Moss air purifier

Sensors & maintenance
Moss has the natural ability to bind and metabolize fine dust. In addition, mosses cool the ambient air by evaporating water on their enormously large leaf surface. We combine these natural abilities with state-of-the-art sensor technology and smart ventilation & irrigation technology. The combination of these technologies not only ensures the survival of mosses outside their natural habitat, but additionally optimizes their cooling and filtering effect on the environment. The built-in sensor technology additionally generates enormous amounts of real-time data, which is made visible by a specially developed online dashboard and can be used to prove the air quality as well as the environmental performance of the bio-filter.

CITYTREE
Nature Knows Best
The CityTree is a combination of street furniture and biofilter – a bench at the bottom, a moss-covered surface at the top, and complex technology with an IoT interface inside. This opens up further application possibilities, e.g. in the areas of smart city, (e-mobility) infrastructure and communication.

CITYBREEZE
Green meets Screen
The CityBreeze combines natural air filtration with digital presentation technology. On one side is a green, vitalizing moss wall with active filter technology and on the other a 75″ LCD screen. This makes the CityBreeze the first out-of-home totem that cools the ambient air instead of heating it up.

Our products can be extended by various add-ons and thus act as a central communication tool and neighborhood meeting point for your location.
Aircare
Our Software
The CityTree houses a unique IoT technology that contains a multitude of measuring points. The built-in sensor technology generates enormous amounts of real-time data, which is made visible by a specially developed dashboard. Our AirCare and AirCare+ software packages differ in the depth and breadth of data they provide. Depending on the variant, you will receive data on plant sensing, filtered air volume, plant condition, meteorological environmental factors and local air quality. Overall, AirCare+ offers you the possibility to show the positive effects of the CityTree on its environment through additional sensors.

Product experience
The phase of preparation, the opening ceremony and the time when the moss filters produce healthy & fresh air is characterized by WOW moments. We help you to highlight these moments in an attention-grabbing way. Let us tell your sustainability story together.
Advance communication

“We create involvement and inform residents and visitors.”
Opening ceremony

“We’re taking the media through the product launch with an opening event.”
Follow-up communication

“We’re keeping the excitement high by offering reports and other events & workshops.”
DATA ANALYSIS
Each project is accompanied by our data analysis and sensor specialists. Depending on the offer, you will regularly receive detailed reports on the achieved improvement of air quality and other factors of the site analysis. Based on this data, you can visualize your positive contribution to the urban climate and communicate it.
Our analyses also enable us to adapt the temporal filter performance individually to the needs on site and thus to filter particularly actively in times of high air pollution.
