You’ve probably seen those cheap, loud suction sealers at Costco. They’re fine. They work for a while, until you try to seal a bag of chicken thighs with a little too much marinade and—bam—the machine sucks up the liquid, ruins the seal, and leaves you scrubbing goop out of a plastic tray. It’s annoying. The Anova Precision Chamber Vacuum Sealer is the solution to that specific, messy headache, but honestly, it’s a lot more than just a liquid-friendly bag closer.
It’s heavy. When you pull this thing out of the box, you realize it’s not a toy. Most home cooks are used to "edge" sealers, but a chamber vac works on a totally different physical principle. Instead of sucking air out of the bag, it evacuates air from the entire pressurized chamber. The pressure stays equalized inside and outside the bag, meaning liquids don't get sucked out. You can literally seal a bag of pure water. It’s wild to watch.
The Physics of Why Chamber Vacuum Sealers Actually Matter
Most people think vacuum sealing is just about stopping freezer burn. That’s the boring part. The real magic of the Anova Precision Chamber Vacuum Sealer happens because of how it handles atmospheric pressure. When the air leaves the chamber, the air trapped inside the food—like the tiny pockets of oxygen in a slice of watermelon or a cucumber—expands and escapes. When the pressure is released at the end of the cycle, the marinade or liquid in the bag is forced into those vacated spaces.
This is called compression.
Chefs have been doing this for years to change textures. If you put a piece of watermelon in here with a little lime juice and hit the "infuse" button, it comes out looking like raw tuna and tasting like a concentrated flavor bomb. It’s not just "marinated." The structure of the fruit is physically altered. Anova made this accessible for a few hundred bucks, whereas these machines used to cost two grand and weigh as much as a small engine.
Let's Talk About the Size Problem
I’m not going to lie to you: this thing is a beast. It’s about the size of a large microwave's footprint, though it's shorter. If you have a tiny apartment kitchen with zero counter space, you’re going to hate storing it. But if you’re the type of person who buys half a cow or spends Sundays meal prepping twenty portions of carnitas, the footprint is a fair trade-off.

The chamber itself is surprisingly roomy, but you aren't going to fit a whole turkey in there. It’s designed for standard bags, roughly 11 inches by 10 inches. If you’re trying to seal a massive rack of ribs, you’ll still need to use the "accessory" port or just cut the ribs down. That’s the one limitation of chamber sealers—you are physically limited by the size of the box.
Why This Specific Anova Model Changed the Game
For a long time, the chamber vac market was split. You had the VacMaster VP215, which is a legendary workhorse but uses an oil pump. Oil pumps are quiet and powerful, but they require maintenance. You have to change the oil. It’s a whole thing. Then you had the entry-level dry pump machines that were often flimsy.
Anova took the middle ground. They used a dry pump, so there’s zero maintenance. No oil changes. No mess.
Is it louder than an oil pump? Yeah, a bit. But compared to a standard FoodSaver? It’s actually more of a low, rhythmic hum rather than that high-pitched screeching sound that makes your dog run for cover. It feels professional. The lid is thick glass, so you can watch the bags "puff up" during the cycle, which is weirdly satisfying and also helps you make sure your liquids aren't boiling over.
Yes, liquids boil in a vacuum. It’s a cool science trick. Because the pressure drops, the boiling point of water drops too. If you see your soup starting to bubble, you can hit the "seal" button early to stop the cycle before it makes a mess.
Small Details That Most Reviews Miss
- The Bags are Cheaper: This is the secret nobody tells you. Edge sealers require those expensive, textured "mesh" bags. Chamber sealers use plain, smooth pouches. We’re talking pennies per bag versus nearly a dollar for the fancy ones. If you seal a lot, the machine literally pays for itself in two years just on plastic savings.
- Cooling Down: If you’re doing 50 bags in a row, the heating bar needs a second to breathe. The Anova handles heat well, but I’ve noticed the seal gets a bit "melty" if you don't give it ten seconds between hits.
- The Infusion Cycle: There’s a dedicated button for this. It pulses the vacuum. It pulls air out, lets it back in, pulls it out again. This is what you use for making quick pickles or booze-infused fruit. It’s not just a gimmick; it works in about three minutes compared to two days in the fridge.
Can It Actually Help With Your Grocery Bill?
Honestly, the Anova Precision Chamber Vacuum Sealer is a hedge against inflation. I know that sounds like a stretch, but hear me out. Buying meat in bulk—the "family packs" or the whole sub-primals from a butcher—is significantly cheaper.
The problem is usually that by the time you get to the third pound of ground beef, it’s got those gray ice crystals on it. That’s oxygen at work. By removing almost 100% of the air (which edge sealers can't do), you’re looking at a shelf life that’s 5x longer. I’ve pulled steaks out of the freezer that were sealed in a chamber vac eighteen months ago, and they tasted like they were bought yesterday.
Using It for More Than Just Sous Vide
While Anova is a sous vide company, this machine is a standalone powerhouse. You should be using it for things that have nothing to do with water baths.
- Resealing Jars: You can put small mason jars inside the chamber. Put the lid on loosely, run a cycle, and the vacuum will pull the lid shut. It’s great for keeping nuts or dried herbs fresh.
- Saving Wine: Use the accessory hose to pull air out of opened bottles.
- Compression: As mentioned, compressing fruits and vegetables. Try it with cucumbers and rice vinegar. It’s a total texture shift.
- No-Leak Marinating: Since you can seal liquids, you can put a piece of fish and a cup of soy-ginger marinade in a bag and seal it perfectly. No air means the marinade is in direct contact with every millimeter of the protein.
Comparing the Anova to the Competition
If you're looking at the Anova Precision Chamber Vacuum Sealer, you've probably also looked at the Avid Armor USV20 or USV32. They are very similar. The Avid Armor units are also dry-pump and highly rated.
However, the Anova usually wins on the user interface. It’s cleaner. It looks like a modern kitchen appliance rather than a piece of medical equipment. The touch controls are intuitive, and it doesn't have a bunch of confusing gauges that look like they belong in a submarine.
The real competitor is actually Anova’s own "Pro" version of the suction sealer. Don't get confused. The "Pro" suction sealer is still an edge sealer. It still struggles with liquids. If you can afford the jump in price and have the space, the chamber version is a completely different class of tool.
Things That Might Annoy You
Nothing is perfect. The Anova is heavy—like 25 pounds heavy. You aren't going to want to move it once it’s set down. Also, the lid gasket needs to be kept clean. If a tiny piece of salt or a drop of sauce gets on that rubber seal, the machine won't be able to create a vacuum. You’ll sit there wondering why it’s running for two minutes without doing anything. Just wipe the gasket. Problem solved.
Also, it’s worth noting that this machine is designed for "home" use. If you’re a hunter processing three deer in a single weekend, you might want to look at a heavy-duty oil pump machine. The Anova is built for the enthusiast, not the commercial meat processor. For the average person cooking dinner or prepping for the week, it’s more than enough.

Final Thoughts on the Anova Precision Chamber Vacuum Sealer
If you're serious about food, or even just serious about not wasting money on freezer-burned chicken, this is one of those "buy it once" tools. It changes how you shop, how you prep, and honestly, how your food tastes. The ability to handle liquids is the "killer feature," but the cost savings on bags is the long-term win.
Stop buying the cheap suction machines that break every two years. Get something that uses physics to its advantage.
What to Do Next
- Clear a spot: Find a permanent 15" x 18" spot on your counter or a heavy-duty pull-out shelf.
- Buy the bags in bulk: Don't buy the Anova branded bags if you want to save money; search for 8x10 or 10x13 chamber vacuum pouches on restaurant supply sites.
- Test with fruit: The first thing you should do is compress some pineapple with a little chili lime seasoning. It will change your life.
- Check your seals: Always double-check that the bag is laying flat across the seal bar. If it wrinkles, the air might sneak back in.
The Anova Precision Chamber Vacuum Sealer represents a shift in home cooking technology that finally brings a high-end restaurant technique into a manageable, maintenance-free package for the rest of us. It’s an investment, but for anyone who takes meal prep or sous vide seriously, it’s the only way to go.
