The water wall 

for home & office

Algae - Water Wall

Water wall meets algae

Decoration meets biological air purification

Produces oxygen and reduces CO₂

An algae wall takes up as much CO₂ up like a 20-metre-high tree, releasing oxygen into its surroundings. This process can also take place without natural light.


Unique eye catcher

Microalgae are not plants, have no roots or leaves and require no soil. The extraordinary aesthetics of the microalgae biofilm attracts attention and spreads a feel-good atmosphere. 

Binds particulate matter and other pollutants

Particulate matter, nitrogen oxides and harmful chemicals are absorbed and broken down by the microalgae. In addition, the water flow contributes to humidity regulation.

Measurement data refer to a study conducted by the Fraunhofer Institute. 



Data refer to measurements in a 25m² room.

Room cooling up to 2 °C

Due to the evaporation of water, the water wall cools the room air by approx. 2 °C (example picture: 29.5 °C to 27.5 °C).

Air humidification up to 15%

Algae water walls cause an increase in humidity from 38% to 53% and thus to a humidity of 40-60%, which is optimal for health.

Oxygen production approx. 1.5 g/h

Alwa - The algae wall produces approx. 1.5 g of oxygen per hour. At the same time the CO₂-Alwa contributes to the balance needed for office work.

Alfo in the office

The principle behind the algae water column is simple but effective. The algae absorb pollutants from the air and use them as nutrients for their growth. As they grow, they produce oxygen, which is then released back into the surrounding air. This process, known as photosynthesis, is similar to what plants do to produce oxygen, but algae are far more efficient at cleaning the air and absorbing other pollutants such as chemicals and particulate matter to boot.

In addition, the algae water column is not only functional, but also aesthetically pleasing. With its green, vibrant look, it adds a pleasant and calming atmosphere to any office. It can be used as a standalone element or as part of a green room concept to beautify the office and promote employee well-being.

The Algae Water Column is the perfect solution for office air purification. With its effective air purification function, sustainability and aesthetic value, it is an ideal choice for modern work environments that value healthy and pleasant indoor air. Try the Algae Water Column and experience the benefits of clean and refreshing air in your office!

Better air prevents signs of fatigue, allowing you to work in a more concentrated and efficient manner.

Also for home

The water column with algae tipping is not only beautiful to look at, but also easy to maintain. With little effort, you can make the algae grow healthy and magnificent, while the gentle splashing of the water creates a soothing atmosphere. The vibrant green of the algae adds a natural freshness to your living room and home, and acts as an eye-catcher in any room.

A water column with algae tipping is not only decorative and beneficial to health, but also an interesting topic of conversation for your guests. It is a unique element that will add a special touch to your home and show your love for nature.

Bring the beauty of nature into your home and enjoy this fascinating decorative element.


The water wall for home

Alfo is a wall of water almost 1 meter tall, which cleans its ambient air with the help of algae in a natural and biological way. 

Its compact shape makes it suitable for any room. Whether as a decorative element in the living room or to improve the air in the home office.

Easy exchange

Algae - convenient home delivery!

Like all organisms, algae are subject to a natural life cycle. Nach einigen Monaten können die Algen leichte Verfärbungen aufweisen und einen Teil ihrer Luftreinigungswirkung verlieren.

But do not worry! If you find that your algae is losing its effect, we offer you a simple solution. Simply order a new water column with fresh algae and have it conveniently delivered to your home.

Place your order online or contact us. Our algae are carefully cared for and are of high quality to ensure that they can develop their full effect.

However, it is important to note that the care and location of the algae will continue to have an impact on how long it retains its air-purifying effect. Regular maintenance, such as cleaning the water and controlling light and nutrient conditions, will have a positive effect on your algae. We also offer advice and guidance on how to best care for our algae to help you get the most out of your new green roommates.

Effect of a water wall

Water walls are considered to be very innovative decorative elements of our time. With their even and continuous flow of water, they bring movement and life to the room. Feelings of relaxation, well-being and fascination are triggered in the observer. 


Positive health effects

In rooms with dry air, human mucous membranes suffer. Eyes, mouth and nose become irritated. In addition, flu viruses multiply more quickly in dry air, which increases susceptibility to illness. A water wall has the property of supplying the room with the necessary humidity through its natural water evaporation. This humidification provides a strong reduction of these symptoms.


Advantages of the algae water wall

An algae wall combines the positive properties of a water wall with the air-purifying properties of microalgae. In closed rooms there is usually an increased concentration of fine dust, CO₂viruses and other chemicals that are hazardous to health. Unlike plants or mosses, microalgae are able to absorb these pollutants from the air, convert them and use them naturally for their own growth. This creates a perfect combination of innovative decorative element and unique biological air purifier.


indoor water wall

Water walls are suitable for indoor and outdoor use. Especially in the indoor area, the positive properties of the water walls come into their own. A water wall in the office will increase the humidity and counteract the dry office air. The results are a more pleasant working atmosphere and the prevention of tiredness and irritated eyes. If you decide to buy a water wall with integrated algae, the biological air purification of the micro algae will also come into play in addition to the humidifying aspect.

Rent a water wall

In addition to the direct purchase of an algae water wall, it is also possible to temporarily rent a water wall. This principle is particularly suitable for temporary events at which the attention of visitors is to be attracted by a unique eye-catcher. The assembly and dismantling is carried out by our trained specialist staff.


Office greening

Interior design is a big issue in many offices. The look should be modern and appealing. A feel-good atmosphere should be created to enable concentrated and efficient work. Often, the conventional way of planting plants or moss is resorted to. At first glance, this solution may seem plausible, but moss walls in particular turn out to be real dust catchers. Plants also lend a green flicker to the room, but have only a very small effect on reducing the concentration of air pollutants. Thus, symptoms of fatigue and concentration difficulties are hardly counteracted. 


Algae instead of office plants

Unlike plants, algae do not need soil and feel very comfortable even in low light conditions. While office plants draw their nutrients from the soil, microalgae absorb them from the air. They convert the used air into fresh oxygen and release it into their environment.

Unlike office plants, algae not only take up CO₂ but also bind fine dust and other chemicals that are hazardous to health. The improved indoor air counteracts fatigue and increases concentration and motivation at work. In addition to these health-promoting properties, the look of the water walls made of algae is unique worldwide and will attract attention. The low-maintenance system with integrated microalgae can therefore be considered the best alternative for indoor plants.
