This spa filter replacement offers excellent filtration and water flow for hot tubs. Customers said it's a "perfect fit" and provides "great quality at a quarter of the cost" compared to original equipment. Most praise fast shipping and competitive pricing. One customer noted improved jet pressure. Minor concern about durability of center support band.

Replaced original ceramic filters.

It was time to replace the 5 ceramic filters that came from the factory when we purchased our new HotSpring Vangaurd spa. The cost of the ceramic filters was very high on a per-unit basis so we decided to go with the lesser-expensive paper filters. They fit perfectly and work as well as the ceramics, maybe even better. We (my wife & I) use our spa daily and run the main jet pumps for about 45 minutes per day. No more ceramics for us.
