Vacuum cleaners are designed to remove dust, dirt and debris from your carpeting and furniture.
In order to produce a vacuum cleaner that actually performs its primary function successfully, it must first have adequate airflow to gather dirt and debris. Unfortunately, not all vacuum cleaners do this. The second part of the equation is filtration. Most vacuum cleaners lack the design and proper filtration system required to contain microscopic particles that have escaped through the dustbag as well as any particles that may be generated by the motor. This post motor filter design, in conjunction with rubber sealing throughout the system, is crucial to maintaining clean air.
Every Miele vacuum cleaner, including our upright units, come standard with a double layer dustbag, a pre-motor filter, and an advanced exhaust filter configuration. Over the past 75 years, our engineering and production laboratories have tested hundreds of methods to improve dust pickup and retention ratios. Miele's firm conclusion is that using a dustbag is the most effective and hygienic method of removing dust from the home while maintaining superior indoor air quality.
Miele canister and mini-upright vacuums offer three exhaust filter options to capture the tiny particles that have escaped through the dustbag as well as any particles that may be generated by the operation of the motor. These post motor filter designs, working in conjunction with rubber seal throughout the system, are crucial to maintaining clean air.
First, and most commonly included in Miele vacuums, is the electrostatically charged Super Air Clean filter.
This filter is designed for normal household use, where allergies and odors are not an overwhelming concern. The Super Air Clean filter is made of a multiple layer, random-spun, electrostatic charged material that retains 99.9% of all particles 0.5 microns and larger and 94% of particles down to 0.3 microns in size. This filter lasts as long as five dustbags and is included with each box of bags.
Next is the Active Air Clean filter.
This combines the Super Air Clean Filter with active charcoal pellets, which absorb odors - especially useful if you have pets in your household. The Active Air Clean filter achieves the same superb filtration results as the Super Air Clean filter and has an operating life of approximately 12 months or 50 hours of vacuuming.
Finally, there is the Active HEPA filter.
Vacuuming can be a nightmare for people who suffer from dust allergies, as tiny particles of dust, such as dust mite feces and pollen can be disturbed and remain airborne for hours, exacerbating conditions such as bronchial asthma and rhinitis.
With an Active HEPA filter installed within the Sealed System casing of select series of Miele vacuums, real allergy-relief can be a reality. Our certified HEPA filter traps 99.9% of particles down to 0.3 micron in size - that is 1/200 the width of a strand of human hair.
A H.E.P.A. filter, even a certified one like ours, is useless if the vacuum cleaner leaks air prior to passing through the filter like some other "HEPA-like" or "HEPA-type" vacuum cleaners do.
- When using a Miele canister or mini-upright with HEPA, you are guaranteed to capture, retain and filter virtually all particles.
- Our engineers have crafted an air-tight dust chamber, with rubber gaskets, to ensure that the air passes through the final exhaust filter and is not leaked out.
- Miele's advancements in this area have been so remarkable that the new S5 and S4, and the S500 and S600 series are the first ever HEPA certified vacuum cleaners in the world.*
