Bangkok homeowners are discovering that hiring a cleaning service company such as CJM is no longer a cosmetic choice—it is a health imperative. Rising PM2.5 levels, dust‑mite infestations, and residual chemicals make deep cleaning the new baseline for livable homes.
From “Looks Clean” to “Lives Clean”: A Shift in Home Hygiene
“Visual shine is irrelevant if pathogens and ultrafine particles remain,” says Dr. Arisa Phongpanich, environmental scientist at Chulalongkorn University.
Modern Thais now dedicate only 15–20 minutes per day to housekeeping, according to a 2024 survey by Thailand’s National Statistical Office. Meanwhile, the Thai Allergy Association reports that 38 % of urban residents test positive for dust‑mite allergens—often traced to their own mattresses and sofas.
PM2.5, Dust Mites and Chemical Residues—The Triple Threat
| Contaminant | Why It Matters | Common Indoor Hotspots |
| PM2.5 | < 2.5 µm; penetrates lung tissue and bloodstream | AC vents, window sills |
| Dust mites | Allergen‑laden waste triggers asthma & rhinitis | Mattresses, upholstered furniture |
| Chemical residue | VOCs linked to headaches & hormonal disruption | Curtains, carpets, air‑fr |

- Queen Sirikit National Institute of Child Health (2025): Children in high‑dust homes have a 34 % higher incidence of respiratory illness within 12 months.
