Introducing Evolution Aqua's latest innovation in pond filtration technology, the K+Advanced Filters. Manufactured by Evolution Aqua in the UK, this new range of pressure filters have been specifically designed to use Evolution Aqua’s own filtration media, K+Media, to deliver exceptional water clarity and to be economical to run.

Key Features

• Manufactured to last using latest rotational moulding process for peace of mind
• Supplied with advanced  K+Media, delivering enhanced mechanical and biological filtration
• Economical to run. The filter has been engineered to maximise pump efficiency
• The colour matches existing Evolution Aqua filters
• Easy to operate and clean, with pipework, blower and multiport valve supplied.

Best-in-Class  Filtration Media

The benefits of using K+Media  have been well documented since its launch in 2019, including its ability to filter particles down to one micron. The design and profile of the media helps to improve flow, its vast protected surface area of 1,025m2 per m3, or the total area of 5 x tennis courts, maintains stable bio-films and its unique manufacturing process where minerals and enzymes are added during the extrusion process, ensure K+Media matures faster than any other type of filtration media. Evolution Aqua's filter media has also been independently tested to verify its performance by IFTS and Cranfield University.

Peace of Mind

Because Evolution Aqua are in control of the manufacturing process they can put the filters through rigorous testing and quality control checks before leaving the factory. K+Advanced Filters are rated to a maximum working pressure of 1.5 bar.

Economical to Run

To optimise performance, there are unique double laterals inside the filter that help to improve flow through the bed of K+Media, that is supplied with every filter. This laminar flow, coupled with the use of K+Media reduces back pressure on the circulating pump, ultimately making K+Advanced Filters one of the most economical filters to run.

Easy as 1-2-3

They are simple to install and can be used as a standalone filter or as part of a larger filtration system with a Nexus+ or on a skimmer line. The K+Advanced Filters are incredibly easy to clean and are supplied with K+Media, pipework, air blower and multiport valve.

How K+Advanced Filters work?

Water is pumped into the filter from the pond, through the multi-port valve where the internal pipework directs the water to the bottom laterals.

As the water flows upwards inside the K+Advanced Filter, dirt, debris and waste are trapped within the mass of K+Media that floats at the top of the filter. The vast protected surface area provided by K+Media also provides a home for beneficial bacteria, delivering mechanical and biological filtration.

The filtered water flows back through the laterals and pipework at the top of the filter, through the multi-port valve and back down the return line into the pond.

The K+Advanced Filter, is incredibly easy to clean by simply moving the handle on the multi-port valve into the corresponding positions to perform a backwash and rinse which flushes out the waste trapped inside.
