Review: Good quality and reasonable price! - On-time, good quality, reasonable price, and served the purpose. My only recommendation is for the package to include the pore size information. The package does not include the pore size, I obviously know the pore size I bought but since the package doesn't mention it I have to trust they sent it correctly. I would have liked to see it printed somewhere on the box. Also because we have many paper filters at the lab and is easy to get confused. Although I label it myself to avoid future confusion.
