The Ubbink Ubiflux Vigor W325/W400 G4 Long-Lasting Filter is a durable pre-filtration filter designed for use with Ubiflux Vigor W325 and W400 MVHR ventilation systems. It plays a key role in protecting the unit by capturing coarse airborne particles before they enter the heat recovery core.
G4 filters are intended for environments with normal dust levels and are effective at removing larger particles such as dust, fibres, and pollen. This long-lasting version offers extended service life, helping reduce maintenance frequency while maintaining consistent airflow and system efficiency.
For optimum indoor air quality, Ubbink recommends using G filters alongside F filters. While the G4 filter provides reliable pre-filtration, an F filter delivers fine particulate filtration, removing up to 99% of dust as well as pollen, mould, and spores—particularly beneficial for allergy sufferers and sensitive airways.
