 Alwe is an eco-efficient wall decor. The algae picture brings life to your wall - space-saving and easy to clean. In the heart, Alwe accommodates a living microalgae biofilm, which as an air purifier that actively absorbs air pollutants and produces oxygen. A green eye-catcher for your interior.


Alwe - The algae picture

With our algae picture we offer a completely new concept to animate grey living spaces. With innovative microalgae film technology, rooms and especially walls can be used more effectively.

Function meets design and the green superpowers invigorate grey surfaces with unique aesthetics. Alwe thus offers exclusive design and at the same time creates a pleasant room climate. 

Furthermore, Alwe is:

- Easy to clean, as the water tank only needs to be refilled every 2 weeks

- A sustainable and climate-friendly product

- A symbol for a more environmentally conscious and greener future


By purchasing our Alwe air purifier, you are actively supporting research into microalgae to reduce air pollutants and produce environmentally friendly energy sources..

ALWE is unique and lovingly handcrafted for you.


Where does the name Alwe come from?

The name "Alwe" is a hybrid of the purely descriptive term "algae wall" and the English emotional term "to awe". "Awe" refers to a feeling of amazement and admiration. By the fusion of both terms the neologism "Alwe" is created, which symbolically stands for our fascination for one of the oldest life forms of this planet - micro algae.

What are Alwe's measurements?

Die aktuellen Maße unseres Algenbildes betragen 50x50x5cm. Das Gewicht beträgt 1,2 kg im leeren und etwa 1,5 kg im gefüllten Zustand.

How does Alwe improve air quality?

We already know that the algal biofilms have a very effective CO2-Assimilation. verfügen. Alle photosynthetischen Organismen verfügen über zwei Stoffwechselwege.

On the one hand, there is photosynthesis, in which CO2 is bound by light energy and Oxygen produziert wird. Auf der anderen Seite steht die Zellatmung, die bei Dunkelheit bzw. bei niedrigem Licht die aufgebaute Glucose als Energieträger verstoffwechselt. Dieser Prozess heißt auch Respiration und setzt unter Sauerstoffverbrauch CO2 frei.

Die Lichtstärke bei der ein Gleichgewicht zwischen Respiration und Photosynthese herrscht, also genau so viel CO2 gebunden wie freigesetzt wird, nennt sich in der Biologie “Lichtkompensationspunkt”. Durch die adaptierten Photosysteme von Mikroalgenbiofilmen liegt dieser Punkt jedoch niedriger als bei Pflanzen, sodass selbst bei schwachen Licht noch die CO2-Fixierung durch Photosynthese überwiegt. Das macht Mikroalgenbiofilme effizienter als Pflanzen.

In Untersuchungen mit der Bundestanstalt für Materialforschung und der Technischen Universität haben wir auch herausgefunden, dass Mikroalgenbiofilme effektiv gesundheitsgefährdende Luftschadstoffe, wie beispielsweise Stickoxide und Feinstaub binden können.

Ebenfalls weisen erste Versuche an der Bundesanstalt für Materialforschung auf die Reduktion flüchtigen organischen Chemikalien (VOCs) hin, welche aus Lacken und Baustoffen austreten. Mikroalgen verfügen über einen flexibleren Stoffwechsel als beispielsweise Pflanzen und können so eine Vielzahl von Schadstoffen abbauen.

Where do I hang my Alwe most effectively?

Microalgae need light for their metabolism. For this reason, rooms in which the sun shines at least partially are best suited for our algae image.

Please avoid attaching Alwe to surfaces that are exposed to long periods of direct radiation. Too much natural light causes more water to evaporate and the microalgae photosystem may deteriorate. The result of this can be a gradual fading of the biofilm. If this happens, don't panic: Simply expose Alwe to a shady place and the biofilm should regenerate itself again over some time.

How much maintanance does Alwe require?

When designing Alwe, it was important to us to keep the handling and care of Alwe simple and manageable. Every Alwe picture has a small water tank that requires a refill approximately every two weeks.

Does the colour of Alwe change over time?

Yes, as a living algae image the algae adapt to the light conditions prevailing in the space it is placed. In a rather shady area the algae often takes on a deep green colour, as the microalgae accumulate more pigments to absorb light more effectively. In the semi-shade the microalgae need less pigment and generally become slightly lighter and fresh natural green colour.

In direct sunlight, there is an excess of energy in the algae. As a result, the algae may actively degrade their photo systems. The result is a colour change from light green to yellowish.

Microalgae need light for their metabolism. For this reason, rooms in which the sun shines at least partially are best suited for our algae image.

What are microalgae?

Microalgae are single-cell microorganisms that belong to the class of phototrophic organisms - i.e. carry out photosynthesis. This means that they, like plants, bind carbon dioxide with the aid of light and release oxygen. In our algae picture "Alwe" there are specially selected microalgae, which can be found in nature under stones. As a result, these organisms are adapted to effectively carry out photosynthesis even under very difficult light conditions, such as those found in our indoor spaces. For this purpose they have developed special photosystems which distinguish them from plants.

How long does a biofilm live?

Biofilme sind noch nicht langzeitlich erforscht, da diese Materialien völlig neu sind. Wir haben jedoch bei unseren F&E-Forschungen noch keine Limitation gesehen. Einige unsere Biofilme sind bereits knapp 4 Jahre alt und immer noch gesund und vor allem produktiv. Da es sich um ein lebendiges Material handelt, kann man leider keine pauschale Aussage dazu treffen, da die Lebensdauer selbstverständlich auch von der Pflege und den örtlichen Gegebenheiten abhängt.

Soweit wir wissen, sind unsere Biofilme sehr robust, sodass sie sich selbst für Anwender mit eher braunen als grünen Daumen eignen.

Wir garantieren beim Kauf eines ALWES eine minimale Lebensdauer von 6 Monaten. Sollten Sie irgendwelche Probleme innerhalb 6 Monate feststellen, können Sie Ihren Alwe problemlos zurückschicken und kostenlos Auswechseln lassen.

Nach den 6 Monaten können Sie natürlich auch jederzeit Ihren Alwe von uns überholen lassen und einen unseren neuen Biofilme ausprobieren. Setzen Sie sich einfach mit unseren Service-Team in Verbindung.

Why are microalgae more effective than plants?

Interior lighting in particular differs greatly from natural light. Even with perceived bright interior lighting, photosynthetic active radiation is very low. With normal interior lighting, the red and violet components of the natural light required for photosynthesis are absent.

The microalgae biofilms we use have special pigments that allow you to use light outside the red and violet spectrum for photosynthesis. Furthermore, microalgae have no roots, leaves or trunks. Microalgae are metabolically more effective in the utilization of material flows. This makes them more effective than plants.

Can Alwe break and the microalgae spread?

Alwe is thoroughly checked for leaks before shipment. We can therefore guarantee that there are no leaks before hanging Alwe.

Our algae picture is very similar to a picture within a picture frame. This means that Alwe can break if applied incorrectly.

The algae used in the Alwe are natural and harmless. They are immobilised on a surface and can easily be collected and disposed of via bio bin or normal household waste.

Alwe has an artificial ecosystem that the microalgae need to live. Outside of Alwe, the microalgae are not viable and cannot spread or similar.

Are the microalgae safe?

All our carefully cultivated microalgae are organisms that belong to the so-called safety level 1. This describes organisms in which it is unlikely to have a negative effect on health. They are therefore neither dangerous
for animals, humans, plants or water and applicable without conditions. This same safety class also includes organisms from the food industry, such as yoghurt, baker's yeast or sauerkraut cultures.

Our biofilms are produced under sterile conditions. Only when the biofilms have formed their characteristic protective skin layer are they released by us for usage in the algae image "Alwe".
