Air Purifiers

An air purifier is a device that removes pollutants from indoor air to improve indoor air quality. These devices are widely marketed as being beneficial for allergy sufferers and reducing tobacco smoke.There are two types of air purification technologies, active and passive. Active air purifiers release negatively charged ions into the air, causing pollutants to stick to surfaces, while passive air purifiers use air filters to remove pollutants. Several different processes with varying degrees of efficiency can be used to clean the air.
