If you live in a small apartment like me, you may need to have a multifunctional air purifier for a practical reason: space. These compact, dual-purpose machines are useful if you are tight on square footage or don't want to shell out the money for two separate appliances. Or maybe you're aesthetically driven and want something that looks cool in your space rather than a clunky, large air purifier that can be an eyesore.
Regardless of the reason, these multiuse air purifiers look good, save space, and combine appliances into a single, energy-efficient device.

This Dreo offers 99.97 percent HEPA filtration and an air quality sensor. You can control it with a remote, the Dreo app, Google Home, and Amazon Alexa. Best of all, the fan and purifier can operate independently, in case you need just one or the other or want to extend the filter lifespan (replacements run around $40).
The 12-month warranty isn’t the greatest, but the device has been trouble-free for nearly two years in our long-term tests. If you're in the market for a fan and purifier in one, this model is definitely worth a look. —Kat Merck Smart app Yes (compatible with Alexa and Google Home) Remote Yes Ideal room size 100 square feet to achieve 4.5 air changes per hour Weight 17.8 pounds Noise on high 62 dB (if both air purifier and fan are on max settings) Filter Prefilter, HEPA Warranty 1-year limited Extra Features Doubles as a fan; air purifier and fan can work independently of each other Best Air Purifier That’s Also a Heater Blueair’s small-room model is a little under 2 feet tall and has built-in heating and cooling. Blueair’s app is easy to use, and I preferred it rather than the actual control panel.
The panel did not always illuminate when pressed, making the buttons difficult to use. The app also has more options, like controlling the oscillation speed and angle. Blueair uses both mechanical HEPA filtration and electrostatic technology to capture pollutants in the air.
Its CARB certification is listed as electronic, unlike HEPA-only air purifiers that are listed as mechanical. The ComfortPure 3-in-1 also has an air quality index indicator light that responds to the purifier's built-in sensor to measure particulate matter (PM) 2.5. The easy-to-miss sliver of light glows blue for excellent, green for good, yellow for moderate, orange for polluted, and red for very polluted.
