How to choose
Stages and what they add
Stages count the filtration steps water passes through: the AquaTru uses 4 stages and the Bluevua uses 6 stages, including UV light and a remineralization filter. The Berkey uses 2 filter elements in a gravity system instead of numbered stages. A higher stage count alone does not settle the choice; compare what each stage removes, and the Bluevua reduces TDS, PFOA, PFOS, chlorine, fluoride, arsenic and lead.
Power, plumbing and placement
Each system sits on a counter with no plumbing: the AquaTru plugs into a standard outlet, the Bluevua plugs into any power source, and the Berkey needs no electricity at all. The Bluevua shows filter life on a monitor display.
Filter life and upkeep
Filter life is given in months, years or gallons, so compare the same unit across picks: the AquaTru pre/carbon filter lasts 6 months or 300 gallons. The Bluevua filters last 12-24 months, and the Berkey element pair provides up to 6,000 gallons. The Bluevua monitor display shows the service life of filters. For upkeep, note what comes out: the AquaTru carafe is removable with a lid, and the Berkey upper chamber nests inside the lower chamber for storage.
