Yesterday, we wrote about insufficient humidity levels in our home and winter had just begun.
The first thing we checked was to see if the water was flowing into and out of the flow through humidifier. It was not. I found the on / off valve and turned the water on. I still have no idea who or how that valve had been turned off.
Next, I then checked that the damper from the flow through humidifier into the furnace was set at the winter setting so humidified air would actually go into the furnace. You can see the knob on the left of the humidifier unit in the picture below.
I also adjusted the humidity setting for the flow through unit by way of the humidity gauge which is placed in our case on the cold air return directly above the humidifier, again in the above picture.
Now, knowing that the humidity level in our home was less than desired the past couple of years, I wondered what more I could do.
One of the things I noticed once the water had started flowing through the pad inside the flow through humidifier was that it was still pretty much dry. When we moved into our current house two years ago I had asked around about this and was told that, no, the pads inside flow through humidifiers are never wet all over like a sponge; instead only parts on the inside of the pad are wet as the water passes.
So, to me, if I could get the pad to hold more water, then more humidified air would be generated and up would go the humidity level in our home.
So, one approach, would be to use a simply spray device to spray water on the pad, manually, every now and again.
Sure, this would be a painfully manual approach which would need to be done constantly. However, when I am not travelling I work at home, so this could help us in place of spending more money on buying multiple humidifier units and place them throughout out home. In this latter case, not only would I have to be spending money to make the purchase but I would also have to manually re-fill them likely daily. So, using a manual water sprayer, yes, in an old and thoroughly cleaned former Windex spray bottle , would not be so bad.
So, I tried this over the weekend to see if it did make a difference and if I would be able to remember to actually do this. Every so often, I sprayed sufficient water from the bottle onto the pad inside the flow through humidifier sufficient so the side of the pad facing the opening in the unit was wet.
But, this is not the end of what we tried to do in an effort to increase the humidity level in our home. There was one more thing I wanted to check.
This is where we pick things up tomorrow on this one of many home maintenance tips which may work for you.

Good blog. I have a steam humidifier. However it runs much more than the furnace. This is because of dry air infiltration. My house has about 7 to 8 air changes per day as measured at 25 PA blower test. I am now trying to reduce to half that by sealing up leaks. Such as were electrical lines enter the wall from the crawl space. Doing away with the attic door and replacing it with ships ladder from a lower attic section and sealing wall leaks to the 2nd floor from the attic and replacing the ductwork in the crawl space. I live in York county SC and I don’t see how this duct work passed inspection. Probably never inspected.

Hi Joe,
Thanks very much.
Here the summary article on our efforts to seal air leaks in our home in case the articles therein help and / or give you ideas on where to look / how we did it:

Replacing duct work in the crawl space? Wow, that can be a nasty and frustrating task. Good luck to you.
