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.

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.

We’ve rounded up some of the best cooling air purifiers you can buy online, based on ease of use, effectiveness and features.

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.
