Air purifiers are small household appliances used to purify indoor air, mainly to solve indoor air pollution problems caused by decoration or other reasons. Because the release of pollutants in indoor air is persistent and uncertain, the use of air purifiers to purify indoor air is an internationally recognized method to improve indoor air quality. Air purifiers can reduce indoor pollution, but they should not be overly dependent on them. Air purifiers cannot replace cleaning. Clean indoors regularly, avoid opening windows for ventilation during peak pollution periods, and reduce pollution sources is the fundamental way to improve indoor air quality.
How should consumers choose an air purifier?
1. Choose according to the room area
Air purifiers of different power have different applicable areas. If the room is larger, you should choose an air purifier with a larger air volume per unit time. Under normal circumstances, a room with 25 square meters is suitable for a purifier with a rated air volume of 200 cubic meters per hour, and a purifier with a rated air volume of 400 cubic meters per hour for a room of about 50 square meters. Every product will have this parameter, so be sure to look at it before buying.
2. Choose according to purification function requirements
Select the required functions according to the residential air environment and suitable purification effects. The functions of air purifiers are mainly sterilization and disinfection, air purification, smoke removal, etc. Different products have multiple functions.
Sterilization: suitable for long-term unventilated indoor environment.
In addition to formaldehyde, benzene, etc.: suitable for the indoor environment of newly decorated and newly purchased furniture. Formaldehyde is a protoplasmic poison and can be combined with protein. After inhaling high concentrations of formaldehyde, severe respiratory irritation and edema, eye irritation, headaches, and bronchial asthma may also occur. Particles with a particle size below 3.5 microns can be inhaled and deposited in human bronchial tubes and alveoli, causing or aggravating respiratory diseases.
Smoke and dust: suitable for smokers or dusty spaces. The smoke produced by the burning of tobacco produces about 40 kinds of substances with carcinogenic effects. Smoking is one of the main causes of lung cancer.
3. Choose according to the purification method
According to the selection of purification methods, purification methods are mainly divided into three categories: activated carbon adsorption, HEPA (High Efficiency Air Purification), and UV lamps.
4. Convenience of replacing the filter material
Before buying, you should also understand whether it is convenient to replace the filter material of the air purifier. Generally, only the primary filter of the air purifier needs to be replaced by yourself, and other parts generally need to be replaced or repaired by the repairer. This must be confirmed clearly before purchase.
5. The service life of the air purifier filter material
When purchasing this product, you must pay special attention to its service life, because the filter material with a short service life has limited purification effect. For example, some businesses will prepare several sets of filter materials when testing, use one set of filter materials when testing PM2.5, change one set of filter materials when testing formaldehyde, and another set of filter materials when testing benzene. This shows that the service life of the filter material is very short. After one item is tested, the effect will be greatly reduced if another item is tested. Therefore, this is a serious violation of business ethics cheating method used in the detection.
