These are results from testing of the copper-zinc KDF filter media.
They provide specific results on that test, and serve to indicate the effectiveness of the patented FOAM ADVANTAGE process.
The test does not consider the added carbon, or the optional fluoride filter cartridges or other cartridges with which we combine kdf in our many types of filters.

5.1.2 Chemical: The arithmetic average of the active agent of each test unit shall not exceed the MCL of the U.S. EPA Primary Drinking Water Regulations, or a similar standard established by any U.S. federal regulatory agency for materials not included in the U.S. EPA regulations. No single sample shall exceed the MCL by more than the established analytical error for the method used.
5.2 Chemical Units: Chemical reduction shall be substantiated by tests showing compliance with the minimum requirements specified as follows:
5.2.1 Chemical Reduction: Shall reduce the specified contaminant/s as shown in Table 1.
Complies. See Table 1.

***** NOTE ADDED BY friendsofwater.com. This shows fluoride removal from the SECOND cartridge used in a 2-canister FLUORIDE PLUS FILTER. The first canister, targeting fluoride in particular, will filter fluoride to a much higher degree. In our 2-canister filter, this cartridge removes additional fluoride after it has gone through the first cartridge.
5.4 Working pressure and hydrostatic performance.
18.104.22.168 Complete assemblies shall withstand a hydrostatic pressure equal to 2.4 times the working pressure or 300 psig, whichever is greater, for 15 minutes without leakage of water from the unit.
Complies. When pressurized to 300 psig at 180 degrees F, there was no failure or leakage of the end of 15 minutes at pressure.
5.4.3 Disposable pressure vessels and all replaceable components subject to line pressure shall be constructed for a working pressure of at least 125 psig and shall meet the following requirements: 5.2 Chemical Units: Chemical reduction shall be substantiated by tests showing compliance with the minimum requirements specified as follows:
Complies. See paragraph 22.214.171.124 above.
Burst test, non metallic pressure vessels
Minimum design burst pressure is equal to 4 times the working pressure or 500 psig, whichever is the greater.
Complies. Burst pressure: 933 psig
5.5 Filter media: All finer media which may be subject to plugging shall be supported to withstand for 15 minutes a pressure differential of 75 psig or a pressure differential equal to the maximum pressure drop the product design will permit when installed under a line pressure of 125 psig without breakdown which would permit the passage of untreated water or media into the effluent.
Filter Media Test Input turbidity: 11 TU Effluent turbidity, initial* 0.7 TU Effluent turbidity, 50 % 0.8 TU Requirement: Effluent turgidity to be 1.0 TU or less; Effluent shall contain no media. *The unit was purged prior to test to remove carbon dust.
5.6 Rated pressure drop: In line entire system units shall not have more than a 10 psig initial pres sure drop at the rated service flow. This does not apple if the unit has an integral flow control or orifice. These units shall meet the requirements of 5.7. Rated Pressure Drop Pressure drop: 2.1 psi
5.7 Rated service flow: 1 gpm
5.7.1 The rated service flow shall be as specified by the manufacturer.
Complies. Measured flow 1.32 gpm
