Filter types and what they protect against

Our replacement filter sets for Wolf units are designed to ensure optimal air quality and system performance by combining two filters with different filtration roles. Available filter options:

• G4 filters (ISO Coarse 60%) and G3 (ISO Coarse 50%) on the extract or supply side: ideal for capturing larger particles like soil particles, large pollen grains, plant debris, insect wings, sawdust, sand and textile lint.
• M6 (ISO ePM10 50%) and F7 filters (ePM1 55%) on the supply side: high-efficiency filters that capture very fine particles, including pollen, pet dander, bacteria, smog, tobacco smoke particles, combustion dust, spores, and wildfire smoke particles.

Usage and maintenance

To keep your MVHR system running efficiently and your indoor air clean, we recommend replacing the filters every 3–6 months. However, this depends on your environment, if you have pets, or nearby construction.

To make the process easy, we provide step-by-step replacement instructions for each filter model. You can find them under the “How to change” tab on every product page.

Manufacturing quality you can trust

Our carefully developed house brand filters are made in the European Union by certified manufacturers. They are produced with high-quality materials, under strict ISO 16890 standards to ensure high filtration performance and reliability.
