How to choose an air purifier
1, choose the one with large CADR value, and the bigger the better.
The advantage of large air volume is simple: others can drive indoor air 1 hour to be relatively clean, and you can achieve it in 10 minutes, and breathe less unclean air for 50 minutes. Therefore, the greater the CADR value of air purifier per hour, the better, which is very important in China where air pollution is serious.
2. HEPA membrane filtration and activated carbon filtration technology are selected.
HEPA membrane+activated carbon is an undisputed effective filtration technology, so you don't have to spend time studying technical terms when choosing them. New technologies such as static electricity are either immature or risk producing ozone. So, don't be fooled by filtration efficiency and buy expensive ones.
3, combined with the calculation of purified air volume, choose the machine and low consumables.
The basic structure of HEPA air purifier is filter screen+fan, which is simple in structure and can be used for several years by choosing famous brands. The so-called new technology, complex structure, advanced appearance, imported from abroad, etc. , bringing slightly higher filtering ability and unnecessary cost, which also increases the profit space of merchants. 600 yuan's big-name entry products and expensive products with the same air volume of 3,000 yuan are really five times worse in life and effect? It is recommended to consider the price of the machine and consumables, and choose the one with the highest cost performance and the lowest price in combination with the air volume and the size of the filter screen (dust capacity), and buy more sets for comprehensive protection.
4. Choose famous brands.
Because it is a bargain, we should choose famous brands, and the materials used are generally reliable, especially motors. At the same time, there will be good after-sales guarantee and normal product quality-don't expect too much in quality. Air purifiers are auxiliary transitional products (fresh air is the ultimate necessity), and all brands are stepping up their upgrading. It is unnecessary to expect to use them in 10 year.
Step 5 choose a low-noise one
Because it has to be opened every day, the lower the noise, the better. Moreover, noise is also an important index to measure the technical level and material quality of manufacturers. Due to lack of experience, Internet vendors often have their first-generation products here. However, if the standard air volume is too large and the air reaches the standard, the noise will definitely be significantly reduced.
6. According to the area of the room, choose an air purifier suitable for the air volume, with a small room corresponding to a small air volume and a large room corresponding to a large air volume.

Matters needing attention in purchasing air purifier
1. To buy an air purifier, you must first have a real filtering effect.
2. Buy the CADR value calculated according to the actual use area of your home.
3. Pay attention to the safety performance of the air purifier. At present, the standard safety protection commonly used in air purifiers includes anti-dumping, anti-electric shock and child lock. If the general air purifier doesn't even have these basic safety functions, there are still some safety hazards when the product is used.
4. The problem of use cost is easily overlooked by consumers, because the filter material of air purifier belongs to disposable material. In addition to the general primary filter can be washed with water, the conventional HEPA and activated carbon filters need to be replaced regularly. Many people seem to buy a machine very cheaply, but the filter that is not used well may be replaced once a month, so your use cost will be higher. So don't be greedy for a moment's cheap, and choose cheap products, which is irresponsible for the health of yourself and your family!

Matters needing attention in the use of air purifier
1. During normal use, it is recommended to keep doors and windows closed as much as possible to avoid the decrease of purification effect caused by a large number of interactive circulation of indoor and outdoor air. After long-term use, pay attention to regular ventilation.
2. If it is used to purify indoor gaseous pollutants such as formaldehyde, the actual pollution level should be roughly grasped. Under the condition of serious exceeding the standard (generally exceeding the standard by more than 5 times), effective ventilation should be carried out before use.
3. At the initial stage of operation of the air purifier, it is recommended to run at the maximum air volume for at least 30 minutes before switching to other gears to achieve the effect of quickly purifying the air.
4. Replace or clean the filter screen regularly to ensure the purification effect of the air purifier and avoid the secondary discharge of pollutants adsorbed by the invalid filter screen.
5. Before the air purifier that has not been used for a long time is turned on again, check the cleanliness of its inner wall and the state of the filter screen, do a good job of cleaning, and replace the filter screen if necessary.
