1. Choose the right purchase channel
When buying air purifiers, it is recommended to try to buy them in formal channels such as large shopping malls, electrical appliances stores, brand stores and mainstream e-commerce websites. Choose an air purifier according to your actual needs.
Air purifier brands, functions, performance, design, and prices are all very different and dazzling. Consumers are advised to purchase products according to their actual needs, not the more functions the better. For example, for consumers who need to protect against PM2.5, it is recommended to choose an air purifier with outstanding PM2.5 purification ability. Newly renovated homes can focus on air purifiers with outstanding ability to remove formaldehyde and toluene.
2. Filtration technology
The filtering technology of particulate pollutants is mainly HEPA filter. The quality of HEPA filter is uneven. Although some small brand filters have high filtration efficiency, they have large resistance, low energy efficiency ratio, and are easy to block and have a short life. , It is generally recommended to use a deep dust-holding HEPA filter with electrostatic electret. Electrostatic electret technology makes non-woven fibers have positive and negative charges, effectively capturing particulate matter in the air. Many HEPA filters claim to have electrostatic electret technology. However, due to technical reasons, the electret charge of many filters will decay rapidly in a short period of time, resulting in a decrease in filtration efficiency. It is recommended to choose a 3M [] electrostatic electret HEPA filter, which uses the same electrostatic electret technology as 3M masks to permanently ensure that the electret efficiency does not decay. High efficiency, low resistance and large dust holding capacity are the last word!
3. Pay attention to the applicable area or particulate clean air volume (CADR)
The strength of the air purifier's purification ability is mainly determined by the applicable area and the amount of particulate clean air (CADR: the rate of clean air provided), and the relationship between the two is: applicable area = CADR × 0.1. The purification ability of other pollutants should be combined with the applicable area.
4. Energy efficiency ratio and energy efficiency grade
Air purifiers are usually used continuously for a long time. As an important indicator to measure the purification capacity and power consumption of air purifiers, the energy efficiency ratio deserves everyone's attention. The higher the energy efficiency ratio and energy efficiency level, the more energy-efficient the air purifier is and the lower the cost of use.
5. Ozone release
As a strong oxidant, ozone has a certain purification ability, but it is harmful to the human body. The state has mandatory safety requirements for the amount of ozone released by air purifiers, which is limited to ≤5×10-6% (ozone has a fishy smell).
