Air Up promises flavored water using only scent – ​​without sugar, without calories, and without any additives in the water itself. In Germany, the brand has become one of the best-known hydration startups and is primarily marketed as an alternative to soft drinks and sugary beverages.

What is air up?

air up is a drinking bottle system that combines tap or mineral water with so-called scent pods, creating the impression of flavor solely through smell. The real innovation is that no flavorings, sweeteners, or colorings are dissolved in the water – it remains chemically normal water.

air up was founded as a start-up in Germany and is now one of the most successful water bottle brands in German-speaking countries. The system is aimed primarily at people who want to drink more but find the taste of plain water boring.

How does air up work technically?

The way air up works is based on retronasal olfactory perception – that is, the smell we perceive through our nose when odor molecules rise from the mouth into the nasal cavity. Our brain interprets these olfactory signals as taste, even though nothing in the water itself changes.

When drinking through the integrated straw, air is drawn through the aroma pod, absorbs the flavor from a fleece-like carrier layer, and enters the mouth along with the water. Upon swallowing, the flavored airflow rises into the nasal passages, creating the sensation of drinking a flavored beverage.

Structure of the air up system

air up consists of three central components: bottle, straw and fragrance pod.

• The bottles are made of BPA-free plastic or steel and are available in sizes between approximately 650 and 850 milliliters.

• A sturdy, integrated straw transports water and scented air simultaneously into the mouth.

• The pods sit above the mouthpiece, contain plant-based flavors in a porous structure and can “scent” several liters of water.

To use, fill the bottle with water, attach the pod to the mouthpiece, and pull it slightly upwards to activate it. Pulling the pod back down allows you to drink plain, unscented water.

air up and health: Is it really “just water”?

According to the manufacturer and independent tests, the water in the bottle remains chemically unchanged, as no liquid flavorings or sweeteners are added. Studies by German research institutes have confirmed that the drink remains water and that air up can be classified as safe.

The flavorings in the pods are derived from plant-based ingredients, but are inhaled as an airflow rather than a liquid. This appeals to many users because they subjectively experience “flavor” without consuming the sugar, calories, or acids of traditional soft drinks.

Why is air up so popular in Germany?

Germany is considered a “tap water nation,” as a large portion of the population regularly drinks tap water. In a study by the Techniker Krankenkasse (a German health insurance company), approximately 63 percent of respondents stated that they drink tap water daily; the percentage was even higher among younger people .

air up addresses this very issue by combining ordinary tap water with a unique taste experience, while simultaneously differentiating itself from the image of classic soft drinks. Media coverage and significant investments – including from major beverage companies – have further accelerated the brand’s recognition.

air up UK: Availability for German users with a UK connection

In addition to the German market, air up also sells its products in Great Britain via a dedicated UK shop page. There you will find special product and pricing structures for “air up UK”, including local service and pods priced in pounds.

The UK offering includes a wide range of pods and starter kits tailored to the needs of the British market. For German users residing in or staying in the UK for extended periods, ” air up UK ” can therefore be a convenient source, while the core of the system, with its retronasal fragrance principle, remains identical.

What flavors are available?

air up offers a wide range of pods, which can be broadly categorized into fruity, soft drink-inspired, and mocktail flavors. Many varieties are available as individual pods or in variety packs that combine several flavors.

Typical fruity flavors include Wild Berry, Peach, Apple, Lemon, Lime, Raspberry-Lemon, and Blackcurrant. In addition, there are soft drink-oriented varieties such as Cola, Cherry Cola, Lemon Lime Soda, and Peach Ice Tea, as well as more exotic or limited-edition flavors like Guava Crush, Dragonfruit-Lychee, and special shake flavors.

How does air up perform in tests and reviews?

User reviews from tech and lifestyle websites often mention that the bottle is easy to assemble and that activating the pods is intuitive after a short familiarization period. Many testers emphasize that the subjective taste experience depends heavily on individual smell preferences and personal sensitivity to aromas .

In video reviews, air up is often praised because it helps some users drink significantly more water and reduce their consumption of soft drinks. Criticisms usually concern the price of the pods, the sustainability issue of disposable pods, and differing expectations regarding the intensity of the perceived flavors .

Sustainability, material specifications and criticisms

Official information emphasizes that the pods and bottles are made from BPA-free materials and that certain components are recyclable. The pods themselves use recyclable plastics and plant-based flavors, but are consumable products that need to be replaced after a few liters of water.

In the past, the company faced criticism for its ambiguous use of terms regarding “recycled” versus “recyclable” materials, which it corrected after being alerted by a German journalist. For sustainability-minded consumers, the trade-off between increased hydration and the additional resource consumption caused by pod packaging remains a relevant consideration.

air up compared to classic drinks

Compared to sodas and many ready-made iced teas, air up offers a significant advantage in terms of sugar and calorie content, as it consists solely of water. At the same time, unlike highly acidic soft drinks, it is less damaging to tooth enamel because no additional acid is introduced into the water.

Compared to conventional water bottles, air up involves additional costs for pods and a more complex product chain. The added value lies primarily in the sensory experience and the motivation to drink more, which can be crucial, especially for people with poor hydration habits .

Who is air up particularly suitable for?

Air Up is particularly suitable for people who know they should drink more, but have difficulty drinking plain water. Parents also sometimes see the system as a way to wean their children off sugary soft drinks without completely forgoing the taste experience.

For users who already enjoy drinking water and primarily focus on minimalism and waste reduction, the system offers less additional benefit. However, those who frequently consume soft drinks can use air up as a way to gradually reduce their sugar intake.

air up UK vs. Germany: What should German users be aware of?

The main differences between the German and British versions of air up are in language, pricing, and available bundles. The UK site presents pods and variety packs in pound prices and sometimes with locally adapted product names or promotions, while the technical structure of the system is identical.

For German users who live in or frequently travel to the UK, ordering via “air up UK” may be logistically more practical than ordering from Germany. Those who live permanently in Germany, on the other hand, usually benefit from the established distribution channels and local customer service available here.

Conclusion: Is air up worth it?

Air up is not a miracle cure, but a technically clever system that uses retronasal olfactory perception to make water appear subjectively flavored. For many people in Germany, this could be a practical strategy to drink more while simultaneously reducing their consumption of sugary soft drinks and juices.

Whether air up is worthwhile in everyday life depends primarily on individual drinking habits, price sensitivity, and sustainability requirements. Those who find plain water unmotivating could find air up to be a viable compromise between a pleasant taste experience and safe hydration – both in Germany and through services like air up UK.
