Filtration and air cleaning are methods for improving indoor air quality by removing pollutants and contaminants from the air, thus lowering the pollutant concentration indoors.

There are a variety of different technologies that can be used for filtration and air cleaning. The selection of appropriate technology for a given application will depend on the types of contaminants that need to be removed and the size of the space.

Filtration

Filtration is a process that physically removes particles from the air by passing the air through a filter medium.

Air cleaning

Air cleaning encompasses a broader range of technologies and methods that remove or neutralize contaminants from the air, including both particulate matter and gaseous pollutants.

Mechanism:

Physical processes: Similar to filtration, air cleaning can involve mechanical processes to remove particles.
Chemical processes: Air cleaning can also involve chemical reactions to neutralize or remove gaseous pollutants.
Biological processes: Some air cleaners use biological methods to remove contaminants.
