1-15 of 35Discover our range of replacement filters for your Vallox ventilation unit, all made in the EU! Our selection includes high-performance filter sets combining G4 (ISO Coarse 75%) and F7 (ISO ePM1 55%) filters, designed to protect your system and improve indoor air quality. Whether you’re looking for original Vallox filters or affordable house brand alternatives, all our options are quality-tested and fully compatible with Vallox MVHR units.
Model compatibility
This category includes filter sets compatible with all major Vallox MVHR ventilation units, including:
- 096 MV/SE/SC series
- 101 MV series
- 110 MV/SE series
- 145 MV/SE series
- 245 MV series
- 51 MV / 51K MV series
- TSK Multi series
- 90 SE / SC / MC 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 Vallox units are designed to ensure optimal air quality and system performance by combining three filters with different filtration roles. Each set includes:
- G4 filters (ISO Coarse 75%): one on the extract side and the other one acting as a pre-filter on the 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%) 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 Vallox filters are manufactured in Finland, a leader in ventilation solutions. 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.
What is the Vallox filter set number, and where do I use it?
Vallox groups its filters into numbered sets — for example, set No. 27 fits the Vallox 096 and ValloPlus 270, and set No. 28 fits the Vallox 145 and ValloPlus 510. Our product titles include the set number next to the model names, so if you know your set number you can match it directly. If not, find the model name on the unit's label and search by that.
Do all ValloPlus models use the same filter size, or does it change with airflow rating?
No. Each ValloPlus size takes its own filter set: ValloPlus 270 uses set No. 27, ValloPlus 350 No. 22/24, ValloPlus 510 No. 28 and ValloPlus 850 No. 29. Match by the model name on your unit's label.
My Vallox control panel shows a filter alert — what triggers it?
Vallox's digital controllers estimate saturation from one or two signals:
- Running hours
- On some models, pressure across the filter
It's a useful prompt, but a quick visual and airflow check is still worth doing, particularly in the first year of a new installation.
What filter classes do Vallox units use?
Most Vallox filter sets are three-piece G4+G4+F7 sets: two coarse G4 filters that protect the heat exchanger, plus a fine F7 (ePM1) filter for the supply air. Some older ILMAVA models use different combinations, such as G1+G1+G4 or G4+M5+F7, so match your set by model or by the Vallox filter set number.
Which Vallox models does your filter range cover?
We stock filter sets for Vallox's residential range — ValloPlus 270, 350, 510 and 850, numbered Vallox models such as 096, 110, 145 and 245 MV, Digit, TSK Multi and older ILMAVA units — widely installed across Finland and the wider Nordic market. The model name is printed on the unit's label.
