Oh well.
The air smells sweet, and it's cool.
All is well.
It's been a while on this one and it's a great thread so how about a refresh? Also, I'm looking for more clarification.

I read in another thread about the can of GM spray product that puts an antimicrobial coating on the evaporator fins. Hook, in your expert opinion, is that a value added step when you're adding the cabin air filters or does the addition of filters in itself fix the musty odor problem?

I probably wouldn't even ask but that canned excellence crap from GM is not really cheap. I'd do it in a heartbeat if I thought it would help but if it's a waste of time and money, then why do it?

I'm pretty pumped up to perform this mod as it's not just an odor for me. I nearly live in my truck for a week at a time and this time of year I start coughing and even getting a sore throat after a few hours each day. Those symptoms went away last winter but now they're back at the same time as the musty A/C odors.
