Air purifiers come in a wide array of designs, manufacturers, and models. Some use ultraviolet light to kill pathogens. Some use an electrostatic charge to trap contaminants. They come in small portable versions as well as those designed to integrate with HVAC systems and improve air quality for the whole home.
One of the most common questions about air purifiers is how much of the time they should be used. Do you need to run your air purifier all the time?
