Komfovent Domekt R 300 V C6/C8 filters

The full model code is usually printed in one of a few places on your unit:

• On a nameplate on the unit's front or side panel, often near the power connection or control panel
• On a sticker inside the front cover, next to the filter compartment
• In your installation documentation or original purchase invoice

Any of these will give you the exact code needed to match the correct replacement filter, rather than relying on the series name alone.

Not as a general rule. Komfovent's Domekt, Verso and Kompakt (REGO/RECU) ranges each use different filter housing shapes and sizes, and even within the same series, filter dimensions can vary between compact and larger-capacity variants. Always match by your exact model code or measured filter dimensions rather than assuming a filter from one model will fit another.

The standard guidance for Komfovent units is every 3–6 months, in line with typical ISO 16890 filter loading. Consider checking sooner if:

• You have pets or nearby renovation or construction dust
• A household member is allergy-sensitive, especially during high-pollen season
• The property is in an urban area near busy roads

Most Domekt and Verso controllers also display a maintenance reminder based on running hours or pressure drop — treat it as a useful prompt alongside the calendar interval, not a replacement for it.

Both are built to meet the same requirements, but they differ in a few practical ways:

• Certification — both original and our compatible filters are tested to ISO 16890 filtration classes
• Manufacturing — Komfovent's originals are produced at their own facility in Lithuania, while our compatible alternatives are made elsewhere in the EU to the same standard
• Price — compatible filters are typically priced well below the Lithuanian-made originals
• Fit — both are cut to the exact Domekt, Verso or Kompakt housing dimensions

Using a correctly sized, correctly classed compatible filter does not affect your unit's warranty, since filters are a routine consumable part rather than a structural component.

Both, because they describe the same performance under two different standards. The older EN 779 used the familiar G, M and F classes; ISO 16890 replaced it and classifies filters by how efficiently they capture particles in the ePM10, ePM2.5 and ePM1 size ranges. The 2020 edition of ÖNORM H 6038 includes a translation table between the old and new designations precisely so this comparison can be made, and an F7 filter corresponds to an ePM1 filter in roughly the 50–65% range. For a Domekt unit, order by the dimensions and the class on the old frame; if both match, the designation on the box is a labelling difference rather than a different product.

Yes — on Domekt, Verso and Kompakt units, filter replacement is designed to be tool-free:

1. Switch the unit off
2. Open the front access panel or filter compartment cover
3. Note the airflow direction marked on the old filter's frame
4. Slide out the old filter and wipe the housing if it's dusty
5. Insert the new filter in the same orientation, close the panel and reset the filter timer on the controller

The whole process typically takes just a few minutes.
