· Technology · Technical · Deodorizing filter

Deodorizing mechanisms can be classified into 4 types. Most deodorizers as consumer goods consist of air freshener, deodorizer, and complex mechanism product which combines these two.

Adsorption effect : Activated carbon is used as adsorbent which adsorbs smell

Catalyst response : Decomposes malodorous particle using catalyst. 3AC produces deodorizing effect using two factors (adsorption & catalyst)
