Our experts were impressed by the AquaTru Connect’s three-filter system, which effectively eliminates over 80 contaminants, marking one of the highest numbers among the water filters subjected to our testing.

Upon data review, all three filters demonstrated their efficacy in removing the claimed contaminants. The pre/carbon filter tackles particles like sediment and rust, along with chlorine, enhancing the water’s taste.

Concerns about filter replacement timing are alleviated with the accompanying smartphone app, which conveniently tracks this information.
