If you are using the .5 micron ones they are a bit fine for what we are doing, I tend to go with the 2 micron ones by preference. The finer ones I only use for nitrogen charging, porters and stouts.

Thanks doc, yeah I have the 2 micron ones too. I have some 93% neutral here. Might have to try that instead of azeo.
