With summer heating up, and the pandemic on round three (or four? We’ve lost count), a device that can kill germs and cool down a stuffy room is ideal for anyone without an air conditioner. But even if you’ve got AC, these cooling air purifiers are a welcome bonus, circulating clean air throughout the house and even showing you ratings and analyses of indoor air quality as it goes. Here’s what to know about about these amazing machines.
How Do Cooling Air Purifiers Work?
The best cooling air purifiers do double duty as both a cooling fan and air filter. Here’s what to keep in mind when shopping for the best cooling air purifier for your space.
Air Purification: When you think of pollution, the first thought is often from the outdoors. But appliances inside your house produce gasses that can be harmful in large quantities, as well as pollen produced from household plants, and germs spread from person to person. These devices will often identify pollutants, and either knock them out of the air or trap them in the filter.
Sensor: A sensor is where it all starts. This is the central brain of the device, informing it when levels of no2, VOC, co2, or indoor air quality gets to levels where it needs to flip on. Whether it’s built into the unit or remotely set up, the sensor is what you’ll be relying on when you’re not controlling this manually.
Fan: You’ll want the fan to be powerful based on the size of your room and house, but consider noise levels as well. If you’re purchasing this for sleep or to cool down a baking hot room on a summer night, a loud fan may be counterintuitive.
Filter: This is what’s going to be at the center of capturing nasty dust particles and allergens in the air, so make sure it’s up to the task. A HEPA air filter is ideal for trapping near 100% of pollutants in your home’s air, often as small as 0.3 microns. That’ll knock out things like mold spores, pollen, and especially pet hair.
Extras: Being compatible with Alexa or an AI home software is a nice perk for easier control, as well as hooking up to your house thermostat if possible.
What Are the Best Cooling Air Purifiers?
We’ve rounded up some of the best cooling air purifiers you can buy online, based on ease of use, effectiveness and features.
1. Dyson Pure Hot + Cool Air Purifier
Dyson Pure has the ability to not only cool down a room, but also heat it up, as well as purifying the air all around your space. Think of it as a 3-in-1 device.
This expertly-designed fan first senses pollutants in your home, captures them, and projects fresh air back out.
The LCD screen is especially detailed here and was among our favorite features, showing you the status of the filter as well as what it’s doing at each step. A handy remote control lets you control settings with the touch of a button.
The bladeless fan, meantime rotates to project cool air around the room, instantly cooling it down without distracting you with buzzing or noise.
2. Sensibo Pure Smart WiFi Air Purifier
Sensibo’s cooling air purifier is quick to set up and get going right out of the box, and is constantly scanning to keep the air clean and cool.
The device’s sensor calculates indoor air quality 24/7, turning off and on as needed, removing small particles along the way. The triple-layered HEPA and carbon filters do a nice job of catching nasty stuff in the air, and Turbo Mode kicks it into high gear, even when you’re not at home (using your phone’s GeoLocation).
WiFi connects up easily and it’s compatible with Apple HomeKit, Google Home, Amazon Alexa, and mobile iOS & Android apps. Plus you can integrate your existing AC setup and boost purifications significantly too.
3. Westinghouse Bladeless Tower Fan
This sleek bladeless beast removes and kills harmful particles from the air, including bacteria, viruses and mold, allowing you to breathe easier. The pre-filter and HEPA filter go even further, catching things like pet hair and dust, while sterilizing everything with UV light.
At 32 inches tall and only ten pounds, this cooling air purifier is easy to carry around between rooms, and the small remote lets you control its nine speeds from the couch. You can also angle it up to 45 degrees, to make sure you’re getting the best breeze. It’s also nicely quiet, at below 55db.
4. ULTTY Bladeless Tower Fan Air Purifier
At just a little over eight pounds, this cooling air purifier works well for a small bedroom or child’s room, even more so since it’s bladeless and safe for kids (and pets).
The airflow is smooth and covers about 320 square feet, with minimal noise and a 90-degree oscillation. It’s also particularly easy for anyone to operate, either by the LED touchscreen or included remote.
5. Lasko Products Oscillating Tower Fan
If the name Lasko stands out in your memory, there’s a good chance your parents, grandparents, or even great-grandparents had one in their home. The company has been around since 1906, and has kept up with the times, integrating air purification into a tower-model fan.
This covers an entire room with a relatively small and tall footprint, and has three speeds that still run quietly even on high. The air purification is a bit different than the others – the fan constantly disperses negatively-charged ions, which bond with harmful positively charged ions like dust, bacteria and pollen, pulling them to the ground and out of the air.
