result in a leak or drip where the cap and body screw together. That leak is
a safety drip to release water pressure and to prevent breakage. It is also a
signal that the cartridge is past changing time.
Let’s Talk About Recycling
Multipure cannot reuse the media but encourages you to return your used
cartridge for complete recycling to be used in other industrial applications.
We’d much prefer these products get a second life than end up in a landfill.
The small amount of postage it takes to send it back is a contribution to the
welfare of our planet. Please mail or ship the cartridge to:

Testing at Home for Free Chlorine
Chlorine testing using the OTO (standard swimming pool kit) or DPD test
kits may incorrectly show a reading of little or no free chlorine reduction.
The presence of iodine ions in the water will magnify the chloramine
interference with the OTO or DPD procedure. The presence of chloramine
used as a disinfectant in the water supply will also produce erroneous
test results.
When a municipality injects both chlorine and ammonia simultaneously
into the water supply it produces chloramine. Chloramine reduces the
free chlorine’s ability to combine with organic matter in the water that
produces potentially harmful trihalomethanes, THM’s.
Because chloramine has less disinfecting ability than free chlorine, a higher
concentration of chlorine is usually used to get the same bacteria kill rate
(1)The chlorine remaining in the water, after it has combined with any
harmful bacteria, is the free chlorine that the Aquashower removes. No
KDF or carbon shower filter can remove 100% of the free chlorine. To get
accurate readings of free chlorine levels it is better to use quality laboratory
procedures such as the amperometric titration test method. Even under
the best testing methods some amount of chlorine will be indicated.
