91-105 of 176Keep your ventilation system supplied with cleaner air using a correctly sized Komfovent filter set. Our range covers original Komfovent filters and quality-tested, EU-made house brand alternatives for residential and commercial MVHR units. Shop by model, compare filter grades and choose the option that matches your unit’s specification.
Whether you need a replacement for a Domekt R 400, Domekt R 600, Domekt CF 700, Kompakt REGO or a larger Verso unit, the safest route is to match the complete model code and filter dimensions before ordering. Product listings show the set quantity, sizes and filtration class so you can buy with confidence.
Find the right Komfovent filter for your ventilation unit
Komfovent makes several ventilation-unit families, and filters that look similar are not automatically interchangeable. A Domekt filter must fit the frame and seal correctly to prevent air from bypassing the filter media. Even within the same family, the letter and control-system suffix can identify a different configuration.
Match the complete model code – not only the family name
Check the rating label on the casing, the commissioning documents or the maintenance manual. Record the full name exactly as shown. Details such as R, CF, F, H, V, C6M or C8 matter because they can indicate the heat-exchanger type, unit orientation, generation or controller. For example, a Komfovent Domekt R 450 V C6M filter should be selected against that complete designation, not simply against ‘Domekt 450’.
- Domekt R and CF models: verify the number, airflow orientation and controller suffix. Common searches include Domekt R 200 V, R 300 F C8, R 400 F/H/V, R 450 V C6M and R 600 H/V.
- Kompakt models: identify whether the unit is a REGO or RECU model and retain any number or letter suffix from the label.
- Verso models: use the full CF, R or S designation and the complete model number, particularly for larger commercial units.
- Filter size: use length x width x depth as a cross-check, but let the compatible model listing and unit documentation remain the final authority.
Browse by Komfovent model family
Use the dedicated collections to narrow a large catalogue quickly:
- Shop Komfovent Domekt filters for Domekt R, CF, S and P series units.
- Shop Komfovent Kompakt filters for compatible REGO and RECU models.
- Shop Komfovent Verso filters for Verso CF, R and S ventilation units.
Original Komfovent filters or EU-made house brand alternatives?
Both routes are designed to make routine maintenance straightforward. Original Komfovent filters are the manufacturer-branded option, produced in Lithuania to Komfovent’s specifications. They are a natural choice when you prefer original packaging or want to follow an original-equipment purchasing policy.
Our house brand Komfovent filters are made in the European Union by selected manufacturers and quality checked for compatible fit and reliable filtration. They can offer better value for regular replacement while retaining the model-specific dimensions and stated filter performance shown on the product page.
- Choose original when manufacturer branding, original specification or internal procurement rules are the priority.
- Choose house brand when you want a compatible EU-made replacement and a more economical maintenance option.
- Compare like for like by checking model compatibility, dimensions, set quantity and filter class – not price alone.
Always use the exact product specification and your unit documentation as the final check before purchase.
M5 and F7 Komfovent filter sets explained
Many Komfovent replacement sets use M5 filters, an M5 + F7 combination or another model-specific arrangement. M5 and F7 are familiar EN 779 class names; newer product information may also show ISO 16890 ratings such as ISO ePM10 or ISO ePM1. The exact percentage can vary by filter, so check the individual listing rather than assuming every M5 or F7 product is identical.
M5 / ISO ePM10 filtration
An M5-type filter is commonly used to capture larger airborne particles such as dust, pollen, mould spores and pet dander. In many two-filter MVHR systems, this grade helps protect the unit on the extract side and may also be specified for the supply side. It is a practical option where the manufacturer calls for balanced, general particulate filtration.
F7 / ISO ePM1 filtration
An F7-type supply filter is intended for finer particulate filtration and may help reduce exposure to fine dust, smog, combustion particles and smoke carried in outdoor air. This can be particularly relevant near busy roads, during pollen season or where local air quality is a concern. Because a higher-efficiency filter can create different airflow resistance, fit only a grade approved for your Komfovent model.
For a deeper comparison of older and newer classifications, read our guide to MVHR filter classes. It explains EN 779 terms alongside ISO 16890 particle groups so you can interpret product labels more easily.
How often should Komfovent filters be replaced?
As a practical starting point, inspect the filters regularly and plan replacement every 3-6 months. The best interval depends on the property, airflow setting and surrounding environment. Follow your Komfovent manual and any filter-change alert shown by the controller.
- Replace sooner near heavy traffic, construction, industry or during periods of high pollen and wildfire smoke.
- Check more often in homes with pets, indoor smoking, allergy sensitivities or high occupancy.
- Look for warning signs such as visibly loaded media, reduced airflow, persistent odours or increased fan noise.
- Do not wash disposable filters because moisture and handling can damage the media, distort the frame and reduce performance.
Delaying routine maintenance can restrict airflow and make the fans work harder. See what can happen when MVHR filters are not replaced on time for a fuller explanation of the comfort, airflow and running-cost consequences.
Keeping one correctly matched spare set on hand makes seasonal maintenance easier. Check filters before spring pollen peaks and after nearby building work, decorating or unusually smoky conditions. If a filter loads faster than expected, do not solve the problem by choosing a lower grade without checking the unit guidance. First confirm that the intake grille is clear, the filter is seated correctly and the airflow setting is appropriate. A simple replacement log – date, model, filter class and observed condition – helps you learn the right interval for the property and order the same verified set next time.
How to order the correct Komfovent replacement filter
- Find the unit label. It is normally on the casing or behind the service panel. Photograph it so the complete model code is easy to compare.
- Select the model family. Start with Domekt, Kompakt or Verso, then choose the matching series and number.
- Confirm every suffix. Check orientation and controller details such as F, H, V, C6, C6M or C8 where they appear.
- Compare the product specification. Verify extract and supply dimensions, filter class, number of filters in the set and stated compatibility.
- Ask before ordering if uncertain. Send a clear label photo and existing-filter measurements to our filter support team. We will help you identify the closest matching listing.
When the new set arrives, switch the unit off and follow the instructions under the product page’s ‘How to change’ tab. Note the airflow arrows or supply/extract positions before removing the old filters, fit the replacements without forcing the frames, close the unit securely and reset the filter timer if required.

Weβve gathered answers to the most common questions about our products and services. If you canβt find an answer here, please contact us directly.
How do I find my Komfovent model number?


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.
Are Komfovent filters interchangeable between different models?


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.
How often should I replace my Komfovent filters?


The standard guidance for Komfovent units is every 3β6 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 β treat it as a useful prompt alongside the calendar interval, not a replacement for it.
What is the difference between original and compatible Komfovent filters?


Both are built to meet the same requirements, but they differ in a few practical ways:
- Certification β both original and our compatible filters are tested to ISO 16890 filtration classes
- Manufacturing β 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 β compatible filters are typically priced well below the Lithuanian-made originals
- Fit β 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.
Can I replace Komfovent filters myself?


Yes β on Domekt, Verso and Kompakt units, filter replacement is designed to be tool-free:
- Open the front access panel or filter compartment cover
- Note the airflow direction marked on the old filter's frame
- Slide out the old filter and wipe down the housing if it's dusty
- Insert the new filter in the same orientation and close the panel
The process typically takes just a few minutes, and most units don't require powering down first β check your manual if you're unsure.
