I posted this in the portable spa forum but I may have better luck with this one: Last year I purchased a Coast Spas Wellness II Swim Spa. During the winter I foolishly threw out the filter without taking down its info (manufacturer, size, OD, ID, etc). Would anyone here happen to know the correct size and type filter for this spa? It is supposedly a 2012 model.

I bought a Coast Spas Wellness II Swim Spa last year, but after closing it for the winter, I foolishly threw out the filter without taking down the pertinent info like size, OD, ID, etc. would anyone know what size filter this swim spa takes?
