Festool FIS-CTH 48/3 Safety Filter Bags for CTH 48
At a Glance: Genuine Festool double-layer safety filter bags developed specifically for the CTH 48 Dust Class H mobile dust extractor. Each bag combines a highly flexible fleece filter bag with an additional PE outer layer and secure end-cap closure for controlled handling and disposal of hazardous dust. Suitable for applications involving carcinogenic and pathogenic dust, mould, mineral fibre dust, hazardous wood preservatives and specified heavy-metal compounds. Supplied in a pack of 3.
The Festool FIS-CTH 48/3 is the dedicated safety filter bag system for the Festool CTH 48 Dust Class H mobile dust extractor. Designed for professional environments where particularly hazardous dust must be contained reliably, each safety bag uses a double-layer construction consisting of a highly flexible fleece filter bag surrounded by an additional layer of PE material. This arrangement provides an extra level of containment and supports safe handling of collected hazardous material. Once the bag has been removed from the extractor, an integrated end cap provides a secure closure to help minimise the release of collected dust during disposal. Festool specifies the FIS-CTH 48/3 for applications involving carcinogenic and pathogenic dusts, including asbestos, mould and mineral fibre dust, as well as hazardous wood-preservative treatments and substances such as cadmium, nickel and zinc chromate. The bags meet the requirements associated with Dust Class H applications and are FSC™ certified. Three genuine Festool safety filter bags are supplied per pack.
The FIS-CTH 48/3 differs from an ordinary filter bag by combining a flexible fleece inner bag with a second protective layer made from PE material. This double-layer construction is designed specifically for the hazardous-dust applications handled by the CTH 48 and provides additional containment during use, removal and disposal.

Extra Information
- What does FIS mean? FIS identifies the Festool filter-bag product family.
- What does CTH 48 mean? CTH 48 identifies the compatible Festool 48-litre-class mobile dust extractor configured for Dust Class H applications.
- What does /3 mean? The package contains three safety filter bags.
- Why is the bag double-layered? The inner flexible fleece bag collects the dust while the additional PE layer provides a second containment barrier for hazardous material.
- How is the bag closed? Festool provides a secure end-cap closure so the bag can be sealed when it is removed for disposal.
- What is Dust Class H? Dust Class H is the highest of the commonly referenced L, M and H dust classes for mobile dust extraction and is intended for particularly hazardous dust, including carcinogenic and pathogenic materials.
- Does the filter bag alone make an extractor Dust Class H? No. Dust classification applies to the complete approved extraction system. The FIS-CTH 48/3 is one component designed specifically for the Festool CTH 48 and must be used together with the correct extractor, filters and operating procedures.
- Can it be used for asbestos? Festool lists asbestos among the intended hazardous-dust applications of the CTH system. However, asbestos work is highly regulated and may require licensed contractors, specialised procedures, approved PPE, controlled work areas and legally prescribed waste disposal.
- What does FSC™ certified mean here? Festool states that the fibre material used for its certified filter bags originates from responsible forest management and other controlled sources, with the relevant supply chain FSC certified.
Dust Class H is intended for highly hazardous dust with very low occupational exposure limits, including carcinogenic and pathogenic materials. Festool specifies a filtration efficiency greater than 99.995% for the complete Dust Class H filter system. The FIS-CTH 48/3 safety bag forms part of that system, but the classification applies to the correctly configured complete extractor rather than to the bag on its own.
Collecting hazardous dust is only one part of safe extraction. The dust must remain contained when the extractor is opened and the bag is removed. The FIS-CTH 48/3 therefore uses a double-layer arrangement and secure closure so the collected material can remain enclosed during handling and disposal when the prescribed process is followed.
A standard filter bag is designed primarily to collect ordinary workshop dust and protect the extractor's filtration system. The FIS-CTH 48/3 is purpose-built for hazardous Dust Class H work and adds a second PE containment layer and secure closure. It should therefore be regarded as a specialised safety component rather than simply a higher-capacity replacement bag.
