Analysis of tests of Black Berkey® filters
1. Extended tests carried out
Filters Black Berkey® have undergone in -depth tests on a wide spectrum of contaminants, carried out by certified laboratories.
- Heavy metals: Proven reduction> 99 % on arsenic, lead, mercury, aluminum, etc.
- PFAS and perflerated compounds: Reduction> 99.9 % on PFOA, PFOS, PFNA, etc.
- Microbiological pathogens: Reduction> 99.9999 % of bacteria and> 99.997 % of viruses.
- Parasites: Cryptosporidium and Giardia eliminated at> 99.994 %.
- Pesticides and herbicides: Reduction> 99.9 % on more than 75 chemical compounds.
- Radioactivity: Reduction of 95.3 % for BETA emissions and 98.7 % for Alpha emissions.
- Uranium: 97 %reduction.
2. Analysis protocol and volume tested
The tests were carried out according to the standards EPA, NSF/ANSI 42 & 53, and ISO 17025.
- Radioactivity tests: 50 gallons (~ 189 liters) tested.
- PFAS tests: 25 gallons (~ 95 liters) tested.
- Microbiological tests: Simulated extreme conditions, validated test.
- Heavy metal and pesticide tests: Validated filtration on high concentrations.
3. Comparison with other filters
| Criteria | Black Berkey® (made in the USA, 5 secret filtration media) | O'Pure 2 WEPPLOW (made in China) | Coldstream FTO+ (made in the United Kingdom) |
|---|---|---|---|
| Number of contaminants tested | 200+ | ~30 | 200+ |
| Long -term saturation tests | ❌ No (extrapolation at 22,000 l) | ❌ No (tests on a few hundred liters) | ✅ Yes (1,500 l / 6 months) |
| Radioactivity tests | ✅ Yes | ❌ No | ❌ No |
| Tests on pathogens and viruses | ✅ Yes | ✅ Yes (low volume) | ✅ Yes |
| Pfas tests | ✅ Yes | ✅ Yes (without long -lasting validation) | ✅ Yes |
| Strong scientific validation | ✅ Yes (EPA, NSF, ISO 17025) | ❌ Limited tests | ✅ NSF standards |
4. Conclusion
THE Black Berkey® offer a Exceptional filtration On a wide spectrum of contaminants. However, No test was carried out throughout the lifespan announced (22,000 liters). Performance is proven on volumes tested in the laboratory, but longevity is based on extrapolation.
Final verdict: Berkey is one of the most efficient filters on the market, but the announced capacity of 22,000 liters remains an estimate.
Filters Black Berkey are made in the United States and contain a Secret formula incorporating five filtration media. This explains why they are not produced in China, unlike the WEPPOWER filters.
That said, weekend coal filters have good filter properties. Just inquire about the advantages of active filtration coal.
