Filter types and what they protect against

Our replacement filter sets for Paul units are designed to ensure optimal air quality and system performance through a combination of filters with different filtration roles. Available filter options:

• G4 filters (ISO Coarse 70%) on the extract and supply side: ideal for capturing larger particles like soil particles, large pollen grains, plant debris, insect wings, sawdust, sand and textile lint.
• M5 filters (ISO Coarse 75% or ePM10 55%) on the extract and supply side: ideal for capturing larger particles like pollen, mould spores, pet dander, and house dust.
• F7 filters (ISO ePM1 55%, 60% or 70%) on the supply side: high-efficiency filters that capture very fine particles, including 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

The original filters are manufactured by Paul, a part of the Zehnder Group at Zehnder’s production facilities located in the Netherlands, France, and Switzerland. Our carefully developed house brand filters are also made in the European Union by certified manufacturers. Both are produced with high-quality materials, under strict ISO 16890 standards to ensure high filtration performance and reliability.
