Aquarium Polyurethane Filter Sponge (Biochemical Cotton, Reusable, Cut-to-Size)

🐾 Product Overview

Aquarium polyurethane filter sponge — biochemical cotton, reusable, cut-to-size — this aquarium polyurethane foam filter sponge provides both mechanical particle capture and biological bacteria colonization surface area in a cut-to-size format that accommodates any filter configuration, with reusable washable material for long service life and polyurethane construction for durability. Polyurethane foam offers a different performance profile than standard filter sponge — it has a finer, more consistent cell structure that provides better mechanical filtration while maintaining open porosity for flow-through, making it particularly effective as a polishing-stage filter media after primary mechanical filtration.

✨ Key Benefits

• 🔬 Fine Filtration — Polyurethane cell structure for mechanical and biological filtration.
• ✂️ Cut-to-Size — Custom trim for any filter housing or sump tray.
• ♻️ Reusable — Wash and reuse for extended service life.
• 🦠 Bio Surface — Cell structure supports beneficial bacteria colonization.
• 💧 Biochemical — Combined mechanical and biological filtration in one media.

📦 What's Included

• 1x Polyurethane filter sponge sheet

📏 Specifications

• Material: Polyurethane foam
• Feature: Cut-to-size, reusable, biochemical filtration, washable

💖 Why You'll Love It

Cut-to-size filter media provides the freedom to fit filtration precisely to any filter housing rather than compromising with pre-cut pads that may be the wrong shape or leave gaps around the edges — gaps around filter media bypass particles around the filtration surface rather than through it, reducing effectiveness regardless of the media quality. Polyurethane foam maintains its structural integrity through many wash cycles better than standard open-cell foam, which can tear or compress over time and reduce its filtration effectiveness. The biochemical dual function — mechanical particle capture and biological bacteria colonization — means a single media type provides both critical filtration functions, simplifying media selection and reducing the number of different media types needed in a filter system.
