### ⭐⭐⭐⭐⭐ Need careful separation
*by W***O on 10 October 2025*

### ⭐⭐⭐⭐⭐ Paper filter

It’s a filter and it’s made of paper

### ⭐⭐⭐⭐⭐ Review
*by J***E on 10 May 2021*

Saves me a ton of time and hassle having to cut filters for my Closed Loop extractor. The 75mm is perfect for tri clamp sanitary 3” spools to fit in the gasket without overlapping the Center ring of the gasket, allowing the filter to be clamped in the gasket so it doesn’t move during extraction or have product pass by without being filtered. All in all a great purchase, high quality, low box design to save you a few extra dollars. Even the company name fits in with BHO extraction almost haha Stony lab! Keep up the great work! If you do BHO as well then this is the stuff to get, the quantitive contains Ash and it will contaminate the product return.
