Tested the “Best” Mason Jar Vacuum Sealers: Proof vs Hype (Watch 1st)

Описание: John from http://www.DiscountJuicers.com puts two of the most heavily advertised mason jar vacuum sealers to the test — Plateful VacuFresh and Mason Genie — to find out if their big marketing claims match real-world performance. In this episode, John goes beyond opinions and uses an in-jar differential pressure gauge to measure actual air removal, so you can see what these popular pumps are really doing before you spend your hard-earned money.

Plateful promotes “complete air removal technology” and suggests near-total air removal, while Mason Genie claims it “sucks all the air out” for a perfect airtight seal. John breaks down what those claims actually mean, why percent oxygen left in the jar matters, and how even small differences in remaining oxygen can affect oxidation, nutrient loss, and spoilage over time.

To keep the testing fair and repeatable, John uses the same jar, the same test method, and a high-quality reusable vacuum lid while comparing Plateful and Mason Genie alongside other well-known options like SealVax and FoodSaver. He then explains why vacuum strength matters most for real use cases like storing fresh juice, cut produce, batch-prepped meals, and long-term pantry items.

In this episode, you’ll learn:
How to test mason jar vacuum sealers with a pressure gauge
What vacuum numbers actually mean for oxygen remaining in the jar
Why oxygen drives browning, oxidation, and faster food spoilage
Why most standard mason jar lids fail and leak with repeated use
Which lid features make vacuum sealing easier and more reliable
How stronger vacuum can improve storage for juice, dry goods, nuts, and seeds
