The Ubbink Ubiflux Vigor W225 G4L Filter is a factory-grade pre-filter designed to keep your Ubiflux MVHR system running smoothly, efficiently, and reliably. This G4 filter is used to capture coarse airborne particles before they enter the heat recovery unit, helping to protect internal components and maintain consistent airflow.

Manufactured to meet ISO Coarse ≥ 60% (G4) standards, the filter effectively removes over 60% of larger dust particles such as pollen, textile fibres, and general airborne debris. This not only improves system performance but also extends the lifespan of the MVHR unit by reducing internal contamination.

For optimum indoor air quality, Ubbink recommends using G filters in conjunction with F filters. While the G4 filter handles coarse particles, the F filter removes up to 99% of fine dust and can also capture pollen, mould, and spores—particularly beneficial for allergy sufferers.
