Filters question for PPB

[formernuke]

Ok so I'm pretty sure I've picked out my compressor.

My tanks are O2 clean

For now I'm not going to blend nitrox, remember even a year ago I swore I would not have a high pressure air system in my house so Subject to change. However the shops around here all use partial pressure blending. All the compressors have filters to grade E air but not filtered to maintain O2 clean.

So what additional filters do I need to maintain O2 clean?

first off continuous mix and skip the shops and o2 cleaning altogether

Just run 2 normal triplex filters

change the first when the humidity in the gas stream is >20%
change the second on rated time/volume or at 1 year whichever is sooner.
