Our pick because the cert chain is the cleanest at this price point: NSF 42 for chlorine reduction, NSF 61 for tank-material safety, plus WQA on the contaminant claim chain. The bundled package (pre + conditioner + post) is what AquaSana sells as the complete system and what the $1,123 Amazon listing covers. AquaSana sells a newer WH-1000 model on their DTC site at ~$1,998; the EQ-1000 is the older, still-supported model at the more accessible price.
