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.

My son is taking chemistry this fall at home. These filters are a good quality and the price is very good for 50. They are packaged well in a top closing plastic box. They are a bit smaller than his chemistry book recommends but I think they'll work just fine. They are 2 inches across. Overall for the quality and price, I can definitely recommend these!

I recently purchased these PTFE Membrane Disc Filters, and they've been great cost/value/performance wise. So far, they perform just as well as the ones I got from Sigma. If you've never used them -- these filters have a hydrophobic nature that makes them ideal for filtering gases, and the 0.22ยตm pore size ensures that they effectively trap bacteria and other particles. The 47mm diameter is also ideal for large-volume filtration, making them versatile and useful for a variety of applications. Good value for money on these filters. They're competitively priced, and I'm satisfied with the quality. They've held up well under pressure, and I haven't had any issues with leaks or poor filtration. Definitely a good purchase 5 stars
