Product Description

Product Description

The versatile Big Berkey system is the ideal system for use at home with small or medium sized families, travel, outdoor activities or during unexpected emergencies. This powerful system purifies both treated water and untreated raw water from such sources as remote lakes, streams, stagnant ponds and water supplies in foreign countries, where regulations may be substandard at best. Perfect for everyday use, outdoor activities and a must in hostile environments where electricity, water pressure or treated water may not be available. The Big Berkey system removes pathogenic bacteria, cysts and parasites entirely and extracts harmful chemicals such as herbicides, pesticides, VOCs, organic solvents, radon 222 and trihalomethanes. It also reduces nitrates, nitrites and unhealthy minerals such as lead and mercury. This system is so powerful it can remove food coloring from water without removing the beneficial minerals your body needs. Virtually no other system can duplicate this performance. Constructed of highly polished 304 stainless steel, the system comes complete with four purification elements and utilizes the latest technological advances. This system has a storage capacity of about 2.25 gallons (8.5 liters) and when in use it stands 19.25" in height with a diameter of 8.5". The upper chamber nests within the lower chamber for transport and stands only 13" in height. Configured with four Black Berkey purification elements the system will purify up to 7 Gallons (13.3 liters) per hour.

After reading many reviews on this site as well as prep sites etc. I bought one of these units last summer (on Amazon, from Big Fly Sports) just prior to the arrival of hurricane Irene intended as a safeguard in case of potable water loss/contamination (and because our tap water tastes like algae anyway). Well, I prepped the black filters as per the instructions and gingerly tightened the plastic nuts so that they were secure but without stripping them and filled it up; the water tasted fantastic and I felt good about the investment. There is no o-ring seal, it's a rubber gasket and both the threaded portion of the filter outlet tube and the nut are plastic so you can't really tighten them down much plus the steel in the base of the upper chamber isn't thick enough to keep it from flexing. I performed the red food coloring test and the water came out with a slightly pink tinge to it but considering that the dyed water in the top chamber was dark red, I thought that it was acceptable. We kept the Big Berkey on it's own stand, filled it with water from a pitcher, didn't take it anywhere and it wasn't mishandled. About a month and a half or so later when I was filling it, I noticed that the filters wobbled more than usual and one simply fell over leaving it's base and what appeared to be silicone adhesive behind; turns out the second filter was no longer adhered to it's base either and was simply sitting there held down by gravity. I was under the assumption that this product came from British Berkefeld, known for the performance of their ceramic filters which are used to produce safe drinking water from contaminated sources. After some research online, I found out that Fairey ceramics in the UK produce the filters for BB and Doulton, I then located the UK contacts at British Berkefeld.Read more ›

I searched for the best water purification technique available primarily because I was shocked at the state of our drinking water and I couldn't just go on blindly dumping chemicals into my body. My criterion was to remove all added chemicals from my drinking water including Fluoride and as an Engineer with a scientific background I needed scientific backing.

Note: The usage of Fluoride in our water systems is controversial, but Ninety-seven percent of western Europe has eliminated fluoride from drinking water. goggle "Fluorosis" and "fluoride side effects", read the article on "about dot com" on "fluoride removal". Read the article on "livestrong dot com" on "side effects of fluoride ingestion". I quote, "Fluoride ingestion has been associated with adverse health effects such as IQ deficits in children, depression, weight gain and heart disease. The "Journal of Applied Clinical Pediatrics" reports that "high fluoride intake has a damaging effect on intellectual ability," and human studies from China, India, Iran and Mexico found that elevated levels of fluoride in children resulted in reduced performance and impaired development of intelligence. The U.S. National Research Council has also found that fluoride affects normal endocrine function, which may contribute to hypothyroidism, or reduced activity of the thyroid gland. Hypothyroidism can lead to fatigue, depression, weight gain, hair loss, muscle pains and heart disease.

I started off with on a friends recommendation the Nikken Pi-Mag which i soon rejected because they independent lab results were not available, fluorine was not removed from the water and I could not trust a MLM companies claims' that were not scientifically verifiable.

I decided against distillation, since there are many cons with that process: it produces acidic water (I used to buy distilled water from the store until I started noticing my gums were getting itchy from it), and recaptures chemicals with lower boiling points than water. This was unacceptable to me since California's municipal water sources are heavily chlorinated. It's so nasty, you can smell the chlorine coming out of the taps. I can't stand the taste or smell of it. I decided against reverse osmosis because of its costs and the amount of waste water it produces. After much research, I settled on a gravity based microfilter, and Big Berkey came with lots of recommendations.

So far, after nearly filtering 200 gallons, the Big Berkey is pulling all free chlorine out of the water. Here is a pic that demonstrates:

[...]

The water on the right is tap water mixed with a chlorine/bromine indicator solution. The color indicates that the tap water in Monterey, CA has more chlorine than a healthy swimming pool. YUCK! The water on the right is from the Big Berkey. The indicator solution shows there is no detectable chlorine! SWEET!

My original review was deleted by Amazon. This gross and unjustified censorship is particularly disturbing, especially since my original review received nearly %98 helpful votes (approximately 50 votes). Anyways, since I always save my data...I was able to re-post this information. Please only try to contact me with questions AFTER you have read my ENTIRE review. I have put a lot of time trying to spell everything out here. You will see my email address embedded within this review is you have any SPECIFIC questions that were NOT already addressed. If you are wondering what my motivation is....it is to help people who are in search of clean drinking water. I remember how much of a heartache it was for me doing all of the research. I just want to help, that all.

ORIGINAL REVIEW

Not to be a buzz kill, but I spend DAYS researching these berkey filters. I even tracked down a gentleman who claimed to be one of the heads of the Toxicology Department, Dr. Portier, at LSU. He said that LSU did infact do ONE water sample on the Black Berkey over 8 YEARS ago and that neither he or LSU endorses their product. He also said that while the test did take place, that not Himself or LSU authorized a document to be placed on the internet. He said the reason that he was so quick to call me back is because he has had nearly 20 different inquires in the past 8 years asking about this "so called" lab analysis document that Berkey puts on their website. He also went on to say, that SOMEONE had to of manufactured the "LSU document" because he did not provide ANYONE with that document. So, even if LSU did do a sample, and if everything went alright, then why did New Millennium Concepts have to manufacture a LSU lab analysis report?
