Alexapure Pro Overview
The Alexapure Pro is a stainless steel gravity water filter that competes directly with the Big Berkey. At a significantly lower price point ($200-250 vs $350-400), it promises similar contaminant removal, fluoride reduction without add-ons, and a 5,000-gallon filter life.
Bottom line: The Alexapure Pro offers the best value in gravity filtration. It matches Berkey's core performance at roughly 60% of the price, with fluoride removal included. Build quality is slightly less refined, but filtration performance is comparable.

Like Berkey, Alexapure does not have NSF certification. Results come from independent lab testing commissioned by the manufacturer. Testing appears legitimate but lacks the third-party standardization of NSF.
Alexapure Pro vs Big Berkey
| Feature | Alexapure Pro | Big Berkey (2 elements) |
| Price | $200-250 | $350-400 |
| Capacity | 2.25 gal | 2.25 gal |
| Filter Life | 5,000 gal (1 element) | 6,000 gal per element |
| Total Capacity (max) | 20,000 gal (4 elements) | 24,000 gal (4 elements) |
| Fluoride Removal | Built-in (~97%) | Requires PF-2 add-on (~95%) |
| Flow Rate | ~3 gal/hr (1 element) | ~3.5 gal/hr (2 elements) |
| Construction | 304 stainless | 304 stainless |
| Spigot Quality | Standard plastic | Higher quality |
| Brand Recognition | Growing | Established leader |
The Alexapure Pro saves $100-150 upfront and includes fluoride removal. The Big Berkey offers longer per-element life and higher build quality. For value-conscious buyers, Alexapure wins. For maximum refinement and brand reputation, Berkey remains the standard.

Frequently Asked Questions
Is Alexapure as good as Berkey?For contaminant removal, yes — performance is comparable. For build quality and brand longevity, Berkey has the edge. Alexapure is the better value; Berkey is the safer long-term bet.
Does Alexapure really remove fluoride?Independent testing shows up to 97% fluoride reduction. This is built into the filter element — no add-on required, unlike Berkey.
Can I use Alexapure elements in a Berkey system?No. The filter elements are not cross-compatible. Each uses proprietary threading and sizing.
How do I clean Alexapure elements?Same as Berkey — gently scrub the ceramic surface with a clean scouring pad under running water every 3-6 months or when flow rate decreases. Do not use soap on the ceramic.
