How Simple Are Direct Connect Filter Changes?

If you have not yet changed a Pure Blue H2O Direct Connect System Single-Stage filter you may not realize just how simple changing the filter actually is. Filter changes essentially only require turning the water off, quarter turning the old filter out from the manifold head, and quarter turning the new filter into the manifold head.

Installation is outrageously simple also. This process by no means requires a plumber. It is possible to complete the entire installation in 3 steps, as seen below:

Once installation is complete you can enjoy filtered drinking water directly from your kitchen faucet. The recommended filter change frequency is every 4 to 5 months.

The complete manual for our Direct Connect Water Filtration System is available for download here: Direct Connect Size 4 Manual. Additionally, for your convenience, here is our Direct Connect Installation Guide Video. The video includes our simple twist lock filter change instructions:
