Atrea

Model compatibility

This category includes filter sets compatible with all major Atrea MVHR ventilation units, including:

• Duplex Slim series
• Duplex Pro / Pro-V series
• Duplex EC5 / ECV5 series
• Duplex Easy / Easy2 series

To ensure the right fit, it’s important to know the exact model of your ventilation unit, as different models require different filters. You’ll find helpful tips on identifying your device in the FAQ section.

Filter types and what they protect against

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

• G4 filters (ISO Coarse 75%) on the extract and/or supply side: ideal for capturing larger particles like soil particles, large pollen grains, plant debris, insect wings, sawdust, sand and textile lint.
• F7 filters (ISO ePM1 55% or ePM10 55%) on the extract and/or 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 Atrea filters are manufactured by a respected family‑owned company based in the Czech Republic. They coordinate production through branches and authorised partners across Europe, where they maintain strict oversight of product quality. 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.
