Air Sterilizer Quality Identification

air sterilizer is a device that uses physical, chemical or other methods to kill or remove pathogenic microorganisms in the air to achieve disinfection and purification purposes.
In addition to killing bacteria, viruses, molds, spores and other so-called sterilizations, some models can also remove formaldehyde, phenol and other organic polluting gases in indoor air, and can also kill or filter pollen and other allergens. At the same time, it can effectively remove the smoke and smell produced by smoking, bad smells in the bathroom, and human body odor.

1. Unsuitable use environment The disinfection effect of
air disinfection machine is mainly affected by the use environment. If the room used is too crowded, or there are large areas of obstructions, such as obstacles, walls, etc., the disinfection effect of the air disinfection machine will be limited. In addition, in an environment with too high air humidity, its disinfection effect will also be greatly affected.
2. Quality issues with the sterilizer itself
The quality of air sterilizers on the market varies. Some low-quality air sterilizers use unsafe materials and are prone to secondary pollution. At the same time, there may also be problems in aspects such as air supply volume and holding time, resulting in unsatisfactory disinfection results.

For example, when the disinfection machine is running, if there are people walking back and forth in the room or opening doors and windows, the disinfection effect of the disinfection machine will be affected. In addition, if the air disinfection machine is used incorrectly, the disinfection effect may also be affected.
