About a month I was on here and clicked on a thread where a guy was going to modify a competitors reusable bag and was asking if anyone has tried that route. a response was a link to a UK tool store that carried their own version of a longer lasting bag than the disposable but not quite the caliber of Festool's long-life bags. The next item on the webpage was: Festool Longlife filter bag -FIS-CTL MINI Festool part # 499703!!! I didn't know they existed! I never would have thought Festool would not offer that, I just assumed they had decided not to produce them and started at CT 26. i bought a CT26 thinking that was the smallest vac with the Long-life filter bag option. I even bought an additional CT 26 bag and was going to modify it into two CT Mini bags! (I have two Mini's I stack them to get dust collection for my Kapex and my Table Saw rather than purchase then have to modify an automatic blast gate setup. if I figure out how to post pics, I'll upload that fancy shmancy modification) A gal I went to school with works for an Airline and lives in the UK. I purchased and shipped them to her house. she is en route with them as I write this.
