Filter installation
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).
Make sure that the filter frame sits straight and seals well, without gaps around the edges where air can 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 REGO 400 VE / REGO 400 VW (C4 / C4 Plus controllers) and the older DOMEKT R400V units.
Important compatibility information
These filter sets are compatible with the following KOMFOVENT models:
- DOMEKT REGO 400 VE (C4 / C4 Plus)
- DOMEKT REGO 400 VW (C4 / C4 Plus)
- DOMEKT R400V (older model with C6.1 / C6.2 controllers)
NB! Do not confuse with the DOMEKT R400V C6M model – the filter dimensions, frames and filter sets are different, and the filters on this page are not suitable for the C6M version.
In addition to the model name, you can distinguish the R400V units by the door locking system:
- DOMEKT R400V older model (C6.1 / C6.2) – the front door has metal locks that are opened with a key
- DOMEKT R400V C6M (newer model) – the front door has black plastic locks
Using the wrong filter size may cause:
- air bypassing the filter (leakage)
- higher energy consumption
- reduced indoor air quality

How do I install the filters in my DOMEKT REGO 400 VE / REGO 400 VW unit?
When installing:
- follow the airflow direction indicated on the filter – the arrows must point towards the rotor (heat exchanger)
- make sure the filter frame sits straight and seals well, without gaps

How often should I replace the filters in my DOMEKT REGO 400 VE / REGO 400 VW?
Recommended replacement interval:
- 1–2 times per year in residential applications
- more frequently if:
- you live in a high‑traffic or polluted area

- your home has a lot of dust or pets
Filters should also be replaced earlier if they are visibly dirty or if the unit shows a maintenance / filter alarm.
Can DOMEKT REGO 400 filters be used in other Komfovent models?
In general, no. Filters are designed for specific models and dimensions:
- These sets fit DOMEKT REGO 400 VE / REGO 400 VW (C4 / C4 Plus) and DOMEKT R400V older model (C6.1 / C6.2), but do not fit the R400V C6M model (newer version with black plastic locks).
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.
