If your DuPure Reverse Osmosis filters do not have similar filter numbers on them, then we recomment using the Omnipure Q-5621 as the prefillter and the Q5640 as the post filter. You can select either of the two RO membranes we have listed. Don't forget to order the Standard Omnipure Heads!

DuPure International® uses Omnipure® Q-Series filters in their Pure Blue Reverse Osmosis System and Pure Blue Drinking Water System. The difference is that they have a different thread size to their filters. This is what the "-60" means.

We recommend that you simply replace the valve head with standard Omnipure® heads. Then you can use standard Omnipure filters in your system and save money on replacement filters. This costs less than a single DuPure® filter replacement, is simple to do and in no way alters the performance of the system. Other than the thread size, there is no other difference between the filters.

To convert your Q-60 series system to a standard Q-Series unit (so that standard Q-Series system filters and membrane can be used) simply purchase one of our standard valve heads. There is no need to replace your existing RO faucet, cold water feed line valve, drain clamp or RO storage tank. The substitution is easy. Simply remove the four screws that hold the valve head to the bracket and screw on the Standard Omnipure® Q-Series Filter Head.
