Keep Your Tank Crystal Clear with the Mini Hang-On Aquarium Filter

Upgrade your aquarium with this compact, USB-powered hang-on filter — engineered for effortless installation, quiet operation, and superior water quality in both freshwater and saltwater tanks. Whether you're a first-time fish keeper or a seasoned aquarist, this mini suspended filter makes clean, oxygenated water simple to achieve.

Key Features

• Natural Waterfall Flow for Enhanced Oxygenation: A widened outlet platform simulates a gentle waterfall effect, boosting oxygen levels while slowing water flow. The unique bump design extends filtration contact time, promoting a healthier aquatic environment.
• Adjustable Flow Rate: A simple dial knob lets you precisely control water flow to suit your tank size and the needs of your fish — from small betta bowls to larger community aquariums.
• USB Powered for Flexibility: Compatible with any USB power source — phone charger, laptop, or portable power bank. Energy-efficient at just 2.5W, and can keep running during power outages when paired with a power bank so your fish always have a steady supply of oxygen.
• Compact & Space-Saving Design: The slim, mini body hangs directly on the aquarium wall without occupying tank space. No tools or complicated setup required — just hang, fill with water, and connect.
• Easy Cleaning & Maintenance: Fully detachable design allows you to quickly remove, rinse, or replace the filter sponge. Routine maintenance is fast and hassle-free.
