How are your products sustainable?
How are your products sustainable?
Based on the idea of MAXIMUM TASTE MINIMUM WASTE, we develop products that make sustainable living easier and reduce plastic and food waste (Minimum Waste).
But it takes more to get people to change their behaviour. Our approach is to let those same products also bring fun and pleasure, by always making it easy to enjoy good food and drinks (Maximum Taste).
Combine the reduction in food and packaging waste with the significant food cost savings and it immediately becomes clear why Airtender products are sustainable. Of course, we also contribute through the way in which we produce our products.

Vacuum Saving & Preparing (General)
Why can I store food longer with vacuum?
Why can I store food longer with vacuum?
Food loses quality when it’s exposed to air. It’s the reason that, for example, cookies and cereals lose their crispiness. That process is called “oxidation”. So, by removing the air from a jar, you slow down oxidation and your food stays fresh and full of flavour and nutrients.
The second reason that food spoils is bacteria. For example, when strawberries and blueberries get soft and moldy. Most bacteria need oxygen to work. So, remove the air and, again, you will slow down loss of quality.
Although air is the most important factor, there are more factors that contribute to spoilage, such as temperature and sunlight. And, of course, the condition of the food before storage and hygiene when handling and preparing food.
Does vacuum storage work for all foods?
Does vacuum storage work for all foods?
Vacuum storage will extend shelf life for most types of food. That doesn't only apply to dry foods like cookies, nuts and cereals. Vacuum also works for fresh foods such as fruit salads and fresh strawberries, blueberries and even guacamole.
As a rule of thumb, vacuum will keep food fresh up to 5x longer, when compared to conventional storage. An example: when you buy strawberries, they usually start to lose their qiuality after about two days. Stored in a vacuum container (in the fridge!) you will extend freshness up to 1.5 weeks.
Please note that there are more factors that contribute to food aging and spoliage, inclusing temperature and the condition of the food before storage. Maintain good hygiene and always adhere to safe food handling guidelines.
Some foods are not suitable for vacuum storage. For more information, please read our compact food storage guide.
What do you mean by "non-toxic?"
What do you mean by "non-toxic?"
When you save food in plastic containers and bags, there is always a risk of chemicals slowly leaching into your food. Especially when those containers are routinely washed in the dishwasher. Yes, the materials may have been labelled as ‘food approved’, but the effects over time when directly in contact with food are still uncertain.
Apart from the chemical problem, there is evidence that tiny pieces of plastic called “microplastics” and “nanoplastics” separate from containers and lids into your food. These plastic particles end up in the body, which poses severe health risks.
Glass, however, does not leach chemicals and does not disintegrate into your food. It has been a safe and trusted way of storing and preparing foods for centuries. And of course: 100% recyclable and sustainable!
How many times can I reuse a glass jar?
How many times can I reuse a glass jar?
Glass jars can be used indefinitely, as long as they aren't damaged. Since the Nanostoppers and Airtender lids are also reusable, you can keep vacuum savin, marinating, pickling and more, as lang as you want!
One thing to keep in mind is that metal lids may not last forever. Since the standard metal lids have not been manufactured for endless use, the built-in seal might start to lose it's airtight function. Luckily, you can use any twist-top jar, so either replace the entire jar, just the lid or select a reusable Airtender jar and you're good to go. Just don't forget to recycle any jars and lids that you don't need anymore :)

How do I marinate and pickle with vacuum?
How do I marinate and pickle with vacuum?
Pickling and marinating with vacuum works largely in the same way as the “traditional” technique. You place your (cut) ingredients in the marinade, liquid or brine, so that they can absorb the flavours.
The big difference is that, with a vacuum, you ensure that the flavouring process is accelerated. How exactly does that work? The vacuum ensures that the fibers of the vegetables or meat are slightly pulled apart and any air and juices are also extracted. This creates space for the marinade or liquid to penetrate the food faster and deeper.
When pickling and also infusing (for example making fruit flavoured water), something extra happens. Flavours and aromas are also extracted from your vegetables or fruit, enabling them to quickly mix with the liquid around them. As a result, an exchange of intense flavors is created.
For inspiration on what to marinate, pickle or infuse, please visit our recipe page.
Can I ferment in any jar?
Can I ferment in any jar?
Absolutely, but every jar will work a bit differently.
If you would like to ferment with twist-off jars or mason jars, you can use the Airtender Lid Punch to make a perfect hole in metal lids. You will need to insert a "water lock" in the hole, so the fermentation gases can escape. This type of accessory can be bought in most (online) shops that sell canning accessories.
You can also use Clip Top Jars and traditional Weck-style jars with Airtender vacuum lids. The bonus is that you can kickstart the fermentation process by creating a vacuum in the jar. And use the same jar after fermentation to vacuum seal your food and keep it fresh up to 5x longer.
How fast can I infuse drinks?
How fast can I infuse drinks?
That depends on what you're infusing, but on average, vacuum can speed up infusion at least 5 times. For example, if you're making infused water, you could be done in 5 minutes in stead of at least 30.
And by using vacuum, more flavour and vitamins are extracted from the ingredients. So it's not only richer in flavour but also healthier. So why wait if you can enjoy a drink almost right away?
Do I have to use vacuum to infuse?
Do I have to use vacuum to infuse?
No, but using vacuum will let you infuse faster and taste more.
Can I also use the vacuum jars for pickling or marinating?
Can I also use the vacuum jars for pickling or marinating?
Yes, you can! It's in fact a very similar process to vacuum infusing.
The vacuum will "open up" ingredients to extract and exchange flavours. So, just like with vacuium infusions: faster results and more intense flavours!
Clip Top Jar Vacuum Lids
Which clip top jars are compatible with Airtender lids?
Which clip top jars are compatible with Airtender lids?
The Airtender vacuum lids fit the most commonly available size clip top jars, often referred to as "85"or "90". This means that they are compatible with multiple designs and brands, such as Bormioli Fido, Kilner and IKEA, as well as many private label brands.
Because of the large number of brands and jar designs, as well as the nature of glass production, it's always possible that lids do not properly fit certain jars. If you are uncertain about the compatibilty with our jars, please do not hesitate to contact us.
Alternatively, you can select any of the complete sets of jars with lids and Airtender vacuum pump.

What's the difference with traditional pickling?
What's the difference with traditional pickling?
Pickling in the traditional way is done by letting your vegetables or fruits ferment in a vinegar-like solution and/or brine, for a longer period of time. This results in the traditional sweet-and-sour taste (and also extends shelf-life). The only disadvantage is that this process usually takes quite some time.
Quick pickling with Airtender works by using vacuum. Take, for example, sliced cucumber or red onion. By placing them in a mixture of vinegar, sugar, salt and other ingredients in a jar under vacuum, you extract air and juices from the vegetables. You will clearly see the air bubbles while the vacuum is being created. This way, the vacuum quickly draws the pickling liquid into the vegetables, cutting down pickling time from hours or days into minutes.

Are the lids dishwasher safe?
Are the lids dishwasher safe?
Yes, the lids are dishwasher safe. For best cleaning, disassemble the lids by removing the silicone ring and the Nanostopper.
Glass Top Jar Vacuum Lids
What is the difference with the standard glass lids and seals?
What is the difference with the standard glass lids and seals?
The Airtender Glass Top Vacuum Lids are actually two part lids. They are the original glass lids , but with a high-grade silicone cover.
The unique cover not only transforms the glass lid into an airtight closure, but also adda a vacuum option. So you can use your Weck-style jars and carafes with lids for storage without rattling glass or loose seals and clips. To keep food and drinks fresh up to 5x longer, vacuum seal them with the same lids and an Airtender vacuum pump.
But even that's not all. Use vacuum with your jars and carafes to quickly marinate, pickle and infuse. Or use the Airtender lids with the original metal clips to use your jars for fermentations and the lids will automatically release fermentation gases.
Do I still have to use the metal fastening clips?
Do I still have to use the metal fastening clips?
The Airtender lids don't need the metal clips (or the original rubber seal) to close the jar or bottle.
The metal clips can however still be used with the lids, for example when you use your jars for fermentation.
Are the lids free of plastics?
Are the lids free of plastics?
Yes, the lids are made of glass and 100% high grade silicone.
Do I always have to use vacuum?
Do I always have to use vacuum?
The lids provide an airtight closure, so you won't have to use vacuum if you are using your jars and carafes for short-term storage. Vacuum will howerver keep your food and drinks fresh and full of flavour and nutrients for longer.
Vacuum will also speed up processes such as marinating, pickling and infusing
Are the lids dishwasher safe?
Are the lids dishwasher safe?
Yes, the lids are dishwasher safe. For best cleaning, disassemble the lids by removing the silicone cover from the glass lid.
Vacuum for Twist Top Lids
How does the Food&Wine Vacuum set extend freshness?
How does the Food&Wine Vacuum set extend freshness?
With the vacuum pump and Nanostopper, you can create vacuum in bottles and jars by removing air. By doing so, you also remove oxygen, which is one of the main elements that cause loss food spoilage and loss of flavour and freshness. Les oxygen means less oxidation, and therefore flavour and freshness will be preserved longer.
Please note that there are more factors that contribute to food aging and spoliage, inclusing temperature and the condition of the food before storage. Maintain good hygiene and always adhere to safe food handling guidelines.
Some foods are not suitable for vacuum storage. For more information, please read our compact food storge guide.
Is the Lid Punch safe to use?
Is the Lid Punch safe to use?
The Lid Punch has been designed to quickly and safely make a hole in metal twist-off and screw top lids. However, Like any other sharp kitchen tool such as a knife or scissors, you need to be mindful when using the Lid Punch.
Also, when removing the cut-out metal disc, keep in mind that the disc itself can be sharp. So always use a kitchen towel or cloth to remove it from the Lid Punch.
Just carefully study and always follow the instructions, and you will be punching holes in lids without any problems.
Can I also use Nanostoppers on plastic lids and/or jars?
Can I also use Nanostoppers on plastic lids and/or jars?
Plastic jars or jars with plastic lids aren't suitable for vacuum. They simply aren't strong enough to resist the deep vacuum level that Airtender creates and will collapse or even implode.
Can I really use any jar with vacuum?
Can I really use any jar with vacuum?
Yes, basically any airtight glass jar can be used to use with vacuum. Airtender provides solutions for twist-top jars, clip-top jars and glass top jars. Be sure to select the proper lids for each jar, and when using jars with the Airtender Lid Punch, make sure that you only use metal lids.
Plastic jars or jars with plastic lids aren't suitable for vacuum. They simply aren't strong enough to resist the deep vacuum level that Airtender creates and will collapse or even implode.
Importantly, we also don't recommend plastic jars because they aren't sustainable, and can be a health risk beacuse chemicals and microplastics can potentially get into your food.
Can I use all types of Mason Jars with the Lid Punch?
Can I use all types of Mason Jars with the Lid Punch?
If you are using a canning jar with a screw typemetal lid, then the Lid Punch will work to make a hole for the Nanostopper.
You can use one-piece mason-jar type lids, or the two part type with a plate and screw ring. Regular twist-off lids with metal lids are also fine.
How does vacuum saving work?
How does vacuum saving work?
When food is exposed to oxygen, it starts to age and lose quality. The results are loss of flavour, colour, flavour and nutrients. This process is called oxidation. It's what makes sliced apples turn brown, causes cookies and cereals to become stale and wine to go off.
By storing food and drinks in a jar, container or bottle and removing the air, you remove the oxygen inside. This prevents the food from reacting with the oxygen, thus slowing down oxidation.The result: food and drinks that stay fresh up to 5x longer!
Are metal lids dishwasher safe?
Are metal lids dishwasher safe?
Metal lids should not be washed in the dish washer, because dishwasher detergents can damage the lids and seals. Carefully handwash metal lids and thoroughly dry them, especially when you have made a hole with the Lid Punch.
Vacuum Wine Saving
How does vacuum wine saving work?
How does vacuum wine saving work?
When wine is exposed to air, it starts reacting with the oxygen in the air. Because of this "oxidation" the wine starts to lose flavour, aroma and colour. And, usually after a day of two or three, the wine loses so much quality that it becomes unpleasant to drink.
Since oxydation is the problem, removing the oxygen seems like the obvious solution - and it is! With Airtender vacuum wine savers, you pump out air from an opened bottle, sealing it with a Nanostopper stopper. This way, oxidation is slowed down and this will keep your wine fresh up to 5x longer! So, on average, in stead of lasting for 2-3 days, youw ine can stay fresh for weeks.
The science is quite simple, but really effective. That's why millions of people at home and in hospitality choose vacuum savers to serve wine by the glass and keep wine fresh for later.
How do I save leftover wine?
How do I save leftover wine?
Pumping air into wine will enhance aroma and flavour, but the opposite is also true: extracting air from a bottle will preserve the wine and keep it fresh up to 5x longer.
You can easily do this with one of the Airtender Vacuum Wine Saver sets: insert a Nanostopper and pump out the air to enjoy leftover wine any time you want. Shop Airtender Wine Savers here.
Can I also vacuum save sparkling wines?
Can I also vacuum save sparkling wines?
Vacuum stoppers won't work on sparkling wines for two reasons:
1) The gas that is released from the wine will cancel the vacuum over time
2) The vacuum will cause the gas to be extracted, so the wine will go flat
But keep a close eye on us, because we just might just develop the next-generation solution for sparking wine saving!
What is the difference with other wine savers?
What is the difference with other wine savers?
The working principle of traditional vacuum wine savers is the same: extract air from a bottle to slow down oxidation.However, the Airtender wine savers were developed to overcome a few important limitations of existing pumps and stoppers.
For cork & screw cap
The Nanostopper is the only vacuum stopper that properly works on bottles with cork and screw cap.
Horizontal storage
The Nanostopper is the first and only vacuum stopper that fits beneath a screw cap. This makes it the only shystem that allows you to store vacuum sealed bottles horizontally
Double vacuum indicators
The Airtender wine saver is the only wine saver that has a vacuum indication on the manual pump and the stopper. So you will always know when to stop pumping and that the bottle is properly vacuum sealed. The Electric Food&Wine Saver will automatically stop when the vacuum level is reached.
Non-toxic
The Nanostoppers have been made from premium silicone, whereas traditional stoppers are made from synthetic rubber.
Wine Aerators
How do Airtender Aerators work?
How do Airtender Aerators work?
Wine is a natural product and by exposing it to air, it develops its full aroma and flavor. One of the frequently used terms for this process is "to let wine breathe". Usually, this takes anywhere from 30 minutes to several hours.
When you aerate wine, you speed up this process, by actively adding air to the wine and forcing it to react with it. The "oxidation" of the wine involves chemical changes in the wine, which bring out the characteristic flavours of the wine, such as fruits and wooden tones. It also makes the wine smoother to drink and reduces the negative effects of sulfites and tannins.
Over the years, tools have been developed to facilitate the aeration process. The most common ones are glass decanting carafes and aerators to pour wine through. Unfortunately, these are vague, not very effective, notoriously difficult to clean and often clumsy or fragile.
With the Airtender Wine Aerator, you will aerate every glass of wine instantly and consistently. It will also give you full control of how much you aerate, so you can drink the wine exactly to your personal taste.
Is aerating really necessary?
Is aerating really necessary?
Wine is always a matter of personal taste. Some people enjoy drinking wine as-is, and that's just fine if you like that.
However, most wine lovers find that aerating opens it up, improving flavour and arome. Aerating also makes the wine smoother and easier to drink, softening tannins and reducing sulfites, elements that can make wine harsh and unpleasant to drink.
But again, it's up to you. Luckily, Airtender wine aerators are easy to use and work instantly, so you control how much you areate, and can experiment to find your perfect flavour!
How long does the aerating effect last?
How long does the aerating effect last?
The effect of a wine aerator is permanent, so onze you have aerated a glass or bottle, the unlocked flavour and aroma will remain.
Tip: with Airtender Wine Aerators, you can precisely control how much you aerate. Start with one or two "shots" and have a taste, and decide if you want to aerate more. This way, you can enjoy your wine to your specific taste. And serve wine for your guests just the way they like it.
Are the Airtender Aerators dishwasher safe?
Are the Airtender Aerators dishwasher safe?
Almost completely. The stainless steel tube and filter can be cleaned in the dishwasher or rinsed under the tap. The outside of the Air Pump should only be cleaned with a wet cloth.
For owners of a Wine Aerator PRO, the Vortex Aerator (the funnel) is also dishwasher safe.
Can I also aerate sparkling wines?
Can I also aerate sparkling wines?
Aerating sparkling wine, whether white or red, is not very common or recommended. This is because the process dissipates their signature bubbles and diminishes the lively mouthfeel.
Of course, wine is a matter of personal taste. So, should you enjoy sparkling wine to be a bit smoother (or just don't like very bubbly drinks), you can let it breathe for a while or very gently aerate it. This will reduce the excessive bubbles, allowing the wine to settle and develop so that you can better taste the wine’s textures.
So it all depends on your preferences.
What is the difference between the Wine Aerator and the Wine Aerator PRO?
What is the difference between the Wine Aerator and the Wine Aerator PRO?
With the Wine Aerator you aerate by the glass, while the Wine Aerator PRO will aerate an entire bottle in under 60 seconds.
So, depending on whether you are serving wine by the glass or by the bottle, you can choose which one suits you best.
Nanostopper
Can I use the same Nanostoppers for jars and bottles?
Can I use the same Nanostoppers for jars and bottles?
Yes, you can! The same Nanostopper works on wine bottles as wel as Airtender vacuum solutions for jars. With the exception of the glass top lids that do not require Nanostoppers to work.
How do I clean the Nanostopper?
How do I clean the Nanostopper?
You can clean them however you prefer: you can hand wash them with dish soap, but the Nanostoppers are also dishwasher safe.
Do make sure to avoid using any abrasive or aggressive chemical cleaning agents.
How do I know if a jar or bottle is vacuum sealed?
How do I know if a jar or bottle is vacuum sealed?
The Airtender vacuum pump will give you a signal when the bottle or jar is properly seals, beacuse you will here a popping" sound whenan appriopriate vacuum level is reached. For deeper vacuum, you can keep pumping after the signal.
When you use the Nanostopper, or one of our vacuum lids with the Nanostopper, you can always see when the jar or wine bottle is vacuum sealed because of the vacuum indicator: When the stopper sits flat on the lid or bottle.
How many times can I use a Nanostopper?
How many times can I use a Nanostopper?
The Nanostoppers have been engineered to be used countless times. And they are also dishwasher safe!
Cocktail Tools
Does the aerator replace a cocktail shaker?
Does the aerator replace a cocktail shaker?
With the cocktail aerator, you make cocktails using a different technique than with a shaker. So, the aerator is not a direct replacement of the shaker, but just a different way of making a premium cocktail. It also makes it possible to make a cocktail directly in the glass. Perfect for large numbers, or when you just want to make one cocktail without having to clean a lot of tools.
Do you prefer to use a cocktail shaker? Then use the cocktail aerator to cut down on shaking time and boost flavour and foam, just like in the Cocktail Shaker PRO.
Does the aerator also work for cocktails without foam?
Does the aerator also work for cocktails without foam?
Yes, it does. If you leave out the foaming ingredient (egg white, or vegan alternative foamers) the aerator will still mix and boost flavour, but without the permanent layer of foam.
How much faster can I make a cocktail?
How much faster can I make a cocktail?
That depends on the type of cocktail, but you can easily serve a cocktail in under 60 seconds.
Why is this important? Because it's nice to serve all of your guests a premium cocktail without having to wait forever.
Are the Cocktail Aerators dishwasher safe?
Are the Cocktail Aerators dishwasher safe?
Almost completely. The stainless steel tube and filter can be cleaned in the dishwasher or rinsed under the tap. The outside of the Air Pump should only be cleaned with a wet cloth.
The stainless steel cocktail shaker cups, jigger and strainer of the Cocktail Shaker PRO are all dishwasher safe.
How does the cocktail aerator work?
How does the cocktail aerator work?
The aerator works by diffusing air from the pump into millions of microscopic air bubbles. These bubbles get trapped in the cocktail ingredients, instantly creating a rich foam.This process also mixes the ingredients themselves and boosts flavour at the same time.
When you use the aerator in a glass, you can create a premium foamed cocktail without a shaker. When you prefer to shake, the aerator will maximize the amount of foam and flavour in the shaker. This means that you only have to shake a few seconds to get a fantastic result.
Troubleshooting
Why does my jar fail to vacuum seal/Why does the vacuum not hold?
Why does my jar fail to vacuum seal/Why does the vacuum not hold?
It's never easy to determine the exact cause, but we do offer the following tips and advice that solve practically all of these questions/issues:
- Always make sure that the pump is correctly centered and connected to the Nanostopper
- Make sure that the rim of the jar is clean. When crumbs or other materials get between the lid and the glass, this can cause air leaks.
- Check that the seal on the inside of the lid (around the rim) is not damaged. When the lid has some age, the seal could be deteriorated. So try a new(er) lid on the same jar.
- When using the Lid Punch: always make the hole in the center of the jar and avoid crossing any creases, bumps or other irragularities in the lid. Remove any labels from the top of the lid and make sure the lid surface is clean.
- Make sure that the lid is screwed on tight, but don't overtighten it since this can damage the seal.
- Although twist-off lids for the same brand or even between brands should be identical, there can always be slight differences. Try to use the lids that can with the jar.
If none of the tips above solve the problem, please let us know and we will be happy to help.
I don't hear a click after pumping. What am I doing wrong?
I don't hear a click after pumping. What am I doing wrong?
The most common reason for not hearing the vacuum indicator is that the pump is not entirely connected to the Nanostopper or vacuum lid. Try to keep the pump upright and centered on the stopper or valve lid. You should feel some increasing resistance when you are pumping.
Should you still not be able to create a proper vacuum or hear the indicator, please let us know. We're always happy to help with identifying any issues and make sure we can solve them.
My vacuum pump stopped working. It doesn't seem to create vacuum.
My vacuum pump stopped working. It doesn't seem to create vacuum.
In the rare cases we hear of something like this, it always involves a loose internal part. Because we work with sheltered workshops, it can unfortunately sometimes happen that the pump isn't sufficiently lubricated. This can cause a small cap on the inside to come loose after a while, causing the pump to run stiffly or stop working altogether. Fortunately, this is a very quick and easy fix by disassembling the pump and re-lubricating it.
This video shows you how to do this in just a few minutes.
Could you please try this and let us know if it solves the problem? We apologize for the inconvenience, and I hope you can use your Airtender pump again soon!
If this is a different defect, we'd also like to hear from you.
I see some rust around the hole that I have punched. What to do?
I see some rust around the hole that I have punched. What to do?
As with practically all jars with metal lids, in some cases, rust can form over a longer period of time. For example, with lids that haven't been dry or when there have been highly acidic ingredients in the jar for a long time.
While the rust itself is not harmful, we always recommend brushing superifial rust off and making sure that the lid is clean and dry before continuing to use it. If the rust is not only superficial and you're not be able to brush it off completely, then replace the lid. And don't forget to recycle the old one!
My clip top jar won't close when I use an Airtender vacuum lid.
My clip top jar won't close when I use an Airtender vacuum lid.
The Airtender Clip Top Jar Vacuum Lids have been designed to fit the most commonly available size of clip top jars - often known as size 90 (or in some cases 85).
We have tested many different brands of jars to maximize compatibility. However, it's practically impossible to test all existing types and brands of clip top jar.
Furthermore, variation in glass production or even changes in glass lid designs can happen over time. This can result in lids that do fit on the jar itself, but won't allow the glass lid to properly close (anymore).
Luckily, we also have complet sets of jars and lids available, so you can always be certain that everything will fit perfectly. Have a look at our assortment here.
