The antimicrobial coating, created by Zoono Group Limited, a New Zealand Company and distributed in the USA by MicroSonic Solutions, will serve as an added layer of protection that complements the airline’s existing, daily electrostatic spraying regimen before departing flights.
“This long-lasting, antimicrobial spray adds an extra level of protection on our aircraft to help better protect our employees and customers,” said Toby Enqvist, United’s chief customer officer.
“As part of our layered approach to safety, antimicrobials are an effective complement to our hospital-grade HEPA air filtration system, mandatory mask policy for customers and daily electrostatic spraying. We’ve overhauled our policies and procedures and continue to implement new, innovative solutions that deliver a safer onboard experience.”
According to United, the Zoono Microbe Shield works by bonding to surfaces and creating a protective layer that resembles microscopic pins once dry which rupture cell walls and membranes when microbes come in contact with them.
The chemical is classified by the EPA as Category IV, which is the lowest level of toxicity. During an aircraft’s deep cleanings, United will use the NovaRover which is designed to apply a super fine mist of the antimicrobial that coats all surfaces in a 12-foot radius with a single spray.
United says it will apply the antimicrobial coating to aircraft overnight every seven days using electrostatic sprayers to refresh and fortify the protective layer, while continuing to electrostatic spray disinfectant to the aircraft cabin “before almost every departure”.
