How to Use
- Confirm compatibility with a Dromex twin‑cartridge respirator.
- Inspect the pre‑filter for damage or contamination before use.
- Fit the pre‑filter onto the compatible cartridge as per respirator instructions.
- Ensure the respirator is correctly sealed on the face.
- Monitor breathing resistance and replace if airflow is restricted or contamination is detected.
⚠️ Do not use in oxygen‑deficient environments or unknown/IDLH atmospheres; these filters do not supply oxygen and must only be used with compatible respirator systems.

FAQs
- Can this pre‑filter be used alone? No, it must always be used with a compatible Dromex gas or combined filter cartridge.
- What does P3 filtration mean? P3 is the highest particulate protection class under EN143, providing filtration efficiency up to 99.95% against airborne particles.
- Is it compatible with all respirators? No, it is only designed for Dromex twin‑cartridge (EN302) respirators.
- When should it be replaced? Replace when breathing resistance increases or contamination is detected.
- Can it filter gases or vapours? No, it filters particulates only and must be paired with a suitable gas filter for chemical protection.
