20x20x1 AC Furnace Air Filter

Enhance the air quality in your living space with the 20x20x1 Air Filters from Custom Filters Direct – your reliable source for top-of-the-line HVAC solutions. Keep your furnace, air conditioner, heat pump, or HVAC system running efficiently while enjoying the benefits of cleaner, healthier air.

Key Features:

  • Versatile Replacement: Measuring precisely 19.50″ x 19.50″ x 0.75 inches, this filter is ideal for use as a replacement in your HVAC system, heat pump, furnace, or air conditioner. For best results, make sure it fits perfectly.
  • Advanced Filtration: These filters give a high level of protection by capturing 98% of airborne particles. They are equipped with MERV 13 synthetic media. It efficiently blocks germs and other airborne pollutants out of your home without sacrificing airflow, making it comparable to MPR 1500-1900 and FPR 10 ratings.
  • Sturdy Construction: We use premium materials to guarantee the lifespan and effectiveness of our air filters. Compared to conventional fiberglass models, the filter’s lifespan is trebled because of the electrostatically charged, pleated design, which collects more hazardous particles.
  • Strong Frame Design: The beverage board frames made of industrial-grade material that are combined with two wire backings work better than cardboard models. In even the most severe HVAC situations, this guarantees structural integrity, robustness, and dependable performance.
  • Eco-friendly and American-made: You may relax knowing that our air filters are made in the USA using only premium parts that meet rigorous quality requirements. Because we are environmentally conscious, we use recyclable materials in the design of our filters to reduce their influence on the environment.
