Why a chamber sealer
It seals what a suction sealer can't.
A suction sealer pulls the air out through the open end of the bag, and liquid can follow it. A chamber sealer holds the whole bag inside the machine and takes the air out of the chamber, so the liquid stays in the bag and the seal holds.
Suction sealerAir leaves through the bag opening
Chamber sealer, like the USV1The whole bag sits in the chamber
Liquids stay put
Soups, sauces, brines, marinades and infusions seal airtight because the liquid is never pulled toward a suction port.
Delicate food stays whole
Berries, fish and fresh pasta come out whole instead of crushed.
The least expensive way in
The USV1 is the least expensive way into chamber sealing in our line, at $219.
The whole pouch sits inside the chamber.
Soups, sauces and marinades are the jobs a chamber sealer is made for.
If you seal a few dry items a month, a suction sealer may be all you need. The USV1 is for people who seal wet food, delicate food, or portion a lot of meals.
Right-sized
Sized for how one or two people cook.
The USV1 is built for apartments, RVs, boats and kitchens where counter space is the constraint. It is small enough to live in a cupboard between sessions, and light enough to lift with one hand.

Bigger jobs, like bone-in cuts or bulk harvests, are what the USVX and the USV20 are built for. Pouches on the USV1 stop at 10 x 10 in. We cover the difference below.
Easy to start
An easy first chamber sealer.
The most common mistake on any chamber machine is a misaligned, half-sealed pouch. A pouch ledge and an integrated clamp are there to stop it.
Set the pouch on the ledge
The ledge puts the bag at the right height and the clamp holds it there while you close the lid.
Pick a level and a seal setting
Three vacuum levels and three seal time settings. Nothing to time.
Press Auto Vac and Seal
One touch runs the cycle. Progress lights show where it is.
Inside the USV1: pouch ledge, pouch clamp, 10 in seal bar, accessory port.

★★★★★
“I love this Vacuum Sealer so far! It does a wonderful job. My only frustration has been the availability of the 8X10 bags, which is the perfect size for this model.”
“I love it. It does a great job and is simple to use. Maybe a little too nice... as I now seem to buy more at the grocery store just so I have an excuse to use it.”
David K., verified buyer of the USV1. April 2026.

Keep your suction sealer for oversized cuts. The USV1 does not replace every sealer you own. Pouches stop at 10 x 10 in.
Who should skip it. If you seal a few dry items a month, or mostly very large cuts, or have no shelf or cupboard space for a machine, a chamber sealer is the wrong tool.
The USV1 is the smallest chamber sealer we make. It is meant for apartments, RVs, boats and any kitchen where counter space is the limit, and it is the least expensive way into chamber sealing in our line. If you cook for one or two and portion meals for the week, it is sized for that.
How big is it, and where does it live?
12 x 12 x 6.25 in and 13 lb. You can lift it with one hand, and it is small enough to live in a cupboard between sessions. The chamber inside measures 10.5 x 10 x 2.25 in, so food goes in flat in a pouch.
Can it seal soup, sauce and other liquids?
Yes. Soups, sauces, brines, marinades and infusions seal airtight because the liquid is never pulled toward a suction port. Delicate foods such as berries, fish and fresh pasta come out whole instead of crushed.
Does it replace my suction sealer?
Not entirely. The largest pouch it takes is 10 x 10 in. Keep your suction sealer for oversized cuts. If you seal bone-in cuts or bulk harvests often, the USVX and the USV20 are built for that.
I have never used a chamber sealer. Is this hard?
No. A pouch ledge and an integrated clamp position the bag and hold it while you close the lid. There are three vacuum levels, three seal time settings, one-touch Auto Vac and Seal, and progress lights through the cycle.
Which pouches does it use?
Chamber pouches, up to 10 x 10 in. These are smooth pouches, not the textured bags a suction sealer needs. The USVX and USV1 variety pack has 300 pouches: 100 each of 10 x 10, 8 x 10 and 6 x 8 in.
What comes in the box?
The USV1 chamber vacuum sealer, a starter pack of chamber pouches, an accessory hose for jars and canisters, and a quick-start guide and manual.
What are the return and warranty terms?
Vacuum sealers can be returned within 30 days of the order date for a full refund, less return shipping label fees. A 15 percent restocking fee applies unless the unit comes back clean, like new, in its original packaging with all accessories. The USV1 has a 1 year warranty.
