Vita Spa PVT 50 Filter Cartridge
Vita Spa OEM number • 50 sq ft • 7.0625″ OD × 14.8125″ long
PVT 50 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 7.0625 inches across and 14.8125 inches long, and Pleatco, Unicel, and Filbur all build it. If you read PVT 50 off an old cartridge or found it in your manual, any of the numbers below drops into the same housing.
Fitment notes
Semi-circular handle top with Pleatco's push-in PAD adapter on the bottom, the tall 50 sq ft Vita Spa cartridge. Unicel lists its 7CH-50 for Coleman Spas and Vita Spas together at 7 by 14-3/4 inches, reaching it from Vita's own PVT 50, and adds that you should remove the pad adapter from the skimmer before threading the Unicel part directly into the suction fitting. This is the same cartridge Pleatco sells to Coleman owners as the PCS50, under Coleman OEM 100434, which is where that number is recorded on this site.

Replacements for the Vita Spa PVT 50
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 50?
The PVT50P replaces it directly, and so does every cross-reference for it: 7CH-50, FC-0463. All of them are the same 50 sq ft cartridge at 7.0625" outer diameter and 14.8125" long. Buy whichever is cheapest at the time with solid recent reviews.
Is the Vita Spa PVT 50 the same as the PVT50P?
Yes, physically the same filter. Vita Spa PVT 50 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 50?
7.0625 inches in outer diameter, 14.8125 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.
