Personally no luck with Millipore,
Grandpa Gains/ Iron Vett
Having similar isues I moved away from Millipore to using 1. Fox Life AutoFill PP Funnel .45 High Flow PTFE prefilter
2. Zap Cap CR Nylon .2um polypropylene as final filtration. 2 benefits decrease filtration time, 2nd clearest , smoothest gear i have ever brewed. My brew recipes are fairly basic 2% Ba 15%-20 BB. Weather it was my novice mistakes with Millipore I am not sure. 25 brews since using my 2 stage system results have been excellent, that comment comes from others. All product have come from ST, all have been passed melt point test perfectly.
