There are 2 choices for replacing the water filters and reverse osmosis membrane on your DuPure -60 blue reverse osmosis system or Dupure -60 blue under counter drinking water filter system.

 

1.  You can order the filters below in blue.  These fit the original Omnipure-60 Blue thread pattern.  Perfect fit!

2.  You can replace the -60 threaded heads in the filter system and start using the same filters and RO membranes with standard threads.  The Dupure systems with Omnipure -60 blue filters are a different thread patern than the standard series, so they are not interchangeable.  

To start using the lower cost standard filters, simply replace your DuPure Omnipure -60 blue ® or Raine Pure Blue ® -60 Threaded Omnipure ® 2 stage water filtration system's -60 blue threaded head and start using the standard threaded Omnipure ® "Q" series replacement water filters at a lower cost than the -60 blue thread.

Since both systems use John Guest ® quick connectors it is very easy to install the replacement standard threaded head. Keep your old DuPure faucet, tank and feed valve. See information on how easy it is to use ® John Guest quick connectors.
