Ok so the mushroom shaped part is porus then ?
Not exactly porous but about half-right. Look at the the glass 'dildo' picture. You see the rough surface? That's the filter. When you put it in place, the rough surface sits tight with the smooth surface to form a porous surface. Super simple but works ridiculously well. It's better than most filter and only let through a tiny bit more grind than paper/cloth filter. The thing to note is never ever disturb it during the process (especially stirring) or grind may find its way into the bottom globe. Used correctly, the level of the grind in the cup is similar to aeropress with the fine metal disk filter. Also, I find that I can use effectively finer than drip grind and still get good result. Of course I need to steep less to compensate for faster extraction. If you don't have a good brew grinder, you have to grind finer to prevent the filter from clogging, not coarser. That's counterintuitive, but the cheaper grinder produces more fines at coarse grind, and less at finer range.
