The 3-Piece airlock is the best choice for the primary fermenter, since it comes apart for easy cleaning in the event of a blow-off.
Fill to the line with boiled water or sanitizer to create a closed fermenting system that allows CO2 to escape, but does not allow air back in to contaminate your beer or wine.

Wow, this airlock was really excellent, the plastic was so smooth, and it "locked the air in" just right!!! You definitely want to get your hands on some of these 3 pieced airlocks! When they request a review for the airlocks make sure you share how awesome they are!!!! :-)
these seems to work best then the other basic one. thank you
Airlock 3-Piece Type
only downside is it turns into a fruitfly trap so better have a few extra locks on hand to swap in with a clean one
Easy to use airlock, just mind the fill line, works like a charm. Just sanitize it when you are ready to ferment!
