Sous vide asks more of a bag than freezer storage does. The seal has to survive hours in hot water, the bag has to stay sunk so the food cooks evenly, and the sealer has to cope with marinades, butter and juicy proteins without sucking them into the seal strip. The best vacuum sealer for sous vide gets all three right.
Three features matter most: a wet-food mode or pulse control so you can stop before juice reaches the seal, a double or wide seal for long cooks, and bags rated for cooking temperatures. Below are six picks across external, chamber and handheld designs, then a buying guide and a section on sous vide bags.

Chamber vs external: how each one pulls the air
The pump empties the whole chamber, so pressure falls inside and outside the pouch at the same rate. Nothing is pushed toward the opening, which is why liquids stay in the pouch.
The pump pulls air out through the bag mouth along the embossed channels. Outside air keeps pressing on the bag, and any liquid travels with the air toward the seal.
Schematic, not to scale. Under deep chamber vacuum, warm liquids boil, so chill soups and marinades before sealing. External sealers need embossed bags; chamber sealers use smooth pouches.
The best vacuum sealers for sous vide, reviewed
1. Anova Precision Vacuum Sealer Pro: Best Overall
Who it's for: people who cook sous vide every week and want a countertop sealer built around that habit.
Anova makes sous vide circulators, and its Pro sealer reads like it was designed by people who bag a lot of steaks. Anova lists a double sealer, a moist preset for wet food, and pulse control so you can stop the vacuum before a fish fillet flattens or juice creeps to the strip. Built-in roll storage and a cutter let you size bags to a rack of ribs or a single chicken breast. An accessory port with an included hose handles containers, jar lids and wine bottles.
Anova lists 110 W, an extraction rate of 12 L/min, a footprint of 14.75 x 7 x 4.3 in., and a 2-year warranty with a 100-day money-back guarantee. It is still an external sealer, so true liquids (a cup of stock, a bag of curry) need freezing first. For everything else in a sous vide routine, it is the most complete package here. If you already own an Anova cooker, our Anova chamber sealer review compares it with Anova's chamber model.
Pros
- Double seal for long water baths
- Moist preset and pulse control
- Roll storage, cutter and accessory hose
- 2-year warranty
Cons
- Not for soups or brines without pre-freezing
- Weight not published

2. Anova Precision Chamber Vacuum Sealer: Best Chamber for Sous Vide
Who it's for: cooks who want to seal sauces, brines and butter-basted proteins directly, and who are curious about compression and infusion.
A chamber sealer changes what you can put in a sous vide bag. Because air leaves the whole chamber, a short rib with braising liquid or salmon with a spoonful of miso glaze stays in the pouch. Anova lists a 70 L/min dry pump, -0.95 bar of vacuum, an 11.8 in. seal bar and a 12 x 8.6 x 3 in. chamber. Presets cover Infuse/Extract, Compress/Pickle and Dry/Cool, plus manual control of vacuum and seal strength.
The outer size is 13.6 x 11.2 x 8.9 in., compact for a chamber machine, and the warranty is 2 years. The 3 in. chamber height limits thick roasts, and you will need smooth chamber pouches that fit the chamber. For the full rundown, see our Anova Precision Chamber Vacuum Sealer review.
Pros
- Seals liquids and marinades in one step
- Infusion, compression and pickling presets
- Dry pump, no oil
- Compact for a chamber sealer
Cons
- 3 in. chamber height
- Pouch size limited by the chamber
- Weight not published

3. Avid Armor USV20: Best for Marinades and Sauces
Who it's for: batch cooks who seal wet portions for the water bath and freezer, and want manual control over every cycle.
Where Anova leans on presets, the USV20 gives you timers. Avid Armor lists a vacuum time adjustable from 15 to 60 seconds and a seal time from 3 to 9 seconds, so you can pull hard on a dense pork shoulder and stop early on a delicate marinade, then repeat the exact cycle across a batch. The 11.5 in. seal bar takes pouches up to 11 x 10 in., wide enough for two steaks side by side. A marinate function, an accessory port with hose, a pouch clamp and a tempered glass lid are included, and the dry rocker pump needs no oil.
Avid Armor says the lid stands 17 in. tall when fully open, so it opens under most upper cabinets. The chamber is molded plastic and about 3 in. tall, so it suits portions rather than whole briskets. Avid Armor also rates its chamber pouches as freezer, boil and sous vide safe. Our best chamber vacuum sealers guide puts it against bigger machines.
Pros
- Timed vacuum and seal control
- Handles marinades and sauces directly
- Dry pump; opens under standard cabinets
Cons
- Plastic chamber, about 3 in. tall
- Pouches limited to 11 x 10 in.
- 1-year warranty

4. Nesco VS-12 Deluxe: Best Value
Who it's for: home cooks who sous vide a couple of times a week and also stock the freezer.
The VS-12 is a general-purpose sealer with the settings sous vide needs. Nesco's care guide describes Dry and Moist seal settings (Moist uses a longer heat time for damp food), a Gentle pressure setting for soft food, a pulse vacuum button, and a Manual Seal button that stops the pump and seals immediately when you are happy with the vacuum. That last button is the sous vide trick: watch a marinated chicken thigh and seal before juice reaches the strip. Nesco lists a 130 W, 25.1 inHg double vacuum pump, bag storage for one 11 in. roll, and a built-in cutter.
The limits are a 1-year warranty and a duty cycle the manual sets at one operating cycle every two minutes, so it is not built for marathon batch days. Our Nesco VS-12 Deluxe review covers it in depth.
Pros
- Moist setting, Gentle pressure and pulse
- Manual Seal button to stop the vacuum early
- Roll storage and cutter; works with any brand of bag
Cons
- One cycle every two minutes, per the manual
- 1-year warranty

5. Anova Precision Vacuum Sealer: Best Budget
Who it's for: occasional sous vide cooks who want a sealer that fits in a drawer.
Anova's original slim sealer is about as simple as a heat-sealing machine gets. It has three buttons (vacuum and seal, seal only, and pulse vacuum), weighs 2.3 lb, and measures 16.73 x 4.80 x 3.14 in., per Anova. The pulse button lets you stop before delicate food is crushed, and the seal-only button closes the bottom of a bag cut from a roll.
Anova lists -0.5 bar of vacuum and a 4 L/min extraction rate, far below the Pro's, and there is no roll storage, cutter or double seal. For a few steaks a week it is enough. It ships with 10 pre-cut bags and a 2-year warranty.
Pros
- Very light and easy to store
- Pulse vacuum control
- 2-year warranty
Cons
- Weaker vacuum than the Pro
- No roll storage, cutter or double seal

6. ZWILLING Fresh & Save Pump and Bag Set: Best Reusable Bags
Who it's for: cooks who want to stop throwing away a plastic bag after every cook, and who mostly cook below about 190 °F.
ZWILLING's system pairs a rechargeable handheld pump with zip bags that have a valve. The pump charges by USB and stops automatically once it reaches enough vacuum. ZWILLING markets the bags for sous vide and lists heat resistance to 197.60 °F (92 °C) and cold resistance to -0.40 °F (-18 °C), which covers steak, chicken, fish and most vegetables. The S/M/L starter set includes the pump, three bags, an adapter, a USB cable, a liquid barrier and a zipper slider.
There is no heat seal, so you rely on a zip closure in a long water bath. That suits weeknight cooks better than 48-hour short ribs. Bags are freezer-safe, and ZWILLING says they are microwave-safe only without the vacuum seal.
Pros
- Reusable, BPA-free bags with a published heat rating
- Cordless, USB-rechargeable pump
- Doubles as a fridge storage system
Cons
- No heat seal
- Bags are proprietary
- Not for cooks near boiling temperatures

Buying guide: how to choose a sous vide vacuum sealer
External or chamber?
An external sealer is enough for most sous vide: steaks, chicken, pork chops, fish, vegetables with a little butter. Pick a chamber sealer if your recipes regularly put liquid in the bag (braising liquid, brine, a generous marinade) or if you want compression and infusion tricks. Our guide to vacuum sealing liquids explains the freeze-first workaround for external sealers.
Wet-food control
The single most useful feature on an external sealer is a way to stop the vacuum early. Look for a moist mode, a gentle or low-pressure setting, a pulse button, or a "seal now" button. The Nesco VS-12, the Anova Pro and the Anova slim all have at least one of these.
Seal quality
Long cooks stress the seal. A double seal, or two seal lines placed a little apart, gives you a backup if one line has a wrinkle or a film of fat. Chamber machines with a wide seal bar and adjustable seal time do the same job.
Bag width and roll storage
Roll storage with a built-in cutter lets you make a long bag for a rack of ribs or a short one for a single portion. On chamber sealers, the seal bar and chamber depth cap the pouch size: 11 x 10 in. on the USV20, for example.
Reusable or disposable bags
Reusable valve bags cut waste but give up the heat seal. Heat-sealed bags are single-use in most kitchens, especially after raw meat.
Sous vide bags: what to buy and how to use them
- Check the heat rating. Use bags their maker rates for cooking, boiling or sous vide. ZWILLING publishes a 197.60 °F limit for its bags, and Avid Armor rates its chamber pouches as boil and sous vide safe. For other brands, check the box or listing.
- Embossed bags for external sealers, smooth pouches for chambers. External sealers need embossed or channeled bags. Chamber sealers use cheaper smooth pouches. See our chamber vacuum sealer bags guide for sizes and thickness.
- Leave headspace. Nesco's care guide suggests leaving about 3 in. at the open end so the bag sits properly in the sealer.
- Chill or freeze wet additions. Cold butter and frozen marinade cubes seal cleanly in an external sealer.
- Cushion bones. Nesco warns that sharp points such as fish bones can pierce bags. Wrap bone ends in a folded paper towel.
- Keep bags sunk. If a bag floats, clip it to the container wall or use a weight so it stays fully under water.
Food safety for sous vide
Vacuum sealing removes air. It does not make raw food safer, and low-oxygen packages need care:
- Keep sealed raw food cold. Store bagged raw protein at 40 °F or below, as USDA FSIS advises for all perishables, and cook it within the normal refrigerator window for that food. Clemson Cooperative Extension (HGIC 3865) warns that Clostridium botulinum can grow in low-acid, moist foods in a low-oxygen environment at room temperature, and FDA's reduced-oxygen packaging guidance for fish notes that some strains grow at 38 °F and above.
- Cook to a safe result. USDA FSIS lists safe minimum internal temperatures (for example, 165 °F for poultry and 145 °F with a 3-minute rest for whole cuts of beef, pork, veal and lamb). Lower sous vide temperatures depend on long holding times; follow a recipe from a reputable source and use an accurate cooker.
- Chill what you will not serve. If you cook ahead, move bags into an ice-water bath and then the fridge or freezer. FSIS advises refrigerating cooked food within 2 hours.

How we chose
We did not test these sealers. We compared current US models using manufacturer product pages, care and use guides and official retail listings, focusing on the features that matter for sous vide: wet-food control, seal strength, bag storage, and bag heat ratings. We favored brands that sell replacement parts and publish warranty terms, and we left out specs we could not confirm from a manufacturer or retailer.
FAQ
Do you need a vacuum sealer for sous vide?
No. Zip-top freezer bags sealed with the water displacement method work for short cooks. A vacuum sealer pays off when you cook often, cook for many hours, batch-cook for the freezer, or want bags that stay sunk without clips.
What kind of vacuum sealer is best for sous vide?
An external sealer with a moist or pulse mode and a double seal handles most sous vide cooking. A chamber sealer is better if you often bag marinades, sauces, butter-basted proteins or brines, because liquid stays in the bag.
Are sous vide bags safe at high temperatures?
Use bags rated for sous vide or boiling by their maker. For example, ZWILLING lists its Fresh & Save bags as heat-resistant to 197.6 °F, and Avid Armor rates its chamber pouches as boil and sous vide safe. Check the rating before long, hot cooks.
Can I use FoodSaver or Nesco bags for sous vide?
Embossed vacuum sealer bags from the major brands are widely used for sous vide. Check the box or listing for a cooking or simmering rating, use a double seal, and avoid long cooks near boiling unless the bag is rated for it.
Why do my sous vide bags float?
Trapped air or gas released by the food. A stronger vacuum, a pulse-controlled finish for delicate food, and a double seal help. For bags that still float, clip them to the container or add a sous vide weight.
Verdict
The Anova Precision Vacuum Sealer Pro is the best vacuum sealer for sous vide for most cooks: double seal, moist mode, pulse control and roll storage in a compact body. If your bags often hold sauce or brine, step up to a chamber machine, the Anova Precision Chamber Vacuum Sealer for presets or the Avid Armor USV20 for timed control. On a tight budget, the Nesco VS-12 Deluxe covers sous vide and the freezer.
