To achieve optimal protection against PFAS,our best recommendation is to pair the FilterWall ™ F5 for whole house filtration, along with the RO270 reverse osmosis under sink system for ultra fine filtration.By connecting the FilterWall ™ F Series to your mains water inlet, you gain access to filtered water across your whole house for healthy drinking and bathing water. This means your daily exposure to PFAS is significantly reduced across all interactions with water. To further secure optimal drinking water, installing the RO270 under sink reverse osmosis filter will effectively separate chemicals from water with the use of the ultra-fine membrane. Reverse Osmosis is our best partner against PFAS, flushing all contaminants and reducing up to 96% of all dissolved impurities, heavy metals, salts, viruses, bacteria, cysts, fluoride, nitrate, chlorine, taste, odour and chemicals.
