For over 75 years, our research, development and quality control laboratories have tested methods to effectively pick up and, most importantly, retain dust and other indoor air pollutants.
After collecting volumes of data, engineers and designers continue to reach the firm conclusion that Miele's system is the most effective and hygienic method of removing particulate matter from the home.
Our exclusive combination of a Sealed SystemTM using the very best raw materials, electrostatically charged IntensiveClean PlusTM dust/filter bag and a selection of high-quality filter cartridges, including the first certified HEPA filter, provide the essential formula for this success.
As a matter of fact, the new S4 Galaxy series has been awarded certification by the DMT Air Quality Testing Institute, an independent institute that monitors air hygiene. The S4 joins other Miele vacuums — which were the world's first to receive this certificate — with a top rating of “excellent air quality”.1
This certification refers to Miele's HEPA filter and the vacuum cleaner working together as a Sealed SystemTM to provide maximum protection for indoor air quality.
Please exercise caution when evaluating other vacuum filtration systems, since there are many gimmicks that do not work as effectively or scientifically.
Since this is an area where poor results can be devastating to young or elderly lungs, or to anyone who suffers from allergies or asthma, you may want to visit a local authorized Miele dealer to discuss the importance of the indoor air quality in your home and how a Miele vacuum cleaner can improve it.
