View Full Version : mineral deposit on evaporator
06-14-2005, 03:50 PM
I have a unit with an in-duct mist humidifier that is leaving deposits on the evaporator coil. Is this something that is addressed with better filtering or is it a problem that can be caused by improper installation?

Regarding your previous post:
“I have a unit with an in-duct mist humidifier that is leaving deposits on the evaporator coil.”
I would be surprise to find no deposits with a typical mist humidifier.
“Is this something that is addressed with better filtering or is it a problem that can be caused by improper installation?”
This is a typical installation and deposits are but a fact of life under the above conditions. Now if you decide you would like to eliminate the deposits left by the mist humidifier, then that is easy, just remove all the minerals and particulate matter from the water first.
This is where you might consider either an osmoses or DI system. The osmoses system is more economical, but the results are not as good as the more expensive DI bed system.
So, you have a choice; spend your money on good filtration, great filtration, or just plain old fashioned elbow grease…it’s your call friend.

Is this contraption you speak of installed before or after the evaporator in the airstream?

Thanks for your reply John.
jacobperkins, it is immediately before the evaporator.
