Worth knowing
Price recorded is the $399.99 MSRP for the black AQ-CWM2-B; Aquasana showed $184.99 on Oct. 9, 2026. Filters come only in 2-packs at $73.49 one-time; each is rated 300 gallons or about 6 months, so one pack is recorded as 600 gallons or 12 months. Not the older AQ-CWM, whose filter is the AQ-CWM-R-D.
