Best Air Purifier in India
The Best Air Purifier in India is a device which removes contaminants from the air in a room to improve indoor air quality.
These devices are commonly marketed as being beneficial to allergy sufferers and asthmatics, and at reducing or eliminating second-hand tobacco smoke.
The commercially graded 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. Air purifiers may also be used in industry to remove
impurities from air before processing. Pressure swing adsorbers or other adsorption techniques are typically used for this.
Air purifiers may be rated on a variety of factors, including Clean Air Delivery Rate (which determines how well air has been purified);
efficient area coverage; air changes per hour; energy usage; and the cost of the replacement filters.
Two other important factors to consider are the length that the filters are expected to last (measured in months or years) and
the noise produced (measured in decibels) by the various settings that the purifier runs on. This information is available from most manufacturers.
