Cleanroom and aseptic area decontamination with VH₂O₂
VH₂O₂ decontamination means releasing hydrogen peroxide vapour into a sealed room so that it spreads over all surfaces and destroys microorganisms. At the end of the cycle the vapour breaks down into water and oxygen. It suits cleanrooms and laboratories that need aseptic conditions.
How VH₂O₂ differs from conventional disinfection
| Topic | Manual wiping or chemical spraying | VH₂O₂ |
|---|---|---|
| Coverage | Depends on the operator, may miss some areas | Vapour spreads throughout the room |
| Residue | May leave residue that has to be wiped again | Breaks down into water and oxygen |
| Consistency | Varies from one application to the next | Repeatable, controlled cycle |
Examples of our work
How we provide the service
- VH₂O₂ decontamination: the main method for cleanrooms and aseptic areas
- Manual surface disinfection: for frequently touched surfaces and complex equipment
- Inside the cleanroom only: duct cleaning and fogging into ductwork are not included
Suitable areas
Pharmaceutical cleanrooms · Laboratories · Operating and isolation rooms · Food production areas
Frequently asked questions
What does VH₂O₂ break down into?
Water and oxygen, so it leaves no residue that has to be wiped off.
When can people re-enter the room?
When the hydrogen peroxide concentration in the air has fallen below the specified safe level, which must be measured before the room is opened every time.
How is the decontamination verified?
QV TEST verifies results with biological indicators (BI) and chemical indicators (CI) placed at points the vapour finds hard to reach, the method widely used in the pharmaceutical industry.
