Vacuum Sealers

Published August 2014

How we tested

Vacuum sealers are great for storing food. We use them at the test kitchen to help store hundreds of pounds of food weekly. They’re popular at home, too, among hunters and fishermen freezing their hauls, as well as among bulk shoppers, gardeners, and farmers’ market frequenters. They work by pulling air away and creating a tight seal around the food, blocking it from elements that hasten deterioration. We wrote about vacuum sealers a few years ago, but of the eight models we tested, only the winner, the Weston Pro 2300, still exists. Ours is still chugging along, sealing hundreds of pounds of meat weekly, but at $500, its cost and size make it impractical for most home cooks.

Fortunately, a new wave of sealers offers less expensive options, so we set ourselves a price cap of $200 and bought seven models to test, ranging from about $50 to $199. We sealed and froze strawberries, ground coffee, steaks, chicken, and individual portions of lasagna and monitored them for signs of freezer burn. We also portioned and sealed pretzels and cereal and stored them in the pantry, sampling them periodically to gauge freshness.

Comparing Vacuum Strength and Sealing Styles

We have good news to report: In our previous testing, only our winning model kept food freezer-burn-free for two months. This time at two months, food from six of the seven sealers still looked good. But eventually, a pattern emerged. Sealers come in two basic styles—heat seal or valve seal—and the latter lost their seals faster. Valve sealers use what look like extra-sturdy plastic storage bags; you zip the food in and the sealer then sucks the air out through a valve on the bag. We were intrigued by valve versions; they’re typically smaller, quieter, and cheaper. But they aren’t as foolproof because their bags are made of thick, often brittle plastic. It’s difficult to be certain they’re closed, and once they are, a firm jostle can break the seal. One valve sealer proved successful; at two and a half months a few packets had loosened seals but most still looked great, thanks to a small plastic clamp that you run over the zipper to definitively close the bag before sealing. Heat sealers, on the other hand, work by pulling away the surrounding air and closing off the plastic by melting it shut. With these sealers, it was easy to be sure the bags were closed—was the plastic melted or not?

The second factor was power. Vacuum strength is measured in inches of mercury (inHg); a higher number means a stronger suction. There’s a reason the Pro 2300 weighs a whopping 26 pounds: It houses a large motor that pulls 28 inHg of vacuum power. Not every manufacturer shared its sealer’s strength, but with those in our testing that did, we found a range from 11 to 23 inHg and the machine with the strongest vacuum kept food the freshest because less air was left in its bags. Stronger vacuums went hand in hand with larger motors, and for heat sealers a larger motor can support a more powerful seal bar—the chamber that heats up and seals off the plastic. A powerful seal bar heats up faster to quickly seal at maximum suction and seals more consistently, as it can power through small wrinkles and specks of errant food or liquid.

Also important: a manual pulse. Automatic pulse mode is too strong and crushed delicate items in its quest to vacate the air. Manual mode allows control over the vacuum, so you can stop it before it crunches your food. Our winning sealer had a responsive pulse mode, a large motor, and a powerful vacuum. It kept frozen food looking fresh and pantry items crisp for three months and counting.

Crowning the Best Vacuum Sealer

Our new winner is the home version of our favorite Pro 2300. The Pro 2300 has the muscle to seal hundreds of pounds of meat daily, and if money and space aren’t an issue, it’s still the best sealer we’ve tested, but for home use, our new winner has the muscle, seal quality, durability, and smaller footprint we require. The one valve sealer we liked kept the majority of its food fresh for at least three months, and at nearly $70, it’s a great choice for the occasional home sealer; we’re naming it our Best Buy.

Design Trifecta 360 Knife Block

Admittedly expensive, this handsome block certainly seemed to live up to its billing as “the last knife block you ever have to buy.” The heaviest model in our testing, this block was ultrastable, and its durable bamboo exterior was a breeze to clean. Well-placed medium-strength magnets made it easy to attach all our knives, and a rotating base gave us quick access to them. One tiny quibble: The blade of our 12-inch slicing knife stuck out a little.

Schmidt Brothers Downtown Block

This roomy block completely sheathed our entire winning knife set using just one of its two sides—and quite securely, thanks to long, medium-strength magnet bars. Heavy, with a grippy base, this block was very stable. An acrylic guard made this model extra-safe but also made it a little trickier to insert knives and to clean; the wood block itself showed some minor cosmetic scratching during use.

$141.90*

Schmidt Brothers Midtown Block

This smaller version of the Downtown Block secured all our knives nicely, though the blade of the slicing knife stuck out a bit. With a base lined with grippy material, this block was very stable. An acrylic guard afforded extra protection against contact with blades but made it a little harder to insert knives and to clean; the wood itself got a little scratched during use.

Swissmar Bamboo Magnetic Knife Block

This small, scratch-resistant model had a stable, rubber-lined base and could hold all our knives, though the blade of the 12-inch slicing knife stuck out a bit. But inch-long gaps between its small magnets made coverage uneven and forced us to find the magnetic hot spots in order to secure the knives. Its acrylic guard made it safer to use but harder to insert knives and to clean.

Messermeister Walnut Magnet Block

This handsome block was done in by its shape—a tippy, top-heavy quarter-circle that wasn’t tall or broad enough to keep the blades of three knives from poking out. It lacked a nonslip base, and its extra-strong magnets made it unnerving to attach or remove our heavy cleaver. Finally, it got a bit scratched after extensive use.

$129.95*

Epicurean Standing Knife Rack 12"

This magnetic block sheathed all our knives completely, though with a bit of crowding. But it was hard to insert each knife without hitting the block’s decorative slats on way down, and because the block was light and narrow, it wobbled when bumped. Worse, we couldn’t take it apart, so splatters that hit the interior were there to stay. Additionally, the outside stained easily, and when we wiped it down, the unit smelled like wet dog.

Kapoosh Rondelle Knife Block

This model stabilized knives with a mass of stiff, spaghetti-like bristles that shed and nicked easily after extensive use, covering our knives with plastic debris. While all our knives fit securely, several of the blades stuck out, making this unit feel less safe overall. Finally, though the bristles could be removed and cleaned in the dishwasher, their nooks and crannies made this block hard to wash by hand.

Kuhn Rikon Vision Knife Block, Clear

This plastic block required us to aim each knife into the folds of an accordion-pleated insert that was removable for easy cleaning but got nicked easily with repeated use. Because we could only insert the knives vertically, longer knife blades stuck out; a cleaver was too wide to fit. The lightest model in our lineup, this block was dangerously top-heavy when loaded with knives.
