Having used Brita dispenser for 20 years in NYC, I bought a new Zerowater 30Cup dispenser from Bed Bath Beyond tonight. The 5 stages filter quality is much better than my Britra filter. My tap water is 34 ppm in NYC. It drops to 0 ppm after Zerowater 5 stage filter comparing to 30 ppm after Brita filter.  Water taste great. I suppose to give 5+ star for ZW water filter.  However, the ZW dispenser white Flip-top cover design poor.  One of the 2 hinges to  the white Flip-top Lid cover arrived broken.  Not sure how long the white Flip-top Lid cover can hanging there by a single fragure hinge.  The spigot has lots of opportunity to improve due to its water leaking minor issue.  The new 30 Cup dispenser spigot cannot stop water right away. It always 9 up to 15 drops leaking after the spigot turn off.  I have to put my glass below its water spigot 1 more minute after the spigot turn off. Spigot water leaking stop fully after that.
