How influenza walked desk to desk until a whole floor collapsed — and how the AIROFOG U240 ULV fogging machine broke the cycle.
May, 36, is HR Manager at an advertising agency in Asoke, Bangkok — 120 staff on one open-plan floor. In mid-January, a creative came in with influenza because a major pitch was days away. He sat coughing in the middle of the room all day.
A week later, eight of the creative team were down. Two weeks later it reached Accounts and Media. On the third Monday of the month, May opened her inbox to 30 sick-leave emails in a single day — a quarter of the company. The pitch, three months in the making, was postponed. The client was unhappy. The hidden cost of stalled work ran to hundreds of thousands of baht.
Management asked her directly: “What measures do we have so this never happens again?” Her honest answer at the time: hand gel and masks in the first-aid cabinet. Everyone knew that was not enough.
Modern offices seat people close together for collaboration — a dream environment for respiratory viruses. Cough droplets cross desks; the AC recirculates the same air all day; shared touchpoints number in the hundreds: meeting rooms, microwave panels, water dispensers, copiers, door handles. Influenza peaks twice a year in Thailand, and workplaces are among the main transmission sites for working-age adults.
The invisible cost: every sick day carries salary, stalled tasks and the load colleagues absorb. One outbreak in a 120-person company costs many times the price of a fogging machine.
May consulted the building’s cleaning contractor, who pointed to what hospitals and international schools use: ULV disinfection with the AIROFOG U240 ULV fogging machine from Germany, supplied by World Health Disinfection.
The 15-30 micron mist drifts across the whole floor, treating the air, desks, keyboards, meeting rooms and every shared touchpoint at once. What wiping takes three hours to do, the U240 does in 20 minutes. The cleaning team fogs every Friday evening after staff leave; the office stays closed overnight and Monday opens to clean air.
| Before | After |
|---|---|
| Floor-wide flu outbreak, 30 staff off sick in one day | No cluster outbreaks at all the following flu season |
| Major pitch postponed, client unhappy | Projects running without simultaneous-sickness disruption |
| Record quarterly sick-leave numbers | Sick days down over 40% the next quarter |
| Hygiene measures: hand gel and masks | A weekly fogging system staff can see and trust |
“When I proposed buying the machine, management asked if it was worth it. I showed them the sick-leave numbers and the postponed pitch — approved in five minutes. Now Friday-evening fogging is routine. Some staff have told me that just knowing the company cares this much makes them happier to come in.” — May, HR Manager, advertising agency, Asoke
Q: Will Monday morning smell of disinfectant?
A: ULV mist dries within hours; a short run of the ventilation system Monday morning leaves no residual smell.
Q: Is IT equipment safe?
A: The ultra-fine mist carries very little liquid — no drips, no pooling. Choose non-corrosive solutions per WHD guidance; standard offices are fine.
Q: Our carpets and fabric chairs trigger staff allergies. What helps?
A: Add WHD’s on-site dust mite removal service every six months for deep carpet and chair extraction.
Q: We occupy several floors — do we need several machines?
A: One portable unit covers multiple floors per session; consider a second only for areas of several thousand square metres.
It starts with 20 minutes every Friday evening.
