  • MERV 11 Rating
  • Supercharged pleated panel filtering media ideally suited for capturing fine airborne allergens such as dust, smoke, dander, mold, pet dander, and dust mites - attracts particulates like dust to a TV screen.
Uniform pleat shape enhances dust holding capacity and maximizes air flow.
Heavy duty construction frame prevents airflow bypass.
    Merv 11 furnace filters and AC filters can remove mold spores, pollen, dust, lint, pet dander and more. Pleated furnace filters and pleated AC filters provide a higher level of protection from indoor air contaminants compared to fiberglass air filters. In contrast to cheap filters, pleated home air filters can effectively trap pet dander, mold and even smoke or bacteria. Today, people spend up to 90% of their time indoors. This makes the air we breathe inside important to our short and long-term health. Indoor air pollutants such as household cleaning products, mold and pet dander can be effectively cleaned from the air when a home's air filter is changed every 90 days or sooner. Don't risk you or your families health. Be sure to follow the manufacturer recommendations and even change your HVAC filter sooner if it is dirty when checked.
