SEBO’s FILTRATION SYSTEM:
Step One. Bags are Better! – On all models, top-fill, three and four-layer bags are an integral part of SEBO’s filtration system because they hold virtually all dirt captured by the vacuum, which improves the effectiveness and useful life of the microfilters. They also ensure continuously strong suction because dirt enters from the top, deposits at the bottom, accumulates upward, and air exits through the sides, which allows unimpeded airflow as they fill to capacity. And they can be sealed when full, so no dust can escape into the air during bag removal and disposal.
In contrast, without bags to hold nearly all the captured dirt, the microfilters on bagless vacuums quickly clog from excessive dirt build-up and must be replaced often, or a loss of suction and cleaning effectiveness will occur. In addition, dust and other allergens become airborne when emptying bagless dirt containers. Lastly, bagless vacuum microfilters are expensive, usually costing more than a multi-year supply of SEBO filter bags.
Step Two. Pre-motor Filters – Pre-motor filters clean suction air after it passes through the filter bag, but before it passes over the vacuum motor. Cooling the motor with clean air is important because this increases useful life expectancy.
Step Three. S-class Exhaust Microfilters – S-class Exhaust Microfilters (S =“Schwebstoff” = airborne particles) are made from electrostatically charged micro-fiber material, which attracts and captures dust particles from the airflow of the vacuum after it passes over the motor to cool it. This means that exhaust air is cleaned to the highest level. The S-class Standard requires filters to absorb greater than 99.9% of particles down to 0.3 microns in diameter. For comparison, 100 microns is the diameter of a human hair. Their advantages are a relatively open texture that allows smoother airflow for better suction performance, a longer life expectancy, and they cost less than HEPA filters.
STANDARD FEATURES OF ALL SEBO VACUUMS:
Designed and Manufactured in Germany – Legendary quality, reliability and performance make SEBO vacuums the choice of cleaning professionals throughout the world.
Excellent for Users With Allergies or Asthma – The British Allergy Foundation recommends SEBO filters.
Tightly Sealed Vacuums Ensure Effective Filtration – Dirty air, which flows through a vacuum, can only be filtered completely if it does not escape into the room through seams or seals in the machine. This is why all
SEBO vacuums have tight seals throughout.
Many vacuum companies with high-filtration claims are actually quoting specifications made by the manufacturer of the filter material, as measured in the laboratory, not the filtration effectiveness of the vacuum itself while operating. Whether or not dirty air can escape through leaks in the body of the machine is not considered. The filtration effec- tiveness of SEBO vacuums is tested while they operate.
Save Money! SEBO Vacuums Last for Years and Extend Carpet Life! – If properly maintained, SEBO vacuums save
ordinary residential users hundreds of dollars by providing excellent performance for ten to fifteen years or more, and their deep-cleaning power-brush technology extends the life of carpets. Typical vacuums perform poorly, even when new, and usually do not last beyond two years. So six or seven “disposable vacuums” must be purchased during the average life expectancy of just one SEBO machine.
Five-year Warranty Coverage – All SEBO models include a five-year warranty on the motor and all non-wear parts and a five- year warranty on labor charges.
SEBO Microfilters Ensure Continuously 
Strong Suction Performance – They are also long lasting,
inexpensive and easy to change in seconds.
Changing Bags is Easy and Clean – SEBO filter bags can be changed in just a few seconds, and a cap keeps dust sealed inside during removal and disposal.
Effective Pet Hair Removal – All SEBO vacuums easily remove pet hair!
