Berkey © - When is it from NSF standard and Berkey © filters
What is NSF standard, what is it for? And do Berkey © filters respect the standards of this standard?
Definition
This is a standard that guarantees that the product subject to it complies with certain safety and public health standards.
In a more specific way, concerning water filters, they must meet certain criteria:
• The filtration system must be able to reduce certain contaminants, the list of which must be provided by the manufacturer,
• The filtration system has a coherent structure and does not add harmful substances in filtered water,
• The advertising and documentation associated with the product contains only real information and which cannot be confused,
• The place of production is subject to NSF control and each model must be tested.
NSF/ANSI standards 42 & 53
These are the standards that specifically apply to water filters that claim NSF standard. Here is a synthesis.
Standard NSF/ANSI 42
• Organoleptic effects: filters must reduce contaminants that are unrelated to health: (chlorine, taste and odor, particles) likely to be present in drinking water of public or private origin,
• This standard uses charcoal filtration in particular,
• There are different classification in this standard depending on the rate of elimination of chlorine or particles. The best ranking concerning chlorine claims a reduction to more than 75 % (class I). The best classification concerning the reduction of particles corresponds to an 85 % reduction in particles between 1 and 5 microns (class I).
Standard NSF/ANSI 53
• concerns the reduction of contaminants relating to health. These include cryptosporidium, giardia, lead, volatile organic compounds (VOC), MTBE (methylteriobutyl ether) capable of being present in drinking or private drinking water,
• This standard uses charcoal filtration in particular,
• To comply with this standard, the system must effectively reduce the lead content,
• The system must be able to reduce up to 99.95% the concentration of cytes such as cryptosporidium, giardia, toxoplasma and starto,
• The standard makes it possible to certify that the product effectively reduces VOCs such as: Alachlore, atrazine, benzene, carbofuran, chlorobenzene, 2,4-d, icthlorobenzene, p-dicklorobenzene, the Lindane etc.
And the Berkey © filters in all of this?
The manufacturer Berkey © has chosen not to subscribe to this standard. This does not mean that the Black Berkey © filters that equip Berkey © filtration systems do not respect it. On the contrary, the tests carried out on the NSF42/53 standards show that the Black Berkey® elements largely exceed the standards of this standard.
Why this choice ?
Berkey © systems are not just water filters intended to filter tap water, but effective purifiers on untreated water. Their deployment by NGOs or the army in emergencies proves it ...
- Regarding Standard 42: It would just be unnecessary to have it certified so the capacity of filters exceed it ... The strictest of the standard 42 classes of the NSF standard recommends a reduction of 75 % of chlorine. Black Berkey © filters © get a score of 99.9 % on chloramines, 99.9 % on free chlorine, 99.6 % on chlorides and 99.9 % on fluorides ...
Same observation on the particles. The strictest standard of this standard recommends an 85 % reduction in particles between 1 and 5 microns. Black Berkey © filters operate on a scale of 24 to 26 nanometers, which is equivalent to 0.024 microns…
- Regarding Standard 53: Black Berkey © filters eliminate 99.9 % of lead and respond perfectly and even far exceed what is recommended by the NSF standard. Regarding the cryptosporidium, the Black Berkey © filters have a score of 99.997 %, 99.99 % on the Giardia, 99.8 % on the leptospirosis ... Again, the results speak for themselves. Ditto for VOCs: 99.9 % on Alachlore, Atrazine, Benzene and its derivatives, the Liandane but also dozens of others.
In addition, Black Berkey © filters are also effective in viruses, bacteria, pharmaceutical residues, petroleum products, dozens of pesticides, herbicides and heavy metals, alpha and gamma radiation and uranium.
Finally, it should be noted that the Black Berkey elements are not simple water filters but are water purifiers. The NSF standard requires elements of "purifying" types to filter their nominal contaminated water capacity through the filter before any measurement of measurements. Clearly, the NSF standard would require filtering 45400 liters of water to raise the test results, where the lifespan of the Black Berkey® was established at 22700 liters, which has absolutely no sense.
This means that Berkey should announce a life of Black Berkey® reduced by half, just to obtain NSF certification when they have the capacity to purify double.
This is insane and that explains why there is no gravity water purifier to the NSF standard, and it makes it all the more unique the Berkey® gravity filter in the purifier market.
The results of the tests carried out on the Black Berkey® filter elements are therefore very far above the recommendation of the NSF standard.
All of the tests published by Berkey © were carried out by accredited and independent laboratories and were carried out following standards 42 and 53.
Asking for the accreditation of this standard is therefore not only perfectly useless because it would be completely reducing the true capacity of the systems equipped with Black Berkey® and would generate estimated costs approximately $ 1 million for all the pollutants that Berkey has been tested.
It is for all these reasons that Berkey® did not consider it necessary to certify its systems by the NSF standard and not because they would not satisfy the expected results. Black Berkey® filters are much more efficient than other simple NSF labeled water filters, have a significantly higher lifespan and ultimately, a cost in the ultra -economical liter.
