United Airlines announced that it is adding Zoono Microbe Shield, an EPA-registered antimicrobial coating that forms a long-lasting bond with surfaces and inhibits the growth of microbes, to the airline's safety and cleaning procedures for its entire fleet. United is currently applying the coating each week on more than 30 aircraft to seats, tray tables, armrests, overhead bins, lavatories and crew stations and expects to add this latest measure to all of its mainline and express aircraft before the end of the year.

The 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. Toby Enqvist, United’s chief customer officer, said that as part of the airline’s layered approach to safety, antimicrobials are an effective complement to its hospital-grade HEPA air filtration system, mandatory mask policy for customers and daily electrostatic spraying.
