Two sets of Black Filter’s & Two sets of PF-2 Fluoride Filter’s

Description

The Black Berkey Purification Filters are more powerful than any other gravity filter element currently available. The micro-pores within the cleanable Black Berkey purification filters are so small that viruses and pathogenic bacteria are simply not able to pass through them.

Black Berkey purification filters are so powerful, they can remove red food coloring from water without removing the beneficial minerals your body needs. Virtually no other filter can duplicate this performance.

No need for expensive disposable filters. Black Berkey purification filters are cleanable. When the flow rate decreases simply brush the Black Berkey purification filters with a ScotchBrite^® pad under running water, reinstall and your system is again ready to purify water. Each durable and efficient purification filter will last for up to 3,000 gallons (6,000 gallons per set of two) (11,356 to 22,712 liters) and provide years of efficient water purification.

T he PF-2TM reduction elements are designed for use in conjunction with Black Berkey water purification filters to “adsorb” the following unwanted elements found in drinking water.

• Fluoride
• Arsenic V and pre-oxidized Arsenic III
• Other residual heavy metal ions

TECHNICAL INFORMATION

FLUORIDE: Testing for fluoride was based on 20-30ppm of the ion in the influent aqueous solution at a flow rate of no more than 3 gpm (11 lpm) per cubic foot of media. Results of < 1ppm of the fluoride ion in the effluent were typical for the media (>95% reduction). Under optimum conditions, effluent concentrations of less than 50 ppb were readily achieved (>99.75% reduction).

ARSENIC: This product uniquely targets the entire family of arsenic oxide anions Black Berkey Purification filters Berkey Water Filters as well as the arsenic cations.

REPLACEMENT

Under normal conditions it is recommended that each set of two PF- 2TM elements be replaced after 1,000 gallons (3,785 liters)

(The Royal Berkey^® system is about 3.25 gallons therefore the PF-2TM filters should be replaced after 1,000/3.25 {3,785/12.3l} or 307 refills. If the system is refilled about one time per day, the PF-2TM’s should be replaced after 10 months, if the system is refilled about twice per day, the PF-2TM’s should be replaced about every five months).
