Defend Portfolio

The 24/7 Defend Air Purification Portfolio offers in-ceiling solutions for UVC air disinfection and MERV 13 air filtration. 

These air purification options are recognized as best practice solutions by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), the Centers for Disease Control and Prevention (CDC), and the Environmental Protection Agency (EPA) Clean Air in Buildings Challenge  for spaces needing improved air quality.  Additionally, in early 2023 the CDC updated its ventilation guidance* stating that, when possible, aim for 5 or more air changes per hour (ACH) of clean air to help reduce the number of germs in the air.

Armstrong’s 24/7 Defend products offer in-ceiling air cleaning that works up to 35%** more effectively than floor-based air cleaning and are part of a long-term strategy to improve indoor air quality.
