Review on Midwest Homebrewing 🏠 and Winemaking Supplies FIL90 by Michael Staton

Allegedly "sanitary filter". However, it is not pre-sterilized (comes in a zip-lock pouch) and does not have a filter size listed on it. There is also no indication of what the body material is and whether it can be autoclaved (steam sterilized). So ideally you should have a 0.2 micron mesh PTFE vent filter to prevent microbial contamination of the gas or vent line to ensure "sanitation". Highlighting the word "sanitary" on the filter doesn't make it so.
