Furnace Filters, Air Conditioning Filters at Air Sponge Filter Company


The problem with "most" furnace filters
Airflow naturally seeks the path of least resistance. Since thin cardboard furnace filters provide a poor perimeter seal, as they get dirty, resistance across the filter increases and pollution tends to leak around the frame edges, thereby completely avoiding filtration. For higher efficiency furnace filters, this problem is multiplied! This leakage causes your air conditioning coil to become contaminated, and unhealthy.
HealthSmart furnace filters are up to 600% more effective, in capturing harmful fine particles such as mold, bacteria, viruses and fungi, compared to those cardboard throw away type furnace filters. We developed the patented HealthSmart Filter system, furnace filters specifically designed to overcome the flaws of flimsy inefficient cardboard furnace air filters.
