Ms. Rattana Andee, Library Café owner, Lat Krabang, Bangkok was dealing with: Old books and paper creating musty odour in café; some customers allergic to book dust. The Master Ozone Generator solved it completely.
Ozone (O₃) — a powerful tri-oxygen molecule — kills 99.99% of pathogens in minutes, then reverts to pure oxygen. Zero residue, WHO and FDA approved for food-contact environments.
Ozone destroys bacterial, viral and fungal DNA with no chemical residue
Ozone breaks down odour molecules — not just masks them with fragrance
One-time machine investment; low electricity cost, no ongoing chemicals
Ozone reverts to pure oxygen; meets FDA/WHO food safety standards
One machine sanitises air environments and water systems
Clean environment slows spoilage; dramatically less waste
Run overnight; zero impact on daily operations
European and international standards — use with confidence
Replace synthetic chemicals with natural oxygen-based treatment
Installation, training, spare parts, technicians nationwide
5 customers per month reporting book dust allergy and not returning
Ozone reduces bacterial spores and old-paper odour; dust-sensitive customers now comfortable
"A book café where dust-sensitive customers can now visit — ozone expanded our customer base"
