How We Research

Updated on

Every guide on FreezerBagPicks starts with one question: will this sealer suit your kitchen, your freezer and the food you seal?

Here is how we answer it.

1. We start with the machine type

An external sealer sits on the counter and pulls air from the open end of a bag. A chamber sealer closes the whole bag inside a lid, which suits liquids and big batches.

We check which type each product is and what it needs, like counter space, bag style or a roll cutter. When bag fit matters, we go by what the maker says works.

2. We compare specs and features

We look at seal bar length, pump strength, dry and moist modes, chamber size, built-in cutters and any jar attachment. We also note the warranty terms the maker lists.

When a detail comes from the maker, we say so.

3. We look at buyer feedback

We read through what buyers report after using a sealer. We look for patterns, like weak seals on moist food, loud pumps or bags that are hard to find.

One angry review doesn't sink a product. A pattern does.

4. We score each product

Our score weighs specs, features and buyer feedback against what you're shopping for. A sealer that's great for big batches of meat may score lower in a guide for a small kitchen.

Scores spread out on purpose. A 10 is rare.

5. We keep pages up to date

Products change, and some disappear from stores. When we update a guide, the "Updated on" date at the top changes with it.

What our picks are not

Our picks are research, not lab tests. We don't claim to have used every sealer we cover.

Our guides don't replace the maker's manual. For sealing, storage and sous vide, follow the maker's steps and the guidance from the USDA or the National Center for Home Food Preservation.

Sealing doesn't make food safe on its own, and we don't promise how long sealed food will keep.
