Measure spa filter for accurate replacement.If you don’t know the model number, it is best to measure your existing filter to make sure you get the correct replacment. 

You may find your filter model number by searching by brand below, but you still need to confirm the measurements as filters may have changed for any given model.

Next Best Method to Find a Spa Replacement Filter

If you don’t know the filter model number, then you can measure the length, width (outer diameter) and inner hole width (inner diameter) to determine the filter size that will fit.  You will then need to make note of both ends (top and bottom) to make note of any closed ends, handles, threaded connectors on the bottom end etc.. that may be different than the standard top and bottom hole through the middle type of filter.  Know the dimensions of your spa filter but not the model number? 

See our Spa Replacement Filter by Dimensions page to find out what Master Deluxe filter fits your spa.  Make note of the top hole and bottom hole details (if it has a hole, what the inner diameter measures, if not is there a handle or is it closed at the top?  Does it have a standard hole at the bottom or is there a threaded connection that screws into the filter housing?  All this information is included in the Spa Replacement Filter by Dimensions chart.

Third Best Way to Find a Spa Replacement Filter

If you don’t know the filter model number, then you should find your replacement filter by measuring the one you have. If you can’t do that, then you can try to order by spa model – but know that sometimes spa manufacturers change the filter canisters within the same spa model to accept a different style filter, so this method is less accurate than having the filter model number or measuring the filter.
