The hygger HG908 Small Aquarium Single Sponge Filter is a compact air-driven sponge filter designed for small freshwater aquariums. It provides gentle filtration and surface movement while helping support beneficial bacteria inside the sponge.

This single sponge filter uses mechanical and biological filtration to help trap particles and support stable water quality. The soft sponge and gentle bubbling design make it a good fit for shrimp, bettas, planted tanks, fry tanks, and small tropical fish setups.

The HG908 size S model is rated for small aquariums from 0.5–5 gallons and works with aquarium air pumps in the 1.5–5W range. It is easy to place, easy to clean, and includes one spare sponge.
