration water purifiers are large water output, low cost,
and no electricity is required.
The filtration accuracy of ultrafiltration technology is between 0.01 micron and 0.1 micron, which can remove bacteria, viruses, colloids,
macromolecular organic compounds, etc., while retaining some minerals in the water. Ultrafiltration water purifier outlet speed is faster,
generally do not need pressure pump, low energy consumption, suitable for better water quality areas,
can meet the daily water needs of families, such as washing vegetables, washing rice and so on.
The filtration accuracy of nanofiltration technology is between ultrafiltration and reverse osmosis,
about 0.001 micron to 0.01 micron, it can remove most of the heavy metals, pesticide residues, organic matter,
etc., while the salt in the water has a certain interception effect, can retain part of the
minerals that are beneficial to the human body, and can improve the taste of water to a certain extent.

Reverse osmosis technology has the highest filtration accuracy, up to 0.0001 micron, and can remove almost all
impurities in the water, including heavy metals, bacteria, viruses, organic matter, salt, etc., the water can be directly drinkable,
and the water quality is high in purity, but the reverse osmosis water purifier requires electricity and will produce a certain amount of wastewater.
