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.

Works well and is cheap.
If you want to keep a shipshape home brewing operation, the 3-piece airlock is the only way to go. It's a cinch to take these apart and clean them thoroughly. My advice is to get several, so if one goes bad, you can turn to your spare airlocks with ease.
