Customer Reviews

Sturdy & Cost-Saving

Looks just like the pricier ones. This filter has thicker end caps holding the pleated paper, so it feels sturdier. I am happy with this and will purchase again.

Joseph

Fits Perfectly

Fits perfectly in my spa’s filter holder. The material feels high-quality and holds up well. With a second one included, it’s a great value and handy to have a spare ready. Definitely recommend.

Provides Good Filtration & Water Flow

These filters stop lint, dirt, and body oils from harming my hot tub components. I found these filters to work very well in filtering and allowing proper jet flow. Easy to clean and reuse.
