The Festool 201875 CT 26/36/48 Filter Housing is a replacement filter housing for select Festool dust extractors. This is a filter housing designed for restoring or replacing the filter compartment component on compatible CT extractors. Model Number 201875. If you are servicing a CT 26, CT 36, or CT 48 and need the correct housing piece instead of a generic substitute, this is the part you look at first.

What matters here is fit. On extractor parts, close enough usually is not good enough. A filter housing needs to match the machine platform it was built for so the filter area goes back together the way Festool intended. That helps avoid wasted time ordering a part that physically does not line up with the extractor body or the filter assembly it is meant to support.

This part is aimed at owners of compatible Festool CT dust extractors who are maintaining an existing machine rather than replacing the whole unit. If the housing on your extractor has been cracked, worn, or otherwise compromised, replacing just that component is the practical move. It keeps the repair focused and can help extend the working life of the extractor you already own.

The direct compatibility callout in the product name is the big buying detail: CT 26, CT 36, and CT 48. That makes this a straightforward service part for shops, finish carpenters, remodelers, installers, and other users already invested in the Festool dust extraction platform. Instead of sorting through broad fit claims, you have a defined match to specific extractor models.

As with most replacement parts, this is best for buyers who already know the component they need. If your machine is one of the listed CT models and the filter housing is the failed or missing piece, the Festool 201875 CT 26/36/48 Filter Housing is the clean fix. If you are trying to solve a broader performance issue, confirm the housing is the actual part at fault before ordering.
