Brand
Fluval
Fluval's own site states that Fluval is part of the Hagen Group, the family-operated business founded in 1955 by Rolf C. Hagen.
Fluval's canister filters use a family of replacement media rather than a single sealed cartridge. Because the 06 and 07 Series share much of that media, one product is often listed for several filter sizes.
