Berkey PF-2 Fluoride/Arsenic Replacement Water Filters, 2-Pack

Berkey PF-2 Fluoride/Arsenic Replacement Water Filters, 2-Pack

The Berkey water filter fluoride reduction elements work by adding the ability to remove the contaminants listed below. When threaded directly onto the Black Berkey purification elements the fluoride reduction element is an effective way to take control of targeted harmful contaminants in your drinking water. These fluoride water filters work as a post filter to the Black Berkey and are compatible with all Berkey water filter systems.

Effectively reduces the following water contaminants

• Fluoride
• Pre-oxidized Arsenic III and Arsenic V
• MTBE
• Other heavy metal ions
  
  

Filtering Fluoride From Your Drinking Water Controversy 

The Berkey fluoride water filter uses a time-tested method that was developed to reduce fluoride in your drinking water. Berkey developed this filter to address the concerns of the many who find the practice of adding fluoride to drinking water questionable or unacceptable. Fluoride has been deliberately added to many municipal water supplies since the 1950's. This common practice is now becoming more controversial, to say the least. New reports and studies about the harmful effects of adding fluoride to drinking water are emerging. The health and hygiene benefits of applying fluoride directly to the surface of teeth are a well known and seldom disputed. The dispute begins with fluoride that has been added to drinking water only comes in contact with the teeth for a very short amount of time and in a very diluted form. After this contact, the fluoride is then swallowed and the human body is subject to the well known ill effects of the fluoride compound for hours after ingestion. Critics claim that in this age of high fluoride toothpaste that is correctly applied directly to the surface of the tooth, the benefits of fluoride in the water supply are negligible and quite possibly unnecessary. Berkey fluoride water filter allows you to make this decision about your health for yourself by reducing the amount of fluoride in your water by >95%. 

REPLACEMENT:

It is recommended that each set of two Berkey PF-2 fluoride water filters should be replaced after 1,000 gallons (3,785 liters). Example: If you had a Big Berkey system (2-gallon capacity) and you refilled the system 2 times per day, you would be using 4 gallons of water per day. Under these conditions, the PF-2 fluoride water filter elements would last 250 days (1000 gal. divided by 4 = 250) or a little over 8 months. Actual replacement period for the PF-2 fluoride filter is dependent on how much water you would use and the presence of other competing contaminants in the source water. High levels of arsenic, fluoride and certain heavy metals may negatively affect the efficiency and capacity of the PF-2 elements.

Technical Information

Testing was performed with a flow rate of fewer than 11 liters per minute per cu.ft. of the Berkey filtering medium at 20 - 30 parts per million (ppm) of the ion in the solution liquid. Results of < 1ppm of the fluoride ion in the effluent were typical for the filter media (>95% reduction). Under optimum laboratory conditions, effluent concentrations of less than 50 part per billion (ppb) were readily achieved which equates to a >99.75% reduction. 

ARSENIC: Arsenic cations and arsenic oxide anions have unique properties that this Berkey filter product effectively targets.

For maximum removal efficiency, maintain the water being treated between a PH level of 5 and 8. Actual capacity is dependent on the level of contamination of
arsenic, fluoride and other competing heavy metal ions. Unusually high levels of these contaminants may reduce the capacity and efficiency of the elements. 

NOTES: 

1. Do not subject to freezing temperatures, high heat or boil the fluoride water filter elements.
2. Under normal circumstances, the PF-2™ canisters reduce water filtering flow rate of most Berkey filtering systems by 15-20%.
   

Priming The Berkey Fluoride Filters

In order to use your Berkey fluoride filter for the first time, you must prime them. The filtering media contained in the element is very dense and contains dust from the manufacturing process. This dust needs to be rinsed from the media in order for the water to run clear and to break the surface tension of the filtering media. Please follow the instructions below in order to get the best results possible from your Berkey water filtering system.

PF-2 Fluoride filter priming instructions

Caution: When screwing the element onto the Black Berkey filter do not exceed 8 revolutions or the threaded portion of the filter will protrude too far into the fluoride filter and possibly damage the filter.

• With the blue caps in place wash the exterior of each PF-2 fluoride element with water and mild dishwashing soap, then rinse.
• With clean hands, remove both blue caps from each end of both filter elements.
• Place the rubber priming button (tan colored) onto one end of a PF-2 and align the hole of the filter with the hole of the rubber washer.
• Press the priming button up against the sink faucet so that the priming button creates a seal between the faucet and the PF-2 element.
• While holding the priming button against the faucet, turn on the cold water slowly, allowing water to fill the cavity of the filter and discharge from the opposite end. Allow water to flow for at least 30 seconds or until water runs clear whichever is longer

Hint: Place the thumb on top of the faucet to apply pressure, this creates a better seal.

• Turn the Pf-2 filter over and prime the opposite end (reversing the flow of water) repeating steps 3 thru 5 until water runs clear from both directions.
• When you think the filters are flushed long enough, run some of the water that is being flushed through the filter into a clear glass and hold it up to the light to see if all of the cloudiness is gone from the water, if not continue priming until water is clear.
• This filter is now primed and ready to install.

Prime each of the PF-2 elements as described above.
