The last couple of years have been really bad for air quality, no matter where you live. From everyday pollutants to wildfire smoke and a once-in-a-lifetime airborne plague, there are a lot of very good reasons to be worried about the air quality both inside and outside your home. The best air purifiers are a great way to filter out allergies, dust, and other airborne particles from the air and stop them from adversely affecting you and your family.
Most recently, the massive West Coast wildfires have sent a smoky haze all the way from Seattle to New York City. In Manhattan, thousands of miles away from the forest fires, the air quality index reached dangerously high levels of 170. Across the country, the hazy skies reminded Americans just how dangerous poor air quality can be. And then there’s the deadly coronavirus, which is still disrupting lives in so many ways.
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 air purifiers are becoming an ever-present appliance. The best air purifiers can purify the air inside your home, which can actually be more polluted than the air outside, according to the U.S. Environmental Protection Agency.
Nowadays, you certainly don’t have to be a germaphobe to be afraid of the air you breathe. For this reason, we’ve put together a list of the best air purifiers to keep the air in your home breathable and safe for all.
Do Air Purifiers Work?
The first and most obvious question is do air purifiers actually work? 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. Of course, you get what you pay for.
Air purifiers work by pulling air through a series of filters that eliminate indoor pollutants and odors, leaving healthy, clean particles behind. Can air purifiers help you achieve cleaner air in your home? Yes, but the process is more complicated than simply switching on an air purifier 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 and filter styles to choose from, 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. According to the EPA, these filters are rated to filter out particles 0.3 microns in size and larger, which in theory includes airborne coronavirus droplets and many types of common pollutants. Thus, they are extremely effective at purifying the air inside your home or workplace.
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. By choosing a HEPA filter for 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:

Do Air Purifiers Help With COVID-19?
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. COVID-19 particles are usually just 0.1 microns in size; however, they are usually attached to droplets or orther particles that are 0.3 microns in size or larger. Advanced filters, such as HEPA filters or N95 masks, are capable of filtering out particles 0.3 microns in size and larger, so in theory they should have no problem removing most coronavirus particles 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 kill viruses instead of catching them like HEPA filters. Combining an air purifier with a UV light or ionizer may be the most effective way to deal with COVID.
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. Getting vaccinated, wearing a mask, washing 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.
