Replacing Your Vita Spa Filter
Power off the spa, then remove the existing cartridge from the skimmer. Some Vita Spa filters have threads like this one above, while others do not. Then replace with your brand new filter and enjoy. It is best to measure your existing filter to be sure the dimensions are about the same and verify the thread is the correct thread type if the filter opening requires a threaded connection. Most threaded connections found on Vita spas are of the MPT or fine thread type (vs. SAE which is course threads).
The smaller Vita Spa Duet model (2 person hot tub) uses a removable cartridge located in the filter canister behind the weir door. The manufacturer recommends monthly inspection and cleaning of the spa filter since a clogged filter reduces performance. The manufacturer recommends soaking the filter in an overnight filter soak cleaning solution.
