What is it??

I found this in a return air duct. What is it and what does it do? It says something about salt utilization on the label.


It may have been for a chemical heat pump system at one time ( just a thought)

AH i did not look close enough i thought it was water pipes, good eye Vince

To me it is a ultra violet filter for air vent system.Please excuse my technical wording for I have just started really learning about home inspection and the techinicl wording.I could be wrong but to me by the picture Isee ultra violet.
