Wellis whirlpools are among the leaders on the European market and are known for their modern design, sophisticated ergonomics and advanced features. But even the best hot tubs need one key thing – reliable filtration to ensure that the water remains hygienically clean, clear and odourless.
And this is where we run into a common problem – cartridge filters, which, while standard, often fail to keep up with the performance and durability demands of today’s users. Their filtering capabilities are limited, they require frequent replacement and they cannot effectively capture the smallest impurities, bacteria or odours.
In response to increasing demands for water purity and hygiene, we have developed an advanced three-layer microfiltration media that not only significantly outperforms standard cartridge filters, but is also fully compatible with all Wellis whirlpool models – without the need for technical modifications.
Our new type of filter is designed with an emphasis on maximum efficiency, easy maintenance and long service life. It consists of a unique combination of three specialized filter layers that ensure high performance at every stage of water purification:
Absorption Microfilter (white layer) – captures solid particles and impurities from as little as 3 microns, providing up to 10 times the efficiency of conventional cartridge filters.
Silver Microban Active – an antimicrobial layer containing silver ions that prevents the growth of bacteria, mould and biofilm formation, keeping the water hygienically clean.
Carbon Odour Absorber – a specially designed microfibre with activated carbon that neutralises odours and leaves water fresh.
However, it is important to emphasize that the functionality of this advanced microfiltration medium is conditional on the use of a special Royal filter. It is this filter that ensures the correct water circulation, mechanical fit and pressure conditions under which the medium can reach its maximum efficiency. The Royal filter thus forms an integral part of the entire system and guarantees that the individual layers of the medium function exactly as they should.

Unlike traditional cartridge filters that require frequent replacement, our filter media is reusable. Simply wash it in the washing machine once in a while – short programme, 15 minutes at 30 °C without detergent – and it is ready for use again.
The lifetime of the media is up to 12 months, after which you can dispose of it in an environmentally friendly way – because it is 100% recyclable. Thanks to reusability, you significantly reduce both costs and your ecological footprint compared to conventional disposable cartridge filters.
