Please note: To effectively be a complete sealed system you must be using a hepa filter.
For over 75 years, Miele's 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, their 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.
Miele's exclusive combination of a Sealed System using the very best raw materials, electrostatically charged IntensiveClean Plusdust/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 and S5 Galaxy series has been awarded certification by the DMT Air Quality Testing Institute, an independent institute that monitors air hygiene. The S4 and S5 join other Miele vacuums — which were the world's first to receive this certificate — with a top rating of “excellent air quality” by conforming to the stringent European standard for filtration (EN1822).
This certification refers to Miele's HEPA filter and the vacuum cleaner working together as a Sealed System 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. |
