Is it better to buy a water purifier with electricity or without electricity?

Nowadays, the water purifier products are uneven, and consumers also have doubts about the two types of water purifiers that use electricity and do not use electricity. So is it better to buy a water purifier that uses electricity or does not use electricity? .

In fact, water purifiers, as small appliances, are very different from large appliances such as refrigerators and air conditioners. Water purifiers do not rely on high-power compressors to work like refrigerators and air conditioners. The core component of the water purifier, the filter element, does not need electricity when it is working. The only parts of the water purifier that need electricity are computer control chips and indicator lights, and the power consumption is extremely low.

The representative of the water purifier that requires electricity is the RO reverse osmosis water purifier. This type of water purifier needs electricity in the water purification process to produce high-purity water, and this type of electric water purifier has high filtration accuracy. Among them, "electricity" also plays an active role in it.
For example, the pore size of RO reverse osmosis membrane is only 0.0001 microns, and the water pressure of tap water cannot push the water over, so it is necessary to use an electric booster pump to increase the pressure of tap water, so that water molecules can pass through the RO membrane to achieve the purpose of purification. Electric water purifiers cannot work after a power outage and will produce waste water. The maintenance cost in the later period is definitely higher than that without an electric water purifier.
Unplugged water purifiers are generally ultrafiltration water purifiers. The filtration accuracy of ultrafiltration water purifiers is generally 0.01 microns, which can filter out large particles of impurities, bacteria and viruses. Since this type of non-electric water purifier is filtered by the water's own pressure, the filtration accuracy will not be very high, but the filtration capacity will be relatively large.
However, no electric water purifier will produce waste water, the filtration capacity is relatively large, the filter element has a long life, the price is cheap, and the later maintenance cost is also low. Both electric water purifiers and non-electric water purifiers have their own advantages and disadvantages. Home users can decide according to their local water quality, purchase budget and actual water demand.
