Exhaust air goes outdoor
The exhaust air from a floor vacuum cleaner creates dust in the room. Particulate matter accumulates visibly in the living space after hours, which results in frequent dusting. This is not the case with a crossvac central vacuum cleaner with HEPA filter, because it hangs in the basement or in the garage and blows out the exhaust air away from all living rooms - mostly outdoors.
Clean indoor air for a longer time
Each person consumes at least 15,000 litres of air per day. The quality of the air you breathe in has a considerable effect on your health. Ironically, conventional floor vacuum cleaners in particular cause air turbulence due to the engine exhaust air in the living area.
