Features

• FILTRATION PRINCIPLE: ① The water flows through the microporous filter sponge, absorbs impurities in the water. ② The water continues to flow through the ceramic ball, absorbing and decomposing impurities. ③The filtered water then passes through the extension tube and flows out through the water outlet
• REPLACEABLE FILTER SPONGE: The first level is physical filtration. The water flows through the microporous filter sponge. The multi-layer design has a larger surface area, full filtration without dead ends, strong water permeability, and is easy to absorb impurities in the water
• REPLACEABLE BIO-BALLS: Second level biochemical filtration, water continues to pass through the small filter box with ceramic balls, precipitates impurities, effectively absorbs and decomposes bad impurities. Please rinse and soak all filter materials before use
• FILTER CLEANING: Two kinds of replaceable filter materials, with a total of 2 sponges, and 1 media boxes with ceramic filters. The filter sponge should be replaced or cleaned every 2-4 weeks, or if the water flow is significantly weakened or off, the filter sponge should be checked and cleaned immediately
• USB ELECTRIC SPONGE FILTER: no need to use with air pump, an inappropriate air pump will cause unstable air pressure and water flow, affecting water circulation and poor filtering effect. The electric design effectively solves this problem, with strong power, stable water pressure and better filtering and purification effect
