SUNSUN Garden pond pressure filter 11W UV CPF-3500

The SUNSUN CPF-3500 is a compact pressure filter designed for small ponds, ornamental pools and aquariums where maintaining good water quality and limiting algae growth are important. It is fitted with an 11 W UV-C lamp that supports the cleaning process and helps keep the water clear. The filter is compatible with pumps delivering up to 7000 l/h, has a filter chamber capacity of 20 litres and includes connectors for hoses of different diameters. According to the manufacturer it suits fish ponds up to 4 m³ and fish-free ornamental ponds up to 8 m³.

Combining mechanical and biological filtration, the unit removes suspended particles, sediment and organic waste from the water. Beneficial bacteria colonise the inside of the filter, supporting natural biological cleaning and creating more stable conditions for fish, plants and other pond life.

The 11 W UV-C steriliser helps limit the algae responsible for green and cloudy water. Ultraviolet exposure causes algae to clump into larger particles that the filter media can then capture, making the pond clearer and easier to maintain. Its pressure-driven design allows discreet installation at the pond edge or partial burial in the ground, so it blends into the garden.
