Collection: Roller Filters & Fleece Rolls

Mechanical Filtration That Advances Itself

A roller filter holds a spool of fleece across the water path and winds fresh material through as the used section clogs. The job a filter sock does — trapping detritus before it breaks down — happens the same way, minus the part where you remember to swap and wash the sock. What it buys you is consistency: the fleece is never more than slightly loaded.

What's in This Collection

• Automatic roller filters — sized from nano units up to models built for larger sumps.
• Cartridge-style fleece filters — a fixed housing with a fleece roll feeding through it.
• Replacement fleece rolls — matched to specific units, and in widths and micron ratings for cartridge housings.
• Mesh filter material — reusable sheets that can be cut to size.
• Sump modification kits for fitting a roller unit into an existing sump.

Before You Buy

• Check the roll. Refills are model-specific; width and length matter more than brand loyalty here.
• Measure the sump section the unit sits in, including the height you need above it to load a fresh roll.
• Budget for consumables. A roller filter is an ongoing fleece cost rather than a one-off purchase.
• Fleece is mechanical only. It catches solids; it does not remove what has already dissolved.
