Water softener and water purifier which is better

Summary: There are very many water purification devices on the market, water purifier and water softener are two water purification devices that we use more in our daily life. Water softener is an appliance that reduces water hardness through ion exchange technology. Water purifier is the use of ultrafiltration membrane separation technology, remove harmful substances of an appliance. The two are different in addition to the principle of function and maintenance, there are also many differences, consumers can choose according to the actual needs of the next and Xiaobian take a look at it. Water softener and water purifier difference

1, working principle

Water softener commonly used water softening technology there are two kinds, one is through the ion exchange resin to remove calcium and magnesium ions in the water, reduce water hardness; the other is the nanocrystalline technology, the use of nanocrystals generated by the high-energy, the free calcium, magnesium, bicarbonate ions in the water packaged into nanometer-sized crystals, thus preventing the free ion Generate scale.

The water purifier is the use of 0.01 micron ultrafiltration membrane separation technology, through the physical way of filtration and adsorption, to go to the tap water in the chlorine and due to the secondary pollution of bacteria, viruses, colloid, rust, impurities and other kinds of harmful to the human body of organic pollution.

2, functional use

Water softener is mainly soften water, remove water alkali in the water, can not drink directly, belonging to the domestic water, laundry, shower, beauty and skin care effect. Water softener can not remove impurities, bacteria, viruses and heavy metals in the water.

The water purifier can filter out impurities in the tap water, rust, bacteria, viruses, colloids, etc., and finally out of the water to meet the standards for drinking water, retaining the tap water in the minerals useful to the human body, but can not be drunk directly, boiled and then drink better. Water purifier can not remove calcium and magnesium ions in the water, the problem of limescale can not be solved.

3, maintenance

Water softeners commonly used for the resin softener, in the ion exchange to produce a certain amount of soft water, the resin adsorption of hardness ions will be saturated, which requires resin regeneration, through the regeneration of materials (water softener salt) replacement of hardness ions within the resin, so that the softener can continue to use.

More water purifier selection of activated carbon, meltblown core, microporous ceramics, hollow fiber, KDF and other cartridges to purify water, the cartridge has a certain service life, the need for regular replacement and maintenance. Activated carbon is generally replaced once every two years, KDF filter is generally replaced once every three years.

Which water softener and water purifier

Water softener and water purifier are two completely different water purification equipment, a variety of different features, water softener can only filter calcium and magnesium ions, soften water, filtered water can not be drunk, more used in the bathroom. Water purifier can filter a variety of harmful substances, water can drink, mostly used in the kitchen. If you are in the area of the water body is relatively hard, wash out the clothes hard and astringent, water appliances have been plagued by scale for a long time, it is recommended to buy a water softener. If you have high requirements for kitchen water and drinking water, it is recommended to buy a water purifier. If your economic conditions allow, it is also good to buy a set of full-featured whole-house water purification.
