QUOTE(ozak @ Nov 26 2025, 01:15 PM) Not membrane filter. Copy the copycat and claim invent, memang muka tebal lvl9000.Inside is consist of fiber (filter to 0.1u), activated charcoal and some others filter. Depending on the price. This thing is invent by Danish. Copy by China and "cipta" by UITM?  Anyway, I've been using this for 8 years called Sawyer.  I wonder how much research grant they applied and where they spend all of it... gobiomani liked this post
