How often should I change my filters?
A good indicator its time to replace your filters is if you notice a slowdown in the flow rate or taste/smell of your water is noticeably different. You could clean the filters first, but if after cleaning the flow rate does not increase or you still notice the difference in taste/smell then it is time to replace the filters.
Remove your filters from the upper container. Hold the filter by the blue plastic base. Place the ceramic portion under cool running water for about 2 minutes. Scrub the white ceramic material with the abrasive side of the included sponge. Rinse well. Do NOT use any soap on the filter. Do NOT allow water to enter the stem of the filter. Lay filters on the side until ready to install.
How should I store my filters?
Properly storing your filters is important when your system is not in use. If not using your system for a week or more, remove the lid, drain any water in the upper and lower containers. Remove the ProOne G2.0 water filters from your system and allow it to air dry. Wrap your filters in a terrycloth towel and store in a dry, cool place. Do NOT put the filters in a plastic bag or any enclosed container. Do NOT allow filters to freeze when wet. Do NOT place filters in the microwave oven. When you use your system again, simply reinstall the filters and discard the first supply of water from the lower container. With the ProOne G2.0 filter, it is NOT necessary to keep the filter saturated at all times.
How long can I store water in the lower container?
We recommend you cycle water from the lower container on a regular basis. Do not allow water to sit in a lower container for more than 3 days. Should you need to store water, use an appropriate water storage container.
How do I know how much water is in the lower container?
You can either lift the upper container to see the water level or use a sight glass spigot (optional) which shows the water level in the lower container. Remember to use water from the bottom container before refilling the upper container.
Why is water leaking between the upper and lower containers?
This occurs only when you have filled the upper container with more water than what can fit into the lower container.
Why is my spigot leaking?
Check the placement of the washers and nut. Try to tighten the nut.
How do I clean my stainless steel containers?
Remove the filters from the upper container. Remove the spigot. You may clean the system using mild dish soap or a 50-50% solution of white vinegar and water. Use a sponge or soft cloth. Rinse well and dry. Reinstall the filter and spigot.
How often should I clean my filters and system?
It’s recommended you clean your entire system once a month.
How can I check to make sure my filters are working correctly?
Run the “Blue Food Coloring Test” to ensure your filters are working correctly. You’ll need LIQUID blue food coloring, available at most grocery stores. First, empty any water from the upper and lower containers. Place a clear container or glass under the stem of each ProOne G2.0 water filter in the lower container. Place the upper container on top of the lower container and fill the upper container with water. For the water pitcher and Scout, place (1) drop of blue food coloring and stir. For Traveler +, the Big +, and the Big II systems, place (2) drops of blue food coloring and stir. After a short period of time, check the clear containers. If the water is either clear or slightly tinted, your filter(s) are working correctly. If you see a definite blue tint, the corresponding filter(s) may need to be replaced. You may notice some blue coloring on the ProOne G2.0 filters after performing the test. This is normal and should go away after a period of time, or you may clean the filters.
What if a filter fails the blue food coloring test?
Confirm the placement of your washer is correct. Washer should be on the inside of the upper container, directly below the filter base. Ensure the wing nut is securely tightened on the filter’s threaded stem. Check to verify that the plugs are firmly installed. Plugs may need replacing over time.
