PAT, data trending pose challenges to environmental monitoring by Ludwig, Elisa / Validation Times The GAO study, released Monday, found that 85 percent of commercial airliners recirculate cabin air through high-efficiency particulate air filters which remove more than 99 percent of viruses and other small particles when working properly. DeFazio calls for better air quality on airliners by The Register-Guard (Eugene, OR) In addition, filtering the air with high-efficiency particulate air filters, vacuuming with machines that feature HEPA-type filtration, and covering air conditioning and hot air vents with electrostatic air filters all help to keep the air relatively free of allergens.
