Air purifiers can reduce indoor pollution, but they can't rely too much on it. Air purifiers can't replace cleaning, clean indoors regularly, avoid ventilation and open air ventilation, and reduce pollution sources is the fundamental to improve indoor air quality. The way.
How should consumers choose an air purifier?
According to the experience of Xiaobian, we should start from these aspects.
1. According to the applicable area of ​​the family
Air purifiers with different powers have different application areas. If the room is large, you should select an air purifier that purifies the air volume per unit time. For example, a 25-square-meter room is suitable for a purifier with a rated air volume of 200 cubic meters per hour, and a room with a rated air volume of 400 cubic meters per hour should be selected for a room of about 50 square meters. Every product will have this parameter, so be sure to look good before buying.
2. According to the purification function
Select the desired function based on the air environment of the home and the appropriate purification effect. The functions of the air purifier are mainly purification, sterilization, filtration, humidification, etc. Different products have multiple functions.
Sterilization: Suitable for indoors that are not ventilated for a long time. The main hazard: bacteria are the natural enemies of human beings, and are not mentioned here.
Humidification: Suitable for dry indoor environments. Advantages: Proper humidification stabilizes moisture, paper, textiles in wood, reduces fire risk and electrostatic forces, making the area comfortable and safe.
In addition to formaldehyde: suitable for newly renovated indoor environments. The main hazard: formaldehyde is a puree poison, can be combined with protein, inhalation of high concentrations of formaldehyde, there will be severe stimulation of the respiratory tract and edema, eye irritation, headache, bronchial asthma can also occur. Particulate particles with a particle size below 3.5 microns can be inhaled into the human bronchus and alveoli and deposited, causing or aggravating diseases of the respiratory system.
Soot: Suitable for spaces with smokers or dust; major hazards: smoke from tobacco combustion, producing more than 40 kinds of substances with carcinogenic effects. Smoking is one of the main causes of lung cancer.
3. According to the purification method
HEPA (High Efficiency Air Purification): HEPA high-density filter material is also one of the most advanced air filtration materials in the field of air purification. I recommend that consumers choose products with this technology when purchasing, which can filter well. Adsorption of pollutants above 0.3 microns, it has a strong purification ability for soot, inhalable particles, bacteria and viruses, and the addition of catalytically active carbon is better for the purification of odorous harmful gases.
4. Persistence of use
When you purchase this product, you should pay special attention to its service life. Although it is not required to be used forever, it should at least guarantee the most basic service life.
There are several suggestions for improving the indoor air quality. First of all, reduce the pollution source as much as possible. It is best not to use copiers, electrostatic precipitators, gas stoves indoors, as much as possible without using asbestos boards, etc., because ozone will be generated, respiratory tract And the lungs will be affected. Secondly, keep indoor ventilation, when the air quality is good, change the air more frequently, and during the morning and evening peaks with serious air pollution, open the window less. You can put some green plants indoors, which can not only absorb harmful gases, but also beautify the space. Smoking friends should try to choose outdoors or on the balcony to reduce the indoor pollution.
