ULV vs Spray Bottle vs Wiping — Which Actually Kills Germs?
Comparing the 3 most popular disinfection methods — effectiveness, time, cost, real results
Real Story: A Kindergarten in Bang Yai District
A 4-classroom school with 80 children tested 3 methods. Month 1 — staff wiping (28 RSV cases). Month 2 — bottle spray (12 HFMD cases). Month 3 — switched to AIROFOG U260 + Chemgene every 7 days (only 2 unrelated mild fevers). Parents thrilled, teachers no longer stressed. The sprayer + chemical cost was 1/3 of medical bills they avoided.
3 Methods — Wildly Different Results
Side-by-Side Comparison
| Feature | Wiping | Spray Bottle | ULV AIROFOG U260 |
|---|---|---|---|
| Kills airborne germs | No | Barely | Yes — 99.99% |
| Reaches corners | No | Partial | 5-50 micron mist reaches all |
| Time / 50 sqm | 90 min | 30 min | 8-10 min |

Method 1 — Traditional Wiping
Pros: Cheap to start, immediate, visibly clean
Limitations:
- Only kills germs you actually wipe (about 40% of surface area)
- Airborne germs, under furniture, AC — untouched
- Cloths themselves spread germs if not changed/laundered
- 60-90 min for 50 sqm
- Heavy chemical usage
Method 2 — Spray Bottle
Pros: Wider coverage than wiping, faster, less chemical
Limitations:
- Large droplets (100-500 micron) don't drift, don't reach corners
- Can over-wet electronics
- Strong odor — long ventilation
- 2-3 day residual with quality chemical
Method 3 — ULV Fogger AIROFOG U260
Pros — addresses every prior limitation:
- 5-50 micron droplets drift to cover 100% of the room

- 14-day residual (with Chemgene HLD4H Medical Grade)

Cons: Sprayer investment ~30,000 THB (5-10 year lifespan); 30-min learning curve; needs medical-grade chemical

FAQ
