Brondell RF-20 Water Filter Replacement for Under Sink Reverse Osmosis System

The Brondell Circle Under Sink Water Filter (sold separately) features a replacement water filter designed for easy installation, providing great-tasting water for up to 6 months. This sediment and carbon block filter replacement is specifically tailored for the system, delivering a combination of reverse osmosis membrane technology and 3-stage carbon filtration to ensure safer and tastier drinking water.

The carbon-based block filtration helps reduce cloudiness and trap unwanted components, while the reverse osmosis membrane technology further enhances the water quality. The sediment filter reduces rust, sand, and particulates, and the carbon block pre-filter removes VOCs, chlorine, and soluble contaminants. The carbon post-filter then further reduces VOCs, lingering contaminants, and chlorine taste and smell, providing clear benefits.

The replacement filter is designed for simple DIY installation, with a quick and easy twist and seal process. The change indicator lets users know when a new filter is needed, and the purchase includes a replacement battery for the faucet's filter change indicator.

Brondell, the company behind this water filtration system, is dedicated to designing hygiene products that help protect the planet's essential resources. From water-saving showers and air purifiers to bidets that reduce toilet paper and energy use, Brondell is committed to enabling more sustainable living, which feels better already.

This water filter replacement set is Gold Seal Certified by the Water Quality Association (WQA) for the reduction of 64 contaminants, including lead, chlorine, chloramines, industrial chemicals, and cysts. To keep the system running at its best, users are recommended to replace the carbon filter set every 6 months.
