DOMEKT REGO 400 PE / REGO 400 PW filter sets – F7 art. 774300005, M5 art. 774132408
Filter size: 278 × 258 × 46 mm
NB! These filters are also used in the DOMEKT R400F unit, but do not fit the newer DOMEKT R400F C6M model or DOMEKT R400V / R400H – the filter dimensions and sets are different and are not interchangeable.
In this category you will find both original and high‑quality compatible filter sets for the Komfovent DOMEKT REGO 400 PE and REGO 400 PW ventilation units. The same filters are also compatible with several REGO and R‑series units listed below. The filters are manufactured according to the manufacturer’s specifications and ensure:
- very good indoor air quality
- stable and quiet operation of the unit
- energy‑efficient performance
Compatible (non‑original) filters are produced in the same dimensions as the originals and fit precisely into the filter slots of the unit (278 × 258 × 46 mm).
Recommended filter combination: F7 + M5
For standard residential use, the manufacturer generally recommends the following filter combination:
- F7 / ePM1 60% – supply air filter (outdoor air)
- M5 / ePM10 50% – extract air filter

Compatibility – which units do these filters fit?

NB! These filters do not fit the newer DOMEKT R400F C6M model, DOMEKT R400V or DOMEKT R400H. Those units use different filter dimensions and different filter sets.
Always check the exact model name on the unit’s nameplate and the dimensions of the existing filters before ordering.
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 compatible DOMEKT REGO 400 / REGO 250 and R250F / R400F units using these filter dimensions.

- F7 / ePM1 60% – fine filter that captures most fine particles, pollen and allergens. Recommended for the supply air.
- M5 / ePM10 50% – medium‑class filter that captures coarser dust and larger particles. Usually used as the extract air filter to protect the unit and heat exchanger.
