Brondell RF-20 Filter Replacement for Circle Under Sink – 6 Months

Optimize your Brondell Circle system with the RF-20 replacement

The Brondell RF-20 filter replacement is designed to work with the Circle Under Sink Water Filter (sold separately). When paired with the Circle system, this cartridge supports multiple filtration stages that work together to enhance water clarity and taste for up to six months, depending on usage and water quality. Expect a noticeable difference in how your tap water feels and tastes in daily use, from drinking to cooking.

What’s inside: three filtration stages plus RO

• Sediment filtering helps reduce rust, sand, and particulates that can cloud water.
• Carbon block pre-filter targets VOCs, chlorine, and soluble contaminants for a cleaner baseline.
• Carbon post-filter helps reduce remaining VOCs and lingering chlorine taste and odor, improving overall freshness.

Together with the RO membrane, this replacement aims to improve not only the safety of your water but its sensory qualities as well. Remember, results can vary with source water and household usage, so consider this as a possibility rather than a guarantee.

Simple DIY installation and maintenance

• Twist-and-seal installation makes replacement quick and straightforward for most DIY setups.
• Change indicator signals when it’s time for a new filter, helping you stay on track with maintenance.
• Included battery powers the indicator, so you don’t need new parts separately.

In addition to cleaner water, Brondell emphasizes sustainable design, aiming to help protect essential resources through efficient filtration practices and long-lasting components.

Why consider the RF-20 for your Circle system?

Users often notice improvements in water clarity and taste, especially when water starts with noticeable cloudiness or chlorine flavor. The RF-20 is designed to be a straightforward upgrade path for Circle users who want to maintain a multi-stage filtration approach without sacrificing convenience. It’s a practical option for households seeking better-tasting water for daily use, cooking, and beverages, all without committing to a full system overhaul.
