Note: Buckets Not Included - #10 cans to wastebaskets can be used as long as container is suitable for potable water.
To retain a constant capacity always add the same amount of water to the filter sleeve that you will be dispensing from the reservoir.
Remove the filter and clean the filter sleeve and water reservoir (buckets) every two weeks with hot water. Clean the filter with a soft tooth brush or 3m pad and cold water. (never use hot water and soap on filter). Re-install filter and proceed as normal.
It usually takes several days for the flow rate to increase to 1 gallon per hour. The flow rate will increase as the interior and mixed media becomes completely saturated. If flow rate is slow, clean filter and keep filter sleeve full.
Once you start using the filter, the activated carbon is only good for 6 to 8 months. The anti-bacterial ceramic wall will work indefinitely. The media inside (such as the activated carbon) will pack over time. The filter needs to be shaken to unpack the media. The shelf life of the unit itself is indefinite. The only question in the carbon. Current figures say the unused carbon should have a shelf life between at least 2 or 3 years, if not much more. The sock has an indefinite shelf life. Replacement during use will depend on filthiness of the water source.
