How Does an Air Purifier Work to Remove Coronavirus from Indoor Air?
An air purifier works to remove coronavirus from indoor air by using a combination of filtration technologies. First, filters capture airborne particles, including viruses. High-Efficiency Particulate Air (HEPA) filters are common in many purifiers. They can trap at least 99.97% of particles that are 0.3 microns in diameter. This size includes many viruses, making HEPA filters effective.
Next, the air purifier pulls air from the room into its system. A fan inside the device facilitates this process. The air then passes through the HEPA filter, where particles are trapped. Some air purifiers also use activated carbon filters. These filters can remove odors and some harmful gases, complementing the HEPA filter.
Additionally, some air purifiers employ ultraviolet (UV) light. UV light can deactivate viruses, reducing their ability to infect. When air passes through the UV chamber, any remaining viruses can be rendered harmless.
Finally, the clean air is released back into the room. This cycle continues, improving air quality over time. Using an air purifier can significantly reduce the concentration of airborne coronavirus particles, contributing to a healthier indoor environment.
What Key Features Should You Look for in an Air Purifier for Coronavirus Protection?

HEPA Filter: A HEPA (High-Efficiency Particulate Air) filter efficiently captures 99.97% of particles as small as 0.3 microns. This includes the size of many airborne viruses like coronavirus. According to the CDC, using filters that meet HEPA standards helps reduce airborne viruses in indoor settings.
-
Activated Carbon Layers: Activated carbon filters absorb gases and odors, including volatile organic compounds (VOCs) and smoke. They work alongside HEPA filters to remove chemical pollutants. Research from the University of California indicates that these filters can significantly reduce airborne chemical agents.
-
UV-C Light Technology: UV-C light is effective in deactivating viruses. Air purifiers equipped with this technology use ultraviolet light to kill microorganisms in the air. A study published in the American Journal of Infection Control states that UV-C can reduce virus concentration exponentially.
-
High Clean Air Delivery Rate (CADR): CADR measures the purifier’s ability to remove smoke, dust, and pollen. A higher CADR indicates better performance. The American Lung Association recommends choosing purifiers with CADR ratings specific to the room’s size to ensure sufficient air filtration.
-
Coverage for Room Size: An air purifier must match the size of the room for optimal effectiveness. Manufacturers provide recommended room sizes based on the airflow rate. Properly sized units ensure adequate air exchanges per hour to dilute viral particles in the air.
-
Noise Level: Noise levels matter, especially for home use. Look for purifiers with multiple fan speeds to control noise output. Various consumer reports note that quieter models are preferable for bedrooms or study areas.

- High-Efficiency Particulate Air (HEPA) filters
- ULPA filters
- Activated carbon filters
- Photocatalytic oxidation (PCO) filters
- Electrostatic filters
While HEPA filters are the most commonly recommended due to their ability to capture small particles, there’s ongoing debate about the effectiveness of other filters like activated carbon and PCO in removing viruses. Different air purifiers utilize varying combinations of these technologies, impacting their overall effectiveness.
-
HEPA Filters:
HEPA filters are defined by their capability to capture at least 99.97% of particles that are 0.3 microns in diameter. This includes many viruses, allergens, and pollutants. A study published by the Journal of Aerosol Science (Sung et al., 2020) indicates that HEPA filters can effectively trap aerosolized coronavirus particles in the air. These filters are widely used in various settings, including hospitals and homes. -
ULPA Filters:
ULPA filters, or Ultra-Low Penetration Air filters, have an even higher efficiency than HEPA filters, capturing at least 99.999% of particles down to 0.1 microns. They are used in environments like clean rooms and laboratories. A 2020 review by the Environmental Protection Agency highlighted that ULPA filters can significantly reduce airborne pathogens, including viruses, due to their stringent filtration capabilities. -
Activated Carbon Filters:
Activated carbon filters focus on removing gases, odors, and some volatile organic compounds from the air. They work by adsorbing these substances onto their porous surface. While they are effective for chemical pollutants, their ability to remove viruses is debated. A study published in Environmental Science & Technology (Shu et al., 2021) stated that activated carbon filters do not directly inactivate viruses but can contribute to overall indoor air quality through chemical absorption. -
Photocatalytic Oxidation (PCO) Filters:
PCO filters use a titanium dioxide catalyst activated by UV light to break down pollutants and pathogens. Research indicates these filters can reduce viruses in indoor environments. A study by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE, 2020) noted that PCO systems potentially inactivate airborne viruses, but the effectiveness can vary based on exposure time and UV intensity. -
Electrostatic Filters:
Electrostatic filters work by using an electric charge to attract and trap particles in the air. They can effectively capture dust, smoke, and pollen. However, their efficacy against viruses is less studied. A report from the National Institute for Occupational Safety and Health (NIOSH, 2021) indicated that while these filters may capture larger airborne particles, more research is needed to assess their effectiveness in virus removal specifically.
How Do Different Air Purifiers Compare in Efficiency of Virus Removal?
Different air purifiers vary in their efficiency for virus removal based on their technology and specifications. Below is a comparison of several common types of air purifiers and their effectiveness in removing viruses:

How Can You Optimize Your Air Purifier’s Effectiveness Against Coronavirus?
To optimize your air purifier’s effectiveness against coronavirus, choose a HEPA filter, maintain proper airflow, ensure adequate placement, and regularly replace filters.
A HEPA filter captures small particles, including viruses. HEPA stands for High-Efficiency Particulate Air. These filters trap at least 99.97% of particles as small as 0.3 microns. According to a study by Chen et al. (2020), HEPA filters significantly reduce airborne viral transmission.
Proper airflow is essential. Ensure the air purifier has enough airflow to circulate the entire room’s air a few times per hour. Look for purifiers with a Clean Air Delivery Rate (CADR) rating appropriate for your room size. The higher the CADR, the faster it cleans the air.
Placement of the air purifier matters. Place it in high-traffic areas, such as living rooms or offices. Do not obstruct airflow by placing it near walls, furniture, or curtains. For optimal results, position it at least several feet away from walls and other objects.
Regular filter replacement is vital. Follow manufacturer guidelines on how often to replace HEPA filters. Most suggest every 6 to 12 months, but it depends on usage. Filters that are clogged become less effective and can even recirculate germs back into the air.
Additionally, consider using an air purifier with ultraviolet (UV) light. Research by Cadnum et al. (2020) found that UV light can inactivate viruses in the air, adding another layer of protection.
Finally, keep windows and doors closed when using your air purifier. This prevents outdoor pollutants from entering and gives your purifier higher efficiency in filtering indoor air.
