Pre-Filter for Pro Filters |Arctic Spas| 2020 to present Custom Series

NOT COMPATIBLE WITH NEW POLAR PRO FILTERS!!!!

This is the Pre-Filter for the Progressive Filters used on the Arctic Spa Custom Series from 2020 through the present.  Use the Pre-Filter if your water contains contaminants or is cloudy.  The Pre-Filter snaps into the top of the Progressive filters.   Put the entire filter back into the filter housing with the skimmer on top.  You will see water going over the top of the skimmer when the pump is on and it is in the filtration cycle.  Once the water stops flowing over the top of the skimmer, remove the Pre-Filter.
