Why are Filbur filters better than the rest?

Filbur spa filters are made to the highest standards and specifications demanded by original equipment manufacturers (OEMs) of pools and spas. They are rigorously tested for reliability, performance and quality, and have become the industry standard for premium hot tub filters for more than 20 years.

Here are some of the features that make Filbur filters stand out above the rest:

  • STRONG CORES: Filbur filters for hot tubs are designed with extruded PVC cores, the toughest of its kind in today’s market.
  • PREMIUM MEDIA: All of the Filbur cartridges feature REEMAY filtration media for maximum dirt-holding capacity and flow.
  • DURABLE DESIGN: With their sturdy skeletal frames, thick media covers and strong blue stitching, Filbur filters are specially engineered to endure many seasons of spa use—without compromising on performance.
