Effects of Installing Air Sterilization and Deodorization (UV + Photocatalyst Option) Ventilation Units

Sterilization, Deodorization, and Removal of Total Volatile Organic Compounds

Sterilization Deodorization Removal of Total Volatile Organic Compounds (TVOCs)
Direct oxidation by UV radiation inhibits For gases such as hydrogen sulfide, Excellent efficacy in removing organic
microbial growth (germs, viruses, and mercaptans, amines, and other irritating compounds such as formaldehyde, which is
bacteria) by enclosing them and blocking substances, the molecular structure is broken a major cause of sick building syndrome.
