Product review (1 stars): Water had undesirable odor/taste - like cool plastic
Once in a while Dad's efforts to save a buck back fire.  This was one of those deals for me.

We liked the expensive KitchenAid OEM filter results, but apparently it's no longer available.  I thought I'd try OnePurify for the low price, but wife and kids hated the very noticeable taste.  Upon install, I flushed the system (until water ran clear), then used the system for a few weeks, and even tried flushing again (3+ gallons).  Unfortunately the difficult to describe but very noticeable bad odor/flavor persisted.  I know water varies by source - our source is EBMUD in Contra Costa County, CA so perhaps your results will vary.  I finally gave in to family requests and purchased a more expensive filter (~$50).  The water is clear, clean and odor free again!  Peace has been restored.
