The main function of air cleaner for home is to remove formaldehyde (HCHO) released from furnishings, boards, paints, paints, chemical fiber carpets, wall coverings, wallpapers and other decoration materials. Formaldehyde in indoor air is extremely harmful to people. Formaldehyde can induce various allergic diseases, such as allergic rhinitis, allergic skin diseases, and allergic asthma. For the elderly, pregnant women and children with weak resistance, formaldehyde may also cause blood diseases. International authoritative institutions have listed formaldehyde as a class of carcinogens. Under normal circumstances, the release period of formaldehyde is three to fifteen years.

Most air cleaner for home use adsorption to remove formaldehyde in the indoor air. With the fan of the purifier (the main source of noise from the purifier), the air purification speed can be forced to speed up. The key technology of the household air purifier is the filter. , The adsorption capacity of the filter directly determines the space that can be effectively purified per hour (CADR). Since air cleaner for home are mostly used indoors, when choosing, they should be turned on and run normally for three to five minutes, and listen to the actual air purifier. Whether the noise performance during use is within the range that you can tolerate.

Ordinary air cleaner for home generally use activated carbon coconut shell filters. Manufacturers will try their best to increase the coverage area of ??activated carbon in the filter. The more the same size filter, the more activated carbon and other substances, the better the purification effect of the air purifier. To choose an air purifier, you need to estimate the area of ??the purification space in advance, such as an area of ??50 to 90 square meters. You can choose an air purifier with a CADR value of 800 cubic meters per hour.

Another measure of air cleaner for home is the cumulative purification capacity (CCM). CCM is divided into four levels (P1, P2, P3, P4). The higher the level, the longer the service life of the filter. There are also some long-life air purifier filters on the market, which contain a catalyst layer (decomposes the adsorbed formaldehyde into water and carbon dioxide). No matter how high the values ??of CADR and CCM are, cleaning and replacing the filters in time is to keep the room indoors. An important part of fresh and pleasant air.

In newly renovated or renovated houses, while using air cleaner for home, ventilation and circulation of the air should be strengthened, and some green plants can also be planted to absorb harmful substances such as formaldehyde. Indoor formaldehyde removal is not a one-day effort, and you must not rush it. It is recommended that air cleaner for home be used for a long time.
