MERV 8, Poly Cube Filters Poly Cube Air Filters are a type of air filter designed specifically for use in HVAC (Heating, Ventilation, and Air Conditioning) systems. They are made from a polyurethane material that is durable and long-lasting. Poly Cube Air Filters are known for their high dust-holding capacity, which means they can effectively trap and retain more particles than traditional fiberglass filters. This helps to improve indoor air quality by reducing the amount of dust, pollen, pet dander, and other allergens circulating in the air. These filters are also designed to have a low resistance to airflow, which means they won't put unnecessary strain on the HVAC system. This can help to reduce energy consumption and prolong the life of the system. Poly Cube Air Filters are available in various sizes to fit different HVAC systems and can be easily replaced when necessary. They are an affordable and effective solution for improving indoor air quality and maintaining the efficiency of HVAC systems.<p> <a href="/Downloads/Brookaire%20Cubes.pdf" target="_blank">Downloadable information sheet.</a> </p>
