Ventilation improvements in Malmö, VFB We at Ventilationsförbättringar (VFB) take special care of the indoor environment and are specialists in ventilation, heat pumps and comfort cooling. Ventilation improvements in Malmö AB (VFB) was established in 1979 as a service company for ventilation systems and we are today 29 employees, of which 3 are co-owners. Our environment is incredibly important. Every year, environmental work with air and water purification costs many billions of kronor. Sweden has the cleanest outdoor environments in the world, partly for natural reasons depending on our geographical location but also depending on the environmental measures taken. However, we stay outdoors only a small part of the day, the rest of the time we spend indoors. Despite this, significantly less funds are set aside to improve the indoor environment than the outdoor environment. Our organization number is 556256-3279 and we have an F-tax certificate.
