Nordic Pure Effectiveness

Nordic Pure Convenience Factor

All of our air conditioner and furnace filters feature Ultra High-Efficiency reduction by employing a pleated filter with electrostatic charged synthetic media. The highly efficient electrostatic air filter media attracts dust and pollen like a magnet.

Nordic Pure AC filter and furnace filters capture 97.8% of the microscopic airborne dust, pollen, allergens, mold spores, pet dander, bacteria and particulates carrying bacteria and viruses in the air.

Premium performance construction with a high-dust holding capacity. Nordic Pure air conditioning filters and furnace filters exceed MERV 12 rating. (MERV 7 available upon request.)

Recommended replacement of furnace filters (including your vent register filters) is every 30 to 90 days for 1 inch filters and every 3 to 6 months for 4 inch and 5 inch.
