Size and Fit
Make sure the filter fits your HVAC system properly. Komtfil offers standard box filters with single header, double header, or no header options, plus small footprint designs for space-saving installations. Getting the right size ensures maximum filtration efficiency and airflow.
Application Environment
Consider where the filter will be used. For commercial box filters exposed to humidity or moisture, choose Komtfil’s moisture-resistant box filters made with galvanized construction to prevent rust and damage.
Pressure Drop and Longevity
Look for filters with low initial pressure drop to keep your system energy-efficient. Komtfil’s advanced separator designs help maintain airflow while capturing airborne contaminants. Regular maintenance will extend your filter’s lifespan and system health.
