Two-Stage PFAS Water Filter for Under the Sink, Model Activo Duo Ultra+


The Activo Duo Ultra+ water filter solution comes with a CTO coconut-based activated carbon block pre-filter and a UF Pro coconut-based activated carbon block main cartridge with an integrated ultra-membrane filter at 0.1μm.


With the two activated carbon block cartridges combined with ultra-membrane filtration, similar to what is used in reverse osmosis filtration, you have the ultimate filtration and protection against a wide range of impurities, such as PFAS, bacteria, viruses, and virtually all other contaminants that could potentially be present in drinking water in Denmark. Despite the effective filtration, healthy minerals remain in the water.


To remain effective against PFAS, both cartridges need to be replaced after a maximum of 6 months or 5000 liters.


The filter housings are made of food-grade stainless steel and come with all hoses, fittings, and wall brackets for easy installation.


The Activo filter housing has been tested and approved by SGS Switzerland and meets the highest international standards, including ROHS, NSF, and FDA. Additionally, it complies with European standards and has achieved TÜV certification, Australian Watermark, and meets the requirements of European REACH regulations.
