The national color and the noble water purifier are good

What brand of household water purifier is good? It's important to master the method.

First, look at the qualifications. The Health Supervision Center of the Ministry of Health of the People's Republic of China has clearly issued the measures for the supervision and management of drinking water hygiene. Consumers can go to the public network of health administrative licensing for inquiries when purchasing.

Second, look at the material. Materials such as stainless steel, fiberglass, cast iron, aluminum, food-grade resin or PVC are currently available on the market. The first three are materials with good pressure resistance, which can be used as pre-filters (** machine).

The latter two are materials with poor pressure resistance, and can only be used at the back end of the pre-filter (** machine) and used as a direct drinking machine. Among these materials, the compressive resistance and corrosion resistance are relatively high for the purpose of stainless steel, and the compressive resistance of food-grade resin or PVC is poor, and the compressive resistance is relatively low.

3. Define the function. When choosing a water processor, you must first clarify your purpose, first of all, in terms of the big concept, whether you want to purify water or soften water. Purified water is to remove sediment, impurities, bacteria, heavy metals, residual chlorine, organic matter and some minerals from water.

Demineralized water is the removal of calcium and magnesium ions from water.

Fourth, the selection of filter material. At present, the commonly used water purification materials mainly include PP cotton, activated carbon, KDF, ultrafiltration membrane, RO membrane (reverse osmosis membrane, reverse osmosis membrane), quartz sand, maifan stone, infrared mineralization ball, etc. Different water purification materials will produce different purification effects, and consumers can choose a suitable water purifier according to the purification effect they want.

Fifth, the size of the ratio. Water purifiers are generally based on the instantaneous water output to determine the model, more than 20 tons of hours can be called ** water purifier, less than 10 tons of hours can be called direct drinking water purifier. And this water output is related to the volume and the diameter of the water inlet and outlet, usually the larger the water purifier, the larger the instantaneous water output.

Sixth, than the service. The first is the pre-sale service for the installation of water purifiers, according to various factors such as different regional water quality, different waterway design, different room sizes, etc., we should give a more complete purchase suggestion and ask about the use effect after installation, and then make improvements according to the customer's requirements. In addition, leakage caused by various reasons in the use of water treatment materials is possible, so it is also necessary whether the water purifier is insured by the insurance company.

As the saying goes, "if you are not afraid of 10,000, you are afraid of what if", when there is an accident, the insurance company will pay according to the customer's loss.

I've never heard of it, look at the brand. Look at the service.

A, you can open ** to see if they are registered.

Now there are thousands of water purifiers on the market, you can learn more.

Water purifiers can be divided into many types according to different purification principles and processes. Among them, RO reverse osmosis technology has the highest filtration accuracy (filtration accuracy in microns), because the pore size of the reverse osmosis membrane is only 1/100,000 of the diameter of a human hair, only water molecules and dissolved oxygen are allowed to pass through, and all impurities contained in the water such as pesticides, bacteria, viruses, heavy metals and other harmful substances are almost all intercepted and eliminated. In addition to reverse osmosis, there are many other filtration technologies:

Nanofiltration (filtration accuracy between microns), ultrafiltration membrane (filtration accuracy between microns), fine filtration (filtration accuracy below microns, such as ceramic filtration, PP cotton filtration, etc.).

For the reverse osmosis water purifier market retail ** generally 2000 yuan, more than 2000 brands with good brands, less than 2000 yuan with poor brands, and about 1500 yuan for some brands, you can refer to it. The ultrafiltration machine is cheaper, a few hundred yuan, and the expensive one will not exceed a thousand.

There are two sentences in the famous poet Liu Yu Duxi in the Tang Dynasty in "Peony Poems": "Only the peony is really colorful, and the flowers move the capital when they bloom." The previous answer is that among the flowers, only the peony flower can be called the national color and deserved.

But Liu Yuxi only mentioned "national color" and did not mention "Tianxiang".

Li Zhengfeng's peony poems include the national colors and heavenly fragrances. According to the "Records of Differences", during the Taihe period of Tang Wenzong, when Tang Wenzong was admiring the peony flowers in the inner hall, he suddenly asked Cheng Xiu beside him, which peony poem was written by the master of Beijing, which one was the most beautiful? Cheng Xiu has already believed that Li Zhengfeng, a scholar from the Chinese Academy, should be the most expressive.

Since then, "national color and natural fragrance" has become a proper noun to praise peony flowers.

Yellow is the most noble color of Chinese tradition since ancient times, and it is naturally the national color.

"BMW Xiangche" is more exact!
