FoodSaver V4440 vs Anova Sealer Pro: which edge sealer to buy

Only one of these two sealers has been put on a gauge. Shouldit measured the Anova Precision Vacuum Sealer Pro at 68 kPa in a 36 second cycle on its review page (its comparison page lists a 14 second dry cycle) and ran one bag of beef through a water bath in moist mode without a leak (E·09, E·10, E·12). For the FoodSaver V4440 we found no suction reading, no timed cycle and no bath result, from anyone (E·27). That lopsidedness is the first thing to know, and it shapes everything below. One machine has a thin measured record. The other has a long feature list, a frank manual and a warranty.

What the two share is bigger. Both are external suction sealers, both pull air through the mouth of the bag, and neither maker offers a liquid mode: Anova says to avoid liquids in the bag and FoodSaver says to freeze them first (E·04, E·22). So the real decision runs through smaller things: whether you want a sensor or a button to start a cycle, how you want to protect soft food, and which built-in tools you will use.

We read both makers' pages and the manual FoodSaver files for the V4440 (V4400 Series), Shouldit's instrumented test and comparison page, America's Test Kitchen's verdict, The Gadgeteer, owner threads on both sides, and one lab's roundup of twelve sealers (E·01, E·18, E·09, E·12, E·07, E·13, E·15, E·27). That roundup measured a FoodSaver V4400 and neither of our two machines (E·27). Anova links its quick start guide as a Google Drive file that now asks for a sign-in, and Anova's support site closed the connection when we tried it on October 23, so for its liquid warning we lean on our capture from August (E·04). Our review of the FoodSaver V4440 covers that machine at more length, including the one score we could give it (64/100, low confidence).

Availability, checked October 23, 2026: Anova's store page showed an Add to cart button (E·02) and FoodSaver's V4440 page showed Add to Cart (E·19). An undated FoodSaver support answer saying the V4440 is out of stock is contradicted by the live page (E·19).

The short table

Values are the makers' statements and the independent sources named in each cell. No column carries a winner flag, because the rows split. The independent-measurement row and the removable-gasket row favor the Anova. The warranty-length row favors the FoodSaver, and so does the second-tool row, which is our judgment, since the Anova has an accessory port and hose but no handheld. The drip-tray row splits: the removable tray is the FoodSaver's and the removable gasket is the Anova's. Both machines have built-in roll storage and a cutter, so that row favors neither. Strength, speed and noise cannot be ranked, because only the Anova has numbers. Prices are left out on purpose: both makers' prices moved or carry sale pricing (E·02, E·19).

Whose numbers these are

The Anova's numbers belong to the Anova. Shouldit tested a new unit and recorded 68 kPa, a 36 second cycle on its review page, 83.0 dBA and a weight of 5.0 lb (E·09). Its separate comparison page against another FoodSaver lists a 67 kPa dry test in 14 seconds, and we cannot reconcile the two cycle times (E·12). It sealed one beef bag in moist mode on the first attempt and the seal held through the bath, with no bath temperature or duration on the page (E·10). America's Test Kitchen reports the Pro kept dry and wet foods sealed over time (E·07). That is real, and it is still one unit on one bench and one bag in one bath.

The FoodSaver's numbers are the maker's, and some belong to a different model. FoodSaver files the V4440's manual under V4400 Series, and no FoodSaver page we read says the two are identical hardware (E·18). TechGearLab measured a V4400 at 16.0 inHg and reports it sealing more than 30 bags in a row, but that is a different model number measured in different units by a different lab, so we do not set it beside Shouldit's kPa (E·27). Everything we say below about the V4440's behavior is the manual's statement or an owner's report.

Liquids and moist mode

Anova's product page promises a machine that handles the juiciest of foods (E·03). Its quick start guide carries a crossed-out-bag icon and the words avoid using liquids in the bag (E·04). Owners who bag liquids on the Pro describe freezing sauces and soup first, or pressing Seal again after a Pulse cycle when the sealing surface may be wet, and a small catch area that has to be cleaned after every significant wet use (E·15). Shouldit's moist test peaked at about 45 kPa where its dry test reached the high 60s, which fits The Gadgeteer's description of moist mode as reduced suction (E·12, E·13). America's Test Kitchen said the wet mode let testers seal foods with liquid especially well, which we read as food in its liquid, not a bag of broth (E·07).

FoodSaver's manual is blunter. It lists too much liquid in the bag as a cause of a failed seal and says to freeze first, and it tells owners to pre-freeze meat and fish for an hour or two (E·22). A FoodSaver support answer says soups can be sealed after pre-freezing, and one long-term owner writes that the V4440 never sealed anything with liquid unless it was frozen, even with Moist selected (E·23). Moist on the V4440 is a setting name. The manual says it is for moist or juicy food, and nobody has measured what it does to the cycle (E·21).

So the two read alike on free liquid, and they differ in record. The Anova has a measured moist-mode seal that survived a bath once and America's Test Kitchen's endorsement for wet foods. The V4440 has a setting and a warning. Either way, the freezer step does the work.

Starting a cycle, and stopping it early

On the V4440 you insert the bag and the machine senses it, grasps it, vacuums and seals. FoodSaver's manual tells you to use two hands, slowly, with the open end curled down, and to keep holding until the pump starts (E·20, E·24). A reviewer on FoodSaver's own page, who has owned the model for several years, says lining the bag up to trigger the vacuum is far more difficult than it should be and that they reinsert it several times (E·25). That is one report, not a rate. The page's star average is 4.2 from 176 reviews, and Anova's own page shows about 4.1 from 646, so the stars do not separate the machines and neither average is a failure count (E·17, E·19).

The Anova has no sensor in the sources we read. You close the lid with one hand, press Vacuum & Seal and watch (E·38). If you want the vacuum to stop early, Pulse vacuums only while you hold it, which Shouldit names as the workaround for the 40 percent breakage it saw on a crunchy-food load in automatic mode, and which it says takes monitoring and some trial and error (E·11).

The V4440 has its own early exit. Its Seal button is an Instant Seal that stops the vacuum and seals, and the manual says this prevents crushing delicate items such as bread and pastries (E·24). That is a stop-and-seal, not a hold-and-release. CulinaryReviewer lists a pulse mode for delicate items on the V4440, which the manual does not show, so we cannot say the V4440 has no manual stop at all (E·35). No source measured the V4440 on fragile food, so we cannot say which protects a chip better.

Duty cycle and cool-down

FoodSaver's manual sets a rule: wait 20 seconds between seals. Under heavy use the unit can shut itself off with the red light flashing, and the troubleshooting table says to wait 20 minutes for it to cool (E·26). Against that, TechGearLab's V4400 sealed more than 30 bags in a row without needing to cool, and nobody has reconciled the two, partly because the models differ in number (E·26, E·27).

Anova says the Pro was built to handle over 100 continuous seals, and we found no Anova rest rule and no test of the claim (E·01). The nearest thing to a field report is a 2023 owner thread: after 18 bags in a row the pump often did not draw a vacuum until he waited or rearranged the bag, and nobody replying diagnosed it (E·16). One thread does not undo a maker's rating, and a maker's rating does not undo one thread.

The tools around the seal

The V4440 carries more built in. A retractable handheld sealer handles zipper bags, jar sealers, bottle stoppers and containers through an Accessory button, and FoodSaver's own quick start limits its zipper bags to pantry and fridge use (E·20, E·29). A Marinate button runs a twelve minute sequence of vacuum pulses and rests (E·29). The roll storage and cutter are built in, and the extra-wide sealing strip is described as two times wider, with no baseline and no measured width (E·28, E·30). The removable drip tray holds liquid sensors and goes in the dishwasher's top rack, though the lower gasket is listed as non-removable (E·21, E·28). One owner reported the handheld's nipple broke off on bottle stoppers (E·37).

The Anova's tools are fewer and more conventional: a double seal, bag storage and cutter, and an accessory port with an included hose for containers, jar lids and wine bottles, but no handheld (E·01). Shouldit says it has no removable tray, though owners describe a small catch area for overflow (E·12, E·15). Its gasket lifts out and washes (E·14). America's Test Kitchen found its zip-style cutter flimsy and prone to jamming. Shouldit measured the Pro at 83.0 dBA, and we found no noise figure for the V4440 (E·07, E·09, E·27). Neither maker publishes a seal width in measurements, and we found no independent seal-width measurement for either (E·01, E·28).

Bags, bath heat and warranty

America's Test Kitchen lists the Pro as compatible with generic bags (E·08). Anova sells its own rolls and calls its bags the only ones designed for sous vide, a claim the roll listing does not back with a temperature (E·05, E·06). FoodSaver's manual advises FoodSaver bags for best results and names FoodSaver brand bags as a fix for a melting bag, and one comment reprinted by a comparison site says other makers' rolls worked well (E·31, E·34). Bag waste is a separate matter on the FoodSaver side. The manual asks for at least 3 inches of empty bag above the food, and CulinaryReviewer, which calls the V4440 an older design in FoodSaver's 4000 line, names the extra bag the automatic sealer needs as its biggest complaint without giving a figure (E·31, E·35). Whether the V4440's sensor treats a third-party bag the same way has not been measured by anyone we found, so our guide to generic bags with FoodSaver machines applies with that gap (E·34). We found no per-foot comparison of the two makers' rolls that uses the same size, so we do not rank bag cost.

On heat, the only FoodSaver figure in the manual is for reheating: a low simmer below 170°F (E·36). Shouldit's bath test gave no temperature (E·10). Both are makers' or testers' statements, and neither is a cooking-bath rating.

On warranty, FoodSaver gives five years, tied to purchase from FoodSaver or an authorized seller, and its chart lists handheld appliances at one year without saying how the V4440's built-in handheld is treated (E·32, E·33). The manual's exclusions do not mention bag brand, though it excludes use contrary to its instructions, and those instructions advise FoodSaver bags (E·31, E·32). Anova's store page gives two years (E·02). Neither machine lists an app or subscription, so there is no dependency to weigh (E·01, E·19).

What would change this

An independent suction reading, timed cycle or bath result on a unit labeled V4440 would let us compare strength and speed, which today we cannot (E·27). A statement from FoodSaver that the V4400 and V4440 are the same hardware would let the TechGearLab V4400 result count for the V4440 (E·18, E·27). A second instrumented Anova test with a stated bath temperature would turn one bag into a record (E·10). A test of either machine on a delicate load, with the V4440's Instant Seal and the Anova's Pulse side by side, would settle which protects soft food (E·11, E·24).

The comparison also depends on documents we could not fully read. Anova's quick start guide could not be re-opened on October 23, so its liquid warning rests on an August capture (E·04). The weight of the V4440 is given as roughly 7 pounds in one FoodSaver answer and we found nothing that settles it (E·19).

If free liquid is the job, our guide to chamber versus external sealers covers the machine type built for it. If one of these two was a FoodSaver you could no longer find new, our Anova Sealer Pro versus FoodSaver V4840 comparison covers the V4840 and names the V4440 as the nearest current model. The Anova Pro review scores that machine on its own evidence (75/100, medium confidence), and the two review scores rest on different amounts of evidence, so we do not set them against each other.
