What is a reasonable price for an air purifier?mini air purifier price

　　At present, the price of air purifiers on the market can generally be divided into four stages: below 1000, 1000-3000, 3000-6000, and above 6000.

　　For air purifier products below 1,000 yuan, the purification effect is limited, and because of its low cost, the filter and motor functions may be relatively lacking. Of course, some air purifiers with a relatively small purification area are still good. If your home is moderate in size and the air pollution is not serious, it is more appropriate to choose this.

　　Products around 1000-6000 are suitable for most households, and air purifiers in this price range may have slightly different materials and performance. At this time, we can choose according to our own family situation; for families with higher air purification requirements and better economic conditions, of course, the higher the performance, the better, but don't be fooled by its illusion. It is necessary to compare according to the new national standard, but choose the appropriate one.

　　As for those with more than 6,000, the brand effect and celebrity effect are very important at this time. Because this type of air purifier is prohibitive for us little people. Only those with particularly wealthy families will consider it. Among these people, when buying an air purifier, you have to buy high-end brands and celebrities. Whether the real purification efficiency meets this price does not need to be considered at all.

　　2. How to judge the real performance of the air purifier?

　　To judge whether the performance of an air purifier is real, we judge its "heart" and "lungs". That is its filter and motor. The quality of the filter screen determines the thoroughness of air purification. The motor determines the efficiency of purification. As for the "three highs and one low" that we often say, it is closely related to the two.

　　How are the grades of common filters in air purifiers divided?

　　The filter screen in the air purifier is a very important part. The "three highs and one low" selection method promulgated by the new national standard is closely related to it. It can be said that the filter screen is thinking of the "lung" of the air purifier, while Is the air coming out of the "lungs" fresh and clean? It all depends on the filter. And what are the filters in the air purifier? How are the filter grades divided? I believe that the majority of consumers are ignorant. So let's learn about the filter together.

　　Common air purifier filters generally include pre-filters, activated carbon meshes, HEPA meshes, and photocatalyst meshes. They can purify different pollutants in the air. It is their purification method of division of labor and cooperation that greatly reduces the pollutants in the air. This releases fresh air. Let's take a closer look at these filters and whether they are graded.

　　1. Pre-filter: Its classification is similar to the primary filter, which are G1-G4. The pre-filter is the latest developed micro-mesh dust filter. Its mesh area is smaller than the general one, except that it can In addition to adsorbing small dust particles, it also effectively removes hair. The surface purification is treated with flusosol, and the dust attached to the surface of the filter can be easier to clean. Specifically divided into:

　　G1 primary filter efficiency: initial resistance 25 efficiency 40%

　　G2 primary filter efficiency: initial resistance 25, efficiency 70%

　　G3 primary filter efficiency: initial resistance 35 efficiency 85%

　　G4 primary filter efficiency: initial resistance 45 efficiency 90%

　　2. Activated carbon mesh: Activated carbon filter is a component that truly removes toxic gases such as formaldehyde. All air purifiers that effectively remove toxic gases are activated carbon. Activated carbon filter is currently the only world-recognized healthy variety for removing toxic gases. Widely used in special industries such as firefighting, hospitals, and toxic gases. Its filtration level is directly related to the amount of activated carbon, and the more the content, the more thorough the purification.

　　3. HEPA net: The main function of HEPA net is to filter particulate matter in the air and prevent respiratory diseases. HEPA filters are classified into various grades such as E10 to U17. For fine particles with a diameter of 0.3 microns or more, the filtration efficiency ranges from 99.7% to 99.9999%. Among them, EPA10-EPA12 are called sub-high efficiency air filters that filter particulate matter; HEPA13-14 are called high efficiency air filters. ULPA15-17 is called an air filter with extremely low transmittance.

　　The H13 grade HEPA filter can achieve a total efficiency of 99.95. For H14, the total efficiency of the HEPA filter can reach 99.995%. The total efficiency of the U-level HEPA filter is higher, up to 99.999995 of the U17.

　　4. Photocatalyst net: Photocatalyst air purifier, which belongs to a kind of activated carbon, adopts high-tech photocatalyst technology to eliminate and purify poisonous gases, bacteria and various micro-pollution sources in the air, with strong adsorption and decomposition power, which can effectively inhibit The reproduction of molds and microorganisms, and has the function of regulating humidity. According to its own unique adsorption principle, it can adsorb formaldehyde, benzene series, TVOC, ammonia, radon and other harmful gases and planktonic bacteria in the air. It has the functions of deodorization, deodorization, dehumidification, disinfection and sterilization, air purification, etc., which can lead to the death of adsorbed bacteria and molds without suitable living environment, so as to achieve the purpose of purifying indoor air and inhibiting bacterial infection. Its level of purification is also related to its content.
