How do I set up my ProOne gravity filter for the first time?

Scrub each filter under cold running water without allowing water to go inside the blue stem. After scrubbing your filters, cycle 3 batches of water through them and dump the water. Start drinking your water on the fourth cycle for the best taste.

How do I prep my ProOne gravity system for travel?

Allow your filter elements to dry out, then wrap them in a cloth and store them in a safe place. If you store filter(s) inside the gravity system, make sure they have ample padding to prevent breakage.

How often should I clean my gravity systems and filters?

We recommend cleaning your systems and filters at least once a month.

When and how should I store my filters?

If you are not using your filters or system for more than 4–7 days, drain the water and air-dry the filters. Wrap the filters in a terry cloth towel and store them in a cool, dry place. Do NOT put them in a plastic bag or any enclosed container.

How many filters should I use?

Each ProOne G2.0 filter has a general lifespan of up to 6 months with daily use. Using more filters at a time will increase their lifespan and flow rate at the same time. Using 3 filters at a time will provide the fastest flow rate.
