Excellent Quality Filtration Paper

As a result of using this filtration paper, I found that it consistently provides reliable filtration for a variety of lab experiments. The paper is also durable and resistant to tearing. However, it may require a longer filtration time compared to other papers. Overall, I highly recommend this product for its excellent quality and reliability.

Pros
  • Efficient filtration of laboratory samples
Cons
  • Not as durable as other filtration materials

maybe too strong?

These papers are well made, not flexible or stuffed in too small a box. These are NOT quick documents. My primary filtration has gone from 30 minutes to over 2 hours (8 liters). I'd say they're in the mid to slow range, not fast

Pros
  • Filtration
Cons
  • Slightly Crumpled

Perfect replacement for Melita No 1 disc filter, Krupps Moka beer

I first tried the 9cm Medium Flow (blue/white packaging) as a replacement filter in my old Krupps Moka brewery…. They worked but the flow rate was half that of the discontinued Melita No 1 disc filters and I was afraid of damaging the coffee maker over time because it filters coffee under pressure. Perfect! Almost the same speed as the discontinued Melita filter! Thanks very much!

Pros
  • Quality filter paper
Cons
  • not reliable
