Komfovent Verso 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.

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.

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.

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.

In practice, yes. The old EN 779 standard used the G, M and F classes that most people still recognise, and ISO 16890 replaced it, classifying filters by how efficiently they capture particles in the ePM10, ePM2.5 and ePM1 size ranges. An F7 filter corresponds to an ePM1 filter in roughly the 50–65% range. This matters in Finland because current design guidance is written in the new classes — it asks for ePM1 50% supply filtration in normal conditions rather than for "F7" — so a Domekt filter listed as ePM1 is the successor designation, not a different product. Order by the dimensions and the class on the old frame.
