This 3 part filter set is for the H2X Therapool 13 Swim Spa. 

The 78" x 66" Hot Tub Cover (Long-edge Fold) is an exact Master Spa Factory OEM replacement. It is specifically designed to fit your Master Spas® hot tub. This cover is extremely energy efficient, as it's made of a 1.5-pound foam density, six-inch thick foam insulation (which tapers to 4-inches along the sides), and a full-length heat seal. It has been upgraded to include two rubber grip handles and is made of a high quality marine-grade vinyl covering that is mildew treated.

Note: This particular cover folds along the longer 78" edge. If you need a cover with these same dimensions (66" x 78") but that folds along the short edge, try our 66 × 78 Inch Hot Tub Cover (Short-edge fold).
