QCA SPA FILTERS:
Filters should be washed out regularly and replaced every year or two depending on spa usage. Maintaining your filter will result in cost savings and better water quality and is an easy step to assure problem-free operation of your spa.
Spa filters come in many shapes and sizes, so be sure to know your filter model type or measured size to assure accurate replacement. Below is a handy chart for many of our filters in our various spa / hot-tub models.
