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.
