Unicel C-5423 Replacement Filter Cartridge for 34 Square Foot Marquis Spas, Old Style,White

Fits perfect in my old Pacific Marquis. Bought this same filter 2 years ago and could still use it. Decided just to get a new one. A lot cheaper and better than at local pool dealer.

Works great, good quality

It took a long time to arrive, but it fits our hot tub perfectly. Good quality.
