1-9 of 9Discover our range of replacement filters for your Mitsubishi ventilation unit, all made in the EU! Our selection includes high-performance G4 (ISO Coarse 60%) filter sets, designed to protect your system and improve indoor air quality. Whether you’re looking for original Mitsubishi filters or affordable house brand alternatives, all our options are quality-tested and fully compatible with Mitsubishi MVHR units.
Model compatibility
This category includes filter sets compatible with all major Mitsubishi MVHR ventilation units, including:
- Lossnay VL series
- Lossnay LGH-RVX series
- Lossnay LGH-VX 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
Our replacement filter sets for Mitsubishi units are designed to ensure optimal air quality and system performance through a combination of G4 filters with different filtration roles:
- G4 filters (ISO Coarse 60%) on the extract and supply side: ideal for capturing larger particles like soil particles, large pollen grains, plant debris, insect wings, sawdust, sand and textile lint.
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
The original Mitsubishi filters are manufactured in the Netherlands by Mitsubishi’s trusted European partner, guaranteeing authenticity and consistent quality. Our carefully developed house brand filters are also made in the European Union by certified manufacturers. Both are produced with high-quality materials, under strict ISO 16890 standards to ensure high filtration performance and reliability.

Does Mitsubishi’s Lossnay technology require special filters?


No. Lossnay is the name of Mitsubishi Electric's heat-recovery ventilation line and its heat exchange element — the filters themselves are conventional G4 filters that keep dust off the Lossnay core. We stock sets for the Lossnay VL-250, VL-350 and VL-500 (originals) and the LGH-15RVX to LGH-100VX (house brand). The model number on the casing label confirms the exact size.
Which filter class is used as standard in Mitsubishi Lossnay units?


The Lossnay filter sets we stock are all G4. VL-series units and the LGH-15RVX take a set of two G4 filters, while the larger LGH-25RVX to LGH-100VX take a set of four. G4 protects the Lossnay core from coarse dust and keeps airflow steady.
How often do Mitsubishi Lossnay filters need to be replaced?


Lossnay units follow the standard 3–6 month interval, although many models have a built-in maintenance indicator that warns when airflow drops due to a dirty filter. It's worth treating this indicator as a useful reminder rather than the only criterion for when to replace the filter — especially in urban environments or near busy streets, where the filter gets dirty faster than the calculator suggests.
Do filters fit across different generations of Mitsubishi Lossnay units, or only within the same series?


Filter compatibility generally stays within the same series and the same housing generation, but Mitsubishi has changed internal filter dimensions in some model updates, even while keeping a similar product name (e.g. within the VL or LGH-RVX series). The safest approach is to choose a filter based on the exact model number, or, if you can't find it, to measure the old filter directly before ordering a new one.
Why do some Lossnay filter sets contain four filters?


The larger Lossnay LGH units — LGH-25RVX, 35RVX, 50RVX, 65RVX and 100VX — take four filters in total, so our sets for these models include all four G4 filters. Change them together to keep the airflow balanced. The LGH-15RVX and the VL-series units take two filters.
