9 Best Air Purifiers of 2023, According to Testing

We updated this guide in April 2023 to ensure all of our recommendations, tested and vetted by the Good Housekeeping Institute Home Improvement Lab, were in stock and correctly priced. We also added newly tested models from Dyson and Coway.

In recent years, air purifiers have evolved from a mostly niche product to a must-have health and wellness device in many homes, thanks to the steady rise in indoor air pollutants—everything from wildfire smoke to a pandemic-fueled uptick in households that own a pet. As with any consumer product, the surge in demand has brought more brands into the market, along with significant innovations.

“Improved filtration helps today’s air purifiers capture more contaminants from the air in your home,” says Carolyn Forté, executive director of the Good Housekeeping Institute's Home Care and Cleaning Lab. But some purifiers are better than others, according to our latest round of testing, which took our total number of reviewed models up to 45. Testing takes place in labs at the Institute, as well as in homes of consumer testers, which allows us to evaluate the devices in real-world conditions.

While an air purifier's ability to remove contaminants is the most important criteria, our experts also consider such factors as ease of use, maintenance and operating costs, the same way we do with other air treatment equipment, like humidifiers, portable air conditioners and dehumidifiers.

Keep in mind that an air purifier on its own can’t give your home perfect indoor air quality (IAQ). But when combined with IAQ best practices — like regular vacuuming and controlling indoor humidity levels throughout the year — the following top-rated air purifiers can help make your home a healthier place.
