Festool long-life filter bag is a sturdy, reusable filter bag designed for CT MINI and CT MIDI dust extractors from 2019 onwards, so it handles ongoing clean-up on the same units you already rely on in the shop. The bag is described as long-life and reusable, so it is built to stay in service rather than being treated as a single-use consumable. It is intended for collecting coarse chips and debris, giving you a way to capture larger waste directly at the source during sanding, routing, or general cleanup. The design focuses on safe disposal of dry, non-hazardous dust, so dust stays contained from collection through disposal. A high-strength, 3-layer polyester fleece construction supports a long service life, so the bag resists tearing while being emptied and reused. The manufacturer does not recommend this bag for fine dust, keeping its use focused on the coarse material it is designed to handle.
The description ties this longlife filter bag to CT MINI and CT MIDI extractors from 2019 onwards, so selection centers on those model ranges in that year and later. A long-life, reusable design means the same bag handles multiple fill-and-empty cycles, so workflow focuses on emptying the bag rather than swapping disposables. Its purpose-built role for coarse chips and debris means it works where larger particles are created, aligning the extractor setup with heavier cut waste. The high strength, 3-layer polyester fleece construction supports the repeated flexing and abrasion from chips and dust, so the bag can stay in service over an extended period. Because it is not recommended for fine dust, it fits best into stations or tasks where coarse debris is the main waste stream.
The longlife filter bag is described as ideal for collecting coarse chips and debris, so it performs best in tasks such as routing, planing, or heavier sanding that create larger particles in the CT MINI or CT MIDI stream. By targeting coarse debris, the bag keeps bulk material contained inside the extractor instead of spreading around the work area. Safe disposal of dry, non-hazardous dust means collected material can be carried away in the bag without releasing dust during normal handling, so sweep-up time stays focused at the extractor. The bag is not recommended for fine dust, so it fits into setups where the majority of waste is shavings and chips instead of very fine particulate. Matching it to coarse material in this way keeps its performance aligned with the role Festool assigns to this part.
The designation as a long-life, reusable bag signals that Festool designed this part to remain in service rather than be discarded after a single use, so shops can rely on one bag through many emptying cycles. The stated ability to last up to 500 uses shows a focus on extended service life, so the same bag supports long-term extractor operation before a replacement is needed. High strength, 3-layer polyester fleece construction underpins that long service life by resisting tears and wear as coarse chips and dust move across the material. This construction also supports the containment of dry, non-hazardous dust during transport, so dust stays inside while the bag is carried out of the work area. Together, the reuse capability and material strength keep the extractor setup stable over many cycles of collection and disposal.
The longlife filter bag is intended for Festool CT MINI and CT MIDI dust extractors from 2019 onwards, so it matches those models in that production range.
