Filterlogic NSF/ANSI 372 Certified Water Filter Replacement for Berkey BB9-2 & PF-2 – Combo Pack

Overview

Meet the Filterlogic NSF/ANSI 372 certified replacement filters designed for Berkey BB9-2 Black Filters and PF-2 Fluoride Filters. This standalone combo pack is built for independence and compatibility across Berkey gravity systems, including Travel, BIG, Royal, Imperial, Light, and Crown models. Note that Filterlogic is an independent brand and is not sponsored by Berkey.

Certified Safety and Materials

• NSF/ANSI 372 certified for safe materials and trustworthy filtration.
• Lead-free and BPA-free housing keeps the exterior components clean and durable.
• Pre-use flush recommended: black carbon filter for 1 minute and fluoride filter for 20 seconds when connected to a faucet; if the faucet isn’t fully compatible, a splash may occur but will not affect performance.

Filtration Performance

• The BB9-2 black filter uses natural coconut activated carbon block to achieve high adsorption of chlorine and related compounds, helping maintain clean-tasting water.
• The PF-2 fluoride filter has been upgraded to combine granular activated carbon with activated alumina media, substantially improving water flavor and balance.

Longevity and Maintenance

• For best performance, replace the black BB9-2 filter every 6,000 gallons per pair and the PF-2 fluoride filter every 1,000 gallons per pair. Actual life varies with water conditions.
• Note: total dissolved solids (TDS) levels do not fully predict water quality, and these filters do not lower TDS in a guaranteed way.

How It Works and Real-Life Use

In everyday use, you’ll notice fresher-tasting water when the upgraded media engage taste-affecting compounds. The coconut carbon block targets chlorine and related odors, while the fluoride media mitigates mineral flavors without altering essential minerals. This combination is particularly appealing to households seeking a practical, maintenance-conscious filtration solution.

Real-life scenarios include long-term home use with Berkey gravity systems, travel setups that demand compatible, independent filtration options, and households aiming for a consistent filtration experience across different Berkey models.

Installation Tips

• Follow the flush instructions before first use to prime each filter correctly.
• If your faucet is not fully compatible, brief splashing may occur during flushing; this does not affect the filter’s performance.
