Alright now everyone has tried the whatman filters.... kinda slow and semi sh1tty but whatever right.... now the bottle top filters are a step up from there but I tried them and I went through a whole lot of them... I cracked a bunch and then the filters ripped on a few more and so on and so on... it was a f@cking nightmare guys!!! and I still have a bunch of unfiltered test... well needlessly said I am unhappy with any of the filtering systems that I am aware of... .what is the next step up??? I plan on doing this for the next 30 years or so... so in the long run it is worth the investment to buy something that can actually DO THE DAMN JOB!!!! some kind of pump or machine or what??? I know there is something cuz QV and Denkall sure as hell don't sit down with bottle top filters!!! (they probably don't filter at all!!!) haha.... no really though.... let's get an answer here!
