How is a chamber sealer different from a regular vacuum sealer?

A chamber machine pulls a vacuum around the entire bag inside a sealed chamber, so liquids do not get sucked toward the seal. Suction sealers pull air through the bag opening, which draws liquids up and can spoil the seal.

Can it seal soups and other liquids?

Yes. Chamber vacuum sealing is the main reason to choose it: soups, stews, sauces and marinades seal without leaking. Leave headroom above the liquid and keep the bag below the chamber's maximum fill line.

What do the three preset buttons do?

Each preset stores a vacuum level, a vacuum hold time and a seal time, so you can repeat the same result for a given food. Set them once for, say, raw meat, liquids and dry goods, then seal with one press.

Does it come with bags?

Yes. The box includes six one-pint, six one-quart and six one-gallon vacuum bags. Chamber sealers use smooth, channel-free bags, which are usually cheaper in bulk than textured suction-sealer bags.

How much room does it need?

It measures about 18.2 by 14 by 11.8 inches and weighs roughly 55 lbs, so plan a permanent spot on a sturdy counter. It is not a machine you will want to lift in and out of a cupboard.

Is it worth it over a cheaper suction sealer?

If you mainly seal dry foods and solid portions, a suction sealer does the job for far less. If you seal liquids, wet marinades or do vacuum-pickling regularly, the chamber design and presets are the reason to step up.
