1-9 of 9Discover our range of replacement filters for your Brofer ventilation unit, all made in the EU! „Filtrų pasaulis“ selection includes high-performance filter sets combining G4 (ISO Coarse 65%) and F7 (ISO ePM1 55%) filters, designed to protect your system and improve indoor air quality. All our options are quality-tested and fully compatible with Brofer MVHR units. Model compatibility
This category includes filter sets compatible with all major Brofer MVHR ventilation units, including:
- LQR series
- RDCD series
To ensure the right fit, it’s important to know the exact model of your ventilation unit, as different models require different filters. You’ll find helpful tips on identifying your device in the FAQ section.
Filter types and what they protect against
„Filtrų pasaulis“ replacement filter sets for Brofer units are designed to ensure optimal air quality and system performance through a combination of filters with different filtration roles. Available filter options:
- G4 filters (ISO Coarse 65%) on the extract or supply side: ideal for capturing larger particles like soil particles, large pollen grains, plant debris, insect wings, sawdust, sand and textile lint.
- F7 filters (ISO ePM1 55%) on the supply side: high-efficiency filters that capture very fine particles, including bacteria, smog, tobacco smoke particles, combustion dust, spores, and wildfire smoke particles.
Usage and maintenance
To keep your MVHR system running efficiently and your indoor air clean, we recommend replacing the filters every 3–6 months. However, this depends on your environment, if you have pets, or nearby construction.
To make the process easy, we provide step-by-step replacement instructions for each filter model. You can find them under the “How to change” tab on every product page.
Manufacturing quality you can trust
Our carefully developed house brand filters are made in the European Union by certified manufacturers. They are produced with high-quality materials, under strict ISO 16890 standards to ensure high filtration performance and reliability.

How do I find the right filter for my Brofer heat recovery unit?


Since Brofer heat recovery units (e.g. the RDCD series of plate exchangers) are sold in several different configurations, the safest way to find the right filter is to measure the extract and supply air filter panels directly (length × width × height in millimetres) and compare them with our sizing catalogue. The model code on the label on the unit's front cover will also help narrow the search down to the exact product faster.
What filter classes fit Brofer units?


Residential Brofer heat recovery units usually use the standard M5 and F7 class filter combination, in line with the ISO 16890 standard applied across most European heat recovery systems. Both our original-specification and compatible filters are made to the same tolerance requirements, so choosing between them doesn't affect filtration efficiency or airflow.
How often do Brofer filters need to be replaced?


For Brofer units, the standard recommended interval is 3–6 months, and during the first year after installation it's worth checking the filters more often to see how quickly they clog in your particular environment. For households with pets, or where renovation or construction work is going on nearby, it's advisable to aim for the shorter end of the interval – around 3 months – rather than the full six.
How should I store spare Brofer filters so they don’t lose their properties before installation?


To keep unopened Brofer filters fit for installation, follow a few simple rules:
- leave them in the original packaging until you're ready to install them
- store them in a dry, room-temperature space
- keep them away from direct sunlight and moisture
Filter material that's left unwrapped for a long time can absorb ambient moisture, which slightly reduces its ability to trap dust even before the filter is put into use.
Does using a compatible filter instead of an original one void the warranty on my Brofer unit?


Using a correctly sized, ISO 16890 compliant compatible filter does not void the mechanical or heat exchanger warranty on a Brofer unit, since the filter is considered a normal, regularly replaced consumable part rather than a structural component of the unit. Manufacturer warranty terms generally only require that the filter match the specified class and dimensions – not that it carry the original brand name.
