this is the exact fit filter for our 2008 Jacuzzi J270 Spa---I placed the order online, and it arrived here the VERY NEXT DAY! Always amazing service from you guys----thanks very much! John Westenberg
good filter worth the extra money thier is alot of junk out thier you get what you pay for
Filter fits like a glove and the cost is half that compared to OEM through a dealer.
Fast friendly deal.
