Turn the Fluoride filter over and prime the opposite end (reversing the flow of water) repeating steps 3-5 until water runs clear from both directions. 8. To determine if the filter is fully primed, collect the filtered water in a clear glass and hold it up to the light to see if all of the cloudiness is gone from the water, if not continue priming until water is clear. 9. This filter is now primed and ready to install. 10.
