With a standard 4-inch diameter design and 200 micron filtration rating, AAL Filter aquarium filter socks provide an excellent balance between filtration efficiency, dirt-holding capacity, and water flow performance. The needle-punched PP felt media creates a three-dimensional filtration structure that improves particle capture efficiency while extending service life.

Our products are also widely used as replacement filter socks for popular aquarium sump systems, providing reliable alternatives with competitive pricing and consistent quality.

Features

1. High-Efficiency Mechanical Filtration

The 200 micron aquarium filter sock is designed for efficient removal of suspended particles from aquarium water, including:

· Fish waste particles

· Uneaten food

· Organic debris

· Sand and sediment

· Floating impurities

By removing solid contaminants before biological filtration, these filter socks help improve water clarity and support healthier aquatic environments.

2. Premium PP Felt Filter Material

Made from high-quality polypropylene felt, the filter media provides excellent durability and reliable filtration performance.

Key advantages include:

· Excellent chemical resistance

· High mechanical strength

· Low moisture absorption

PP felt is widely used in aquarium filtration because of its safety, durability, and effective particle removal capability.

3. High Dirt-Holding Capacity

The needle-punched felt structure forms a depth filtration network that captures particles throughout the entire filter media thickness. Compared with traditional mesh filter socks, PP felt filter bags provide higher dirt-loading capacity and longer operating cycles.

This makes them an ideal choice for aquarium systems requiring continuous mechanical filtration.
