My salad stayed fresh
“Very easy to use. My salad was still fresh five days after I made it. I also used it with regular Mason lids.”
MasonVac
Freshness made simple.
Seal your Mason jars in 30 to 60 seconds, then open, serve and reseal.
Discover MasonVac
Real vacuum sealing. In your Mason jars.
MasonVac removes air from the jar instead of simply closing a container. Less air exposure for the foods you use every day.
One button, 30 to 60 seconds
Place the device over a compatible lid, then start the sealing cycle.
Jars you can reuse
Open to serve, then reseal what’s left.
Safe storage still matters
Vacuum sealing does not replace refrigeration, freezing or safe canning practices.

My avocado didn't even brown
« I looked at the product for several days, a bit hesitant to try it. Then I did my first test with an already-cut avocado, and it wasn't even brown the next day! For me, that's a real success. Now I'm trying different foods. The tutorial gave me the little push I needed to try it instead of just looking at it. The explanations were very thorough! »
