MervFilters MERV 8 AC Furnace Filters 6PK (Open Box)

I’ve been using the Simply 20x24x1 Air Filters (MERV 8, MPR 600) for a while now, and they’ve exceeded my expectations for a mid-range filter. With pets in the house and some seasonal allergies, I needed something that could handle more than just basic dust—and this filter delivers. The actual size (19.75" x 23.75" x 0.75") fits snugly in my system, and installation was quick. The MERV 8 rating is a noticeable upgrade from lower-rated filters—it's able to trap dust, pollen, pet dander, and even some smaller particles that often make it past cheaper options. Since switching, I’ve noticed less dust on surfaces and a subtle but real improvement in air freshness. Each filter lasts about 2–3 months depending on air quality and usage, and with six in a pack, it’s a cost-effective way to stay on top of filter changes without constantly restocking. For anyone needing solid filtration without jumping to premium prices, this is a great choice—especially for households with pets or mild allergies. Pros: Effectively captures dust, pet hair, and pollen Good fit and easy to install 6-pack is convenient and budget-friendly Noticeable improvement in air quality Cons: May need more frequent changes in homes with multiple pets Not suitable for ultra-fine particles
