Berkey PF-2 Fluoride and Arsenic Reduction Elements (Set of 2)

In this review of the Berkey PF-2 Fluoride and Arsenic Reduction Elements, the bottom line is simple: these are targeted replacement filters for Berkey gravity-fed systems for anyone who wants to reduce fluoride and arsenic in household drinking water. They are designed to be used with authentic Black Berkey Elements and attach below them to adsorb fluoride, arsenic(V) and pre-oxidized arsenic(III). For households running a Big Berkey, Berkey Light, Crown, Imperial, Royal or Travel Berkey, the PF-2 set is the specific add-on that addresses residual heavy metals that standard carbon elements do not.

Key Features

• Compatibility: Works with Big Berkey, Berkey Light, Crown Berkey, Imperial Berkey, Royal Berkey and Travel Berkey systems so buyers know they are getting the right replacement parts.
• Targeted removal: Specifically engineered to reduce fluoride, arsenic(V) and pre-oxidized arsenic(III) when used together with Black Berkey Elements, improving safety where those contaminants are present.
• Pair design: Sold as a set of two elements so users can equip both Black Elements in a pair and maintain balanced filtration performance in gravity systems.
• Long lifespan: Recommended replacement after about 1,000 gallons under normal conditions, which makes the PF-2s a medium-term maintenance item for regular household use.
• Simple installation: Attaches to the bottom of Black Berkey Elements and sits in the lower chamber, requiring no tools or plumbing for setup or replacement.

Who It's For

This product suits homeowners, off-grid households, and preparedness-minded users who already own a Berkey gravity-fed system and want verified fluoride and arsenic reduction. It is especially appropriate for those who pair Black Berkey Elements with supplemental media to address specific contaminants that are not fully removed by carbon alone.

It is not for buyers who need a standalone filter cartridge or who do not own a compatible Berkey system, and it is not a substitute for primary filtration in municipal systems with heavy contamination issues that require professional treatment. Users needing faster flow rates or instant filtration should consider alternative systems.

Pros & Cons

Pros

• Reduces fluoride and arsenic when used with Black Berkey Elements, addressing contaminants other elements do not.
• Designed specifically for Berkey gravity systems so fit and function are straightforward.
• Simple to install and requires no plumbing or electricity.

Cons

• Some users report slower water flow when PF-2s are installed, which is an expected tradeoff for added contaminant removal.
• Longevity varies by use; while 1,000 gallons is recommended, real-world life can be shorter under heavy use or poor source water.

Specifications

Our Verdict

The Berkey PF-2 set is a focused and practical upgrade for owners of compatible Berkey gravity systems who need verified fluoride and arsenic reduction. It pairs cleanly with Black Berkey Elements and delivers contaminant reduction that many carbon-only setups lack. Consider the expected slower flow and variable lifespan, but for those prioritizing water quality and simplicity, the PF-2s offer good value as a maintenance item.

Frequently Asked Questions

Do these PF-2s work alone?
No. The PF-2 elements are intended to be used in conjunction with Black Berkey Elements; they attach to the bottom of the Black Elements to adsorb fluoride and arsenic.

How often should I replace them?
Berkey recommends replacing PF-2 elements after about 1,000 gallons under normal conditions, though actual life can vary with source water and usage.

Will they slow water flow?
Yes, adding PF-2 elements can reduce flow rate in gravity systems as they add an additional stage of contaminant removal; this is a common tradeoff for improved removal of fluoride and arsenic.
