The P2-02 filter holds a P2 classification in accordance with EN143:2021.

EN143:2021 has three classifications, which describe the minimum filtration efficiencies required against both solid and oil-based particulates (tested via NaCl salt and paraffin oil challenges, respectively):

• P1 is >80%
• P2 is >94%
• P3 is >99.95%

The P2-02 performs well above the 94% threshold; it tests ≥99% filtration efficiency against solid particulate. The P2-02 also demonstrates >97% efficiency for oil-based particulates.

The design of the TR2 and filter were improved in order to meet the requirements for CE standards in three specific test areas. These changes represent the primary differences between the Gen1 TR2 and Filter and the CE-Certified TR2 (with P2-02 filter):

• New Exhalation Valve
• New Small Head Harness
• New and Improved Filter

Useful life of any filter depends heavily on environmental and usage conditions. For example, filters used in less contaminated environments may offer longer service life than those used in heavily contaminated environments.

Excessive breathing resistance when inhaling indicates that the cartridge has served its useful life. Leave the contaminated area and replace the filter cartridge. Cartridges should also be replaced when physically damaged or visibly soiled.

The CE-Certified P2-02 filter cartridge is compatible with both the CE-Certified TR2 as well as the Gen1 TR2.

The body of the CE-Certified TR2 is labelled with a sticker which displays the CE Mark.

The P2-02 filter cartridge housing is also labelled with a sticker which displays the CE Mark.
