What makes this 50 sq. ft. cartridge so popular is that it is the optimum size for the typical quantity of water found in a hot tub. 

If you compare this square footage to that used in a typical swimming pool cartridge filter, it will seem that the spa filter is over-optimized so that even a 25 sq.ft. filter will clean the water beautifully.

In fact, some people prefer the 25 sq.ft. over the 50 sq. ft. because it is lower in cost while it still fits the same filter canister.  However, the 50 sq. ft. filter does have twice as much filter media and consequently twice as many filter pleats.
