All of these models emit less than 70 decibels of sound, even on their high settings. We rounded up the following highly rated air purifiers we recommended in our previous coverage. Since air purifiers may run constantly in your home, we looked for the quietest highly rated models, specifically ones that are softer than 70 decibels at the highest setting and that have lower settings closer to the sound of a low whisper, which the CDC says is about 30 decibels.
“Air purifier noise should easily fade into background sounds and not be noticed,” said Szkiler.Īccording to the CDC, sound above 70 decibels can annoy you or damage your hearing over time.
If an air purifier makes a sound that’s unsettling to you, it might be time for a different model, regardless of the decibel level. “Think of a mosquito, they aren't loud but you soon notice when you have one in the room and the sound they make.” “There’s nothing more annoying than a constant disturbing noise when trying to drift off to enjoy a good night's rest,” said Szkiler. Where you put the purifier also matters - any sounds it makes may reflect off other surfaces and echo back, creating even more noise.ĭecibel level was the main criteria we used in choosing products, but there’s more to noise than just volume. But a good purifier should “blend” the sound of the fan and motor, eliminating noises like chopping through the air or an accompanying, annoying pitch, Szkiler said. Most air purifiers use fans to force air through a filter, which subsequently removes pollutants from that air.

While air purifiers may not strike you as the loudest appliance, their internal fans can produce a fair bit of noise, according to Poppy Szkiler, CEO and founder of Quiet Mark, a UK-based, independent accreditation firm that collaborates with the Noise Abatement Society to identify the quietest products.
