FreshVault Pro – Cordless Jar Vacuum Sealer
How it works
No pumps, no plastic bags, no special equipment. If you own a jar, you own a vacuum container.
Fill any jar
Leftovers, berries, meal prep, coffee, dry goods — use the jars already in your cupboard (Ø 1–3.5").
Place & press
Set the sealer on the lid and press the button. The auto-stop motor pulls a -60 kPa vacuum in ~30 seconds.
Stay fresh 5× longer
Oxygen out, freshness in. Berries last weeks, not days — and your food budget stops going in the trash.

FAQ & food safety
Does it work with my existing jars?
Yes. The universal adapter system fits jar openings from 1" to 3.5" in diameter — mason jars, jam jars, pickle jars and most twist-off glass jars.
How much longer does food really last?
Removing oxygen slows oxidation and aerobic spoilage. Most fresh foods stay good up to 5× longer when refrigerated. Results vary by food type and storage temperature.
Is vacuum sealing a replacement for refrigeration or canning?
No. Vacuum sealing delays spoilage but does not kill bacteria or sterilize. Always refrigerate or freeze sealed perishables and consume them promptly.
