The CuZn™ Bath Ball™ hangs on a standard bath tub faucet that has a flow-engage knob on top. They last significantly longer than other brands (15,000 gallons - 300 baths in a 50 gallon tub).
The CuZn™ Bath Ball™ is for people who want a quick, messless way to fill their bath with clean, filtered water. The Bath Ball utilizes the new PowerDisk™ patented FilterFoam™ technology, designed exclusively by CuZn™ for water filter applications. The new PowerDisk™ will eliminate dirt, sediment, odors and chlorine that causes dry, itchy, flaky skin, brittle hair, eye, lung and sinus irritation.
Added PowerDisk™ benefits are your bathtub will stay cleaner longer because the filter reduces lime scale, mold, and mildew deposits and helps to soften your water naturally (without salt!!) leaving your skin supple and smooth and your hair soft, silky and manageable.
On Home Testing of Bath Balls
Chlorine in water may be present in two forms, free and combined. Free chlorine does the hard work of killing bacteria and oxidizing contaminants. When you add chlorine to water, you are actually adding free chlorine. When the free chlorine combines with contaminants, it becomes combined chlorine or chloramines. In water, this form of chlorine has very little sanitizing ability, and no oxidizing ability. Total chlorine is just the sum of both combined chlorine and free chlorine.
CuZn Bath Ball are designed to remove free chlorine (CL) from water. Because of how Copper-Zinc works, OTO (orthotolodine pool testing kits that measure chlorine in water) tests do not give accurate readings. Copper and Zinc ions recombine with the chlorine molecules to produce cupric chloride and zinc chloride. Therefore, any test that measures the CI ion (such as OTO and some DPD tests) will show positive in the presence of cupric chloride and zinc chloride. The test may show positive when testing the bath ball even though the bath ball is working perfectly to remove the harmful chlorine. The DPD #1 Test, which tests only for CI2 is the only way to accurately measure the bath ball's effectiveness.
However, even DPD #1 will not accurately test chlorine's removal from water in the presence of chloramines. Chloramine is produced when a municipality injects both chlorine and ammonia simultaneously into the water supply. This is done to reduce CI2's ability to combine with organic matter in the water and thereby produce potentially harmful trihalomethanes (THMs). Because chloramine has less disinfecting ability than free chlorine, a higher concentration of chlorine in usually used to get the same bacteria kill rate.1
Additionally, the presence of iodine ions in water will magnify the chloramine interference when using the OTO and DPD test methods. Also, oxidized manganese in the water may interfere with the DPD procedure.1,2
To get accurate readings of CL2 levels, an amperometric titration method should be used because it is least likely to reflect interferences.
CuZn's KDF®55 filter removes about 95% of free and combined chlorine; CuZn KDF®85 removes about 75% of free and combined chlorine as a new filter and diminishes in capability as the filter is used, as do all water filters. There is only one accurate water test that is capable of measuring both free and combined chlorine -- DPD#1 Test. Unfortunately, because of the nature of the beast, false readings are common, as described above.
For practical purposes, a person's body will tell him or her when the filtration media is exhausted and is letting chlorine through. Besides one's nose noticing the disagreeable chlorine smell, one's skin and hair will become dry, flaky, and itchy in the presence of chlorine.

Features of the CuZn Bath Ball include:
- The patented FilterFoam® PowerDisk™ is a non-carbon filtration media that's non-toxic and recyclable.
- The compact design is easy to install; just hang it from the tub spout.
- Refillable with a replacement filter.
- PowerDisk™ Filter Media utilizes the new patented FilterFoam® Media Technology, which uses an all natural process that works by catalytic action and the redox (reduction/oxidation) principal of dissimilar metals. These controlled releases of ions are carried into the filtered water where they kill bacteria and provide hostile conditions for algae and fungus growth.
- Flow Rate is 4-5 gpm.
- Dimensions are 4" diameter.
