I don't use the airlock on mine. It lets more oxygen in to get the yeasts going quicker and gives a cleaner primary ferment. It will work, but I jus don't use it for the reason I stated. I just lay a washcloth or similar over the hole. I have tried just a cheesecloth over the top, but things can get knocked in it that way accidentally.
We use a cotton dish towel over the top of the bucket, attached with string and rubber band. Then we set the cover on top to keep the cats from falling through.

On one kit, I decided to snap the lid down tightly on the fermenter and leave an airlock in place. Needelss to say, when I checked it next, the lid was holding a dome shape and the airlock was going crazy. Since then, I use an airlock in the hole and just set the lid in place just like smurfe stated.
