Overview

Meet the PoolPure PRB35-IN spa filter, a versatile 35 sq ft replacement designed to fit a broad range of hot tubs. Built to endure regular spa sessions, it aims to deliver consistent water clarity and simple maintenance without compromising safety.

Advanced filtration technology

Trilobal filtration fabric creates a larger surface area for dirt and sediment capture. The result is more effective filtration while preserving water clarity during frequent use. A 50 micron layer adds precision for fine particles such as hair and dust.

  • Three times the adsorption surface area of standard fabrics
  • 50 micron high efficiency layer for finer debris
  • Dirt-locking technology simplifies cleaning and extends cartridge life

Durability and safety you can rely on

Durable construction combines 4 oz polyester fabric with reinforced end caps and a strong core. The filter is IAPMO certified under NSF/ANSI 50 standards for material safety and longevity, giving peace of mind for long-term water exposure.

  • NSF/ANSI 50 certified materials
  • PHTA member aligned with industry filtration standards
  • Routinely used by pool owners worldwide for dependable performance

Compatibility and value

This is a compatible part designed to replace Unicel C-4335, Guardian 409-219, and several other 35 sq ft models. It can fit PRB35-IN and related lines, offering a cost-effective option without relying on OEM parts.

Usage tips and maintenance

Rinse the filter during cleaning to release trapped dirt and extend reuse cycles. Regular rinsing can reduce maintenance time and keep water clearer between replacements. Always inspect seals and ensure proper seating during install.
