Air purifiers work to remove bacteria and other contaminants from the air we breathe. They get rid of possible allergens, as well as cigarette or tobacco smoke and asthma-causing microorganisms. Air purifiers clean the air using filters, through various processes like carbon filtering and UV air purification.
Air purifiers come in all shapes and sizes. There are those manufactured for commercial use and those especially made for the home. Commercial air purifiers are larger and bulkier, meant to filter enough air for office space and even buildings. These kinds of air purifiers serve large groups of people, providing enough clean air for the entire workplace. Meanwhile, home air cleaners are more compact and can be placed anywhere inside a house.
