At 8 a.m. on Monday, Khun Nat, a call-center team lead at an insurance firm on Ratchada Road in Bangkok, opened the roster and froze: 11 of his 24 agents had called in sick at once, all with the same fever, sore throat and cough. The whole team works in a sealed air-conditioned room with desks packed together, sharing headsets and keyboards across rotating shifts.
Customer calls kept pouring in but there were not enough agents to answer. Wait times blew past the company KPI, customers grew frustrated, and Khun Nat knew at once this was not just "everyone gets sick this time of year", it was an outbreak that started in the air of his own office.
Call centers have features that accelerate transmission: high people density, agents talking constantly and producing many droplets, recirculated air in a closed system, and shared headsets, microphones and keyboards passed between shifts. Germs travel from one person to the next with ease.
The World Health Organization (WHO) notes that poor ventilation in crowded, enclosed spaces drives respiratory transmission. When one agent comes to work already symptomatic, the infection can reach shift-mates within hours.
Health: Many agents fall ill at once, some for days, hurting both health and team morale.
Finance: With too few agents, wait-time and answer-rate KPIs drop, hitting revenue, SLA penalties, and forcing emergency overtime or outsourcing.
Reputation: Customers who wait too long or get patchy service are unhappy; some leave negative reviews that damage a hard-won brand image.
Handing out masks, placing hand gel and wiping desks helps but is incomplete: germs floating in the closed air and lodged in headset foam, keyboard crevices and AC vents remain. Effective disinfection must reach the air and every surface at once.
The facilities team chose the AIROFOG U260 ULV fogger from Germany, the same machine used by Thai Airways and hospitals. Its 15-30 micron droplets float into every corner of the workspace, including AC vents and dead spots. Used with certified disinfectant, it cuts germs by over 99.99%.
Before: A sealed, stuffy call-center floor; a chain of sick agents; falling KPIs; emergency overtime.
After: Nightly ULV fogging leaves air and equipment clean, sick days drop, the team is fully staffed, and KPIs stabilise.
"Since we fog with the U260 every night, the team rarely falls ill together anymore. SLA penalties vanished, far cheaper than overtime." — Khun Nat, call-center team lead
Q: Can agents start work right after fogging?
A: Fog during a shift close when empty and ventilate before work per the disinfectant guidance; safe for the next shift.
Q: Will it damage computers and headsets?
A: Set a fine mist and proper distance, ULV droplets will not soak equipment.
Q: Where can I see the price and order?
A: See the AIROFOG U260 product page or call 065-556-6294.
