The set up:

I enclosed the part of the garage to make an office/man cave. I had a Mr. Slim installed to control the temperature. The space is 10' X 20'. No carpet. There are three desks, three chairs, a couch, an upright freezer, 7 computers, and a few guns. Your basic geek-ed out man cave. ;)

The issue:

There is an odd lingering smell.

The Smell:

It's a Sweet + foot smell. I don't know how else to describe it. It's not repulsive, but not great. It first hits you when you enter the room. My carpet cleaning friend said it's not something he has come across before.

I asked my wife to describe the smell. She said "Stale locker room with a hint of chocolate chip cookie."

What I have already done:

I fist suspected Mr. Slim. I checked the drainage line and found that is was not draining correctly. I ran a new pipe. Then let the humidifier run for a day and made sure there was a nice flow of water at the end of the pipe and no water in the collection tray. There isn't any bulging paint or warped baseboards under Mr. Slim.

I used a can of Evap Foam no rinse cleaner on the Mr. Slim coil. So I don't think Mr. Slim is the issue.

I found a Kenmore 85500 Air Purifier and have been letting it run with an new filter for about 2 weeks. The smell is less intense but still there.

I had all the same furniture in the old man cave and didn't have the smell.

The question:

Any other ideas on ridding my man cave of this smell?

    Can you describe the smell better than "odd"? Chemical, musty, mousy, ...?

  • @Mike Perry~ I was actually just looking at something like this: condar.com/asv.html and Air King AK300LS on a timer to run for a few hours in the night.

Comment by "NitroxDM": I was actually just looking at something like this, "Condar ASV", and Air King AK300LS on a timer to run for a few hours in the night.

I honestly don't know anything about those products, as I have no first-hand experience with them, but they look like they would work well in bringing in clean air & removing stale air...

I do know from using trickle vents in the UK and from their wide use in the domestic building market there in the UK:

  • They are cheap.

  • Easy to install, definitely a DIY project.

  • Do a surprisingly good job at providing natural "background" ventilation to an indoor room (space).

    I have been keeping the door and window open for a few hours in the morning. That seams to help. I ordered up a the vent we will see what happens from there.

  • Life happened and I have yet to install the vent. I'll update this question again. ;)

  • I installed the vents. It just sucks sand into the room. And it still has the smell. When I find the cause/fix I'll be sure to post it here.

Is the garage floor concrete? The odor may be coming from something (antifreeze, other vehicle fluids, etc) spilled on the floor in the past. Sealing the floor may help.

  • I like the concept. It's new construction and I inclosed the room before any cars where ever parked here. However... it was in the winter when when I stained the sealed the floor. Maybe the heat (it's 110+ F around here most days) is doing something to the concrete. The same smell exists in the rest of the garage but not as strong I assumed it was just flowing from the cave. Maybe the concrete is off gassing in the heat?
