7 Best Air Purifiers for COVID-19 - Reviewed and Rated 2021

Last Updated on March 9, 2021

While we continue to learn more about COVID, many researchers believe one of the significant causes of infection is through airborne particles. Germs travel through the air when we sneeze, cough, or even when we talk. Because research is still in the early phases, scientists have not yet proven that air purifiers can prevent or reduce the spread of COVID.

However, because air purifiers remove airborne particles, bacteria, and viruses from the environment, they may help reduce the risk of COVID-19 transmission. Based on its outstanding filtration and purifying features, we’ve picked the best air purifier for COVID based on current understanding.

How to Choose the Best Air Purifier for COVID?

There are several factors to consider when purchasing an air purifier. While they are features you may desire as standard, additional options can cater to your individual preferences.

Purification Process 

While all air purifiers clean the air, they can use different systems and processes. You may prefer the ability to check a filter is working by looking at the amount of dust and dirt it traps. However, a UV light purifier is cleaner as it kills germs while they are in the air.

You can also opt for a combination of both processes in one unit. Your preferred system comes down to individual preference, but both are highly-effective air purifying methods.

Air Purifier Size

To effectively clean the air, you need to find the right-sized unit for your space. If you have a large room at home, or the purifier is for office use, a larger unit is more suitable. For portability or use in multiple places, a more compact air purifier may be more desirable.

Air Purifier Noise Level

We found that nearly every air purifier emits a moderate amount of operating noise. Most of the time, some sound won’t be an issue, but if you really must have a near-silent model, then you’ll want to choose carefully.

Noise levels are particularly important if you use your air purifier overnight while you sleep or run the unit in a room where you watch television or listen to music.

Air Purifier Convenience

We enjoyed the touch screen control panels on the air purifying units, and Bluetooth control took convenience to the next level. Because some air purifiers have auto adjust fans that react to varying pollution levels in your home, you may not even have to change the fan speed throughout the day.

While air purifiers are easy to use, purchasing a model that connects to your phone or tablet, or responds to voice commands on a smart system removes any unnecessary hassle.

Final Verdict

The exciting range of modern air purifiers’ features may reduce the risk of infection from bacteria and viruses. While we await the scientific confirmation, a high-quality air purifier may reduce the likelihood of contracting a COVID infection by minimizing pollutants in the air for optimal immune function.

With user-friendly features such as a touch screen display and Blueair app, combined with effective HEPA filters and a high-purification capacity, we couldn’t fault our pick for the best air purifier for COVID available. 

If you’re ready to invest in the best air purifier on the market today, choose the Blueair HealthProtect 7470i Smart Air Purifier.
