Arctic Spa Silver Sentinal Filters - Any generic replacements??

[Gibson00]

I think my local shop here in Canada charges roughly $140 for a 4 pack of the silver sentinal threaded disposable filters......are there any cheaper generics available online that will work??

I'm an Arctic Spa Dealer.  You can goto a pleated fitler Unicel 4ch-949 (If you have a closed top and screw on the bottom) or Unicel C-4950 (if there is a hole all the way thru your filter).  These filters don't filter as well but do last longer (as long as you clean your filters on a regular basis).
