I don’t think it will be as good as hydrophobic. For filtering the oil molecules would have to have be in contact with as much as possible of a surface. Using a hydrophilic filter will make the oil molecules to clump together like when you mix water and oil, and deceases the contact surface. I could be wrong though but this is my thought

A hydrophobic membrane, such as polytetrafluoroethylene (PTFE) will resist any aqueous sample, creating back pressure. Although it is sometimes possible to overcome this back pressure with additional force, there is a risk of membrane rupture and incomplete filtration.

Aqueous samples are unlikely to damage most membrane materials, particularly hydrophilic.

Since oleophobic membranes don't exist in order to have the effect you described, hydrophilic is fine and well all around

Just putting this out there as it seems like a good price for 12.

The people who can’t get it to hold, if suggest using more heat. My npp 200 has never crashed after brewing, and it’s probably 55-60F where I keep my gear

What % BA did you use for 200mg/mL NPP. Sounds perfect for my next cycle

Everything i Brew has either 1.5% or 2%.. If it is something that i will use up quickly or a small batch 1.5% id its a larger batch or something that may end up sitting for a year or 2 i use 2%..
