Been using the 20x25x4 for multiple years now. Filters work great, I replace mine every 90 days in my house. Never had any issues or concerns about quality or construction of the filters. I've seen many complaints about the 1" thick filters and while I understand their concerns; a 1" thick filter is old technology and should consider getting a larger filter box. I find the complaints about the tabs holding the pleats in the filter where you may have to push a few back trivial. You're buying a MERV 11 equivalent disposable filter, again DISPOSABLE. It wasn't long ago when everyone was just using the blue fiberglass air filters.. There is a balance between retail cost and manufacturing cost. If they raised prices to appease everyone, they'd complain the filters are too expensive even though build quality is excellent!. Your Neighbor. Indiana. Wed Dec 21 2022

Durable, stainless steel, baffle filter for use with select Zephyr range hoods. The interlocking baffles allow for more capture of grease in the filters due to the rapid flow of changing air direction. As grease is heavier than air, the grease stays trapped on the baffles and promotes better air flow within your kitchen. Please check your Zephyr range hood's specification sheet to ensure compatibility.
