LEVOIT Air Purifiers 300S

The LEVOIT Core 300S was one of the quietest air purifiers we tested, measuring in at just over 20 decibels on its lowest fan setting. That’s quieter than a low-speed ceiling fan or a refrigerator hum. It’s also just as capable at cleaning the air as any other purifier on this list.

The Core 300S is a great choice for people who don’t want to be distracted by their purifier while they work or sleep. It offers all the standard settings you’d expect from an air purifier: high and low fan speeds, settings for night, day, and auto modes, and several options for the type of filter.

What truly sets this purifier apart is the addition of Wi-Fi connectivity. Using the free VeSync app, you can check room temperature and air quality in real time, as well as set schedules and control the settings on your purifier from anywhere in your home.
