This product is a high-performance external filter newly designed with innovative design and beautiful appearance. The filter has a multi-layer filtration function and a built-in UV lamp. The filter's integrated inlet and outlet with a stop valve allow the water flow to be shut off and the filter to be detached at any time, making it easy to disassemble and clean. The integrated water pump consumes less energy, operates quietly, and saves power. The scientific design of the four gripping buttons and the water-resistant device ensures the sealing of the filter cover and barrel. The bottom of the filter uses rubber feet to prevent slipping and absorb shocks.
