Advanced NanoFilters™

Capture More Than Ever Before.

It is easy to see the striking difference between the standard filter and NanoFilter. This engineering masterpiece sets new standards with its higher performance filter, ensuring a crystal clear swimming experience.

The Nanofilter's micro-pore spun-bonded polyester fabric creates a mesh that allows water to flow freely while trapping even the smallest particles. Its deep ridges and large surface area effectively capture debris, maintaining optimal water flow.

When it comes to modern robotic pool cleaners, there are two main types of cartridge filters. Unfortunately, the importance of these filters is often missed by swimming pool owners. However, it's essential to shed some light on this crucial component. Filters function through a mechanical process called sieving, which determines which particles are captured and which ones pass through. The traditional filter found in many pool robots relies on a large-pored plastic mesh, which can be considered outdated. But as technology advances, so does the filtration system.

Easy To Clean

Superior Cleaning Ability

Experience the power of the Nanofilter's high-efficiency particulate filtration, ensuring the water you swim in remains free from contaminants. Unlike other filters, Nanofilters excel at removing oil. When oil is trapped, it forms a transparent sheath over the debris, which is easily removed during cleaning. This unique feature improves turbidity and enhances water transparency, leaving your pool water crystal clear and polished. No more cloudy appearances caused by small suspended particles – Nanofiltration is the ultimate solution.
