Our selection includes high-performance filter sets combining G4 (ISO Coarse 75%) and F7 (ISO ePM1 55% or ePM10 55%) filters, designed to protect your system and improve indoor air quality. Whether you’re looking for original Atrea filters or affordable house brand alternatives, all our options are quality-tested and fully compatible with Atrea MVHR units. 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.

We’ve gathered answers to the most common questions about our products and services. If you can’t find an answer here, please contact us directly.
Which Atrea units are covered by your filter range?
We stock replacement filter sets for the Atrea Duplex range, the brand's most widely installed residential and light-commercial MVHR series across Central and Eastern Europe. If your unit carries a Duplex nameplate but you're unsure of the exact variant, measuring the filter's length, width and height is the most reliable way to match it in our catalogue.
What happens if the Atrea filter I order doesn’t fit my Duplex unit?
If a filter you've ordered turns out not to match your Duplex variant, we accept returns or exchanges as long as the filter is unused and in its original packaging. Sending us your exact Duplex model code or the measured filter dimensions upfront is the easiest way to avoid a mismatch in the first place.
Can I fit an activated carbon filter to my Atrea Duplex unit for extra odour and VOC control?
Some Atrea Duplex variants support an additional activated carbon filter layer on the supply side, which helps absorb traffic fumes, cooking odours and general VOCs before they enter the home. It's typically fitted alongside — not instead of — the standard M5/F7 filtration, so check your unit's housing depth before ordering.
Can I upgrade my Atrea filter class for better allergen protection?
Many Atrea Duplex units accept both standard M5 and higher-grade F7/ePM1 filters in the same housing without any modification. If you or a family member suffers from pollen or dust allergies, upgrading the supply-side filter to F7 is one of the simplest performance upgrades available for these units.
How often should Duplex filter cartridges be replaced?
Atrea's guidance for Duplex filters covers three checkpoints:
- Check filters every 3 months
- Replace them at least twice a year, even if they still look clean
- Watch for the RD5/RD6 controller's on-screen maintenance reminder, which triggers once pressure drop across the filter rises
Following that on-screen prompt rather than a fixed calendar date gives the most accurate result for your specific air quality conditions.
