What Is a HEPA Air Purifier and How Does It Function?

A HEPA air purifier is a device that uses a High Efficiency Particulate Air filter to remove 99.97% of particles from the air as small as 0.3 microns. This makes it effective for filtering allergens, dust, smoke, and other pollutants from indoor air.

The United States Environmental Protection Agency (EPA) defines HEPA filters as those that can trap particles that are 0.3 microns in diameter with high efficiency. These filters are crucial in enhancing air quality in homes and workplaces.

HEPA air purifiers function by drawing in air through their filter. The filter traps particles, preventing them from recirculating into the environment. This process helps improve indoor air quality significantly.

According to the World Health Organization (WHO), indoor air pollution is a major health risk. The WHO emphasizes the importance of maintaining clean indoor air, where HEPA filters play a vital role.

Common sources of indoor air pollution include tobacco smoke, mold, and dust mites. These pollutants can trigger asthma, allergies, and other respiratory issues.
