Expert perspective
“Oxygen is what ages food, not time. DAYSEAL box takes it out without turning your berries into jam”
Overview
Overview
Fill it. Press the pump on top for six seconds. Turn the ring on the lid to today.
That is the product. The air the food was sitting in is gone, and in four days you are not standing at the fridge trying to remember.
Air is what ruins food. Everything else on this page is detail.
What is in the set
What is in the set
Seven containers. One cordless pump. Nothing else to buy.
700 ml rectangle, 16.7 x 10.8 x 7.5 cm. Herbs, berries, half an avocado.
1,200 ml square, 16.7 x 16.7 x 7.5 cm. Cut fruit, cheese, cold cuts.
1,500 ml rectangle, 16.7 x 10.8 x 13 cm. Leftovers, cooked grains.
2,000 ml rectangle, 14 x 21.3 x 10.2 cm. Green beans, asparagus, prepped veg.
2,000 ml low rectangle, 16.7 x 27.8 x 7.5 cm. The wide flat one for the shelf under the light.
2,400 ml square, 16.7 x 16.7 x 13 cm. Salad for four, marinating.
4,000 ml rectangle, 27.8 x 16.7 x 13 cm. A whole lettuce, a batch cook, a spatchcocked chicken.
Every lid has its own valve and its own date dial. One pump works on all of them.
Measured by hand, so allow 1 to 2 cm either way.
Using it right
Using it right
Load it dry. Wash produce when you eat it, not when you get home. Water moulds whether the air is there or not.
Leave a finger of headroom. Overfill it and it will not hold a vacuum. This is the number one reason a vacuum container stops working.
Keep it in the fridge. Removing oxygen slows spoilage. It does not replace cold.
What it will not do
What it will not do
Better here than on day four.
No whole ripening fruit. Bananas, pears, peaches, tomatoes, whole avocados. Sealing their own ethylene in with them ripens them faster, not slower. Cut avocado yes. A bowl of bananas no.
No long storage of raw mushrooms or raw garlic. Both are on every food safety list, for the same low oxygen reason.
It is not a canner. It buys you days inside the fridge, not a shelf.
Care, and the seal
Care, and the seal
Boxes and lids on the top rack. Lift the silicone ring out, wash it by hand, let it dry before it goes back.
The silicone is the wear part. On every vacuum container ever made, ours included. Any brand saying otherwise has not owned one for two years.
Ours lift out and are replaceable. A seal that fails inside the first year is on us.

The Word on DAYSEAL
The Container Brand Exposing the 'Airtight' Myth
Six days later, this avocado is still bright green, and we're officially in shock.
The feature everyone else missed: a built-in calendar ring that stops food waste before it starts.
Vacuum bags turn berries to puree. DAYSEAL keeps raspberries intact.
$56 wasted every week. $200 to fix it. The ROI speaks for itself.
Watch the left one go
Same fruit, cut the same morning, same shelf. Left in an ordinary sealed container, right in DAYSEAL.
Both look like food. This is the day every container brand takes its photo.
How long it stays food
Refrigerated, ordinary container against a vacuum container. Published guides plus our own kitchen. Directional, and the point is the gap.
The part that does the work
"Airtight" is not the claim
-
Airtight only stops the air coming in. Close an ordinary 2 litre box over half a lettuce and you have sealed 1.5 litres of air in with it. A fifth of that is oxygen, and it is what does the damage.
-
Oxygen browns the cut face. Cut produce releases an enzyme that reacts with oxygen. No oxygen at the surface, no reaction.
-
Oxygen strips the vitamins. Temperature and oxygen are the two recognised drivers of vitamin C loss. Refrigerated raw spinach lost 94% of its vitamin C in seven days. Broccoli, 68%.
-
Oxygen turns the nuts and the coffee. Rancidity is oxidation. It is why almonds taste like cardboard three weeks in.
-
The moulds need it too. The ones that ruin food in a fridge are aerobic. Take the oxygen down and they slow down with it.
-
So we did not build a better lid. We built a way to take the air out. Six seconds, with a pump that lives on top of the box.
I've bought produce keepers before and they did nothing, so I was ready to be annoyed. The bag of spinach I opened last Sunday is still green today and today is Friday. I actually checked the date on the lid twice because I didn't believe it.
Fill it. Press it. Turn the dial.
About eight seconds, and no cable anywhere near the counter.
Fill it, leave a finger
Food in dry, headroom at the top, lid pressed down until it clicks flat.
Press the pump on top
Sit it over the valve and hold the button. It stops itself when it is done.
Turn the ring to today
The ring around the valve is the day you sealed it. No guessing on Thursday.
One lid. Four jobs.
Most of this product is a plastic box, and plastic boxes are a solved problem. All of the engineering is in the 3 mm of lid above the food.
-
The valve
Press to lock the vacuum in. Pull to break it.
No twisting, no lever, nothing that needs a spare hand while you are holding a bowl.
-
The date dial, 1 to 31
A ring of numbers around the valve. Turn it to today.
The vacuum buys you the days. The dial is how you know you still have them.
-
The double silicone seal
Two lips, not one. It holds a vacuum, and it holds soup on its side in a bag.
The ring lifts out for washing, and it is replaceable.
-
No hinges
Hinges are what snaps on a cheap container. Same place, usually year two.
There are none here. Press to lock, lift to open.
-
The ribbed clear body
You can see what is in it from across the kitchen.
Food you can see is food you eat, which does more for waste than most people expect.
The date dial sounds like a gimmick until you use it. Half of what I used to throw away wasn't even bad, I just couldn't remember when I made it, so out it went. Now I know.
The part nobody says out loud
Your family eats what survives to Thursday
-
You do not choose Thursday's dinner on Sunday. You choose it on Thursday, out of whatever is still good. The gap between those two is the whole problem.
-
Sunday you is generous. Fresh fish, the good berries, herbs for the recipe you found. You pay for that up front.
-
Thursday you is working with what is left. Spinach slimy, peppers soft. So it is pasta again, or the freezer, or the app.
Not because you gave up. Because the fresh food did not make it that far.
-
Food that lasts to Thursday gets eaten on Thursday. Not motivation. Not discipline. Not a meal plan. Availability.
-
And it is still worth eating when it gets there. Oxygen does not only spoil food. It degrades it the whole way down.
Slow that and Thursday's vegetables are closer to the ones you bought.
-
Which is why this is not a storage product. It is the gap between the food you buy and the food you eat, and that gap has been going in the bin.
What the professionals say
Three trades, three reasons for the same box.
Half of what my clients throw out was never spoiled. It was undated, and nobody gambles on a Tuesday. A dial on the lid fixes the part of food waste that has nothing to do with freshness, and the vacuum handles the part that does.
Every professional kitchen vacuum-seals its prep and dates it. Not because it is fancy. Because oxygen is the enemy and a label is the law. This is that, for a home fridge, without the big and expensive machine on the counter.
Airtight is a marketing word. What matters is the oxygen you sealed inside with the food. Pulling it out is the one home method that changes the chemistry. And it still lives in the fridge, which this page says out loud.
Sent to us from real fridges
-
Day 8 raspberries
"No furry one. That is the whole review."
-
Spinach, Sunday to Friday
"Checked the date on the lid twice because I didn't believe it."
-
Cut peppers, day six
"Still crisp. Never happened in my glass containers."
-
The whole fridge
"Everything visible, nothing in a bag with the top rolled over."
What actually changes, week by week
No transformation story. This is what people tell us, in the order they tell us.
-
Week 1
The dial does this on day one, before the vacuum has proved anything. Every box tells you when it went in.
You stop guessing
You bin less food that was never bad. It is a large share of it.
The fridge stops smelling
Of whatever the strongest thing in it happens to be.
-
Weeks 2 to 4
Where the vacuum shows up. At the end of the week, not the start.
Thursday changes
Something fresh is still there to cook with on Thursday.
No more panic cooking
You stop cooking things on Tuesday just to save them.
One less mid-week shop
The trip you used to make on Wednesday for one thing.
-
Month 2 and after
The change nobody predicts, and the one they mention most.
You buy differently
The good stuff, without the argument in your head about whether half of it gets wasted.
The shop gets smaller
And the food in it gets a little better.
A month without a wasted punnet
You notice it because it used to be every week.
And then we read the papers.
What your fridge throws away
The EPA put a price on household food waste in 2025: $728 per person, per year. Move the two sliders. We are not claiming you keep all of it. Pick the share you believe.
EPA, Estimating the Cost of Food Waste to American Consumers, April 2025. The set price is the one selected above. Savings depend on what you buy and how you use the boxes.
Get the complete setThe set costs less than five weeks of the bin
Three places the money comes back
The EPA puts household food waste at about $56 a week for a family of four. We are not claiming we eliminate that. Here is where it actually comes back.
The produce you already bought
Produce is the largest category of household food waste by volume, ahead of dairy, meat and grains combined. It is also the most expensive thing in the trolley per calorie.
Getting a bag of spinach from Wednesday to Sunday is not a small saving repeated. It is most of the saving.
The meal you were going to order instead
When nothing in the fridge is usable on a Thursday, dinner gets bought instead of cooked.
One avoided delivery a week is more than most people expect. It was never a budgeting problem. It was a supply problem.
The half you bin because you cannot remember
A real share of what leaves your fridge was never spoiled. It was undated, and you were not going to gamble on it.
The dial ends that on day one, before the vacuum has proved anything.

The questions we get most
Does it actually work, or is this the produce keeper I already own and hate?
Does it actually work, or is this the produce keeper I already own and hate?
Different mechanism entirely. Consumer Reports tested seven produce keepers against ordinary supermarket clamshells and found none of them much better.
Read what those containers were doing: managing humidity, through vents. A vent is a hole. Not one of them removed oxygen, which is the variable that drives browning, vitamin loss, rancidity and mould.
If a keeper disappointed you, it was fighting the wrong thing.
How long will my food actually last?
How long will my food actually last?
Days longer, and it depends on the food. Vacuum storage is documented to extend shelf life up to five times depending on the item, and hard cheese behaves nothing like raspberries.
We will not print a number for lettuce, because anyone who does is guessing.
What we will say: the difference shows up in days, not hours, and it shows up at the end of the week rather than the start.
Do I still have to refrigerate?
Do I still have to refrigerate?
Yes, always. Removing oxygen slows spoilage. It does not replace cold, and low oxygen storage at room temperature carries its own risk.
Anything that needed the fridge before needs it now. This buys you time inside the fridge, not outside it.
Is the pump included, or is that the catch?
Is the pump included, or is that the catch?
Included in every set. The most common complaint in this category is discovering the pump is sold separately after you have bought the boxes.
Cordless, USB rechargeable, one button, and it stops itself when the box is done.
Is the plastic safe?
Is the plastic safe?
Food grade PP body, PET lid, BPA free. Top rack of the dishwasher, freezer safe.
The silicone seal lifts out, so you wash it properly rather than hoping.
What if the seal stops holding?
What if the seal stops holding?
We replace it. Silicone is the wear part on every vacuum container ever made, and pretending otherwise would just make us the next brand you stop trusting.
Ours lift out and are replaceable. A failure inside the first year is on us, and the 60 day guarantee covers you regardless.
Will these fit my fridge?

Three of the seven are 7.5 cm tall, which clears a standard shelf. The largest is 27.8 x 16.7 x 13 cm. All seven sizes are listed in What is in the set, up in the product details.
They stack, and the lids sit flat because there are no hinges sticking up.
What foods should you not vacuum seal?
What foods should you not vacuum seal?
Whole fruit that is still ripening. Sealing in its own ethylene speeds it up rather than slowing it down: bananas, pears, peaches, tomatoes, whole avocados.
Raw mushrooms and raw garlic are on every food safety list for low oxygen reasons. Soft fresh cheeses are best kept short. Cut avocado, cooked food, hard cheese, prepped vegetables, leafy greens, berries, nuts, coffee and cured meat are all straightforward.
Does vacuum sealing keep nutrients in food?
Does vacuum sealing keep nutrients in food?
It addresses one of the two main causes of loss. Temperature and oxygen are the recognised drivers of vitamin C degradation. Refrigeration handles the first. Low oxygen storage handles the second.
Published figures on air stored refrigerated produce are stark: 94% of vitamin C lost from raw spinach over seven days in one review, 68% from broccoli. Nothing stops the clock. Slowing it is worth doing.

I've bought produce keepers before and they did nothing so I was ready to be annoyed. Opened a bag of spinach last Sunday and it's still green and it's Friday. Checked the date on the lid twice because I didn't believe it.
The date dial sounds like a gimmick until you use it. Half of what I threw away wasn't even bad, I just couldn't remember when I made it.
raspberries. eight days. no furry one. that's the whole review
Pump is quiet and it stops on its own so you're not standing there guessing. No cable on the counter which was the thing I was worried about.
Works really well but read the bit about not overfilling, I ignored it twice and wondered why the lid kept popping. My fault, it's right there on the page. Once I left some space at the top it's been perfect.
Fridge doesn't smell like whatever the strongest thing in it is anymore. Didn't expect that to be the thing I noticed first.
Does the job
Bought it for meal prep, ended up using it mostly for produce. Cut peppers and celery are still crisp on day six which never happened in my glass containers. The big one holds a whole batch of chilli.
Took me two goes to get the seal right, I wasn't pressing the lid flat first. Once you've done it once it's automatic. Worth mentioning because I nearly returned it on day one.
honestly the fridge just looks better 🙏 everything visible, nothing in a bag with the top rolled over
Coffee and almonds. That's what I bought it for and both taste right weeks later. Wife uses it for everything else.
Heads up, don't put whole bananas or tomatoes in these, it makes them go faster not slower. That's explained on the page and I skimmed past it. Everything cut or cooked has been great.
Three of us and we've gone from a bin bag of produce a week to almost nothing. Paid for itself somewhere in the first month, I stopped counting.
Six weeks in, seals still tight, dishwasher hasn't warped anything. The thing I'd tell someone buying is get the bigger set, I started thinking three would be enough and immediately wanted more.
