According to the water quality, choose the water purifier to teach you the practical purchase of 7 rules.

It is everyone's knowledge that tap water can't be drunk. Recently, with the increasing attention to home health, the use of water purifiers has also been popular among you, but how to buy them in the face of many brands and types on the market. It is also a problem to get a suitable water purifier. Xiao Bian reminds everyone that it is important to choose a water purifier based on water quality.

The higher the graded filter series, the better the water purification.

To learn to choose a water purifier, you may first understand the principle of water purifier classification. The beautiful water purification expert from the beautiful scenery told the Chengdu Business Daily reporter that the water purifier was divided into single-stage filtration, two-stage filtration, three-stage filtration, four-stage filtration and five-level filtration and above.

Single-stage filtration is only suitable for high-quality drinking water sources. Generally, the tap water source cannot be drunk after being filtered. Two-stage filtration, partially removing organic and inorganic impurities, can effectively adsorb residual chlorine in water, improve the taste of water, and only apply to high-quality drinking water. Better than single-stage filtration. Generally, the tap water source cannot be drunk after being filtered. Three-stage filtration to clarify the water source.

According to the above, it is not difficult to see that the higher the filtration grade, the better the water quality of the filtration.

It is important to choose a water purifier based on water quality.

Lei Biwei, the sales director of Huashang HVAC, told the Chengdu Business Daily reporter that through the feedback from the sales feedback, consumers have basically done some preliminary understanding when consulting the water purifier, but they rarely remedy the problem according to the water quality problem.

Lei Biwei said that due to the difference in regional water quality, in fact, it is not suitable for their own use. For example, in Chengdu, many people find that the kettle is prone to scale, which is the hard water quality. High-hardness water quality in northern China and limestone areas in the south have high levels of calcium and magnesium ions in water and are prone to scaling. Advanced filtration water purifiers with ion exchange resin cartridges should be purchased.

In urban water with chlorine, heavy color and odor, and organic content, you can purchase household water purifiers with more activated carbon. For tap water purification with turbid water quality in urban and rural areas, household water purifiers with dual functions of coarse filtration and fine filtration should be purchased. For serious pollution in water, it is required to thoroughly filter out any impurities in the water. If you do not need to drink it directly, you should purchase a reverse osmosis pure water machine.

Tuen Mun purchase 7 rules to help you choose

In addition, Chengbai IKEA's water purification professionals have summed up a series of “laws” for purchasing water purifiers.

1. Pay attention to cost performance: the quality of the product is good, the performance is stable; the use is convenient; the maintenance cost and running cost are low; there is strong professional technology and good after-sales service.

2, the use of soft water products for domestic water, drinking water to choose a certain hardness of water (140mg / L - 200mg / L), soft water and pure water is not suitable for long-term drinking water.

3. It is best to choose a composite ultrafiltration machine for water hardness below 170mg/L.

4, the water hardness of 170mg / L -250mg / L of the area shower, laundry water is best to use soft water products, direct drinking water is best to choose composite ultrafiltration water products.

5, the water hardness in the area above 250mg / L shower, laundry water is best to use soft water products, direct drinking water to select part of softened water (softened water and unsoftened water mixed in a certain proportion) ultrafiltration after filtration through a composite ultrafiltration machine water.

6, water containing high fluoride, high salty, high sulfur area, choose pure water machine, as a direct drinking water, and add trace elements.

7. In areas where groundwater or sand and rust are heavy, it is recommended to install a precision filter after the main table.

Misunderstanding these views are not reliable

Finally, the Chengdu Business Daily reporter summed up the four misunderstandings about the selection of water purifiers based on the opinions of the beautiful water comforters, Huashang HVAC, and Chengbaixin IKEA water purification professionals.

Myth 1: The more product filters, the better the filter is not. Professionals suggest that the last filtration of drinking water should use disposable filter elements as much as possible to avoid secondary pollution.

Misunderstanding 2: Only look at the brand does not consider professional household water purification, especially the direct drinking water. The complexity is a team that needs professional strength research and development, so we try our best to choose the brand of water purification equipment made by professional water purification companies.

Myth 3: Activated carbon filtration technology is outdated. Activated carbon is the best filter adsorption material in nature. If you do not use activated carbon, no matter how high the filtration accuracy is, the taste of the water will be compromised.

Misunderstanding 4: The filter element can be replaced for a long time, and the filter element that will be blocked is a good filter element, which also shows that the water purifier is indeed effective. The market claims that the filter element does not need to be replaced for 3 to 5 years, and it is often exaggerated.

Xiao Bian summary: The use of water purifiers is to be able to live a healthier life, so be sure to pay attention to these misunderstandings in use, in order to avoid self-defeating.
