Berkey Fluoride Filter – For Pure Drinking Water

A Berkey fluoride filter is the PF-2 post-filter that hangs under the main elements and reduces fluoride in city tap water.

Product: Berkey PF-2.

How It Works

Install PF-2s on the stems of the main gravity elements. Water hits the Black or Phoenix elements first, then the PF-2 media. Fluoride reduction is a chemical claim, not a germ claim.

Fluoride is added by many utilities. Whether you want it reduced is a personal choice. One overview: fluoride discussion.

What PF-2 Is For

Fluoride and pre-oxidized arsenic in tap water, plus other metals the media is tested for. Replace about every 1,000 gallons per pair or about six months in a busy home. Example math for a Big Berkey that turns two gallons twice a day is roughly 250 days.

Pros

• Reduces fluoride
• Long rated life vs cheap pitcher cartridges
• Little change in taste
• No electricity

Cons

• Plastic housings
• First install takes a few minutes

Other Notes

Main Berkey elements handle chlorine, many VOCs, and metals. PF-2 is the fluoride add-on. Gravity only. Pack it for hotel or RV taps that are municipally treated. Do not use it on pond, lake, or other untreated water.

Official main-element replacements: Phoenix filters.

Customer Tests

Home fluoride meters are informal. They are not a substitute for a lab sheet. If you publish numbers, label them as one household’s meter reading.

Final Thoughts

If your city adds fluoride and you want it lower, PF-2 is the Berkey add-on built for that. Use it on treated tap water.
