Manufacturers typically list how much square footage a purifier is designed to cover. You might see multiple areas listed, say one for the coverage provided in one hour and another for the coverage provided in five hours. Our experts recommend using the lower number since you’ll likely want a device that delivers quick purification. Keep in mind that even the largest model only has a coverage area of 500 feet. So if you’re looking to clear the air in a very large space, check out our winners with coverage areas in the 800 to 1,300 square feet range.
