Best Air Purifiers of 2024

Our winning air purifier was a hit among even the pickiest air-purifier connoisseurs, tested in rooms with pets and allergens. This Levoit Air Purifier was easy to set up, taking just four minutes from start to finish with clear and straightforward directions.

This medium-sized model is a good fit for a large room, with solid construction and an easy-to-read digital display on top. It’s also quite simple to remove the filter from the bottom when it’s time to change it out. We found that the airflow felt great while using the air purifier, and it was never distractingly noisy. In fact, the quiet and sleep settings were super quiet.

If you enjoy multiple features on a household appliance, this model is for you. There are loads of features on the digital display, plus even more on the app, which is easy to install via a QR code. This model is voice-activated through Alexa, too. The app is easy to set up, and it’s quite user-friendly, allowing the user to set a timer and create a schedule. The machine has handles on both sides, so you can move from room to room, and it’s very lightweight considering all it can do.

Here’s a small and simple model that could be a perfect choice for someone looking to buy their first air purifier. If you’ve got a small space in mind — like a compact office or den, a baby’s room, or a hallway — this is a great option. Set-up took just two and a half minutes. With its minimalist design, this air purifier could fit into just about any aesthetic and into any space thanks to its lightweight stature.

The Levoit Air Purifier for Bedroom is extremely quiet. On the lowest setting, we could barely hear it. The highest setting was a little louder, but nothing that would be distracting. You won’t be distracted by features, either. This is a very basic model with just three different settings: low, medium, and high.

We were off and running with this model with its quick set-up and easy-to-understand digital display and buttons. We chose it as one of our top picks for its quiet setting because you can barely hear it at all. The max setting, however, is quite loud. It could be difficult to have a conversation or watch TV with it in the same room. However, there are plenty of other softer settings.

The Bissell air400 has several features, including a timer that you can set to 1, 4, or 8 hours of continuous use. It’s got a filter change indicator and a digital display that indicates low, medium, and high levels of air contamination. (We corroborated the Bissell air400’s findings with our own air quality testing device.) It also offers a night mode that automatically turns off the machine lights and displays as the room gets dark.

Large, dusty spaces are no match for the Aroeve Air Purifiers, which are rated to help clear the air in rooms up to 1,095 square feet. This device features a color changing display that indicates the air quality levels of any given room: blue for “good air quality,” yellow for “moderate air quality,” and red for “poor air quality.”

Though this machine is capable of filtering the air in large rooms, it doesn’t actually take up a lot of floor space itself. It’s sleek and would blend into most home decor, with a design that looks like a small white box that’s not dissimilar to an oversized game console.

You may know the Clorox name for the brand’s surface cleaning products — but they’re also pros at cleaning the air. The brand’s Large Room Air Purifier noticeably improved our test room’s air quality after just 30 minutes on the lowest setting. We found it to be super easy to get started with — just slide the HEPA filter into the bottom of the device, then flip it right side up and plug it in to get one step closer to clean air.

It has four fan speeds and an auto setting, and the rounded filter sucks in debris from 360 degrees around the device. It’s rated to clear rooms with an area of up to 1,500 square feet, yet still manages to be smaller and lighter than many of the air purifiers we’ve tried.
