# Best Airlock Lids Source: https://fermentnest.com/best/best-airlock-lids Updated: 2026-10-06 Publisher: Ferment Nest. Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://fermentnest.com/how-we-research#our-score An airlock lid lets carbon dioxide leave the jar without letting air back in, so you can ferment without burping lids twice a day. Designs split into three-piece water airlocks, silicone nipple valves, and simple one-way domes. They differ in how much brine can wick out, how firmly the seal grips the jar threads, and whether the valve still opens once brine has dried inside it and gone sticky. We weighed seal reliability first, then cleanability, since a valve you cannot rinse properly becomes a permanent smell. Water airlocks give clear visual proof of activity and suit longer ferments, though the reservoir needs topping up. Silicone valves are lower maintenance and pack better into a crowded fridge or cupboard. If you ferment in both jar sizes, look for a set that includes regular and wide mouth lids together. ## Picks ### 1.
