Accumulair® Gold is an air filter designed with better air quality and higher filtration efficiency in mind. It is given an APR 650 filter rating, which means that it is a medium-efficiency filter that removes airborne particles smaller than 1 micron. This means that it removes a large variety of indoor air pollutants, including dust mites, bacteria, mold spores, pet dander, pollen, lint, and smoke. Unlike regular fiberglass filters, the Accumulair® Gold filter uses electrostatic filtration, which is a special filtration media that uses an electric charge to attract and trap air particles. With a dust spot efficiency of 30-35%, the Accumulair® Gold filter removes 20 times more particles than ordinary fiberglass filters. Even with high particulate efficiency, it manages to maintain low resistance to airflow. Accumulair® Gold filters are available in many different sizes, but they can also be custom made to fit any desired filter system.
