How Do Air Purifiers Work?

Today’s air purifiers consist of a fan (sometimes more than one) and filters. An air purifier works to separate the pollutants by drawing in the room’s air through filters. In most cases, this is called a passive air purifier. Meanwhile, active air purifiers uses ionization to clean the air in your spaces. Overall, passive air purifiers tend to be more effective, as they permanently remove particulates by trapping and collecting them in the filters (which will need regular cleaning to maintain peak efficiency).
