Vaporized(VHP) vs Aerosolized(aHP)

Aerosolized Versus Hydrogen Peroxide Vapor

All decontamination technologies are not created equal, let alone all hydrogen peroxide based technologies. While the wording may sound similar, major differences between aerosolized hydrogen peroxide (aHP) and Hydrogen Peroxide Vapor exist. Sifting through the jargon and understanding the differences can reduce HAIs and save lives.

Due to the uniform application procedure of hydrogen peroxide vapor, the vapourised method has a track record of more than 6-log uniform pathogen reduction in clinical trials, whereas aerosol hydrogen peroxide systems perform inconsistently, with results of 4-log pathogen reduction or lower. What’s more, aerosol hydrogen peroxide systems are usually installed within the room and stationary, leading to incomplete and non uniform distribution of the decontaminant, as well as varying levels of pathogen inactivation throughout the enclosed space.

C.difficile(Clostridium difficile- Diarrhea), as example, is a resistant pathogen found in hospitals.   Studies show that aerosol hydrogen peroxide systems manage an 85-89% elimination of C.difficile, while hydrogen peroxide vapour decontamination results in 100% elimination.    In addition, hydrogen peroxide vapor has an even distribution, short cycle time, and is consistently reliable, making it the obvious choice for bio decontamination.

Key differences between vaporized and aerosolized hydrogen peroxide

More Effective with Less

According to a study in Infection Control and Hospital Epidemiology (ICHE), a single Oxymist system was more effective and faster than 2 aerosolized hydrogen peroxide units. The aerosolized units failed to deactivate 50% of the biological indicators over a series of tests, while Oxymist achieved a 100% success rate.

Always One Active Ingredient

Oxymist Hydrogen Peroxide Vapor technology only uses a 7.6% hydrogen peroxide solution with no other active ingredients. Various aerosolized options will attempt to account for a lower hydrogen peroxide level, ranging from one to twenty percent, with additives such as peracetic/acetic acid, silver nitrate and orthophosphoric acid being distributed in your patient rooms.

Invisible and Comprehensive Distribution with Repeatable Results

Hydrogen Peroxide Vapor will encompass every exposed surface in an enclosed area, providing consistent efficacy throughout. The unique properties of the vaporized process allow for this to occur even on complex shapes or tough to reach areas. Users of aerosolized hydrogen peroxide will discover inconsistent results, larger visible droplets and areas minimally impacted by the process.
