Brofer RDCD50SH filters

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.

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.

We recommend the standard 3–6 month interval for Brofer units, checked more frequently in the first year after installation to establish how quickly your specific environment loads the filters. Homes with pets or nearby renovation work should lean toward the 3-month end of that range.

Keep unopened Brofer filters ready for installation by following a few simple storage rules:

• Leave them in their original packaging until you're ready to install
• Store in a dry, room-temperature space
• Keep away from direct sunlight and moisture

Filter media can absorb ambient humidity if left unwrapped for long periods, which slightly reduces its dust-holding capacity before it's even installed.

Using a correctly sized, ISO 16890-compliant compatible filter does not affect your Brofer unit's mechanical or heat-exchanger warranty, since filters are a routine consumable part rather than a structural component. Manufacturer warranties typically only require that filters meet the correct class and dimensions, not that they carry the original brand name.

Yes, and more than most inland customers would guess. Along the Belgian coast the outdoor air carries a fine salt aerosol as well as wind-blown sand, and both load the supply filter faster than in an inland town — noticeably so during the windy autumn and winter months. Salt-laden dust that gets past a saturated filter is also harder on what lies behind it than ordinary household dust. If you are within a few kilometres of the sea, check the Brofer filters monthly through windy periods and plan for the shorter end of the 3–6 month range rather than the longer one. Keeping a spare set at home makes acting on what you find much easier.
