What precautions can be taken?

  • Stay at least 6 feet (1.8 meters) away from people who are sick.
  • Stay home when you are sick.
  • Seek medical care if you are coughing, sneezing, and running a fever.
  • Wash your hands often with soap and water for at least 20 seconds.
    • If soap and water aren’t available, use an alcohol-based hand sanitizer with at least 60% alcohol.
  • Avoid touching your eyes, nose, and mouth with unwashed hands.
  • Cover your cough or sneeze with a tissue, then throw the tissue in the trash.
  • Clean and disinfect frequently touched objects and surfaces using a household cleaning spray or wipe.

Indoor Air Quality

The world’s leading health-related organizations consider PM10, PM2.5, and PM1 fine dust fractions as the most important and dangerous for humans.

Particulate Size and Air Filtration

Our ability to measure and identify particulate and airborne molecular contamination changes the way we think about air filtration. Because these particles are so small, viruses and other contaminants can penetrate deep into the lungs and bloodstream, where they pose a grave threat to human health. Fortunately, proper air filtration has been proven to reduce the spread of viruses and other contaminants. For example, research has demonstrated that appropriate air filtration limits the pass-through of virus particles, which frequently hitch a ride on larger particles, into downstream areas. This result may be achieved with MERV 14-16 air filters, as well as with high-efficiency particulate air (HEPA) filters, when installed in suitable air handling systems.

With the onset of the COVID-19 pandemic, AAF Flanders is focused on supplying filters to essential businesses, including healthcare and pharmaceutical industries. While some of the higher grade filter media ( ≥ 95%) AAF Flanders utilizes could potentially be used in respiratory protective devices, this manufacturing would require qualification by The National Institute for Occupational Safety and Health (“NIOSH”). AAF Flanders manufactures air filtration products and equipment for specific applications and processes. AAF Flanders is not a respiratory protective device manufacturer. The media used in our products is not designed, specified, or tested to be utilized in respiratory protection devices.

AAF Flanders expressly prohibits the modification or use of our products in any manner for which it was not designed and specifically disclaims any liability, claims, or damages whatsoever arising out of or connected with the misuse of our products. For information regarding Respiratory Protective Devices, please refer to 42 CFR Part 84.
