How do I find the right filter for my Brofer heat recovery unit?
Start with the model code on the unit's label — we stock filter sets for the Brofer RDCD25(SK), RDCD35SH, RDCD40SK/RDCD50SK, RDCD50SH and LQR280. If the label isn't legible, measure the extract and supply filters directly (length × width × depth in mm) and match them against the sizes on our product pages.
What filter classes fit Brofer units?
Brofer units use G4 filters to protect the heat exchanger. For the RDCD models we stock two versions: a G4+G4 set, or a three-filter G4+G4+F7 set that adds a fine F7 (ePM1) supply filter for pollen and fine dust. The LQR280 is available as a G4+G4 set.
How often do Brofer filters need to be replaced?
For Brofer units, the standard recommended interval is 3–6 months, and during the first year after installation it's worth checking the filters more often to see how quickly they clog in your particular environment. For households with pets, or where renovation or construction work is going on nearby, it's advisable to aim for the shorter end of the interval – around 3 months – rather than the full six.
How should I store spare Brofer filters so they don’t lose their properties before installation?
To keep unopened Brofer filters fit for installation, follow a few simple rules:
- leave them in the original packaging until you're ready to install them
- store them in a dry, room-temperature space
- keep them away from direct sunlight and moisture
Filter material that's left unwrapped for a long time can absorb ambient moisture, which slightly reduces its ability to trap dust even before the filter is put into use.
Does using a compatible filter instead of an original one void the warranty on my Brofer unit?
Using a correctly sized, ISO 16890 compliant compatible filter does not void the mechanical or heat exchanger warranty on a Brofer unit, since the filter is considered a normal, regularly replaced consumable part rather than a structural component of the unit. Manufacturer warranty terms generally only require that the filter match the specified class and dimensions – not that it carry the original brand name.
Do Brofer filters need changing more often in spring because of pollen in Latvia?
They can. Latvia's birch, alder and grass pollen season runs from roughly April to June, and during those weeks the supply filter – especially a finer F7/ePM1 class – captures a lot more particles than during the rest of the year. If someone in the household has hay fever, check the Brofer filters monthly in spring and replace the supply filter as soon as airflow drops noticeably. Many customers simply plan one of their two or three annual filter changes for the end of the pollen season.
