Most of us only know air purifiers as those tiny stand-alone devices which can be kept inside a room to clear the atmosphere inside of all impurities that may cause allergies later on. Seldom does anyone realize that many places that we frequent make use of such devices. Not all air purifiers are as small as the domestic machines that we can read about online in air purifier reviews and articles.

Air purifiers are used in large numbers in institutions such as government buildings, hospitals and even industries. They not only protect against allergens but also remove dangerous air particles such as gases and other items which may cause health complications such as allergic reactions.

The large scale air purifiers that are used in such places are not all that different from the tiny home models. They only take in air in larger quantities and filter them using larger and more active filters. The end result is still the same as it is with the tiny HEPA air purifiers available in the market commercially.
