Apologies if I'm confused, but why aren't you just using disposal bottle top filters? They work perfectly well under normal filtering conditions. Just be careful with the heat of the liquid you are filtering. There's a fine line - warmer (hotter) liquid of course filters quickly. I usually brewed everything to around 200F for between 20-30 minutes, let cool til no longer steaming, but still quite warm, then filtered using disposable bottle-top filters.
Worked for years through hundreds if not thousands of filtering sessions.
