SuperFilter 100 pcs, Disposable Filter, 3D Printer Resin and Paint Strainer, Made in Korea by 3DMaterials

Its a filter made of paper. It works well and functions as expected. They are the same size as typical filters. You may get a few uses out of them but they are intended as single use products, I wouldn't expect to get more than one use out of them but I'm happy when I do. They help clean up my vats, Hold up to the little chunks of plastic and are easy to poor into. I normally set one of these into a cheap funnel so I don't need to hold them open, and I don't need to worry about them collapsing when I do.

Good, no complaints. Does it what you bought it for without issue

These are perfect for doing fine filtering of paint for airbrushing. They are smaller, and the paper is not as thick as others I have used, but it is fine for a single-use product and works well.

Maybe not was it was intended for, but I used it for straining paint into my sprayer. The funnel is only about 2.5 inches tall therefore you can’t just pour all of the paint in making it a very slow roll. It did strain fairly well, but I will not be using it for painting projectsUPDATEI’m updating my review for this product because I feel my rating was in sufficient for the quality of the product. To be clear, the filter works very well. I was very pleased with its function. My only con was the size and that’s only in reference to my intended use. For smaller amounts of paints or resins, this is a great product.

These filters have been super handy for straining leftover resin after prints. They’re sturdy enough not to collapse or tear when pouring, and the mesh catches cured bits without slowing things down. I go through a lot of resin, so having 100 in the pack is a nice bonus. Definitely worth it if you want to keep your resin clean and your prints consistent.

Works as advertised. Much better imho than the funnels with metal grates for photopolymer resin. Metal grates get clogged with use, and personally I threw mine out after less than 100 use cycles. I bought the 4 inch plastic funnel below to rest the filter in:https://a.co/d/b0jOMiOAfter first use, it seems like the right size to me. Couldn’t find the white funnel that the other reviewer photographed in their comment.

I've used these conical strainers for decades, mostly for paint. But I used these to strain my expensive avocado cooking oil for reuse. This pack is quite a value.

Item was as described and shown; no surprises. Works fine for filtering resin reclaimed from the vat of my 3D printer.BT recommended
