It is sometimes claimed to be able to achieve useful disinfection results even with 1-4 ml of hydrogen peroxide-containing (active substance concentration 3-5%) disinfecting agent per m3 of air ...
This is not completely a lie, but you have to see such statements in the right proportions.
If a space of 5m x 4m x 2.5m = 50m3 or 85m2 surface (floor, walls, ceiling) is loaded with 1ml / m3, the concentration of active substance reaches 0.59 ml / m2.
Ideally, such dosage is barely sufficient on a perfectly pre-cleaned area with weak test bacteria such as e.g. E-Coli to achieve a measurable result with Log 1-2.
Claims that it would be possible to reach log 4 (99.99% germ reduction) with such low dosages are certainly dubious!
According to our experience, for simple standard disinfection with different aerosol devices, at least 8 ml / m2 of disinfectant (with at least 5% hydrogen peroxide concentration) is required.
For more demanding tasks, such as an AFNOR NFT 72-281 test, volume and concentration must be increased accordingly.
