Proven capability to eliminate 99.9% of the SARS-CoV-2 virus from the air in independent laboratory testing
The Defender's "COVID Capture Technology" has been independently tested to eliminate and destroy the SARS-CoV-2 virus.
Proven capability to eliminate 99.9% within 90 minutes and destroy over 95% within 24 hours.
Independently tested by a University Hospital Infection Control Team
Conclusion from a hospital testing the FilterQueen Defender air purifier (FQD):
"Despite its compactness and significantly lower price (80% less as compared to standard mobile HEPA filters), the FQD has shown to be highly effective in purifying air, as expressed by the lower particle count and absence of fungal spores within 1 hour.
Based upon this experience, we decided to purchase multiple FQD devices that are now routinely used throughout the hospital in high-risk settings, such as during construction works or to prevent airborne infection in isolation rooms."
Used by doctors to mitigate the risk associated with aerosolized infections
From waiting rooms, the crowded lobbies, to patient rooms, medical professionals are using the Defender air purifier to help. See what doctors are saying:
"With the amount of patient traffic and doctors we have in our clinic, I've gone ahead and put the Defender in each of our three office locations to try to mitigate the risk associated with aerosolized infections."
