Cant find ptfe bottle tops easily

[OldmemberNewcuenta]

Just searching for options for these, it doesn't seem to be available in abundance. Most of what I'm seeing is PES bottle top filters.
But it looks as though many are using PES bottle top filters for filtering their oils.
Is it really of not issue to filter oils withe 1.5-2% Ba and 20% bb? I thought they would melt the pes filters?

Bro I wish I was a better help just trying to add traction to your post. I get rather irritated with the various yes and no abilities of these filters. one minute im told its fine as long as it the correct type hydrophobic vs hydrophilic that various membranes are in theory safe. Then im told the opposite and it has to be x type for the ba and bb
