Abstract
Indoor air is purified using a purifying solution in an arrangement capable of removing formaldehyde and other pollutants, such as, for example, particulates. The arrangement can prevent re-vaporization of volatile compounds and can generate air that has been humidified or dehumidified. In one approach, incoming air is contacted with the purifying solution in a packed bed.
Claims22
A method for purifying indoor air, the method comprising:
- contacting an incoming air stream from an indoor environment with a purifying solution to retain one or more gaseous, vapor or particulate pollutants in the purifying solution and produce an outgoing air stream, wherein the contact between the incoming air stream and the purifying solution is conducted by:
- directing the incoming air stream to a purifying solution reservoir and through the purifying solution held in the purifying solution reservoir, or
- directing the incoming air stream to and through a packed column, and directing purifying solution from the purifying solution reservoir to and through the packed column;
- cooling or maintaining the incoming air stream from the indoor environment, the purifying solution reservoir, the outgoing air stream or any combination thereof to or at a temperature at which the vapor pollutants are in a liquid phase;
- optionally directing the outgoing air stream through a filter for removing particulates;
- and
- releasing to the indoor environment a purified air exhaust, wherein the purified air exhaust is dehumidified or humidified.
