  • NSF/ANSI 50 Certified: Tested and certified by NSF International against NSF/ANSI 50 for the use of safe materials. The trilobal pleated design captures 3x more debris than regular fabric, efficiently trapping leaves, hair, sand, and oils for cleaner water
  • Enduring and Long-Lasting: Corrosion-resistant end cap protects against chemical damage and high temperatures without melting. Strong polyester fiber resists deformation and breakage, ensuring multiple uses
  • Easy Maintenance: Trilobal structure repels large particles from entering the inside of the filter, ensuring they are spread out and preventing stains from building up in any one area. This design allows for easy and thorough rinsing
  • Reduce Cleaning Frequency: The free-flowing porous core design promotes even water flow and minimizes clogging, ensuring stable filtration system operation and reducing the need for frequent cleaning. It used to require cleaning every two weeks, now it's once a month

  • A: Clean our hot tub filters monthly. If water quality declines or filtration seems ineffective, replace the filter sooner.

  • A: Start by rinsing the filter with water to maintain its natural conditions. If it's not thoroughly clean, you can then use detergent to help with the cleaning.

  • A: Future Way invests in high-quality materials and advanced technology to maximize filtration efficiency. Unlike generic options that compromise on quality, we focus on enhancing your spa experience and extending your hot tub's lifespan.

  • A: You should not be. Our filters come in standard sizes that will fit perfectly with your pool pump cover. However, if for some reason you are unable to install our filters, don't worry, we are here to help.

The two pack is a convenient arrangement - no delaying the next filter replacement waiting on a new filter to arrive.
