It's Ridiculously Easy To Vacuum Seal Your Mason Jars

The solution we've all been waiting for

STEP 1

Fill & Cover

Fill your standard or wide mouth mason jar with food, place a standard mason jar lid on top—no special lids required!

STEP 2

Seal with One Touch

Position SealFresh PRO™ over the lid and press the button. The vacuum pump removes all air in seconds, creating an airtight seal.

STEP 3

Instant Preservation

Your food is now protected from moisture, pests, and spoilage—staying fresh 3-5X longer! Ready to open? Simply use our free jar opener (included) to release the seal.

Why SealFresh PRO™ is the Best Choice (Beware of Knockoffs!)

You may have seen other similar vacuum sealers online, but beware, most are cheap Chinese dupes!

Don't get scammed

Cheap knockoffs from overseas stop working after a few months because they use weak pumps that lose suction.

Others are too complicated

Some models require extra hoses, tubes, or adapters, making vacuum sealing a hassle.

Faulty sealing

Inconsistent sealing means some jars stay airtight while others don’t, leading to wasted food.

Do It For Your Fruits & Veggies

Instantly locks in nutrients

Vitamins and micronutrients dimish over time. SealFresh PRO ensures that your food stays as healthy as the moment you sealed it.

Ideal for preserving fruits and veggies

Fruits & veggies spoil so quickly, especially if they're organic, SealFresh PRO will prolong their life by up to 5X their standard shelf life.

Leafy greens are so expensive

Leafy greens, like kale and spinach, typically start spoiling after 3 days. If they're not eaten in time, there goes your money. Once you start SealFresh-ing them, you'll never go back!
