Validation of air cleaning systems

Does your air cleaning system remove SARS-CoV-2?

To discuss your needs

Why do you need to test your air cleaning devices?

Validating claims – ensure staff safety

Having an air cleaning system in place that can effectively remove and inactivate SARS-CoV-2 can help protect employees from COVID-19. Despite some devices being marketed in this way, if these claims of effectiveness against SARS-CoV-2 have not been validated, then a business cannot be sure that it is protecting staff or creating a COVID-secure environment.

The need for these systems to be independently validated was highlighted in a recent position paper by the Scientific Advisory Group for Emergencies (SAGE). The paper identified a lack of robust scientific data supporting the efficacy of such systems against relevant test organisms under realistic in-use conditions.

Identifying potential chemical hazards

SAGE’s paper also identified the potential chemical hazards associated with some air cleaning systems, including CO2 and ozone. It is important that these devices are tested to ensure that levels of these substances do not exceed recommended maximum levels under in-use conditions.

How can we help?

With our purpose-built aerobiology laboratory capable of representing factory conditions, our team of experienced microbiologists has developed a new test procedure to validate air cleaning systems on a scale not replicated elsewhere in the UK.

Whether your device uses UV-C light, plasma, filters, chemical sprays or any other mechanism, we can use our method to determine:

  • Air activity: Assess whether SARS-CoV-2 is inactivated and/or removed from the air at a range of representative conditions (e.g. cold for use in meat and poultry factories), and record levels of chemical by-products to ensure they are not exceeding exposure limits.
  • Surface activity: Assess whether SARS-CoV-2 is inactivated and/or removed from surfaces at your facility, whether that’s an office, hotel room, bus, train, lift or canteen, to help you determine whether these technologies are effective and safe for a specific area (before you invest in one).

Why choose us?

What makes our new method unique is:

  • Our experts’ extensive experience of controlling viruses
  • Our surrogate organism (which is structurally similar to SARS-CoV-2), and
  • Our specialist aerobiology laboratory that can validate systems on a scale seen nowhere else in the UK.

Need your air cleaning systems testing? Whether you have installed one of these systems and want to ensure it is protecting your staff or you manufacture these devices and are looking to validate claims, get in touch with our experts and find out how we can help you.
