Vita Spa PVT 50WH Filter Cartridge
Vita Spa OEM number • 50 sq ft • 8.5″ OD × 7.0625″ long
PVT 50WH is Vita Spa's number for this cartridge, not a part you have to buy from Vita Spa. The filter itself is a 50 square foot cartridge measuring 8.5 inches across and 7.0625 inches long, and Pleatco, Unicel, and Filbur all build it. If you read PVT 50WH off an old cartridge or found it in your manual, any of the numbers below drops into the same housing.
Fitment notes
Handle top with Pleatco's F2L fitting on the bottom, a long 2 inch male NPT adapter. Unicel reaches the same cartridge from Vita's own PVT 50WH and publishes its 8CH-502 as 8-1/2 by 7-1/4 inches at 50 sq ft, with a v-groove semi-circular handle top and a 2 inch male pipe thread, for models dated 2006 to present. This is the threaded sibling of the PVT50W, which is the same 8-1/2 inch body with open ends instead. Unicel adds that the 8CH-502 also covers earlier slotted-bottom cartridges once the pad adapter is removed from the skimmer.

Each button searches Amazon for one of the numbers this cartridge is sold under. The OEM version is usually the most expensive of the set and the aftermarket versions are the same physical filter, so it is worth checking all of them before you order.

Frequently Asked Questions
What filter replaces the Vita Spa PVT 50WH?
The PVT50WH-F2L replaces it directly, and so does every cross-reference for it: 8CH-502. All of them are the same 50 sq ft cartridge at 8.5" outer diameter and 7.0625" long. Buy whichever is cheapest at the time with solid recent reviews.
Is the Vita Spa PVT 50WH the same as the PVT50WH-F2L?
Yes, physically the same filter. Vita Spa PVT 50WH is an OEM number, meaning it is the code Vita Spa put on the cartridge that shipped with the equipment. Vita Spa does not manufacture cartridges. Pleatco, Unicel, and Filbur do, and they sell the identical part under their own numbers at a lower price. Match the dimensions against your old cartridge before ordering and you are covered.
Do I have to buy the Vita Spa version?
No. Nothing about the housing requires an OEM-branded cartridge, and the warranty on your equipment is not voided by using an aftermarket filter that meets the same spec. The reason to buy OEM is convenience, not performance. The reason not to is price, which is often a meaningful gap for an identical part. What matters is that outer diameter, length, and end-cap style all match.
What size is the Vita Spa PVT 50WH?
8.5 inches in outer diameter, 7.0625 inches long, with 50 square feet of filter media. Both measurements need to land within about an eighth of an inch, and the end caps have to match so the cartridge seats correctly when you close the lid. Measure your old one rather than trusting a number that has worn off the label.
