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.
HEPA Pre-motor Microfilters ("High Efficiency Particulate Air") remove a minimum of 99.97% of all airborne particulate matter down to 0.3 microns in diameter. Because these filters use small grid-like structures to capture dust particles, dirt build-up clogs the airflow pathway sooner than what is expected from S-class microfilters. However, SEBO’s HEPA microfilters are sold along with four-layer "Ultra-bags," which provide highly effective filtration before the airflow goes through the HEPA microfilter, greatly increasing life expectancy and reducing the potential of diminished air flow.
This amazing powder cleans carpets or upholstery to like new condition and removes even the most stubborn stains! It is made of polyurethane granules moistened with a cleaner and is environmentally friendly and safe to use. And, unlike other cleaning powders, no “pre-spray” is needed. (Tightly seal partially used packages after opening to maintain moisture.)
When the powder is worked into the carpet fibers, the moistened sponge-like granules lift soil and stains out. Within 30 to 60 minutes, the powder is dry and is removed by vacuuming, leaving the carpet or upholstery clean, dry and ready for use. And the GAF allergy research center in Germany found that six months after a single cleaning with duo-P, seven out of ten carpets remained free of dust mite allergens.
