Airtight Food Storage Containers
Shop by type
Storage that removes the air instead of just trapping it — so flour, coffee and everything in the cupboard taste fresh weeks longer, not just on the day you open the bag.
Airtight Food Storage Containers
Flour goes stale, rice picks up whatever the cupboard smells of, and the cereal box you rolled shut was never airtight in the first place. An airtight food storage container fixes the first half of that by keeping new air out. A TightVac goes further: press the lid and it pushes the air already inside back out, so there is less oxygen left in there to work on your food — which is why sealed goods stay fresh up to 3x longer.
The one thing that decides which to buy
It isn't the model name — it's what you're storing and how quickly you get through it. Dense dry goods like flour and rice hit a container's weight limit fast; airy things like coffee and cereal fill the space first. Size to the contents, not the label, and everything else takes care of itself: every container in the range shares the same 2-way valve and BPA-free body.
| If you need to store… | Look for | Best for | Our pick |
|---|---|---|---|
| Everyday staples — pasta, rice, 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 |
| Bulk buys & meal prep | 10 L, tall body | Big households, batch cooks | BreadVac 10L |
| Spices, supplements, small portions | 0.29–0.57 L, pocketable | Spice drawers, compact stores | TightVac 0.29L · TightVac 0.57L |
| Coffee that's still degassing | 0.8 L + CO₂ valve | Fresh-roast bean drinkers | CoffeeVac 0.8L |
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 — 0.29 L to 3.8 L. The core line and where most people start; flour, rice, pasta, coffee. TightVac 1.3L and 2.35L are the everyday sizes.
- MiniVac — 0.06 L and 0.12 L. Pocket sizes for herb portions, a few days of supplements, anything you carry rather than store.
- VitaVac — 0.06 L. Shaped for vitamins, supplements and capsules; the seal keeps out the humidity that degrades them.
- KiloVac — up to 3.8 L. The bulk end: a sack of flour or a kilo of coffee with somewhere sensible to put it. KiloVac 3.8L.
- BreadVac — 10 L. Tall rather than wide, built around a loaf, and the right shape for bulk cereal and large pasta. BreadVac 10L.
Getting it right
Leave headroom — dry goods settle and some expand, and the valve needs air to move. Keep containers out of direct sun and off the counter beside the hob; light and heat undo storage faster than most people think. These are for dry storage only, not liquids and not a stand-in for the fridge. And they're hand-wash: hot water, dried fully before you reseal, because the seal is the part doing the work and dishwasher heat is what shortens its life.
Common questions
What is the best container for storing dry food?
One that is opaque, seals properly, and keeps air away rather than just holding the lid on. Light, moisture and oxygen are what spoil dry goods, in that order of nuisance, and ordinary tubs only address the last one loosely. A solid-body TightVac covers all three: opaque walls, a one-button seal, and a 2-way valve that even lets freshly roasted coffee vent without drawing oxygen back in. Match the size to what you store and it does the rest.
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 absorbs moisture from the cupboard around it. A sealed container holds the contents at a steady state between uses, and a TightVac takes it further by removing 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. Remember 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're storing is airy.
Do these create a true vacuum?
No. It is a strong partial vacuum created by a one-button airlock, not a motor. Pressing the lid removes most of the air sitting around your food, which is the part that actually affects freshness — but it is not a laboratory vacuum and we do not claim it is. If you want to pull the seal down further, the CoffeeVac 3-in-1 Pump adds a hand pump; for everyday dry storage the standard 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 exactly what hardens and shortens the life of a seal, 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 odours between uses.
