Patented Spiral 3D Structure

More surface area is covered by spiral and coarse filaments, aids in beneficial bacteria cultivation and upgrades bio filtration efficiency.

Moderate Thickness and Density

Circulates more oxygen and organic material to keep bacteria active and prevent clogging.

Solid Structure Made by Hot-melting

Made of eco-friendly material by hot-melting, safe for water, UV and sunshine resistant, and more durable.

Easy to cut, maintain and install

Can be cut according to different sizes of the filtration system. The moderate density makes it easy to maintain and clean.
