Perfect fit, lasts a long time, and a great price.
Pattern Name: 20x20x1, Style: Merv 5
These filters are a perfect size, they're well-made (I don't notice any more dust in the house than "normal"), and so far, they last longer than I had expected (they're made to last 30 days, and the one I have in has lasted 90 days). So for this 6-pack, what should have lasted 6 months may actually last more like 3 years! And these are the best deal I could find on the internet. I'd definitely recommend them.

Well Made and Beefy 💪🏼🏆
Pattern Name: 20x20x1, Style: Merv 11
Some air filters are wobbly and cheaply made, but not these. Amazon didn’t skimp when they sourced these. They are as good as any name brand filter. We use these on Pelonis box fans to aid in filtering the air, and keep air moving🌬️✨

Great value filters – do the job well
Pattern Name: 12x12x1, Style: Merv 8
These filters are a great value for the price, especially getting a 6-pack. They fit perfectly (just keep in mind the actual size listed), and installation is quick and easy.
I’ve been using them regularly and they do a solid job catching dust and keeping the air clean without restricting airflow. Good balance between filtration and performance.
Nice to have multiple on hand so I can swap them out regularly without thinking about it. I’ll definitely keep buying these.

Great Value Air Filters
Pattern Name: 20x20x1, Style: Merv 11, Pattern Name: 20x20x1, Style: Merv 11
These Amazon Basics air filters fit perfectly and were easy to install. They help keep the air cleaner and the HVAC system running smoothly. Good quality for the price, and the 6-pack is convenient to have on hand for future filter changes. Definitely a great value purchase.
