Double vacuum cleaner. Why vacuum the floor if the air is contaminated after that? This is precisely the question that arises from the fact that your vacuum cleaner collects coarse dust and dirt, but releases smaller particles back into the ambient air. Especially for small children and allergy sufferers dust and the allergenic substances contained in the exhaust air present a risk. ScanPart HEPA filter gets you unloaded and clean air in your home. HEPA is the abbreviation for High Efficiency Particulate Air and is a specific type of air filter that filters between at least 85% and a maximum of 99.99% of all dust particles, depending on the filter type, with a size of 0.3 micrometers.The ScanPart HEPA filters keep (with the H12 filter class) 99.5% of all particles larger than 0.0003 mm away from the exhaust air of your vacuum cleaner. We are happy to replace your ScanPart HEPA filter at least once a year.This text is machine translated.
