Hamster Cleaning provides professional cleaning and inspection services of air ducts. Every day, projects are carried out in a range of sectors and (office) environments, such as public buildings, SMEs and multinationals, healthcare institutions, sports centres, university hospitals, laboratories and food service companies. The difference we want to make as our contribution to the climate challenge is to focus on ventilation hygiene. “Clean from the inside” and properly maintained systems reduce the CO2 footprint of buildings. Less energy consumption means a better outdoor air quality. Clean ventilation systems also ensure a safe and clean work and living environment; contributing to the indoor air quality. By cleaning ventilation systems from the inside, we contribute to the environmental quality, both indoors and outdoors. For a better world, inside out.
