Propur Overview
Propur manufactures stainless steel gravity water filters that compete directly with Berkey and Alexapure. Their standout feature is the ProOne G2.0 all-in-one filter element — it removes fluoride, bacteria, cysts, chemicals, and heavy metals in a single cartridge without requiring add-on filters.
Bottom line: Propur offers the most convenient fluoride removal in gravity filtration. The ProOne G2.0 element handles everything in one cartridge — no separate PF-2 style add-ons needed. Slightly shorter filter life than Berkey, but the all-in-one convenience is worth it for many users.

Propur's shorter filter life (2,400 vs 5,000-6,000 gallons) is the trade-off for all-in-one fluoride removal. If fluoride is your main concern, Propur and Alexapure are better values than Berkey + PF-2. For maximum total capacity, Berkey wins.
