Fluval U4

Finest Filters stock a complete range of compatible foam and polycarbon filter cartridges to fit the Fluval U4 Filter. We are also pleased to now offer our own compatible biomax for efficient biological filtration in your Fluval U4 filter. We offer bundle sets of our filter media which offer the best value compared to buying parts individually. Our foam pads, polycarbon filter cartridges and biomax are made to the same specification as the original brand filters.
