Is it necessary to buy an air purifier? Check these three points before you buy!air purifier covid company

　　Due to various reasons, many people think that the role of air purifiers is exaggerated and not so practical. In fact, this just means that they have less knowledge about air purifiers, and they may be misled into buying inferior air on the market. Purifier products, which led to their poor impression of air purifiers. Air purifiers have been constantly updated, and from the very beginning they could only purify smog and “upgrade” PM2.5, and added the removal of formaldehyde, toluene, smoke, odor, pollen, pet hair, sterilization, etc. More features. In addition, these three points are also very necessary to understand for everyone to choose the right air purifier.

　　1. Air purification technology

　　At present, the mainstream air purification technologies of air purifiers are generally divided into five types: photocatalyst, negative ions, active manganese, negative ions, and activated carbon. Different air purification technologies purify different air pollutants. For example, negative ions have better purification and dust removal effects, can reduce the harm of second-hand smoke, improve the prevention of respiratory diseases, improve sleep, anti-oxidation, anti-aging, etc.; The sheet, HEPA filter, photocatalyst, etc. form a patented technology of the core filter element of an air purifier, which is a cheaper, environmentally friendly and efficient means of removing aldehydes. It can effectively decompose formaldehyde directly into carbon dioxide and water, and the formaldehyde removal rate is as high as 98%, and there is no secondary pollution; activated carbon has obvious adsorption effect on organic gases, such as toluene and various gas pollutants such as benzene, and its adsorption capacity can be to about 50%.

　　2. Air inlet and outlet design

　　At present, there are many brands of air purifiers on the market. Different brands will adopt different air inlet and outlet designs, such as top inlet and outlet designs, side inlet and outlet designs, and 720-degree wrap-around air inlet and outlet designs. Different air inlet and outlet designs will affect the air purification effect. There are some differences. For example, the top-in and out-air design can speed up indoor air circulation, but it is not suitable for users who have pets at home, and the top-in and out-air design will also cause the problem that the particles floating in the air cannot settle; It is a good solution to this problem, but the coverage is relatively limited; the 720-degree surround three-dimensional air inlet and outlet design avoids the coverage problem, but this type of air purifier is relatively rare because its cost is relatively high.

　　3. Cost of consumables

　　As we all know, most of the air purifiers on the market use filter elements and filters to filter and purify air pollutants. Because of the precipitation of technology, the current filter element can be used for a long time, but the filter screen is limited by technology and needs to be replaced regularly. Therefore, the replacement cost of the filter screen has become the focus of the cost of consumables for the air purifier. At present, the replacement cycle of mainstream air purifier filters is generally 6-12 months, and the price basically ranges from 100-300, so this part of the cost should be considered before purchasing an air purifier.
