What is that smell when my furnace starts up for the first time in ten months?

What is the smell which the furnace in my apartment generates when I fire it up for the first time in ten months?

Last night was the first time I used my furnace since March. Upon ignition there was a unique strong (but not strongly unpleasant--it is not pleasant but it isn't really unpleasant) smell. When I woke up this morning the smell was gone although the furnace was running. I am guessing it is the smell of the household dust fraction which is my sloughed skin cells burning up. I suppose I could verify this experimentally, but I was wondering if there is good accessible information out there on the internet or in the metafilter hive mind to what is what with this?

I have always attributed the smell to the dust burning off of the heating element.

Agreed, burning dust (and cobwebs, etc.).

In my house I figure its burning dog hair. I always run it for a day or two then change the filter.

I figure it's dust and cat hair. (I also kind of like the smell.)

Spiders. Poor spiders who invested in the wrong housing development.

You really should take the panels off to see if it is only dust. I do that every year BEFORE turning on the heat. One year it was those ladybug-type things, another year it was millipedes, then camel crickets, then a ratsnake, Probably harmless to breathe, but still...

Mouse poop and pee.

No really you'd be surprised.

Remember to change your filters frequently. Especially of you have pets!

We once fried a bat in our furnace.

But yeah. Filters. You're probably not changing them often enough.
