Before replacing the filters, it is recommended to read the unit’s user manual. During installation you must follow the direction of the airflow – the arrows printed on the filter must point towards the rotor (heat exchanger).
Ensure that the filter sits firmly in the frame and that there are no gaps around the edges where air could bypass the filter.
Filter position in L and R versions
- L version: the supply air (outdoor air) filter is on the right
- R version: the supply air filter is on the left
This applies to all DOMEKT R400V C6M units (with C6M controller).
Important compatibility information
These filter sets are compatible with the following KOMFOVENT model:
- DOMEKT R400V C6M (with C6M controller)
NB! Do not confuse with:
- DOMEKT R400V (older version)
- DOMEKT REGO 400
The filter dimensions, frames and filter sets are different, and the filters on this page are not suitable for R400V (non‑C6M) or REGO 400 units.
In addition to the model name, you can distinguish the units by the door locking system:
- DOMEKT R400V C6M (newer model) – the front door has black plastic locks
- DOMEKT R400V (older version) – the front door has metal locks that are opened with a key
Using the wrong filter size may cause:
- air bypassing the filter (leakage)
- higher energy consumption
- reduced indoor air quality

- make sure the filter frame sits straight and seals well, without gaps
Filter positions:

- R version: supply air filter on the left
How often should I replace the filters in my DOMEKT R400V C6M?
Recommended replacement interval:
- 1–2 times per year in residential applications
- more frequently if:
- you live in a high‑traffic or polluted area
- there are construction works nearby
- your home has a lot of dust or pets
Replace the filters earlier if they are visibly dirty or if the unit shows a maintenance / filter alarm.
Can DOMEKT R400V C6M filters be used in other Komfovent models?
In general, no. Filters are designed for specific models and dimensions:
- These sets fit DOMEKT R400V C6M (with C6M controller) only.
- They do not fit DOMEKT R400V (older version) or REGO 400 units.
Always check the exact model name of your unit and the dimensions of the existing filters before ordering. If you are unsure, contact us at: info@filters24.eu.
What is the difference between original and compatible filters?
- Original filters – approved by Komfovent and fully match the manufacturer’s specifications.
- Compatible filters – manufactured in the same dimensions and filter classes, fit into the same filter slots and provide a comparable filtration level.
Compatible filters are often a more cost‑effective solution while still maintaining the required filtration class and correct fit.
