Do Air Purifiers Clean Viruses? An Expert's Perspective

When used correctly, air purifiers can be a great help in reducing pollutants, including viruses, in the home or in confined spaces. However, they are not enough to protect people from COVID-19 on their own. The best air purifiers, also known as “air purifiers”, can help remove dust, pollen, smoke and other irritants from the air. They can also go a long way in eliminating dangerous airborne germs and bacteria.

According to the Centers for Disease Control and Prevention (CDC), air purifiers “can help reduce airborne pollutants, including viruses, in a home or in confined spaces”. The Environmental Protection Agency (EPA) adds that air purifiers are useful “when additional ventilation with outside air is not possible (for example, when a window cannot be opened at home or at work).Few research studies have shown that High Efficiency Particulate Air (HEPA) filters can completely eliminate viruses from the air, but there are cases where they can help. Contagious viruses that cause respiratory diseases can be transmitted directly through the air or enclosed in respiratory droplets that are released when an infectious person coughs or sneezes. When viruses are inside droplets, droplet size in the air is larger and easier to remove with HEPA filters.

This is why a powerful and effective air purifier is essential for improving air quality in large rooms and even full apartments. But even if you live with a healthcare worker or someone sick with COVID-19, before you rush out to buy an air purifier, our experts say that simply opening your home windows to let in fresh air will help dilute indoor pollutants, including virus particles. In 2003, during the SARS outbreak, the Hong Kong Hospital Authority recommended that hospitals use portable air purifiers with HEPA filters to help reduce transmission to healthcare workers if isolation rooms were not available. The CDC also states that air purifiers “can help prevent virus particles from accumulating in the air in your home”.This EnviroKlenz air purifier harnesses the power of HEPA filters and UVC bulbs to provide germicidal irradiation and eliminate harmful bacteria from the air. Now the company is getting into the air purifier game with the introduction of AirSoap, which changes a traditional filter for a high-energy “electric wind” technology, which PhoneSoap says is more effective at cleaning the air.

Do-It-Yourself (DIY) air filters are indoor air filters that can be assembled from box fans and square HVAC (or oven) filters. Researchers discovered that HEPA filters added to an air purification system filtered aerosols loaded with the virus. The air purifier will also be compatible with Google Assistant and Amazon Alexa, and an energy-saving air quality monitor adjusts the fan speed to match the room's air quality. An air purifier not only targets harmful germs and bacteria, but it can also be used to help reduce odors in the house and to filter smoke. A good air purifier will greatly help purify the air in your space, which will help eliminate congestion, congestion and nasal irritation.

HEPA filters help eliminate these respiratory allergens from the air and improve indoor air quality. If you intend to filter smaller air particles, make sure that the HEPA filter has the ability to filter particles in micro and nano sizes.
