Milwaukee County Transit System (MCTS) maintenance crews are using a new air filtration product on buses to help prevent the airborne spread of viruses — including the one that causes COVID-19.
The Aeris Guard Bioactive Filter Treatment spray coats the HVAC filter of each bus with a polymer system that controls bacteria and pathogens for up to three months. The application of the spray is reported to increase filtration efficacy without straining vehicle ventilations systems or decreasing airflow, according to product developer Aeris Environmental.
“Throughout the pandemic, MCTS has worked to ensure that buses continue to safely serve county residents. The introduction of this innovative air filtration treatment system is just the latest tool we’re using to keep our employees and riders safe,” said Milwaukee County Executive David Crowley. “I ask all residents to continue doing their part to end the pandemic by getting vaccinated, wearing a mask in crowded settings like on public transit and following other best health practices.”
Wisconsin is an open state with no COVID-related restrictions, but riders on MCTS’ system are still required to wear masks to be in compliance with the Transportation Security Administration’s order, which was extended through Sept. 13.
“We’re excited to partner with Milwaukee County on this first deployment of the Aeris COVID defense system on an American public transit system,” said Aeris CEO Peter Bush. “Passengers can ride with peace of mind knowing they now receive the same protection from COVID-19 that other parts of the world have on a daily basis, after adopting this technology.”
