You're probably looking at http://www.amazon.de/Keramikfilter-Wasserfilter-NEU-Filter-Feinfilter/dp/B002RLKE7O/
or http://www.amazon.de/Keramikfilter-Kartusche-Wasserfilter-Partikelfilter-Filterkerze/dp/B00AAV53O2/

How do you know the plastic parts would not warp
and cause leaks?

Also, this is just the filter cartridge, you'd need to sterilize
the whole assembly.

At volumes of 30+ liters, that's the least of my worry.
