Winterizing the Humidifier

The house humidity has finally dropped to the point where I need to turn on the furnace's Honeywell HE220 humidifier.

First step is to remove the cover by loosening the screw under the cover.

Remove the filter housing.

Remove the top of the housing and discard the metal filter.

The bottom of the assembly will be caked with water deposites that must be scrapped off and cleaned.

Now it is time for the new filter. I bought this filter at Lowes.

Then I reassemble the housing and return it to the humidifier. Put the cover back on.

Now I can turn the humidifier on. This will allow water to drop over the metal filter. I like to put it on the highest setting, 10, and then adjust it over the coming days until the house humidity becomes comfortable.

The final step is to switch the vent from Summer to Winter to divert the air over the filter.

All done for another year!

While I am at it, I use this opportunity to replace the furnace filter and to inspect the hot water tank for leaks.
