Practical but unaesthetic? Beautiful but totally impractical? Our Stelvio filter box puts an end to lazy compromises. Conceived and made in the Polyfaser-Manufaktur in South Tyrol, this box plays all the pieces and looks outrageously good at the same time. This is due on the one hand to the timelessly elegant "RAL 9007 grey aluminium" colour, and on the other hand to the simple, unobtrusive design language. Stelvio fits every pool, every style, every garden. Guaranteed!


A flexible filter box that lasts for decades. 

Whatever we build at Polyfaser, it should (and will!) deliver what we promise. Thanks to its extremely robust construction - let's just say: frame made of powder-coated aluminium profiles and fillings made of weather-resistant aluminium composite panels - you can be sure that your filter system is optimally protected. What's more, our Stelvio filter box makes life easier for you: with a double-winged door and a hinged lid, a practical rotary toggle with cylinder lock, adjustable feet and variable fastening struts and an invisible ventilation system.
