Is the air purifier useful?

What are the advantages and disadvantages of air purifiers?

1. Air purifier for activated carbon technology:

Advantages: it can absorb the odor in the air

Disadvantages: It is impossible to decompose harmful substances such as formaldehyde and benzene through physical, chemical and biological reactions to achieve the purpose of purifying air. It needs to be replaced regularly and costs are incurred continuously.

2. Air purifier for HEPA technology:

Advantages: It is the abbreviation of high eifficency oarticle air filters. Chinese means high-efficiency filter. It is effective for filtering fine particles, dust, bacteria, viruses and other substances above 0.3 microns.

Disadvantages: easy to damage, can not be washed with water, must be replaced regularly to continue to use. Maintenance is expensive. The HEPA filter has a high density and must have a powerful exhaust fan to drive air through it, which is more power hungry. Only particles and odors of pollutants flowing through the air can be filtered.

3, UV technology air purifier:

Advantages: anti-virus, sterilization function, low cost of use.

Disadvantages: UV is easy to cause damage to the cornea, skin, etc. of the human eye, and can not coexist.

4. Air purifier for ozone technology:

Advantages: Low concentrations of ozone can kill a variety of pathogens, viruses, mycoplasmas and microorganisms that are pathogenic to humans and animals that remain in the air, water, or on the surface of objects.

Disadvantages: Excessive ozone is an invisible killer, which can cause human neurotoxicity, dizziness, headache, decreased vision, and memory loss. Can not coexist with humans. Can not adsorb solid particles.

5. Air purifier with negative ion technology:

Advantages: Negative ions are combined with soot and dust particles in the air to generate soot and dust particles with static electricity, which are attracted by the ground to cause sedimentation and purify.

Disadvantages: Can not eliminate harmful gases such as formaldehyde and benzene.

6. Air purifiers for photocatalyst technology:

Advantages: It has the functions of dust removal and sterilization, and is a widely used technology.

Disadvantages: It must be activated by ultraviolet light of a specific wavelength. The life of the product is very short, the effect is not obvious, the ultraviolet light is harmful to people, and it is not suitable for human and machine coexistence during purification.
