A lot of people think that they are safe from air pollution the moment they escape the outside world and step into their beloved home. That couldn’t be further from the truth. From pet dander and pollen to tobacco smoke and dust, there are different particles that can contaminate the air inside your home, which is bad news if you or your family members have allergies.
The good news is that you can remedy that issue by getting an air purifier, which captures tiny airborne particles and ensures the air you breathe in your home is clean. But don’t just pick any air purifier; there are different kinds of air purifiers. Some are designed for a small bedroom while others are built for a very large room.
In this guide, we have compiled our reviewed list of the best large room air purifiers currently out on the market, including products capable of covering a 400-square-foot room. The products are listed according to price, in ascending order, allowing you to quickly see which products are within your budget range.
Not all large room air purifiers will cost you more than $200. There are also great options that sell for less than that amount, with the Winix 5500-2 being one of the best. A unit with a certified high-efficiency particulate air (HEPA) filter, this unit captures 99.97 percent of airborne particles as small as 0.3 microns, including dust and pollen, with a coverage of up to 360 square feet.
Standing at just under 24 inches, the Winix 5500-2 is no taller than a regular-sized desk and is very easy to use out of the box. It’s got four fan speeds, with the unit automatically switching to the quietest setting when the sleep mode is activated. Additionally, the indicator lights dim when in sleep mode, transforming the machine into a discreet cleaning system that won’t disturb your sleep.
While not as rich in features as some of the higher-end products out there, this Winix air purifier can get the job done and is great for bedrooms and the kitchen – provided the room size is within the machine’s range. The filter is also easy to replace, with the indicator light signaling if the machine requires a new filter.
Headquartered in California, Levoit is one of the best brands when it comes to air purifiers, offering both large room and desktop air purifiers.

An air purifier with a four-stage filtration system, the Fellowes AeraMax 300 features the AeraSafe Antimicrobial Treatment, which provides additional defense against the growth of microorganisms like bacteria and fungi. With different fan speeds to choose from, this air purifier can be very quiet and powerful, though not at the same time, as the highest setting is not exactly discreet.
What’s great about this Fellowes offering is that the smart sensor has minimal issues picking up changes in the room’s air quality, which can’t be said for a lot of other air purifiers out there. When in auto mode, the fan speed automatically adjusts based on the room’s air quality. On the downside, the lights on the user interface are too bright and can be annoying, so make sure to cover them up before you go to sleep if the machine is in your bedroom.
