No. Disinfection by ArrowMAX Home is not a chemical process. UV utilizes strong short-wavelength (250–280 nm) energy to inactivate microorganisms by damaging the nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. UV process alone does not alter the water chemistry and will not affect the taste or odour of your water. If you are installing the optional pre-filter from Acuva, pre-filter will improve the taste or odour of your water. We recommend installing a pre-filter before Acuva ArrowMAX Home.
