Forum shows conflicting results: Hydrophillic or Hydrophobic filter?

[ThiccManJack]

I've been looking through the forum, and have seen conflicting reports with some people claiming hydrophillic is the best for filtering oils, and others claiming hydrophobic, with each side arguing with the other. I've been using hydrophillic for reference (as it seemed to be standard). Here's some of the threads I've looked at so far relating to this question:

hydrophobic or hydrophilic? what do you use?

Hi All, Hydrophobic or Hydrophilic? which type of filter do you use/prefer? why? I'm planning to buy PTFE 0.2um & 0.45um sterile membranes. Which should I go for hydrophobic or hydrophilic? Thank you!

Glass filtration setup or bottle top?

New to using anything other than syringe filters. I bought glass media bottles and Nalgene Bottle Top filters (Nalgene™ Rapid-Flow™ Sterile Single Use Vacuum Filter Units) (0.2um Nylon) however it seems to really slow down after 100ml and it starts cracking and I am certain it is letting oil...

Buncher filter is very slow- help

First time brewed, but I need some help with filtering it. Filtered with buncher funnel with 0.22micron 47mm membran filter but filtering process so slow like 50ml/35min, and changing filter paper every 50ml. I put liquid in 50celcius warm for faster filtration. Sterilizing; Washed glassware...

PES and BA

Is a PES filter fine to use with a low amount (10ml) of a 0.9% BA solution??

PVDF Vacuum Filter setup

Ok, so I use 47mm .22um PVDF filters for filtering oil with a sintered glass lab apparatus. Sterilize them before use, yada yada. There are at least two different filter versions; a hydrophobic and hydrophilic version. It seems to take forever to filter 100ml, and I'm wondering if the...

What's your opinion?

This is an opinion brother, but it's also a fact. Although I normally don't say stuff like this on this forum because people like to argue. However I can tell you for certain, there is no doubt about it, that hydrophobic PVDF, or PTFE membranes will work best for filtration. You can use a hydrophilic Nylon or hydrophillic PVDF, but you will be like other guys who complain about filtering 100ml and 45 minutes.

Wrong syringe filters?

I just answered this in another thread. It’s very simple. Hydrophobic for oil-based, hydrophilic for water-based solutions.
