Air purifiers can reduce the formaldehyde content in indoor spaces to a certain extent, but they cannot completely remove formaldehyde.
Air purifiers use the principles of filtration and adsorption to adsorb, decompose and transform odors in the air to achieve the purpose of purifying the air. The main purification objects of air purifiers include PM2.5, dust, Pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc.
Air purifiers are divided into two types: active and passive. Active purifiers refer to various products that continuously release formaldehyde into the air to achieve the effect of removing formaldehyde. When using this type of purifier, you must pay attention to the quality and decomposition efficiency of the product it releases, and whether it will cause secondary pollution of indoor air.
Passive air purifiers, most of which are filter purifiers, inhale indoor air and then adsorb formaldehyde molecules and PM2.5 and other particulate matter through an activated carbon filter to purify indoor air. quality purpose.
Precautions for using the air purifier
1. When using the air purifier, you must first pay attention to the placement position and place it in a relatively central place indoors. This position is harmful to the air. The circulation efficiency is also the highest. If it is placed in a corner, the purification range will be reduced and it will not be even enough. At the same time, it should not be close to the wall or too close to the furniture. Keep a distance of 20 centimeters around to facilitate air circulation.
2. The air purifier needs to be used for a long time to achieve a healthy standard, just like the refrigerator. Therefore, when using it, you must know that it will not be effective in a short time. It needs to be turned on for a long time. . You can adjust its gear. For example, you can use the large wind speed for the first half hour after turning on the machine to quickly filter the air, and then turn it to the small wind speed or set it in sleep mode to turn on the purification function to prevent excessive noise. Great impact on rest.
