Find the Right Hot Tub Filters for Your Spa

Master Spa filters are designed to match each series, so choosing the right one depends on your model:

  • Twilight Series: Uses EcoPur Charge filters with outer cartridges. Newer 2025 models require updated filter designs.
  • Michael Phelps Legend Series: Shares many filter types with Twilight; confirm year and part number for proper fit.
  • Healthy Living Series: Compatible with EcoPur Charge filter sets; 2025 spas may need redesigned outer filters.

Always check your spa’s model year and part code to ensure compatibility.

FAQs

Q1: How often should I replace my hot tub filter? 

A hot tub filter replacement is typically recommended every 12–18 months, depending on usage and water quality, to maintain proper sanitation, system performance, and long-term equipment protection.

Q2: Can I clean my spa filter instead of replacing it?
Filters can be rinsed regularly and deep-cleaned with approved solutions, but replacement remains essential. Over time, fibers degrade, reducing efficiency, making scheduled replacement the only way to ensure consistent water quality.

Q3: What’s the difference between a Master Spa filter and a generic spa filter?
Master Spa filters are engineered to precise specifications, ensuring correct fit, performance, and durability. Generic filters may lack proper materials, dimensions, or technology, leading to reduced water clarity and potential equipment strain.

Q4: How do I know which hot tub filter fits my model?
Each Master Spa model requires specific filter dimensions and part numbers. Checking your spa’s owner manual or product label ensures proper compatibility, while our team can confirm the exact replacement filter.
