Congratulations on dumping the caffeine
smell- I don't care for the smell but it's not the worst. The prob is that acid reflux you were getting in your throat, I was getting that in my nostrils. It was painful and you couldn't smell anything else.
In a "clean" house (no shedding pets, no smoking, no wood burning, no excess cooking grease, etc.) an AC or furnace filter will still get dirt but it tends to be whitish-gray color.
His was BROWN, coffee brown. It was near the kitchen on the ceiling and it wasn't a big house either.
If you look under kitchen cabinets or shelves where people have operated a coffee maker set back on the counter, you're likely to see the remnants of coffee steam staining on the underside. That's assuming they haven't cleaned that area. You can also feel it. It's gunky.
If you go to a place like Habitat for humanity and look at used kitchen cabinets you're likely to see where a cabinet was exposed to that.
The whole interaction with him was just kind of funny because he was like a 5 year old reverting to tantrum mode. I tried to be so calm and patient. I wanted to get along. He just literally started flopping around on the couch, changing position and sitting with his back toward me. Maybe he'd had that conversation with someone else as well. lol. I just slowly backed away and said I was going to have to move asap. But I wished him well. I treated him fair.
What else was I to do? It was my health. Even though i had my own room, the air conditioning ducts went throughout the house. It was a nice gated 55+ community too.
