Hi all
I've been on the hunt for reasonably priced oxygen cylinders for a while now in my quest to oxygenate my wort properly - nothing available in my budget.
John Palmer suggests a cheap aquarium pump with an in-line HEPA filter.
But now I have managed to source a local manufacturer, I don't know which type of HEPA to get from these:
Any thoughts/recommendations

- Polyethersulphone (PES)
- Mixed Cellulose Ester (MCE)
- Nylon
Any thoughts/recommendations
