Thank you so much for this post! I have been struggling with how to remove odors without buying an expensive filtration system.

I've had the fan on in the window of one of my mouse rooms every day, and my boyfriend comes home yelling because of how expensive the heating bill is going to be.

I'm going to put one of these together this weekend!

If it works, I'm going to make one for every room with pets!

Thanks a ton!
