About this item

• IMPROVED INDOOR AIR QUALITY: The Arm & Hammer MERV 11 Pleated HVAC Furnace Air Filter is crafted for home use to enhance and purify the quality of indoor air by minimizing airborne pollutants and pesky microscopic particles. This filter is suitable for nearly all brands and can be used in air conditioning systems, furnaces, heat pumps, and HVAC systems.
• PROUDLY MADE IN THE USA: Each air filter is manufactured and assembled here in the USA. Replacing or installing the filter is quick and easy! Simply follow the instructions on the packaging. To ensure proper fit, measure your current air filter for the exact size and compare it to ours.
• TRAP AIRBORNE CONTAMINANTS: The Arm & Hammer Max Allergen & Odor Reduction Air Filter is rated as a MERV 11, meaning it can trap up to 79% of the particles sized 3.0-10.0 microns. This filter effectively reduces airborne allergens, including pollen, pet dander, dust mite debris, microscopic allergens, smoke and VOCs.
• PROVIDE OPTIMAL DEFENSE FOR YOUR FAMILY: Better protect your indoor air with electrostatic charged media to improve and prolong filter performance by using static electricity to attract and trap smaller airborne particles. This technology outperforms 1-inch standard fiberglass home air filter models.
• REPLACE EVERY 90 DAYS: To maintain optimal filtration performance, change your home air filter at least every 90 days. Regularly replacing air filters can potentially prevent costly repairs and help reduce monthly energy use. A dirty air filter restricts air flow and forces your heating and cooling or HVAC system to work harder to keep your home at the desired temperature.
