Our efficacy  is documented by third parties through NF T 72-281 standard

The NF T 72-281 standard is a protocol designed by the French standardisation body AFNOR. It is designed for airborne surface disinfection systems, and it is recognized for its particularly strict fulfilment conditions. NF T 72-281 defines a set of testing methods to challenge disinfectant products in real-life conditions; efficacy data is obtained after tests conducted only according to the intended manner of use. When considering any airborne disinfectant instrument, it is important to verify compliance with NF T 72-281.

The biocidal efficacy requirements depend on the target organisms:

  • Bacteria: > 5-log reduction
  • Spores: > 3-log reduction
  • Fungi & yeasts: > 4-log reduction
  • Viruses incl. phages: > 4-log reduction
  • Mycobacteria: > 4-log reduction

STERISAFE uses the NF T 72-281 standard for all its products, and as such can guarantee their efficacy. Considering the test conditions, the high kill-level objectives it requires, and its large target range, the NF T 72-281 should be the only acceptable standard methodology for efficacy claims of airborne disinfectant products. STERISAFE has been a pioneer in using this standard in industry of the ozone-based disinfection systems, and will continue to do so.

“I was part of the expert meeting that was held in Geneva with other infection control specialists (…) and  in 2014 the NF T 72-281 norm was the first created to control AED (Automated Enviromental Disinfection) processes. I started working with this new technology using ozone and with the preliminary results I am satisfied and I think it is really promising!”

The biocidal product regulation

Biocidal products aim to protect human, animals and materials against harmful organisms such as pests or bacteria, by destroying or inactivating them. Due to their mode of action, those products can be dangerous if they enter the market with insufficient or no vigorous testing. Since September 2013, the Biocidal Products Regulation (BPR, Regulation (EU) 528/2012) acts as a legal framework with the aim to control and harmonize the rules delimiting the marketing and use of biocidal products in the European Union.

The BPR is set under the precautionary principle, and its intent is to safeguard the health of humans and the environment. All biocidal products in the EU require approval under this Regulation prior to marketing; manufacturers who overlook this requirement are operating illegally. Before acquiring any biocidal products, it is highly recommended to verify their registration under the BPR.

STERISAFE is part of the European Ozone Trade Association (EuOTA), a group composed of manufacturers of ozone generators. The EuOTA’s aim is to consolidate ozone-based knowledge amongst companies, and duly register ozone and ozone generators under the BPR.

STERISAFE upholds its products to the highest standards and can guarantee their efficacy and safety.
