Enhanced HVAC Filtration

  • 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.
