The iQ Power Tools Cyclonic Dust Extractor with Hepa Filtration (IQ426HEPA CSA) is equipped with a four stage filtration system, two of which being the primary cyclone followed by the six secondary cyclones. Utilizing this two stage cyclonic filtration process, the cyclones pull and capture large and medium sized particles out of the airstream, keeping them from reaching the third and fourth stages (Durabond Filter and HEPA Filter).

Having cyclones filtering dust and debris at the first two stages not only protects your filter from clogging up and keeps your suction strong, it also gives the IQ426HEPACSA the versatility to pick up different types of debris of various sizes, without you ever worrying about clogging. What makes this Vacuum Dust Collection System (VDCS) truly unique is the two stages of cyclonic filtration, as this means that less than 1% of the dust ever reaches the filter. With a clean filter, vacuum suction stays strong and operating at its optimum performance level. The cyclonic filtration process and a clean filter is what gives the IQ426HEPACSA its powerful 190 CFM of suction power, making it the most efficient dust extractor in its class.
