Better filtration is the first step in improving Indoor Air Quality. Pleated Panel Filters outperform ordinary furnace filters with higher efficiency and lower pressure drop allowing air-handling systems to stay cleaner and operate more efficiently. We achieve this with 100% synthetic electrostatically charged gradient density media, optimum pleat spacing and high initial and sustained efficiency, high dust holding capacity and very low pressure drop. The media is resistant to a wide range of chemicals, does not absorb moisture and will not support microbial growth.
Benefits:
- Great for helping reduce airborne allergens such as bacteria, particles that carry viruses, pollen, mold spores, fine dust, and pet dander.
- Filter material will not support the development of mold, mildew, bacteria or other microorganisms in normal use.
- No chemicals added. Filters are chemical free!
- Over 30-times more efficient at capturing micro particles than ordinary fiberglass filters.
- Lasts UP TO 3 months!
Features:
- MERV 11 Rating
- 100% synthetic gradient media, electrostatically charged
- 30 gauge galvanized expanded metal grid
- Moisture resistant double wall beverage board
- Media pack totally bonded to frame

How to change your furnace/air-conditioner/HVAC air filter
Estimated time: 10 minutes or less
Steps
Determine the location of your filter
Your forced air system will be similar, whether or not it is a heating (furnace) or cooling (AC) system – or both. The furnace filter housing/slot is located right next to the heating/cooling system’s air handler or blower. Your filter(s) may also be located in a return grille on the wall or ceiling of your home.
Determine the type/size of filter that you use
Typically, the dimensions or part number of the filter will be printed on the filter frame. Use this information to order a new filter.
Purchase a new air filter from DiscountFilters.com
Visit DiscountFilters.com and purchase a new filter. Use our filter finders to verify the correct match.
Remove the old filter
Turn off the power to the heating/cooling system and remove the old filter from its housing/slot and discard.
Insert the new filter
Pay attention to any airflow direction arrows printed on the frame of the new filter. Install the filter by sliding it into the filter housing/slot with the airflow arrow pointing towards the blower. If installing the filter in a wall or ceiling grille – the airflow arrow should point towards the wall or ceiling. Turn on the power to the forced air system.
Enjoy cleaner air!
