8 hours in a poorly ventilated area or perhaps even a polluted environment stemming from dirty ductwork can present a number of symptoms like headaches. Which can be eliminated by having the ductwork cleaned. As part of a survey and inspection INTELblast can also assist in pointing out other parts of the building (e.a carpets, wall paper etc) that could be the course or could contribute to a poor indoor air quality.

Offices are according to the EN 15780:2011 standard classified as “Medium” with a recommendation to inspect the ductwork every 48 months and that the acceptable level for cleanliness is 3,0 gram of dust per square meter in the supply ductwork.
