Avid Armor USV20 chamber review
Avid Armor USV20 Chamber Vacuum Sealer, 11.5 in Seal Bar
By Tom Calder
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
