While HEPA filters make them effective against a wide range of pollutants like mold spores, pollen and pet dander, these air purifiers are not capable of trapping much smaller odor-bearing particles, some of which can measure less than 0.001 microns in diameter. "To remove odors or gases, ...
How Do Air Purifiers Work? Most air purifiers sanitize the air by pulling indoor air through a filter. The filter then traps dust and other airborne particles before releasing clean air back into the room. Filters are usually made of fiberglass, paper, mesh, carbon, foam, or aluminum. Accord...
However, not all air purifiers rely on the same technology, nor do they use the same type of filtration system. Some machines may be able to capture tiny particles such as pollen, pet dander, or dust mites, while others may not. Frequently Asked Questions What do air purifiers remove from...
A fan is another critical component of any air purifier. It helps the purifier suck in the polluted air and push out the filtered air. Air purifiers have different fan speeds to control how quickly you want the surrounding air to get filtered. But the faster you run the fan, the more no...
In addition to removing irritating airborne particulates, air purifiers can alsomake the air feel fresher and cooler. These devices remove unpleasant odors by filtering out pet dander, removing odor-causing particles, and eliminating mold and mildew elements. ...
Air purifiers that use HEPA filtration may have higher power consumption for the same reason (which means they're more expensive to run for long periods and noisier than rival technologies, such as photocatalysis, that work in different ways). A HEPA filter will also need cleaning or replacing...
In air purifiers that work using a method called photocatalysis, light energy kick-starts a process that zaps all kinds of nasty air pollutants and turns them into harmless substances instead. For people who suffer from asthma and allergies, light-powered air purifiers like these are another ...
