Caldera Spa Filters

Depending on the year of your spa, Caldera filters PCD50 and PCD75 have two different versions. There is PCD50 & PCD75, and PCD50N & PCD75N. The difference is, that the cartridge models ending in N have no raised lip on the bottom of the filter. Newer models (N) have a flat bottom.
