6. Choose according to water quality.
The water hardness in different regions is different. The high hardness water in northern China and the limestone areas in the south have high calcium and magnesium ion content in the water, which is prone to scaling. You should choose an advanced filtration water purifier with an ion exchange resin filter element.
For city tap water that contains chlorine, has a strong color and odor, and contains a lot of organic matter, you can choose a household water purifier with a larger amount of activated carbon. Because activated carbon has a strong adsorption effect on residual chlorine, strange colors and odors in water, it has a significant removal effect on organic matter.
For purification of turbid tap water in urban and rural areas, a household water purifier with dual functions of coarse filtration and fine filtration should be purchased. For those whose water is seriously polluted, require complete filtering of any impurities in the water, and drink directly without heating, a reverse osmosis pure water machine should be purchased.
7. Some basic principles for choosing a water purifier:
Water purification products are cost-effective: the product has good quality, stable performance, is more convenient to use, has lower maintenance costs and operating costs, and has a strong Professional technology and good after-sales service.
Choose soft water products for domestic water and water with a certain hardness for drinking water.
In areas where the water hardness is / or below, it is best to choose a composite ultrafiltration machine.
In areas where the water hardness is within the range, it is best to use soft water for showering and laundry, and compound ultrafiltered water for direct drinking water.
For showering in areas where the water hardness is above water.
For water in areas containing high fluorine, high salt, and high sulfur, choose a pure water machine as direct drinking water and supplement trace elements.
In areas with heavy groundwater, sand and rust, it is recommended to install a precision filter after the general meter
