Air pollution has caused people's demand for air purifiers to rise rapidly. The reporter learned from Suning and Gome stores that the consulting volume and sales volume of air purifiers have increased sharply in recent years. Most consumers prefer the air purification of large brands after-sales service. Device. In the fierce market competition, this year, major appliance manufacturers are also stepping up research and development of new products. Midea, Philips, Haier, Panasonic, Hisense and Electrolux have released new air purifier products. Then, in the face of the market's dazzling array of air purification products, in addition to price considerations, consumers should pay attention to the following aspects when choosing. First of all, judge whether there is formaldehyde pollution in your own room. If there is, then it is recommended to buy a strong ability to remove formaldehyde. Nowadays, there are many new technologies for air purifiers on the market. The dust particles are: activated carbon adsorption, electrostatic dust collection. HEPA efficient filtration. For bacterial viruses: active oxygen, low temperature asymmetric plasma air purification. For the reaction of formaldehyde benzene, there are: molecular complexation and photocatalytic catalytic decomposition. In addition, negative oxygen ions are specifically for second-hand smoke, consumers should consider their own when choosing. Second, think about whether additional features are needed, such as increasing humidity, increasing negative ions, and increasing oxygen. There is also the need to consider post-maintenance costs, regular replacement of filters and additives, replacement of consumable parts, and warranty services. What to focus on when buying Air output: A good air purifier must have a high air exchange rate, that is, a large air volume. It is expressed in (m3/h) in the product manual. The larger the value, the better. Purification efficiency: Select products with high purification efficiency, specifically the removal rate of solid particles, the removal rate of volatile organic compounds, and the removal rate of formaldehyde. These three indicators are usually expressed as a percentage, and the larger the value, the better. Filter: The mainstream air purifier has 3~4 layers of filters, and there are 5~6 layers on the tall ones. Each layer of filters is for different pollutants. For example, the pre-filter can absorb small dust particles and hair; Deodorizing filter refers to activated carbon filter, which can remove sweat odor, pet smell and other odor; formaldehyde removal filter is specifically for formaldehyde; HEPA dust filter is used to remove dust, pollen, germs, second-hand smoke, dust, etc. Tiny particles. Air purifier to be maintained The air purifier should be maintained regularly. Consumers are advised to carefully read the instructions for the air purifier used and clean the filter as required. In general, the pre-filter can effectively remove large dust. It is recommended to clean it once a month. First use a vacuum cleaner to remove the surface dust and then wash it. The allergen filter can filter out pollen from the air and pets. Allergens such as hair are recommended to be cleaned once a month, not washed, and can be beaten and dusted; activated carbon filters are generally used to remove odors from the air and cannot be washed. It is recommended to replace them once every six months. The insiders suggest that when choosing an air purifier, it is not cheap, the key depends on the quality of the product and after-sales service. At the same time, consumers should choose the right function when purchasing, rather than the more functions, the better.
