External air filter material properties
WebIndustrial HVAC air filters are installed in commercial HVAC systems to remove airborne contaminants from the air stream. This helps improve indoor air quality and prevents the build up of contaminants in equipment and damaging it. The Minimum Efficiency Reporting Value (MERV) rating of a filter measures how efficiently it removes contaminants ... WebHigh-efficiency particulate air (HEPA) filters meet those requirements and are able to remove particles of 0.3 μm or larger and may even remove particles much smaller than this. They have efficiencies of 99.97–99.997% retention for particles of 0.3 μm or larger.
