Hummingbird™ Air Purification System deactivates 99.99% of airborne COVID-19, Omicron and Delta variants, affirming hummingbird™ efficacy as a long-term indoor air quality solution - tested at USC Keck School of Medicine.

November 29th, 2022 - SAN DIEGO, CALIFORNIA.

With COVID-19 continuing to mutate and healthcare experts warning of a ‘tripledemic’ of respiratory diseases of RSV, Flu and COVID-19, it’s more important than ever to mitigate the spread of these diseases. Indoor airborne transmission has shown to be one of, if not the primary transmission vectors. One of the best ways to stop transmission is with a building level air purifying solution such as hummingbird™ which can protect whole commercial buildings and residences.

As COVID-19 variants have mutated, pharmaceutical companies have had to re-tool the vaccines to adapt to mutations. “Our goal of going back to test efficacy vs. variants is to prove that the Hummingbird™ system does not need alteration to handle variants. It has proven to effectively handle any variant we tested, therefore making it a good long-term solution and investment to protect buildings.” – John Carrieri, CEO. Hummingbird™ was tested and has proved effective in deactivating the Beta, Delta, Omicron, BA.2 variants in additional to the original COVID-19.

Energy Cloud set out to prove out its hummingbird™ system can deactivate COVID-19 in realistic building HVAC (heating air conditioning & ventilation) systems with realistic airflows. The system won an Edison Award in 2022 for its testing with realistic HVAC airflows and efficacy against COVID-19. Initial testing began in 2021 and continued throughout 2022. The expanded testing in 2022 included testing the system up to 2,000 CFM per unit. The units can be added together to handle larger airflows. What is so important about testing with realistic airflows, is it makes the difference on whether testing has any meaning at all. "Any technology that claims to protect a building through its HVAC system, that doesn’t test with realistic airflows, has a meaningless test. 99.x% numbers mean nothing without a proper test." – John Carrieri, CEO of Energy Cloud Inc. The system was also tested with a large 3,000x+ infectious dose of COVID-19 and each variant to further prove it could handle the largest commercial buildings.

Hummingbird™ deactivation of the virus – known scientifically as SARS-CoV-2 – was independently tested and proven at the University of Southern California (USC) Keck School of Medicine, with all Biosafety Level 3 (BSL-3) work performed within The Hastings Foundation and Wright Foundation laboratories. SARS-CoV-2 BSL-3 resources were supported by a grant from the W.K. Keck Foundation’s COVID-19 research fund.

Hummingbird™ has many additional features in addition to its virus efficacy:

Medical Lab Quality Air Purification

hummingbird Air purification technology that decomposes VOCs and reduces bacteria, microbes, pollen, dust, dander, allergens, spores, fungi, mold, odors, smoke and toxic fumes without producing any harmful ozone or biproducts.

Indoor Air Quality Monitoring

hummingbird includes Indoor air quality monitoring with real-time air quality information for customers, employees and property owners, for all stakeholders to see the building air quality through Energy Cloud’s air certification. The information can be seen through a QR Code displayed on the buildings outside doors and windows as well as web URL links that can be viewed on any computer or smart device. Building owners who invest in having the best air quality for their buildings and business can show proof of their air quality with the QR code and unique URL provided for each building..

HVAC AI & Remote Management

hummingbird AI technology allows cloud-enabled remote monitoring and management of HVAC systems, saving energy by providing real-time insight to equipment operation and efficiency.
