Expensive but got close to 6 months from it. TDS  meter from zero water filter says it removes little from the water. Probably so. Not a discernable difference from tap water. Maybe slightly less chlorine. Worst part about this is I have to flush a glass of water through every morning or if water sits for a while or it acquires a terrible plastic type taste. Not a fan. Do yourself a favor and look elsewhere.
