According to the EPA, indoor air tends to be two to five times more polluted than outdoor air, since there is less ventilation and recirculation of air. This is where an air purifier can come in, to ensure that you can breathe easy, despite external stressors. How Does an Air Purifier Work? An air purifier works by drawing air into its chamber and running it through a filter that captures germs, dust, mites, pollen and other potentially harmful particles from the airstream. The air purifier will then return the clean air back into your home. These days, the best air purifiers can also help to absorb or filter out odors, say, from cooking or smoke. Some air purifiers are also equipped with heating and cooling settings, to function as a standup fan or heater when the temperatures change.
