S-Class Filtration

What is the S-Class Filtration?

Every SEBO upright and canister vacuum cleaner is equipped with the exclusive S-Class, hospital-grade filtration technology

In case you’re curious, the “S” represents the German word “Schwebstoff”, which directly translates to the term “airborne particles”. 

The S-Class Filtration is a European standard, comparable to the popular North American term “HEPA”. However, unlike the HEPA standard where only the filter is expected to absorb 99.97% of particles down to 0.3 microns, the S-Class Filtration standard can only be obtained by having met all three of the following criteria:

1) A three stage, hospital-grade filtration that filters 99.9% of particles down to 0.3 microns before exiting all SEBO vacuums

2) An electrostatic filter that uses statically charged microfibers

3) A completely sealed vacuum cleaner that does not leak air from any side

This three step filter process absorbs greater than 99.97% of particles
down to 0.3 Microns in diameter. 

It will remove 100% of particles of 1 micron and above. Dust mite feces are
approx. 10 microns.


Three Stage Filtration

Step One – A three-layer Ultra Bag
Step Two – A pre-motor micro-filter
Step Three – An S-Class, or optional HEPA, exhaust micro-filter

Electrostatic Filtration

Electrostatic filtration uses statically charged micro-fibers that attract dust particles from the air stream, which then bond onto the fibers. This enables the filter material to have a relatively open texture allowing for smoother air flow. This also improves suction performance while maintaining a highly effective filtration.

 

Tightly Sealed Vacuums

Dirty air that flows through a vacuum can only be filtered completely if it does not escape into the room through seams or seals in the machine. As a result, every SEBO vacuum cleaner is 100% sealed from seam to seam.

Did you know?

Most vacuum cleaner manufacturers make HEPA, or other high-filtration, claims based on laboratory data acquired specifically for the filter material being used and nothing else. They do not take into consideration the filtration effectiveness of the entire vacuum when being operated. This means that there is a potential for dirty, unfiltered air to leak through the seams and seals of the vacuum while it operates, resulting in a lower filtration performance overall. 

However, as mentioned above, the only way a vacuum can reach the S-Class filtration status is to have an entirely sealed vacuum. This is why the filtration effectiveness of each SEBO vacuum is tested while they operate to ensure every SEBO vacuum continues to meet the S-Class Filtration standard, year after year.


British Allergy Foundation Seal of Approval

British Allergy Foundation tests found that the filtration system removes 100% of the dust mite allergen and the SEBO bag system made emptying ultra hygienic.

No Escape For Dust

With the SEBO system, once dust has been picked up, you never have to face it again.
