Festool 498411 CT MIDI Self Cleaning Filter Bags, 5-Pack an innovative solution for maintaining optimal suction power in your CT MIDI dust extractor. These self-cleaning filter bags are designed to prevent the common issue of dust caking on the inner lining, which can significantly reduce extraction efficiency and strain the motor. Made from a unique pliable fleece material, these bags avoid the rigidity of traditional paper bags, ensuring full suction performance until the bag is nearly full. They act as a pre-filter, capturing dust particles as small as 5 microns—comparable to the size of a red blood cell—helping to extend the life of your main HEPA filter and reduce costs. Disposal is quick and mess- thanks to an integrated closure that prevents spills, and the tear-resistant material prevents bag blowouts. This 5-pack of durable, self-cleaning fleece bags is specifically designed to fit Festool CT MIDI dust extractors, providing reliable and efficient dust extraction every time. Model Number: 498411
