Filtering the air before heating/cooling reduces airborne contaminants and increases your comfort. Return vent filters are suitable for air conditioners and furnaces as well. There is little that can be done to improve the quality of the air that is being circulated through the system aside from replacing the air filters. The selection of your HVAC system’s air filters directly affects the quality of air being circulated throughout the system.

Air circulating throughout the return air ducts contains countless contaminants including allergy triggers that you cannot see, but show up as "black soot" on the wall area surrounding the air intake vents.  Dust and debris constantly enter the HVAC system, and cause build up throughout the ducts and on furnace components.  In homes with vent ducts built into the floors, high amounts of dirt fall into the ventilation system, especially in high foot traffic areas.  A way to combat that would be to install Nordic Pure electrostatic filtration media in the intake vents and return vent air filters.

All of our filters feature ultra high-efficiency reduction by employing a pleated filter with electrostatically-charged synthetic media. The highly efficient electrostatic filter media attracts dust and pollen like a magnet. As much as 97.8% of the microscopic airborne dust, pollen, mold spores, pet dander, bacteria and particulates carrying bacteria and viruses in the air are captured.

Return air vents draw air to be circulated back into the air conditioning unit or furnace from the house to be cooled or heated and supplied to the rooms. Our Merv 12 anti-allergenic pleated air filters significantly reduce dust, mold spores, pet dander, pollen, smoke particles, and other indoor air contaminants by up to 97.8%. We'll not only improve your indoor air quality, but you may be able to dust less and your allergies may not be as bad since you have less indoor air pollutants driven through your return vent filter. Our filter media has a permanent electrostatic charge and does not support the growth of bacteria, fungi, mildew or mold.
