Hot Spring-compatible filters from SpiroPure use advanced point-bonded pleated media to capture particles and maintain water clarity effectively. Pleated media creates a larger surface area to capture debris, hair, oils, lotions, and other particles while maintaining flow rates. Periodic rinsing helps keep water moving, and regular replacements combined with good water chemistry ensures peak water quality. Since SpiroPure filter cartridges match Hot Spring performance specifications and sizes, when you find a compatible filter at All Filters you'll get the same quality filtration for less than OEM filters.
