PurCity's patent pending solution (GapS), consists of novel industrial facade panels that are great substitutes for exterior facades/flat surfaces of any New/Existing buildings. Leveraging from chimney effect/natural ventilation, polluted air is naturally sucked into the panels and forced to pass through a harmless chemical process that traps CO2, particulate matter PM2.5/10 & inorganic gases. Then clean air will be delivered into the building through the Air conditioning (HVAC) system. GapS utilizes smart monitoring and control solutions, to optimize its performance. The collected polluted liquid is continuously recycled, generating valuable byproducts like Hydrogen, pure O2 and CO2 that are sellable in the market, benefiting sectors such as food, cement and agriculture.

Airplant ApS develops innovative and effective solutions to improve the air quality in office settings. Airplant increases the effect of nature's ability to purify and humidify air by combining plants and technology. 20-40 % of office workers experience dry indoor air. The feeling is triggered by dry air or chemicals which cause general discomfort. As you may know, plants reduce chemicals and humidify air. The Airplant system boosts the plant's natural way of working, and an airflow expands the treated area so that one single plant has the effect of 10 plants, corresponding to or better than comparable machines. Ventilation systems switch indoor air with fresh air. But fresh outdoor air is dry during the entire flu season so the Airplant system will humidify the fresh air and also reduce the amount of harmful chemicals. Sustainability is at the heart of our product, our production and everything we do in our company, guided by the UN Sustainable Development Goals. We strive to make the world a better place to live: Airplant's mission is to support health at the office. We love to work with ideas that solve important problems and to bring the products to life, to do product development, prototyping and the initial low volume production. We do our own research and development - standing on the shoulders of NASA, among others. Do you see the potential in a partnership, an investment or would you like to work at Airplant? Please do not hesitate to contact us. Next step: Introduce the Airplant product for offices to the market this fall. Attract commercial competencies to the Airplant company. Frequently given answers: We have a PCT patent pending for the Airplant system. We have a strong partner for sales and service who will bring our product to the Danish market. We are always interested in exploring new ways to improve indoor climate in cooperation with others. The Airplant system yields plenty of opportunity for interaction with other products, e.g. to support solutions for smart buildings and smart cities.
