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.

We’ve gathered answers to the most common questions about our products and services. If you can’t find an answer here, please contact us directly.
Will upgrading a Lossnay unit from M5 to F7 noticeably reduce airflow or increase fan noise?


A well-matched F7/ePM1 filter is designed to fit the same housing as the standard M5 filter, so any change in airflow resistance is generally small and not noticeable in day-to-day use. If you do notice a drop in airflow or an increase in fan noise after upgrading, it's usually a sign the filter needs checking sooner rather than the upgrade itself being unsuitable.
Are filters compatible across different generations of Mitsubishi Lossnay units, or only within the same series?


Filter compatibility generally holds within the same Lossnay series and housing generation, but Mitsubishi has updated internal filter dimensions across some model refreshes even under a similar product name. Matching by your exact model number, or measuring the filter directly, is the safest way to confirm fit across generations.
How often do Mitsubishi Lossnay filters need replacing?


The standard 3–6 month interval applies to Lossnay units, though the built-in maintenance indicator on many models will flag when airflow has dropped due to filter loading. Treat that indicator as a helpful reminder rather than the sole basis for replacement timing, especially in higher-pollution areas.
What filter class is standard on Mitsubishi Lossnay units?


Most residential Lossnay units offer two filtration levels:
- M5-class filter as standard
- F7/ePM1 available as a supply-side upgrade, for improved allergen and fine dust filtration
Both are compatible with the same filter housing.
Does Mitsubishi’s Lossnay technology need special filters?


Lossnay refers to Mitsubishi Electric's heat exchange element, not the filter itself, so Lossnay-branded units use conventional M5/F7-class filters like other MVHR systems — the name simply identifies the ventilation product line to look for when ordering. The unit's model number, found on the casing label, confirms the exact filter size.
