Avid Armor USV20 chamber review

Avid Armor USV20 Chamber Vacuum Sealer, 11.5 in Seal Bar

By Tom Calder

Our verdict · Researched
3.5 / 5

A chamber sealer evacuates the whole chamber, so soups, stews and marinades stay in the bag instead of being pulled into the machine. It's the step up for people who seal a lot. As with any vacuum packing, Utah State says it isn't a preservation method by itself.

Best for
Soups, marinades and high volume
Skip it if
You mostly seal dry or solid foods
