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 filter class fits an Itho Daalderop HRU ECO unit?
For each HRU ECO size we stock two original sets:
- G4+G4 — coarse filters on both sides, the standard option
- F7+F7 — fine F7 (ePM1) filters that also catch pollen and fine dust
The F7 set is the better choice for allergy sufferers or homes near busy roads.
My Itho Daalderop HRU ECO filter indicator is on — what should I do?
The filter indicator on HRU ECO units is a maintenance reminder. Check the filters, fit a new set if they are dirty — which they usually are after 3–6 months — and reset the indicator as described in your manual. Resetting it without changing the filters only postpones the reminder while airflow keeps dropping.
Which Itho Daalderop units does your catalogue cover?
We stock original filter sets for the Itho Daalderop HRU ECO range — HRU ECO 150/200 and HRU ECO 350 — one of the most widely installed balanced ventilation units in Dutch new-build housing. The model code is usually printed on a sticker inside the unit's front cover.
How fast can you deliver Itho Daalderop filters within Austria?
In-stock Itho Daalderop filters are dispatched within 24 to 48 hours and typically arrive in Austria in about 3 to 4 business days. We keep both filter classes for HRU ECO units in stock rather than ordering them in for each request, so a rarer brand does not have to mean a long wait — only clearly marked made-to-order items take 5 to 10 business days.
Do the HRU ECO 150/200 and HRU ECO 350 use the same filters?
No. The HRU ECO 150 and 200 share one filter size, while the HRU ECO 350 takes a different set. Check the model code on the sticker inside the front cover before ordering, then choose G4+G4 or F7+F7 in the matching size.
Itho Daalderop is not a common brand in Austria — can you still supply the filters?
Yes. Itho Daalderop is a Dutch manufacturer and its HRU ECO units are far more common in the Netherlands and Belgium than here, but we still stock original filter sets for the HRU ECO 150/200 and HRU ECO 350, each as G4+G4 and F7+F7. In-stock filters are dispatched within 24 to 48 hours and arrive in about 3 to 4 business days by UPS, DPD or GLS, with free delivery from €100; only clearly marked made-to-order items take 5 to 10 business days. Because these units are rarely seen by Austrian installers, it is worth confirming before you order — send the model from the type plate or the dimensions of the old filter and we'll check the match.
