The PF-4 attach and are only for use with Super Sterasyl Ceramic Filtration Elementsy. They come in a set of four and install in lower chamber.
PF-4 reduction elements are for absorbing most of the unwanted elements, often found in drinking water. These elements adsorb the following:
PF-4 filters are also designed to adsorb:
- DBCP (Dibromo-chloro-propane)
- THMs (trihalomethanes)
- Herbicides & Pesticides
- Heavy Metal ions
Note: The PF-2 shell is made from safe, non-leaching Polypropylene #5, that is BPA-Free and is used for food items such as ketchup bottles and yogurt containers.
Assemble the water filter as per the water filter assembly instruction. On the underside of the upper chamber locate the stem of each ceramic filter (do not remove the wing nut holding the filter in place). With clean hands, remove blue caps and screw a PF-4 filter onto each filter stem (the blue arrow should point away from upper chamber) giving five full revolutions. Do not screw more than five revolutions as this may damage the internal media screen. When complete, seat upper chamber on top of the lower chamber. Fill upper reservoir. When the lower reservoir is full, discard the first batch of water, which may contain process dust. (Note: when lower chamber is full of water, the PF-4 filters will be immersed).
MTBE testing: The PF-4 exceeds ANSI/NSF Standard 53 requiring Methyl-tertiary-butyl-ether( MTBE) be reduced by at least two thirds from an influent rate (water going in) of 15ppb to an effluent rate (water going out) of less than 5ppb (>95% reduction*).
LEAD testing: Laboratory tests show that when 2000 gallon (7,600 liters) of influent water at a concentration of lead of 150-200 ppb pass through 200 grams of media at a flow rate of 1 gpm (3.8 lpm), the lead level was reduced to less than 1ppb (>99% reduction).
FLUORIDE testing: Testing for fluoride was determined with 20-30ppm of the ion in the influent aqueous solution at a flow rate of no more than 3 gpm (11lpm) 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).
It is recommended that the PF-4 elements, under normal conditions be replaced every six-months. Actual filtering capacity may vary in the presence of other competing contaminants in the source water. High levels of total organic carbons, volatile organic compounds (VOCs) or certain inorganic minerals may reduce the capacity and efficiency of these elements. Note: Boiling these elements will damage these elements and render them ineffective.
MTBE (Methyl-tertiary-butyl-ether) is the most common oxygenated fuel additive used in reformulated gasoline. There is growing problem of MTBE contamination of groundwater in 49 U.S. states. Consuming this water, even small minute traces of MTBE can cause taste and odor problems and can lead to nausea and dizziness. Long-term health effects of MTBE are not well understood, although, initial studies indicate MTBE may cause kidney and liver problems. Removing MTBE from the water we drink is difficult because this pollutant is very soluble and it competes with other organics that bind on the filtering elements. Organic carbon contaminants BTEX and TOC are adsorbed more readily, and MTBE often slips by standard carbon filters, ending up in the filtered water. The PF-4 filter removes MTBE from drinking water using the advanced designed Super Sterasyl ceramic filtration elements. The media within the Super Sterasyl filters, in the top chamber, captures and adsorbs BTEX and TOC's. With these orgnics removed the downstream PF-4, secured as a post filter, will more efficiently remove MTBE.
