Simple UV bulb replacement


The new generation of Filtoclear Pressure Filters allows you to remove the bulb with ease while the unit is still operating.

Reminder: It is recommended to replace UV bulbs every 12 months, after this time the UV quality dramatically diminishes which can result in your pond turning green.

Simple to clean


The internal filter sponges can be cleaned conveniently and thoroughly using the patented pull-out mechanism; without needing to open the filter: To do this, pull the cleaning handle several times. The sponges are compressed and any dirt will come loose. Then simply flush the filter and drain off the dirty water. The integrated UVC lamp can also be easily changed even while running via the filter head.

Simple to install


The FiltoClear pressure filter can be placed anywhere outside of your pond. Just dig the FiltoClear into the ground. Then connect the hoses to the filter pump and return flow – that’s it. Both beginners and professionals will benefit from the simple installation.

A closer look at the technology


What is a pressure filter and how do I set up the filter system?

Pressure filters maintain the pump pressure of the upstream filter pump throughout the system. This also allows a higher water return flow to be created, for example in the form of a watercourse. Pressure filter systems always consist of two components: Firstly, the filter pump in the pond, which carries the dirty water to the pressure filter. Secondly, the pressure filter. We sell FiltoClear on its own or as a set with the AquaMax Eco Premium filter pump. There is also the option of adding a surface skimmer to your filter system. The skimmer is connected to the filter pump in the pond.

How does the FiltoClear pressure filter work?

The upstream filter pump constantly transports the water to the FiltoClear. First, filter sponges with various pore sizes inside the pressure filter provide mechanical and biological cleaning. Clarifying microorganisms can settle particularly well on the fine-pored sponges. The water then reaches the centre of the filter. There, a powerful UVC lamp removes bacteria, floating algae and microorganisms. The purified water leaves the FiltoClear and flows back into the pond via an elevated watercourse.

FiltoClear pressure filters are available in four sizes for volumes of water between 5000 and 31,000 litres. Simply refer to the number in the product name – this number indicates the maximum recommended volume for a pond without fish. For a pond with fish, it’s best to choose a higher performance class. You can find a selection guide in the product details.
