Mitsubishi Lossnay LGH-100RVX filters

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.

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.

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.

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.

Yes, if the company has a valid EU VAT number. Once the number has been verified, prices are shown without VAT (0%) at checkout. A VAT invoice is e-mailed automatically after every purchase — worth checking the spam folder before contacting us — and a pro forma invoice can be issued in advance if your accounting needs one before payment, with the goods shipped once the payment arrives. Lossnay units turn up more often in offices and commercial premises than in Finnish homes, so if you are covering several units at once: above four filter sets, contact us and we will discuss the pricing rather than leaving you at list price.

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.
