With coronavirus cases on the rise across the nation and many states and cities tightening restrictions, it’s more important than ever to stay home—and stay safe and healthy. Air purifiers not only make your space more comfortable as you spend more time at home, but some experts believe they can help prevent the spread of COVID-19 indoors.

While no air purifiers have been tested specifically with the virus, models with a high-efficiency particulate air (HEPA) filter are capable of capturing at least 99.97% of particles as small as 0.3 microns, which is smaller than the size of most airborne pathogens. This could be especially helpful if you’re living with someone who has contracted the virus.

But which air purifiers are best for protecting your home against COVID-19? Based on our experts’ rigorous testing, these are the five best air purifiers you can buy right now.

1. Winix 5500-2

The Winix 5500-2 is the best air purifier we’ve ever tested. It uses a true HEPA filter, carbon filter, and plasma for filtering, which are recommended by experts for filtering COVID-19 particles. It performed incredibly well in our smell tests, virtually eliminating any trace of cinnamon and smoke. While it’s not the most technologically advanced air purifier we tested, it has a number of useful functions like sleep mode, a timer, and a number of status lights. That combined with reasonable price is why it’s our favorite model.

2. Dyson Pure Hot + Cool Cryptomic HP06

The Dyson Pure Hot + Cool Cryptomic has been unavailable for the past few months, but it’s finally back in stock on the brand’s site. The Dyson model is so popular because it’s more than just an air purifier—it’s also a space heater and a cooling fan, making it the most versatile product on this list. That’s why we named it our favorite upgraded air purifier as it excelled in removing scents and smoke from the air thanks to its cryptomic panel that has holes small enough to help remove formaldehyde. Though it’s more expensive than other air purifiers on the lists, it’s great features, easy filter replacement, smart capabilities (it connects with Amazon Alexa or Siri), and generally attractive aesthetics makes it more than worth it.

3. LG PuriCare 360-Degree Air Purifier

If you’re looking for smart features, then the LG PuriCare is your best bet for an air purifier as it earned our best smart purifier badge. While pricey, it has high-tech features that allow you to see the concentrations of particulates, make the whole unit rotate, check the filter status, and more. You can monitor everything right on your phone with the SmartThinQ app, which is compatible with Alexa and Google Assistant. Aside from its incredible features and pretty aesthetic, it has a superior filtration system using an ultra-fine pre-filter, a true HEPA filter, and an absorbent filter.

4. Blueair Classic 205

The Blueair Classic 205 offers basic controls that can be activated via your phone—a.k.a. you can start cleaning your home’s air from anywhere. It uses a HEPA silent particle filter and was particularly good at filtering out cooking stenches. While we found it to be a bit noisy, it’s great for those who don’t want to deal with too many functions.

5. Bissell Air220

We found the Bissell Air220 to be one of the least intrusive air purifiers we tested—a.k.a. it’s small and quiet. It’s easy and intuitive to use with just a single power button and a fan speed dial with five fan speeds. To remove a variety of VOCs, the Air220 uses the recommended HEPA filter, a carbon filter, and a pre-filter. Although it wasn’t our winner, we still think it’s a great option.
