Surgical-grade air purifiers land in Australia to tackle aerosol transmission

February 22, 2021 Medical Tourism No Comments Email Email

The Australian arm of US proptech giant Delos is importing next generation air purification units to Australia that can filter and remove COVID-19 particles and reduce the viral load within hotel rooms where infected travellers are quarantining.

The science-backed air purification units are portable, stand-alone and can be set up within minutes to offer medical-grade protection against airborne particles, including viruses and bacteria.

Delos has already installed 100,000 of the same air purification units in more than 10,000 New York City public schools and wants to speak to government departments in Australia regarding similar applications.

The air purification units reduce the chance of infection by capturing ultrafine particles. They also trap and use Ultraviolet Germicidal Irradiation (UVGI) to stop micro-organisms from reproducing, and physically remove and deactivate viruses from the air.

Research and independent third-party testing has shown that the units perform at similar standards of purification systems utilised in surgical and health care settings1, while the University of Buffalo found an efficacy rate of 99.99% in removing particles sized 0.07 microns and greater (SARS-Cov-2 particles range in size from 0.06 and 0.14 microns)2.

Delos Australia President Bill Giannikos said the air purifiers could be used in hotel quarantine to reduce potential viral load within rooms where returned travellers are quarantining, or have been diagnosed with COVID-19, thereby limiting the risk of the virus infecting workers and return travellers.

“Air purification systems are considered by many to be a critical supplementary approach to reducing transmission rates by remediating airborne pollutants and contaminants. The ‘Delos powered by Healthway’ air purification units capture ultrafine particles and can reduce particles that carry airborne bacteria and viruses.

“Traditional filters for mechanical HVAC solutions do not efficiently filter air particles as small as SARS-CoV-2 (0.06 to 0.14 microns) in occupied spaces, where it matters most. The ‘Delos powered by Healthway’ air purification units are portable, standalone units with technology that filters particles as small as .007 microns, at 99.97% efficiency.”

For more than ten years Delos has fostered research partnerships with leading medical institutions, including a collaboration with Mayo Clinic to create the Well Living Lab, the first human-centered research facility dedicated to researching the indoor environment’s impact on human health. As part of this, Delos has evaluated nearly 600 products against its evaluation criteria across 60 product types.

Delos has a number of Healthway units available in Australia and more currently being shipped from international suppliers to fulfill demand.  

They are already being offered to new purchasers within Victoria’s wellness-designed Melbourne Square apartment project in a Victorian-first agreement between Delos and developer OSK Property.

Giannikos wants to see them being installed in quarantine hotels as a defence mechanism against COVID-19 leaks, as well as schools, allied health settings and hospitality venues as a duty of care to students, staff and patrons.

“There is mounting evidence that small particles that may carry SARS-CoV-2 can remain suspended in air and can persist in aerosol form for long periods of time indoors,” he said.

“If this latest lockdown has taught us anything, it has to be the importance of indoor air quality and the way we manage it. Every building owner should be considering the quality of the air and purification systems in their current environment, as well as their responsibility to protect the wellbeing of those who spend time in their spaces.”

Delos is the founder of International WELL Building Institute (IWBI), which administers the WELL Building Standard™ globally to improve human health and wellbeing in the built environment. Delos has also launched its new WELL Health-Safety Rating in the US which helps improve the health of all indoor spaces through third-party vetting of company policies, maintenance protocols, emergency plans and stakeholder education.

In Australia it has negotiated landmark deals with housebuilders Simonds and Chatham Homes along with agreements with Ci Group and United Solar Energy for distribution of its wellness technology to thousands of Australian businesses and homes.
