In response to the COVID-19 pandemic and the growing emphasis on enhancing indoor air quality, guidelines from ASHRAE, CDC, and OSHA have been introduced that strongly recommend the adoption of MERV 13 filters. This recommendation stems from MERV 13's exceptional capacity to filter out particles ranging from 3.0 to 0.3 microns. When implemented correctly, MERV 13 filters can deliver air quality enhancements comparable to those provided by HEPA filtration systems.
