Well priced

Although I needed to shim with cardboard to get a snuggle fit they seem well made, the factory filters are so expensive and in my shop environment with the dust they are clogged within a month so these are a godsend!

The filters you sent are clearly lower quality than the ones I typically use. Thin, fewer heavy duty folds etc. Really cheap product and I was hopeful you could be my ongoing supplier rather than a one time fix. Too bad!
