The last couple of years have been bad for air quality, no matter where you live. On the west coast, 2020’s fires caused many Americans to realize just how dangerous poor air quality can be, which remains true even when forest fires aren’t pumping out dangerous smoke. And then there was coronavirus. All over the world, this airborne virus has been disrupting lives in so many ways it’s hard to know where to begin. Nowadays, you certainly don’t have to be a germaphobe to be afraid of the air you breathe. For this reason, we’re on the hunt for the best air purifiers.

Even under the best circumstances, the air inside your home can contain mold, bacteria, viruses, dander, smoke, volatile organic compounds (VOCs) and other potentially unpleasant pollutants. Many of these are either irritating to the lungs or result in unpleasant odors. Add in the age of airborne viral pandemics, and it’s easy to see why an air purifier is quickly becoming an ever-present appliance.


Do Air Purifiers Work?

The first and most obvious question is do air purifiers actually work? And a little frustratingly, the answer is not a simple yes or no. The best air purifiers can be very effective in filtering air pollutants, allergens and other toxic materials from the air, but as in many areas of life, you get what you pay for. 

Air purifiers work by pulling air through a series of filters that eliminate indoor air pollutants and odors, leaving only healthy, clean air particles behind. Can air purifiers help you achieve cleaner air in your home? Yes. But, the process is more complicated than simply buying an air purifier, switching it on and expecting it to do 100% of the work for you. Functionally, cleaning your home remains important, especially if you want to rid it of as many allergens and potentially harmful particles as you can. It’s possible for some particles to sit on surfaces without being moved through an air filter, which is why an air purifier as a component of a multi-action approach to cleaning is the best course of action.

Given that there are different air purifier designs to choose from, including different filter styles, it’s important to be as informed as possible in order to buy the one which is best suited to your needs. One easy-to-follow piece of advice — look for HEPA air filters.

What is a HEPA Filter?

High-efficiency particulate absorbing filters or high-efficiency particulate arrestance filters are more commonly known as HEPA filters. While the name may sound complicated, functionally these filters are simply an incredibly intricate layer of fibers, which remove 99.97% of particles from air when it is passed through the filer. By choosing a HEPA filter in your air purifier, you can be confident that it’s doing the job intended. This efficiency is preferable for reliable air cleaning and the removal of common particles, which can include:

  • Dust
  • Allergens
  • Mold
  • Smoke
  • Pollen
  • Dander
  • Viruses

Do Air Purifiers Help With Covid?

At this time, the biggest question you probably have is about whether an air purifier can help with, or completely remove, COVID from the air.

It is possible for air purifiers to remove the COVID virus from the air. However, given the size of the virus sits somewhere close to a HEPA filter’s lower end of filtering capability, it may take more than a single pass to remove it. This means you’ll need to run your purifier for longer to allow for the air to pass through more times. This will increase the chance of COVID being removed.

However, air-cleaning devices with built-in UV lights or ionizers don’t catch viruses like HEPA filters; they kill them instead. Combining an air purifier with a UV light or ionizer may be the most effective way to deal with COVID in the air.

So should you buy an air purifier or UV light to fight against COVID in your home? It may not be beneficial to you if this is the sole reason for doing so. Wearing a mask, cleaning your hands and socially distancing are sufficient and should remain a priority. But, if you have someone who has tested positive, needs to quarantine or falls in the highly susceptible category, having a COVID-removing air filter may serve some benefit, even if it is only in the form of reassurance.

To help out our readers, we searched for the best air purifiers online in 2021, with options starting at just $80. Keep reading to find the best products from brands like Dyson, Honeywell and Winix.


1. Dyson Pure Cool Link TP02 Wi-Fi Enabled Air Purifier
