10 Reasons Home Cooks Are Putting Their Mason Jars to Work with a Hand Pump

There's no special container to buy and no plastic bag to cut open. The MVP system is built around the wide-mouth mason jar — the kind already sitting in most cupboards, whatever the brand. Set a PURE stainless lid on top, pump, and that jar becomes vacuum storage for juice, produce or pantry goods. When you're done, wash the jar and use it again. The Ready-Set-Go set comes with 12 lids, so a dozen of your jars can be working at once. Jars are sold separately, which means you only pay for the part that does the work.

It sounds backward, but the hand pump is quicker. Seven to ten upward strokes takes about six seconds per jar. Electric jar sealers take around 40 seconds. When you're sealing a week's worth of juice or portioning a bulk bag of nuts into jars, that difference adds up fast. There's no waiting for a motor to cycle and no light to watch. Pump, lift off, next jar. Once you've done it a couple of times, it becomes a rhythm.

PURE started as a cold-press juicer company, and the MVP grew out of the question juicers ask most: how do I store it? Vacuum sealing fresh juice and smoothies in mason jars helps them keep up to a week in the fridge — about double the storage life. That makes a single juicing session on the weekend a realistic plan. Fill the jars, pump each one, and stack them in the fridge. Keep juice refrigerated the whole time, and drink the oldest jar first.

Ordinary jar lids aren't built for this much vacuum; they can bend. PURE designed its own: triple-thick 0.4 mm #304 stainless steel with insert-molded silicone gaskets. They're made to be reused, not tossed after one use, and they're dishwasher safe. Wide-mouth only for now, sized to fit standard wide-mouth mason jars. Fill each jar to within about half an inch to an inch and a half of the rim, pump, and the lid holds.

The pump body is aerospace-grade aluminum with a die-cast leaf handle and a stainless steel pushrod; the seals are food-safe silicone. There's no BPA and no PFAS in the system. It's designed to be serviced instead of replaced: the MVP Service Kit has silicone grease and the pump's rebuild o-rings, and replacement lid valves come in packs of six. It's the kind of kitchen tool you buy once.
