Filtrete 24x36x1 AC Furnace Filter - MERV 8, MPR 700, 4-Pack

Improve your indoor air with Filtrete 24x36x1 AC Furnace Filter

Designed for busy households, Filtrete pleated filters use electrostatic media to attract and trap a broad spectrum of particles as your air cycles through heating and cooling equipment. This set includes four filters, each built for a three month life, so you can stock up and reduce frequent trips to the store. The actual size is 23.81 x 35.81 x 0.65 inches, tailored to fit most standard 24x36x1 frames on furnaces and air conditioners. The filtration media is engineered to capture lint, pollen, dust, and pet dander with a focus on cleaner air while keeping a steady airflow through your system.

In practice, you may notice the air in living spaces feeling crisper, with less visible particle buildup on surfaces during peak allergy seasons. The filtration system works with your HVAC equipment to balance performance and air quality, using a three-in-one approach from Filtrete that targets different particle sizes without overly restricting airflow. The label indicates a MERV 8 rating and an MPR 700 rating, which reflect an emphasis on capturing a range of common indoor pollutants while remaining compatible with typical home systems. The filter is designed for replacement every 90 days, though you may choose to adjust this cadence based on household activity, pets, or seasonal changes.
