Sunsun (HBL-801 | HBL-802 | HBL-803) Hang-on Aquarium Filter

Powerful Filtration with a Compact Design ? Ideal for Modern Aquariums

The SunSun HBL-801 Series Hang-On Filters (801, 802, and 803) combine efficient 3-stage filtration, built-in surface skimmers, and whisper-quiet performance in a slim, hang-on design ideal for freshwater tanks ranging from 40 to 150 liters. Whether you?re keeping tropical community fish, planted tanks, or bettas, these filters are engineered to support a healthy, clear aquatic environment with minimal effort.

The HBL-801 series uses a multi-layer filtration system ? including mechanical sponges, biological chambers, and chemical media to effectively remove waste, odors, and harmful toxins while encouraging beneficial bacteria growth. The integrated surface skimmer eliminates surface film and oils, improving oxygen exchange and boosting water clarity.

With adjustable flow control, these filters allow you to fine-tune circulation to suit different fish species or planted environments. Despite their strong performance, the energy-efficient motors (3W?5W depending on model) ensure low running costs and near-silent operation.

Installation is quick, thanks to the sleek hang-on design that fits securely on most aquarium frames. Maintenance is easy with slide-out media trays that let you rinse or replace filter media without removing the entire unit.
