Regional Transportation District (RTD is Improving The Air Quality in its Buses with Merv-13 Equivalent Filtration

Denver, Colorado, United States, February 16, 2023 / -- Bill Weidenaar, Technical Services Manager for RTD, said, “Improving air quality is part of RTD’s commitment to a cleaner, healthier environment for our customers and operators. By upgrading to MERV-13 equivalent filtration, we are capturing and removing a greater number of contaminants from the air.”

Nick Rorres, Equipment Engineer for RTD, added, “Our pre-purchase testing showed excellent airflow through Lumin-Air’s filters. Lumin-Air’s filters were easy to adapt to our buses, and replacement filter media is very economical.”

“We’re glad to be a part of RTD’s commitment to improving the air quality on its buses. Higher efficiency filtration is the most common and effective way to improve air quality, and it doesn’t add chemicals, ions or gases to the air people breath. A visual example of our filters removing ultrafine particulate matter like smoke from the air can be found on our website,, or on YouTube, Lumin-Air Smoke Filtration, ” said Lumin-Air’s Dan Fillenwarth.
