Protect your fermentation with this 3 piece airlock. Allow excess CO2 to escape while preventing harmful bacteria and wild yeast to enter. Simple insert into your fermenter lid or carboy bung or drilled stopper and fill sanitized water (or vodka) to the indicator line.
This 3PC plastic airlock is often preferred because of its low cost, and ease of disassembling for cleaning. It can also be hooked up to a blow off tube if you're expecting heavy fermentation. Grab a few!
