check out this filter

Quest is a company the orginated in Vancouver, BC.
If I remember right the filter was called a Fire Guard or something like that.
I believe they were developed by a guy name Dave Russell. One of the owners of Quest and Russell Foods
Those filters are great to clean. But watch the edges of the baffles - they are sharp.
Quest also make, what I think, is the best water wash hood to clean. It is ACCESSIBLE.
 
I noticed on the same website that they carry an entire line of disposable grease exhaust filters.

If these have never been legal to use, how can they still sell them?

NFPA can't make a single thing legal or illegal. They can only make suggestions and recommendations to the AHJ.

Prism(SC Johnson) still sells their wonder filter.

Did a post get deleted? I did not see any post as to the legality of the filters. Legality is not determined by NFPA, UL or UL-C. Legality is determined by a goverment agency. A government agency may adopt a standard as law, or it may notor may adopt parts of a standard. (Oregon has done that ) If a government agency does adopt a standard as law, any subsequent revision may or may not be adopted as law. To further compoind the confusion, other model codes, such as International Building Codes may also refer to other codes, referencing them as standards. IBC references NFPA 10, which refers to NFPA 96. However, IBC does not direclty reference NFPA 96. Instead, IBC has a different set of codes for exhaust systems which are not a strict or thorough as NFPA 96. Aluminum filters do not meet NFPA standards, but are still sold.

When refering to legality of certain supplies or job processes, be carefull. What is law in one area of jurisdiction, may not be law in another jurisdiction. For instance in California, NFPA 96 is law, or soon will be because California has adopted NFPA 5000, a model buildng code. I do not know when NFPA 5000 is to go into effect. And now, because of the new Gov, that decision may be recinded and the IBC may be legislated into law.

Disposable filters should be disposed of, they are junk and overpriced. Mesh filters the same, they are not permitted in most jurisdictions but we still find them and they pose a bigger danger than no filters. Aluminum are not so bad in certain applications but still not permitted in some areas also. Stainless steel and galvanized are the way to go.
