The Ubbink Ubiflux Vigor W325/W400 G4 Filter Set is a pack of two factory-grade G filters designed for use with Ubiflux Vigor W325 and W400 MVHR ventilation systems. These filters act as pre-filters, protecting the unit from coarse airborne particles and helping maintain efficient, reliable system operation.

G filters are intended for environments with normal dust levels and are used to capture larger particles such as dust, pollen, and fibres before they reach the heat recovery core. This reduces internal contamination and supports consistent airflow throughout the system.

For optimum indoor air quality, Ubbink recommends using G filters in conjunction with F filters. While the G filter handles coarse particles, the F filter provides fine particulate filtration, removing up to 99% of dust as well as pollen, mould, and spores. This combination is particularly beneficial for homes with allergy sufferers or sensitive airways.
