The difference between water softener and water purifier

Functional use comparison
Water softener: Mainly soften water and remove alkali in water. Can't get drunk directly. It belongs to domestic water. It has good effects on washing, showering, beauty and skin care. The use of soft water can prevent various water heaters and central air conditioners from scaling, prevent shower clogging, and extend service life. Water softeners cannot remove impurities, bacteria, viruses and heavy metals in the water. Its function is to remove scale.
Water purifier: The water purifier can filter impurities, rust, bacteria, viruses, colloids, etc. in the tap water. The final water can meet the drinking water standard and retain useful minerals in the tap water, but it is still not drinkable directly Or drink it after boiling. The water purifier cannot remove calcium and magnesium ions in the water, that is, it cannot solve the problem of scale.

Comparison of working principle
Water softener: Through the ion exchange principle of exchange resin, it absorbs calcium and magnesium ions in the water, thereby reducing the hardness of the water, thereby protecting the electric water heater and wall-hung boiler from scaling. When water containing calcium and magnesium ions flows through the resin together with sodium ions, calcium and magnesium ions replace sodium ions and are adsorbed on the resin, sodium ions are replaced with water, and water containing sodium ions flows out from the water softener and becomes Chengshui. "Soft water (less calcium carbonate content".
Water purifier: using 0.01 micron ultrafiltration membrane (hollow fiber) separation technology, through physical method of filtration and adsorption, to remove chlorine in urban tap water and bacteria, viruses, colloids, rust, impurities and other organic pollution caused by secondary pollution Harmful to the human body.

Post-maintenance comparison
Water softener: The commonly used water softener for soft water is resin. After a certain amount of soft water is produced by ion exchange, the hardness ions absorbed by the resin will reach saturation, which requires resin regeneration, and the hardness in the resin is replaced by the regenerated material (soft water salt) Ion, so that the water softener can continue to be used.
Water purifier: Most water purifiers use activated carbon, meltblown filter element, microporous ceramic, hollow fiber, KDF and other filter elements to purify water. The filter element has a certain service life and needs to be replaced and maintained regularly.
