What is the guiding significance of the national standard for water efficiency grade of water purifi

China's national industry standards for water purifiers were promulgated in 2013, including "Special Requirements for Safe Ultraviolet Radiation Water Treatment Appliances for Household and Similar Electrical Appliances" and "Special Requirements for Safe Hot and Cold Water Dispensers for Household and Similar Electrical Appliances";

Ultraviolet sterilizer for household and similar water purifiers", "Household and similar use reverse osmosis water purifiers, nanofiltration water purifiers for pressure tanks" four net drawbacks and losses of water purifiers, national water purifiers, home water purifiers, and water purifier industry standard air silver drafting work meeting was held in Kunming, Yunnan Province on May 17 19, 2013.

Among these four standards, the first two are national standards for water purifiers, which are mandatory safety standards; The latter two items are industry standards and are recommended product standards.

Thank you! As an engineer working for a water company, I am very happy to answer your questions about the national standards for water purifiers.

The national standards for water purifiers mainly include the following aspects. First of all, the filtration effect of the water purifier must meet the relevant water quality indicators. This means that the water purifier needs to be able to effectively remove harmful substances such as suspended solids, bacteria, viruses, and heavy metals in the water to ensure the provision of safe and clean drinking water.

Secondly, the material and design of the water purifier also need to meet national standards. Water purifiers should use materials that meet hygienic standards to ensure that the water does not pollute the water during treatment. In addition, the design of the water purifier should be easy to install and maintain, and have the necessary safety protection measures to avoid potential accidental injuries.

In addition, the state also requires water purifiers to meet relevant standards in terms of service life, pressure resistance, and leak-proof performance. This is to ensure that the water purifier can work stably for a long time under normal use conditions and effectively provide clean and healthy drinking water.

In general, the national standard for water purifiers aims to ensure the safety and health of drinking water for the public. By setting these standards, you can ensure that the water purifier products on the market have a certain quality assurance, and consumers can choose products that suit their needs according to the standards.

Hope mine is helpful to you! If you have any other questions, please feel free to ask. Thank you!

The water test value of the water purifier is generally normal if it is below 50. Water purifier, also known as water purifier and water purifier, is a water treatment equipment that carries out deep filtration and purification of water quality according to the requirements for water use. The water purifier that is usually talked about refers to a small purifier used for home use.

The core technology of the water purifier is the filter membrane in the filter element device, and the current return technology is mainly in the ultrafiltration membrane and RO reverse osmosis membrane. The water purifier can effectively filter out rust, sand and gravel, colloids in the water, and adsorb residual chlorine, smell, discoloration, pesticides and other chemicals in the water. It can effectively remove bacteria, germs, toxins, heavy metals and other impurities in water.

The value of the national drinking water standard water TDS pen test is within 0-50, indicating that the water is clean water, which can be drunk directly, the water quality is clean and impurity-free 50-100 water is the standard of bucket water, the value of 100-200 is the water quality of tap water, relatively speaking, 200-300 is slightly polluted water, long-term drinking may cause a bad impact on the field, more than 300 water is polluted water, there are more impurities in the water, and it is not beneficial to the body if you drink it.

Summary. First-class water efficiency: First-class water efficiency means that the water purifier can remove most of the suspended solids, organic matter, heavy metal ions, bacteria, viruses, etc. in the water, but cannot remove chloride ions, fluoride ions and other harmful substances in the water.

Secondary water efficiency: Secondary water efficiency means that the water purifier can remove most of the suspended solids, organic matter, heavy metal ions, bacteria, viruses, chloride ions, fluoride ions and other harmful substances in the water, so as to achieve a higher water purification effect. In short, the first-level water efficiency can only remove most of the suspended solids, organic matter, heavy metal ions, bacteria, viruses, etc. in the water, while the second-level water efficiency can remove more harmful substances in the water, so as to achieve a higher water purification effect.

First-class water efficiency: First-class water efficiency means that the water purifier can remove most of the suspended solids, organic matter, heavy metal ions, bacteria, viruses, etc. in the water code, but cannot remove chloride ions, fluoride ions and other harmful substances in the water. Secondary water efficiency:

Secondary water efficiency means that the water purifier can remove most of the suspended solids, organic matter, heavy metal ions, bacteria, viruses, chloride ions, fluoride ions and other harmful substances in the water, so as to achieve a higher water purification effect. In short, the first-level water efficiency can only remove most of the suspended solids, organic matter, heavy metal ions, bacteria, viruses, etc. in the water, while the second-level water efficiency can remove more harmful substances in the water, so as to achieve a higher water purification effect.

Can you tell us more about that?

First-level central water efficiency: First-level water efficiency refers to the ability of the water purifier to remove organic, inorganic, heavy metals and other pollutants in the water, so that the water can reach a certain purification standard. Secondary water efficiency:

Secondary water efficiency means that the water purifier can remove microorganisms, viruses, bacteria and other pollutants in the water, so that the water can reach a higher purification standard. Reasons for the problem:1

The replacement of the water purifier filter element is not timely: the replacement cycle of the water purifier filter element is generally 6-12 months, if the filter element is not replaced in time, it will lead to the poor purification effect of the water purifier and the water quality will be polluted. 2.

Improper replacement of water purifier filter element: The replacement of water purifier filter element needs to be carried out in accordance with the correct steps, if it is not replaced properly, it will lead to poor purification effect of water purifier and water pollution. Workaround:

1.Replace the filter element in time: Replace the water purifier filter element regularly to ensure the purification effect of the water purifier.

2.Replace the filter element correctly: When replacing the filter element of the water purifier, the correct steps should be followed to ensure the purification effect of the water purifier.

Personal Tips:1Regularly inspect the water purifier:

Regularly inspect the water purifier to ensure the proper operation of the water purifier. 2.Replace the filter cartridge regularly:

Replace the water purifier filter element regularly to ensure the purification effect of the water purifier. 3.Replace the filter element correctly:

When replacing the filter element of the water purifier, the correct steps should be followed to ensure the purification effect of the water purifier.

Does the water filtered out of the water purifier contain minerals?

Does the water filtered out of the water purifier contain minerals?

I can't hear the voice, can you type.

The water purifier with reverse osmosis function filters out all the harmful and beneficial minerals in the tap water, so there are no minerals. Even the mineral water sold on the market uses reverse osmosis to filter out all the harmful and beneficial minerals, and then add beneficial minerals to the cherry blossoms. In fact, there are not many beneficial minerals in the water, and the minerals are replenished enough when eating.
