ROCK RF15 Replacement Filter Cartridge

Your tap adds chemicals. We take them out.

The ROCK RF15 is a high-performance replacement cartridge for under-sink systems compatible with 15UA and 15UB housings. Designed for flexibility, it works with standard cold-water connections to deliver purified water directly from your existing tap, a dedicated drinking faucet, or even a refrigerator line.

Long-lasting value

Each cartridge provides up to 12 months or 19,000 gallons of purified water (based on municipal supply and usage), giving you consistent, reliable performance with fewer replacements.

Advanced multistage filtration

The RF15 combines dense carbon block technology with premium filter media to effectively reduce:

  • PFAS (PFOA/PFOS) and chemical residues

  • Lead and heavy metals

  • Chlorine, taste, odour, and fine particles

  • Sediment and impurities

The result is crisp, clean water that tastes better and inspires confidence in every glass.

Certified safety

Manufactured from BPA-free, lead-free components, the RF15 is independently certified by IAPMO to:

  • NSF/ANSI 372 for material safety

  • NSF/ANSI 42 for chlorine, taste & odour reduction

  • Tested against NSF/ANSI 53 standards for lead reduction

Effortless replacement

With a twist-and-lock design, the RF15 can be replaced in just seconds — no tools, no mess, no downtime.

Bottom line: Reliable, certified, and built to last, the ROCK RF15 delivers everyday purity and long-term peace of mind — all for just pennies a day.
