University of Kent tests and verifies UVGI performance

Purified Air’s ultraviolet germicidal irradiation units (UVGI) have a destructive effect on micro-organisms such as viruses and bacteria. Given the seriousness of the COVID-19 pandemic and the flood of cheap products from overseas, we wanted to give our clients added reassurance that the SARS-CoV-2 virus can be deactivated by exposure to UVGI using our units. That’s why we called on the University of Kent to independently verify the efficacy of our UVGI 1000 and UVGI 1500 indoor air purification solutions. 

Each individual UVGI air purifier unit sits directly in the air stream and features high output UV-C lamps. The University of Kent team compiled a report analysing the optimal power and irradiation dose available from our UVC germicidal lamps used in airflow enclosures. The team measured the irradiance of the bulbs to check they deactivate COVID-19 and kill bacteria. They also analysed dwell time (how long air stays inside chamber) to check the air had adequate time in the unit for viruses to be deactivated. 

We are pleased to say that we passed with flying colours!
