The hygger USB Single Sponge Filter is a compact aquarium filter for small tanks, combining a replaceable microporous sponge and ceramic-ball filtration without requiring an air pump.

• Microporous sponge and ceramic-ball filter media — provide physical and biochemical filtration in sequence.
• Two replaceable sponges and one ceramic-media box — include a spare sponge for ongoing filter maintenance.
• Adjustable tube and sliding clip, plus a suction cup — let you position and direct the outlet in the tank.
• Two outlet styles and S or M size guidance — help match the filter to different aquarium setups.

This filter is made for aquarium owners who want powered water circulation and sponge filtration in a compact setup. Its adjustable outlet can be positioned above or below the water surface, while the included outlet options support different flow arrangements.

How does the hygger USB Single Sponge Filter filter water?

Water passes first through the microporous sponge, then through ceramic balls in the filter box, before flowing out through the extension tube. The sponge’s layered structure provides a broad filtering surface, while the ceramic media provides the second, biochemical filtration stage.

The electric design operates without an air pump, avoiding the air-pressure fluctuations that can affect water flow when an unsuitable pump is used.

• The sponge captures impurities as water passes through it.
• Ceramic balls absorb and help break down impurities.
• Water exits through the selected outlet.

What filter media are included, and how do I maintain them?

The hygger filter comes with two replaceable sponges and one media box containing ceramic filter material. Rinse and soak all filter media before the first use.

Clean or replace the sponge every 2–4 weeks. Check and clean it sooner if water flow becomes significantly weaker or stops. The replaceable components let you maintain the filtration stages as part of regular aquarium care.

• Two sponges are supplied, including an extra spare sponge.
• One box holds the ceramic filter media.
• Rinse and soak all media before installing it for use.

How does the filter fit and direct water flow?

The hygger filter has a retractable tube and sliding clip for adjusting outlet height, and the outlet direction and filter base can rotate. A suction cup helps secure its position inside the aquarium.

Choose between the rain pipe outlet and the duckbill-style aeration outlet head. The adjustable outlet can sit above or below the water surface to suit your setup. For tank capacity, the suggested S size is for tanks smaller than 10 gallons, and the M size is for tanks smaller than 30 gallons.

• Adjust outlet height with the retractable tube and sliding clip.
• Rotate the outlet direction and filter base.
• Select the outlet style and size to suit your tank arrangement.

Which aquariums is this filter suited to?
