• We recommend you enhance the filtration in your HVAC system to exceed what the current minimum code requires for your building.
• Larger horsepower (HP) fans should upgrade to higher MERV (Minimum Efficiency Reporting Value) filtration options.
• Fractional HP fans (e.g., fan powered terminal units and fan coil units) may not have that option.
• Please consult with our specialized team to evaluate your options on a case-by-case basis.
