HEPA filter
Advantages
High efficiency filtration: It has extremely high filtration efficiency for particles of different particle sizes. According to different HEPA grades, H12 can filter more than 99.9% of 0.3 micron particles, and H13 can reach more than 99.97%, which can effectively intercept dust, pollen, smoke, bacteria, etc.
Stable accuracy: Throughout the service life, as long as the filter is not damaged, its filtration accuracy remains basically unchanged, and it can continuously and stably purify the air.
No secondary pollution: The simple physical filtration method will not release harmful substances into the air, which is safer and more environmentally friendly.
Disadvantages
Easy to clog: When there are more particles in the air, the filter is easy to be clogged, resulting in increased wind resistance, affecting the air volume and purification effect of the air purifier.
Limited service life: As the number of filtered particles increases, the filter needs to be replaced regularly, generally ranging from 3 to 12 months, and the replacement cost is relatively high.
Ineffective for gaseous pollutants: It mainly targets particulate matter, and has weak adsorption and decomposition capabilities for gaseous pollutants such as formaldehyde and benzene.
