Our selection includes high-performance filter sets available in G4 (ISO Coarse 65%) or F7 (ISO ePM2.5 70%), designed to protect your system and improve indoor air quality. Whether you’re looking for original Itho Daalderop filters or affordable house brand alternatives, all our options are quality-tested and fully compatible with Itho Daalderop MVHR units. Model compatibility
This category includes filter sets compatible with all major Itho Daalderop MVHR ventilation units, including:
- HRU ECO 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 Itho Daalderop units are designed to ensure optimal air quality and system performance by offering separate sets with G4 or F7 filters:
- G4 filters (ISO Coarse 65%) 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.
- F7 filters (ISO ePM2.5 70%) on the extract and 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 Itho Daalderop filters are manufactured in the Netherlands, combining Dutch engineering precision with high standards of indoor comfort, air quality, and environmental responsibility. 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.

Which Itho Daalderop heat recovery units do you have filters for?
We supply filters for the two most popular Itho Daalderop series:
- HRU (including the HRU ECO and HRU ECO 150/200/350 models) — a standalone balanced ventilation unit
- WPU — ventilation integrated with a heat pump system
Both series are widely used in new-build homes in the Netherlands. You'll usually find the exact model code on a sticker under the unit's front cover, next to the filter compartment.
Which filter class fits the Itho Daalderop HRU ECO 350?
The HRU ECO 350 and similar HRU models usually come with two F7-class filters — one on the supply air side and one on the extract air side, although some variants use a simpler G4 filter on the extract side. F7 (ePM1) class captures fine dust and pollen, making it suitable for more sensitive households. Check the exact set (F7+F7 or F7+G4) against your specific model code, as different HRU variants can differ.
Does the WPU series’ integration with the heat pump change how often filters need maintenance?
The ventilation filters themselves are maintained independently of the heat pump function, but in WPU systems the ventilation runs continuously, supporting both heating and air quality. As a result, the filters can accumulate more running hours per year than in standalone HRU units — it's worth checking them more often, closer to the 3-month mark rather than 6 months.
What’s the difference between original and compatible Itho Daalderop filters?
Both options are made to fit the same HRU or WPU housing geometry and the same filtration class (usually F7):
- Original filters — manufactured to Itho Daalderop's specifications, often more expensive
- Compatible (equivalent) filters — made by other EU manufacturers to the same dimensions and ISO 16890 class, at a lower price
Using a correctly sized, correctly classed compatible filter does not affect the unit's warranty, since the filter is a regularly replaced consumable part, not a structural component.
How do I find out the exact model of my Itho Daalderop unit?
To order the correct filters, knowing just the series name (HRU or WPU) isn't enough — you need the full model code:
- Open the front cover — the code is usually shown on a sticker next to the filter compartment
- Check your installation documents or purchase invoice
- If you can't find the code, measure the old filter (length, width, thickness) and compare it with the dimensions in our catalogue
The exact code ensures the new filter fits snugly into the housing and doesn't let unfiltered air leak in around the edges.
