Physical filtration air purifiers, when paired with activated carbon filters, are most effective in removing both particulate and gaseous pollutants.

Firstly, for particulate pollutants such as PM2.5 and dust, physical filtration air purifiers are recommended due to their efficient filtering capabilities. This type of air purifier typically uses HEPA filters, which can effectively intercept fine particles. For example, tower-structured air purifiers equipped with H13 grade HEPA filters and ample activated carbon filters can provide high single-pass filtration efficiency.

Secondly, for gaseous pollutants such as formaldehyde and benzene, activated carbon adsorption is currently the most widely used and assured method of purification. Activated carbon has a porous structure that can effectively adsorb gaseous pollutants, thereby improving indoor air quality.

Furthermore, when selecting an air purifier, in addition to considering the purification technology, attention should also be paid to the following important parameters:

CADR Value: The Clean Air Delivery Rate, indicating how efficiently the air purifier cleans the air; the higher this value, the more efficient the purifier is.

CCM Value: Represents the cumulative capability of the filter to purify pollutants; a higher value indicates a longer filter lifespan and better adaptability to severely polluted environments.

In summary, when choosing an air purifier, one should comprehensively consider its purification technology, filter type, CADR value, and CCM value among other parameters.
