Short answer: If you already own a FoodSaver bag sealer with an accessory port, the FoodSaver FCARWJAH-000 jar sealer kit is the simplest way to vacuum mason jars: it is a jar sealer and hose that plug into the machine you have. If you want a standalone cordless jar sealer, start with the Mason Genie MG1, whose listing states regular and wide-mouth fit, ten lids, a lid opener and USB-C charging. Choose the Roboseal by Emson if you want the most lids in the box.

We did not seal jars with these tools. Specs come from each product’s listing and are named in our source notes; anything a listing leaves out is marked “not listed.” Method: How We Review.

Safety note: vacuum sealing a jar is not canning. A jar under vacuum is not shelf-stable, and these tools do not replace refrigeration, freezing or a research-based canning process. Several listings use the words “canning” or promise food lasts several times longer; we do not repeat those claims. For what can be stored and how, follow the National Center for Home Food Preservation and the USDA Food Safety and Inspection Service. Use only the jars, lids and adapters each manual names, and charge battery units with the cable supplied. Check the brand at cpsc.gov/Recalls before buying.

Quick Comparison

How We Chose

A mason jar vacuum sealer pulls air out of a jar through a special lid or a lid placed under a sealing cap. There are two kinds: accessories that connect to a bag sealer’s accessory port by a hose, and small battery units that sit on the lid. What matters is which jar mouths it fits, whether lids come with it, how it is powered, whether it stops on its own, and what the maker promises if it fails.

Each product had to be sold new on Amazon on November 10, 2026, and in stock with a named seller when we rechecked the listings on November 14, 2026. Its listing had to state the jar sizes it fits. We searched CPSC records for each brand and found no jar sealer recall.

We did not use price, ratings, review counts or sales rank. Suction claims (kPa) and freshness multipliers are not comparable across these listings, and we leave the freshness numbers out entirely.

The 5 Best Vacuum Sealers for Mason Jars

1. FoodSaver FCARWJAH-000 Jar Sealer Kit: Best for FoodSaver Owners

Check price on Amazon

It earns the label because it uses the pump you already own. If your FoodSaver has an accessory port, like the FM2100 in our vacuum sealer guide, this adds jar sealing without another battery device on the counter.

It does nothing without a compatible machine, and the listing is unclear on whether one sealer covers both jar sizes or only wide mouth. FoodSaver also sells separate regular and wide-mouth jar sealers. Check the box contents on the product page.

Pros

• Uses your existing FoodSaver’s pump
• Dishwasher safe
• No battery to charge

Cons

• Requires a FoodSaver with an accessory port
• Jar size coverage unclear on the listing
• No warranty term stated

Good fit if

• You own a FoodSaver with an accessory port
• You want fewer gadgets

Skip if

• You do not own a compatible bag sealer
• You want lids included

Verdict: The obvious add-on for existing FoodSaver owners.

2. Mason Genie MG1: Best Standalone Kit

Check price on Amazon

It earns the label by putting together everything a first-time jar sealer needs: both mouth sizes, ten lids you can label, a tool to break the seal, and USB-C charging. The listing says it holds charge for dozens of seals.

The listing is inconsistent on lids: one line says no special lids are needed, another lists the included vacuum lids. Use the lids the manual names. The only promise stated is a 30-day money-back guarantee. On November 14, 2026, it was in stock and sold by Mason Genie, the brand’s own store.

Pros

• Both jar sizes plus 10 lids
• Lid opener included
• USB-C charging

Cons

• No warranty beyond 30-day money-back
• Lid requirements stated two ways
• Sold only by the brand’s store

Good fit if

• You want a complete starter kit
• You like labeling pantry jars

Skip if

• You want a written warranty
• You already own a FoodSaver with a port

Verdict: The most complete starter kit, with thin warranty terms.

3. Roboseal by Emson 4664: Best Lid Count

Check price on Amazon

Fifty lids earn the label, five times what the other kits include. It is also the only standalone unit here that states both an auto stop and a battery indicator, and it names the jar range it fits.

One bullet heading calls it a “10-lid kit” while the title and contents list 50 lids, so check the bundle you select. The listing gives no warranty term. On November 14, 2026, it was in stock and sold by Amazon.com.

Pros

• 50 lids included
• Auto stop and battery indicator
• States jar range (8 to 32 oz)

Cons

• Lid count stated two ways in the listing
• No warranty term
• Bundle options differ; check the one you select

Good fit if

• You seal many jars at once
• You want to see battery level

Skip if

• You want a written warranty
• You only seal a few jars

Verdict: The most lids and the clearest controls on paper.

4. Plateful VacuFresh: Best Stated Jar Fit

Check price on Amazon

It earns the label as the only listing that gives the actual mouth diameters it fits, which helps if your jars are not a common brand. It is also the only standalone unit with full dimensions stated.

It does not state an auto stop or warranty. On November 14, 2026, it was in stock and sold by TryPlateful, the brand’s store. The listing calls it a “dry canning” tool; we do not, for the reasons in the safety note.

Pros

• Mouth diameters stated
• Full dimensions and weight stated
• 10 lids included

Cons

• No warranty term
• Auto stop not stated
• Sold only by the brand’s store

Good fit if

• Your jars are an unusual brand and you want to check fit
• You want a compact cordless unit

Skip if

• You want a stated auto stop
• You want warranty terms

Verdict: The best-documented fit for odd jars.

5. UNERVER M11: Best Stated Warranty

Check price on Amazon

A stated 12-month warranty earns the label: it is the only standalone jar sealer here with a written warranty term. It includes lids for both jar sizes plus labels.

The power fields contradict each other and the 230 V figure does not match US outlets, so confirm the power source and charger on the product page before buying. On November 14, 2026, it was in stock and sold by the brand’s store, UNERVER Chief Direct Shop.

Pros

• 12-month warranty stated
• Both jar sizes plus labels
• Compact

Cons

• Power source and voltage fields conflict
• Auto stop not stated
• Sold only by the brand’s store

Good fit if

• A written warranty matters most to you
• You want labels in the box

Skip if

• You want clear power specs
• You want the most lids

Verdict: The only stated warranty among the cordless units, with messy specs.

What Each Spec Changes

Accessory or standalone. An accessory like the FoodSaver kit uses your bag sealer’s pump through a hose. A standalone unit has its own small pump and battery. If you already own a sealer with a port, the accessory avoids another device to charge.

Jar mouth sizes. Regular and wide-mouth jars need different lids or an adapter. Every product here claims both, though the FoodSaver listing is unclear. Only Plateful states the diameters.

Included lids. Standalone units work with the vacuum lids their makers include. Counts here run from 10 to 50.

Auto stop. Only Roboseal states that it stops on its own when the jar is sealed. Others describe one-touch operation without saying when the pump stops.

Suction figures. Some jar sealer listings quote kPa; none of the five here gives a figure we could compare, and a kPa number alone does not tell you how long a jar holds vacuum.

Warranty. UNERVER states 12 months. Mason Genie offers a 30-day money-back guarantee. The rest give no term.

Who Should Not Buy a Mason Jar Vacuum Sealer

• Anyone hoping to store low-acid food at room temperature in a jar. That requires a research-based canning process; see NCHFP.
• People who mainly freeze meat or bulk food in bags. A bag sealer is the better tool: see our vacuum sealer guide and vacuum sealers for meat.
• Cooks who want a cordless bag option rather than jars; see our Chef Preserve review.

FAQ

Is vacuum sealing a jar the same as canning? No. Vacuum sealing only removes air from the jar; it is not a canning process. Follow NCHFP for canning.

Do I need special lids? The cordless units here include their own vacuum lids. The FoodSaver accessory is listed for mason-type jars; check its manual for which lids it works with.

Can a regular FoodSaver seal jars? Only with an accessory port and a jar sealer attachment like the FCARWJAH-000.

How long does food last in a vacuum-sealed jar? We do not give storage times. Use USDA and NCHFP guidance for the specific food.
