An air purifier is a device which removes contaminants from the air. These devices are commonly marketed as being beneficial to allergy sufferers and asthmatics, and at reducing or eliminating second-hand tobacco smoke. Commercial grade air purifiers are manufactured as either small stand-alone units or larger units that can be affixed to an air handler unit (AHU) or to an HVAC unit found in the medical, industrial, and commercial industries.

Famous quotes containing the word air:
“Ancient history has an air of antiquity. It should be more modern. It is written as if the specator should be thinking of the backside of the picture on the wall, or as if the author expected that the dead would be his readers, and wished to detail to them their own experience.”
—Henry David Thoreau (1817–1862)
