A chamber sealer puts the whole bag in a sealed box, so liquids stay in the bag and smooth pouches cost less per bag. These are the three home chamber sealers we'd buy.

The Anova is the most compact of the three at about 13.6 × 11.2 × 8.9 in, with a 70 L/min dry pump that needs no maintenance and programs for infusing, quick-pickling and dry foods. It's the only one here with a two-year warranty. It has no accessory port, so it can't vacuum jars or canisters.

Questions
Do chamber sealers need oil changes?
All three here use dry or oil-free pumps, so no. Commercial models with rotary oil pumps do.
Can a chamber sealer use regular FoodSaver bags?
Usually, yes, but smooth chamber pouches are cheaper.
