Great Lakes Spa Filters Canada

Great Lakes FiltersReplace your cartridge filter annually on your Great Lakes Spa.  Popular hot tub filter models include:

Some Great Lakes Spa filters have a top handle and a bottom threaded connector such as:

  • Spa filter compatible with 4CH-50, M40503 ,PTL50, FC-0151 measuring 14 3/4″ long and diameter 4 3/4″ wide with top handle and bottom 1 1/2″ MPT threaded connector
  • and also a smaller 4CH-30, PTL25, FC-0141 measuring 11 7/8″ long and diameter 4 5/8″ wide with top handle and bottom  1 1/2″ MPT threaded connector

At first glance, it may appear like the filter compartment has a large lid, but this is actually the ice bucket or ice chest located in the spa in addition to cup holders. This is a sample of what a Great Lakes hot tub looks like.
