Our verdict

The Mfacoy Original Patented Airlock Fermentation Lids are the lightest pick at 0.24 lb and include a date tracker. The Masontops Pickle Pipes are the smallest in width at 0.5 in and height at 3.3 in, with a one piece waterless valve. The Easy Fermenter Fermentation Lids Kit is the heaviest at 0.64 lb and uses a plastic lid with a gasket. The JILLMO Stainless Steel Fermentation Lids are the only stainless steel option and include spare grommets. The Fermentaholics 2 Pack fits 110mm gallon jars, not wide mouth mason jars.

“Weight and jar fit decide before valve design does.”

Lush Editorial Team

What separates these five

Date tracking The Mfacoy lids include a date tracker so you can mark the start of each batch. The Xelyra lids also publish a date tracker, but Xelyra is not one of the five picks.
Published weight Mfacoy publishes 0.24 lb, JILLMO publishes 0.6 lb, Easy Fermenter publishes 0.64 lb, and Fermentaholics publishes 0.26 lb. Masontops does not publish a weight.
Jar fit Four picks fit wide mouth mason jars. The Fermentaholics 2 Pack fits standard 110mm gallon jars instead, so check your jar before buying.
Reusable materials Silicone, stainless steel, and plastic appear across the five picks. JILLMO and Xelyra use stainless steel lids, while Masontops, Mfacoy, and OAKDOLCHE use silicone.
Valve type All five picks publish a one way valve or airlock design. Masontops and Mfacoy use a waterless valve, while JILLMO and Fermentaholics use a separate airlock.

How we chose

Priorities, not a computed score. The inputs are published specifications, so we rank by what matters most and say how much.

  1. 30% Jar compatibilityThe lid must fit the jar you already own, so this is the first filter.
  2. 25% Published weightWeight is stated for four of the five picks and affects shipping and handling.
  3. 20% Valve designWaterless valves and airlocks change how much maintenance a batch needs.
  4. 15% Material and careSilicone, stainless steel, and plastic differ in dishwasher and washing instructions.
  5. 10% Date trackingA date tracker is a convenience feature, not a requirement for fermentation.

How the Five Compare on the Numbers

The five picks differ most clearly on published weight and jar fit. Mfacoy publishes 0.24 lb, Fermentaholics publishes 0.26 lb, JILLMO publishes 0.6 lb, and Easy Fermenter publishes 0.64 lb. Masontops does not publish a weight. On jar fit, four picks are made for wide mouth mason jars, while Fermentaholics is made for standard 110mm gallon jars.

Published dimensions are sparse. Masontops publishes a width of 0.5 in, a depth of 3.3 in, and a height of 3.3 in. Mfacoy publishes a width of 3.31 in, a depth of 3.31 in, and a height of 0.1 in. Easy Fermenter, JILLMO, and Fermentaholics do not publish width, depth, or height, so storage space cannot be compared for those three from the fact sheet alone.

The table does not tell you how any lid performs in use, because no one at Lush has used these machines and the manufacturers publish capability, not results. It also does not tell you the exact diameter of the Masontops, Mfacoy, or Easy Fermenter lids, because those figures are not published. The table only compares what the makers state.

How Jar Fit Narrows the Field

Wide mouth mason jars

Masontops, Mfacoy, Easy Fermenter, and JILLMO all publish a fit for wide mouth mason jars. JILLMO adds a range from 8 oz to 64 oz and a 3.38 inch 86 mm diameter. That range is the most specific jar fit published among the five picks. If you own several jar sizes, the JILLMO range is the only one that states a lower and upper limit.

Masontops, Mfacoy, and Easy Fermenter do not publish a jar size range. They state wide mouth only. A wide mouth mason jar is a common size, but the fact sheet does not give a diameter for these three, so you cannot confirm a fit from published figures alone. Check the jar thread before ordering.

Gallon jars

Fermentaholics publishes a fit for standard 110mm gallon jars and Fermentaholics gallon jars. That is a different jar class from the wide mouth mason jars the other four picks target. If your fermenting vessel is a gallon jar, this is the only pick on the sheet that states a fit for it.

The Fermentaholics pack includes a lid, a silicone gasket, a grommet, and an s airlock. The gasket is described as adhering to the lid and jar to create an airtight seal. The pack size is two lids and two airlocks, so it covers two jars. It will not fit a wide mouth mason jar.

How Valve Design and Materials Differ

Waterless valves and airlocks

Masontops and Mfacoy publish a one way waterless valve. Masontops describes it as a one piece airlock that requires no water, burping, or maintenance. Mfacoy describes a patented one way valve that vents carbon dioxide without manual burping or a water airlock. Both are self contained, with no separate airlock part to fit.

JILLMO and Fermentaholics publish a separate airlock. JILLMO includes BPA free airlocks and silicone grommets, and states that the airlock releases fermentation gas while limiting outside air exposure. Fermentaholics includes an s airlock and a rubber grommet. A separate airlock adds parts to assemble and clean, but the makers state it holds securely in the grommet.

Silicone, plastic, and stainless steel

Masontops, Mfacoy, and OAKDOLCHE publish silicone lids. Masontops states food safe silicone that is BPA free and free of phthalates. Mfacoy states 100 percent BPA free silicone that will not crack or warp. OAKDOLCHE states 100 percent food grade silicone. Silicone is flexible, which may matter if you want a lid that conforms to the jar rim.

Easy Fermenter publishes durable food safe plastic lids with a leak proof gasket. JILLMO publishes stainless steel lids with flexible silicone grommets and replaceable components. JILLMO also includes spare grommets and a 1 year replacement for damaged small parts. Stainless steel is rigid, while plastic and silicone are not. The makers do not publish a performance comparison between these materials.

Which One Fits Your Kitchen

Buyer who wants a date tracker. The Mfacoy lids are the only pick that publishes a date tracker. They weigh 0.24 lb and are made of BPA free silicone. If you run several batches and lose track of start dates, this is the pick that states the feature.

Buyer who wants a low profile silicone lid. Masontops publishes a width of 0.5 in and a height of 3.3 in, and the maker describes a low profile design for cupboard storage. The one piece waterless valve needs no water or burping. Weight is not published.

Buyer who prefers a plastic lid. Easy Fermenter publishes a four lid kit with a leak proof gasket and a plastic lid. It is the heaviest pick at 0.64 lb. Width, depth, and height are not published, so check your drawer space before ordering.

Buyer who wants stainless steel and spare parts. JILLMO publishes stainless steel lids, BPA free airlocks, silicone grommets, spare grommets, and a 1 year replacement for small parts. It fits wide mouth jars from 8 oz to 64 oz. The plastic airlocks should be washed with warm water only.

Buyer fermenting in a gallon jar. Fermentaholics publishes a two pack for standard 110mm gallon jars, with a lid, silicone gasket, grommet, and s airlock. It weighs 0.26 lb. It is not made for wide mouth mason jars, so buy it only if your vessel is a gallon jar.

Several figures are not published by the manufacturers, and we did not estimate them.

  • Masontops does not publish a weight for the Pickle Pipes.

  • JILLMO does not publish width, depth, or height for its stainless steel lids.
  • Fermentaholics does not publish width, depth, or height for its gallon jar lid.
  • Mfacoy does not publish a pack size in the features listed on the fact sheet.
  • Easy Fermenter does not publish dishwasher instructions in the features listed.

Frequently asked questions

Do all five picks fit wide mouth mason jars?+

Four of the five picks fit wide mouth mason jars: Masontops, Mfacoy, Easy Fermenter, and JILLMO. The Fermentaholics 2 Pack fits standard 110mm gallon jars and Fermentaholics gallon jars instead. Check the jar you plan to use before ordering, because a gallon jar lid will not seal a wide mouth mason jar.

Which pick is the lightest?+

Mfacoy publishes 0.24 lb, the lightest of the five picks. Fermentaholics publishes 0.26 lb, JILLMO publishes 0.6 lb, and Easy Fermenter publishes 0.64 lb. Masontops does not publish a weight, so it cannot be compared on this figure. Weight may matter if you plan to ship the lids or handle many jars at once.

Which pick has the smallest published width?+

Masontops publishes a width of 0.5 in, the smallest of the five picks. Mfacoy publishes 3.31 in. Easy Fermenter, JILLMO, and Fermentaholics do not publish a width. A smaller published width may mean the lid takes less space in a drawer, but the manufacturer does not state how the width is measured.

Do any picks include a date tracker?+

Mfacoy publishes a date tracker on its silicone pickle caps. None of the other four picks list a date tracker in their published features. A date tracker lets you mark the start of a ferment and keep multiple jars organized. If you run several batches at once, this is the only pick on the sheet that states the feature.

Which picks use stainless steel lids?+

JILLMO publishes stainless steel fermentation lids with seals, BPA free airlocks, and silicone grommets. Xelyra also publishes stainless steel lids, but Xelyra is not one of the five picks. Masontops, Mfacoy, and OAKDOLCHE publish silicone lids. Easy Fermenter publishes plastic lids. Stainless steel may suit buyers who prefer a rigid lid.

Can I put these lids in the dishwasher?+

Masontops, Mfacoy, Fermentaholics, and OAKDOLCHE publish dishwasher safe materials. JILLMO states that the plastic airlocks should be washed with warm water only and not boiled, so check the care instructions for each part. Easy Fermenter does not publish dishwasher instructions in the features listed on the fact sheet.
