Unpacking

Alwe can be hung on the wall - like a normal picture. The algae picture is an air purifier that can be used in any interior. Here Alwe uses natural algae to remove pollutants from the air and release oxygen.

Alwe Bewässerung

Fill with water

The suitably designed frame of the algae image promotes air circulation and provides optimal watering through a water tank at the back. The tank should be refilled with water every 2-3 weeks. A suitable bottle is included in the delivery, an access to the tank is integrated in the frame.

Hang up

Das Algae picture entfernt schädliche Luftschadstoffe aus ihren Innenräumen. Algen brauchen keinen speziellen Untergrund – keine Erde. Sie nehmen alle Stoffe aus der Umgebung auf und entfernen neben CO2 auch Stickoxide, Feinstaub und andere Gase. Damit ist das Algae picture Pflanzen und Moosen überlegen.

Die Reinigungsleistung für ein Algae picture ist auf einen Raum von bis zu 25 m² ausgelegt. Es fallen keine Stromkosten an.

Become a climate saver

The climate catastrophes of recent years are clearly related to human-induced emissions. Emissions from energy generation and the operation of technical facilities are particularly intense. Therefore, set an example for the appreciation of resources by using a technology that does not require external energy and instead relies on the mechanisms of nature.

This is what they get

Practical
Framework concept

In order for the algae to find optimal conditions, we have optimized our frame through intensive research. This provides the living conditions for the algae and the air circulation for the best possible air purification.

Schlechte Luft Feinstaub

Biological
healthier air

The heart of Alwe consists of a living microalgae biofilm. This filters air pollutants from the passing air and breaks them down. 
One Alwe can bind 30-50% of the air pollutants of a 25m² room. 

Microalgae are unicellular microorganisms that belong to the class of phototrophic organisms, i.e. they carry out photosynthesis. This means that microalgae, just like plants, use light to bind carbon dioxide and release oxygen.

Alwe - The algae image uses specially selected microalgae, which are found in nature especially under stones. As a result, these organisms are adapted to be active even under very difficult light conditions - such as those we find in our interiors - and to carry out effective photosynthesis, among other things. For this purpose they have developed extraordinary photosystems, which are clearly different from those of plants.

Microalgae have a more flexible metabolism than plants, for example, and can therefore break down a large number of pollutants.

The current dimensions of Alwe50 are 50x50x5cm. The weight is 1.2 kg when empty and about 1.5 kg when filled.

Biologisch korrekt ausgedrückt handelt es sich bei den Algen, um Blaualgen also Cyanobakterien. Diese sind an Schwachlicht angepasst und besitzen spezielle Pigmente, welche die Photosynthese noch bei gerinsten Lichtstärken ermöglicht. Das macht Mikroalgen-Biofilme effizienter als Pflanzen und auch noch zu Luftverbesserern an Orten, wo Pflanzen gnadenlos eingehen. 

In investigations with the Federal Institute for Materials Research and Testing and the Technical University of Berlin, we have also discovered that microalgae biofilms can effectively bind air pollutants that are hazardous to health, such as nitrogen oxides and fine dust.

Initial tests at the Federal Institute for Materials Research and Testing also point to the reduction of volatile organic chemicals (VOCs) escaping from paints and building materials. Microalgae have a more flexible metabolism than plants, for example, and can therefore break down a large number of these pollutants.

Microalgae need light for their metabolism. Our algae picture is therefore best suited for rooms that are at least partially exposed to the sun.

However, please avoid attaching Alwe to surfaces that are often exposed to direct sunlight. If there is too much sunlight, more water will evaporate and the microalgae may start to break down their photo systems. The result is the fading of the biofilm. Should this happen, do not panic: Just leave Alwe in a shady place for some time and the biofilm will regenerate.

When designing Alwe, it was particularly important to us to keep the handling simple and manageable. That's why there is a small water tank in each Alwe, which needs to be refilled approximately every two weeks.

Yes, Alwe consists of living algae which adapt to the local light conditions. In shady areas the algae take on a deep green colour, as the micro-algae accumulate more pigments to absorb light more effectively. In semi-shade areas, the micro-algae need less pigments for successful photosynthesis and thus get a rather juicy and natural green colour.

In direct sunlight there is an overflow of energy in the algae. Under certain circumstances, this may cause the algae to actively break down their photo systems. The result is a colour change to light green or yellowish.

Algae films have not yet been researched in the long term, as these materials are completely new. However, we have not been able to identify any time limits in our previous R&D projects. Some of our algae films are already 4 years old and still healthy and productive, which is even more important. As algae films are living materials, no general statement can be made about their lifetime, as this obviously depends on care and local conditions. As far as we know, however, our biofilms are very robust, making them suitable even for users with brown rather than green thumbs.

With the purchase an Alwe we guarantee a minimum service life of 6 months. If problems occur within this period, you can return your Alwe without any problems and have it replaced by us.

Even after this period of 6 months you can of course always have your Alwe checked by us or you can try out one of our new biofilms. Please feel free to contact our service team.

In interiors, lighting in particular differs from natural light. Even with perceived bright interior lighting, the photosynthetically activating radiation is very low. This is because normal indoor lighting lacks the red and violet components of natural light that most plants need for photosynthesis. The microalgae biofilms we use, on the contrary, have special pigments that enable them to use light outside the red and violet spectrum for photosynthesis.

In addition, microalgae do not have roots or a stem and are therefore metabolically more effective compared to plants. 

Our carefully cultivated microalgae belong to the so-called safety level 1, which describes organisms that are unlikely to have a negative effect on health. This means that they are not dangerous to animals, humans, plants or water and can be used without restrictions. Organisms from the food industry such as cultures of yoghurt or baker's yeast also belong to this safety class.

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".
