Airtight Food Storage Containers
Shop by type
Press the lid, hear the air leave with a soft shush, and the flour, coffee and spices inside stay fresh weeks longer instead of going stale days after you open the bag.
Airtight Food Storage Containers
Flour goes stale, rice takes on whatever the cupboard smells of, and the cereal box you rolled shut was never really airtight. A TightVac fixes that in one move. Press the lid and it sinks with a soft shush, pushing the air already inside back out, so there is far less oxygen left to work on your food. That is why sealed dry goods stay fresh up to three times longer than the bag or box they came in.
The one thing that decides which to buy
It comes down to what you are storing and how fast you get through it. Dense dry goods like flour and rice hit a container's weight limit quickly. Airy things like coffee and cereal fill the space first. Size to the contents, not the label, and the rest looks after itself, because every container in the range shares the same 2-way valve and the same BPA-free body. All the freshness of the pricey metal canisters, at a fraction of the price, which is part of why over ten million have sold.

|---|---|---|---|
| Everyday staples: pasta, rice and cereal | 1.3–2.35 L, wide mouth | Weekly kitchen restocking | TightVac 1.3L · TightVac 2.35L |
| A 1 kg bag of flour or sugar | 3.8 L, scoop-friendly | Home bakers keeping a bag dry | KiloVac 3.8L |

Short version: not sure? The 1.3 L and 2.35 L cover most kitchens. Buying in bulk, go 3.8 L or 10 L. Storing spices and supplements, the 0.29 L and 0.57 L.
What we carry
- TightVac. The core line, 0.29 L to 3.8 L, and where most people start: flour, rice, pasta and coffee. The TightVac 1.3L and 2.35L are the everyday sizes.
- MiniVac. The 0.12 L pocket size, for small herb portions, a few days of supplements, or anything you carry rather than store.
- VitaVac. A 0.06 L jar shaped for vitamins, supplements and capsules. The seal keeps out the humidity that degrades them.
- KiloVac. The bulk end, up to 3.8 L: a sack of flour or a kilo of coffee with somewhere sensible to put it. See the KiloVac 3.8L.
- BreadVac. 10 L, tall rather than wide, built around a loaf and the right shape for bulk cereal and large pasta. See the BreadVac 10L.
Getting it right
Leave headroom. Dry goods settle, some expand, and the valve needs room to move the air. Keep containers out of direct sun and off the counter beside the hob, because light and heat undo storage faster than most people think. They are for dry storage, not liquids, and not a stand-in for the fridge. Two things worth knowing: hand-wash only, with a full dry before you reseal, because dishwasher heat is what wears a seal out. And do not fill a container to the brim if it is going in the freezer, since the contents expand.
Common questions
What is the best container for storing dry food?
One that is opaque, seals properly, and keeps air off the food rather than just holding the lid on. Light, moisture and oxygen are what spoil dry goods, and an ordinary tub only slows the last one. A solid-body TightVac covers all three: opaque walls, a one-button seal you can feel close, and a 2-way valve that even lets freshly roasted coffee vent without letting oxygen back in.
Are airtight containers really better than the original packaging?
Yes, for anything you open more than once. A folded bag or a clipped box lets air straight back in every time you reach in, and paper packaging quietly draws moisture from the cupboard. A sealed container holds the contents steady between uses, and a TightVac goes further by taking out the air already inside rather than trapping it. That is where the fresh-up-to-3x-longer difference comes from.
What size do I need for a 1 kg bag of flour?
A 1 kg bag of flour settles into the KiloVac 3.8L with room to scoop. If you keep several baking staples side by side or buy flour in bulk, the BreadVac 10L holds around 2.5 kg. The weights are for dense goods. Lighter contents like cereal or ground coffee fill the space before they reach the limit, so size up if what you are storing is airy.
Do these create a true vacuum?
No, and we would rather say so plainly. It is a strong partial vacuum from a one-button airlock, not a motor. Pressing the lid takes out most of the air sitting around your food, which is the part that affects freshness. It is not a laboratory vacuum and we do not claim it is. If you want the seal pulled down further, the CoffeeVac 3-in-1 Pump adds a hand pump. For everyday dry storage the one-button seal is plenty.
Can I put them in the dishwasher?
No, hand-wash only. Warm water, a mild detergent, and a full dry before you reseal. The rubber seal is what keeps the air out, and repeated dishwasher heat is what hardens it and shortens its life, so this is the one care instruction worth following. Treated that way, a TightVac lasts for years and moves from coffee to flour to trail mix without holding onto smells between uses.
