Research published in the Journal of Environmental Health showed PCO could reduce certain viral strains in air by over 89% within a short time frame (Takahashi et al., 2022).
These technologies highlight the multifaceted approaches air purifiers use to enhance air quality and reduce the spread of airborne viruses.
Why Is HEPA Filtration Essential for Virus Removal?
HEPA filtration is essential for virus removal because it effectively captures airborne particles, including viruses, from the air. HEPA stands for High-Efficiency Particulate Air, and HEPA filters can trap at least 99.97% of particles that are 0.3 micrometers in diameter.
The U.S. Environmental Protection Agency (EPA) defines HEPA filters as air filters that meet specific standards for particle removal. According to the EPA, these filters are effective against particles including allergens, dust, and harmful microorganisms.
HEPA filters work through a combination of mechanisms: interception, inertial impaction, and diffusion. Interception occurs when particles follow the air stream and come into contact with fibers in the filter. Inertial impaction happens when larger particles cannot easily follow the air stream and collide with the fibers. Diffusion affects smaller particles, as they move erratically and are likely to be caught by the fibers due to this unpredictable movement.
In technical contexts, “viruses” refer to microscopic infectious agents that can only replicate within living host cells. These agents are usually much smaller than bacteria, usually ranging from 0.02 to 0.3 micrometers, making their removal more challenging. HEPA filters can still capture these particles effectively due to their ability to trap smaller sizes when in motion.
Specific conditions enhancing the performance of HEPA filters include proper air circulation and maintenance. For instance, placing a HEPA filter air purifier in a room with minimal obstructions will improve airflow. Regularly changing or cleaning the HEPA filter as recommended by the manufacturer will maintain its efficiency. Scenarios such as using a HEPA filter in healthcare settings, especially during flu seasons or pandemics, significantly contribute to reducing the spread of respiratory viruses by continuously filtering the air.
