The media used in our post filter elements can contain a small amount of harmless process dust or fines, due primarily to assembly, handling and shipping of these elements. For aesthetic reasons, we recommend the Berkey® Post Filter elements be purged on both ends to remove the majority of this process dust, prior to installing […]
If you have used your elements: The Berkey PF-2™ elements can be stored in a refrigerator, short term; but definitely don’t store them in a freezer. To do this, remove the filters from the system, place them into a sealable sandwich bag or container and place the filters in the refrigerator towards the front to […]
Does the post filter media contain some amount of cyanuric acid, or is the media washed using cyanuric acid prior to packaging?
No. The activated alumina in the post filter media is not treated with cyanuric acid, nor does it contain any cyanuric acid in the media. For more information about cyanuric acid, click here.
There is a bubble that forms on top of my Berkey PF-2™, near the area where it attaches to the Black Berkey® Purification element in my system. Does this mean it is not working properly or needs to be tightened more?
The elements can be adjusted by either turning them more revolutions or less. If the elements are screwed on too tight, the screen within the post filter can become damaged. This will not negatively affect the performance of the element. The only purpose for the screen is to keep the media within the element during […]
If NMCL’s recent test results show that the Black Berkey® Purification Elements reduce Fluoride, then why do I need the Berkey PF-2™ Post Filter Elements?
NMCL’s most recent laboratory testing indicates that the Black Berkey® Purification Elements will initially reduce Fluoride up to 99.9%. Typically, carbon-based elements that reduce Fluoride begin to lose that ability rather quickly. This may be the case with Black Berkey® Elements as their efficiency at removing Fluoride likely plays out long before the 3,000-gallon life […]
Water Filter Labs tested for the ability of the most common counter top and gravity fed filters to remove heavy metals such as lead, cadmium, arsenic and mercury as well as elements that have radioactive isotopes such as strontium, cesium, uranium, and aluminum reduction. Click the following link to view the test results: Water Filter […]
We don’t recommend the recycling of the Black Berkey® Purification Elements, PF-2s or PF-4s. The shells of the Berkey® PF-2™ and PF-4™ are made of Polypropylene, which is Recycle Code 5. Uses of Polypro (for short) include catsup bottles, yogurt containers, margarine tubs & medicine bottles. However, there is no recycle code for the Berkey PF™ elements. […]
If Arsenic is removed using Black Berkey® Purification Elements then what is the need for Berkey PF-2™ Elements?
NMCL’s most recent laboratory testing indicates that the Black Berkey® Purification Elements reduce Arsenic up to 99.9%. Typically carbon based elements that reduce Arsenic begin to lose that ability rather quickly. This is likely the case with Black Berkey® Elements, which means that their efficiency at removing Arsenic likely plays out long before the 3,000-gallon […]
The Berkey PF-2™ Element, or fluoride and arsenic reduction elements, work in conjunction with the Black Berkey® Purification Elements to absorb unwanted elements found in drinking water. The Berkey PF-2™ Elements filters out fluoride, arsenic, and other heavy metal ions. The Berkey PF-2™ Element is made of non-leaching Polypropolene *5 and is BPA-free. The Berkey PF-2™ Elements […]
