DUMB AIR is simple. Bad air makes people tired, foggy, and slower. It's mostly CO2, it's everywhere we gather indoors, and almost nobody measures it. So we do. We measure it, we name it, and we help people get it fixed, at work, at home, at school.
This is open and free. No product to sell you. The scale, the guides, the templates, all of it stays free. If a monitor link ever earns us a few cents, we'll say so, and it goes toward keeping this running. That's it. This isn't a startup chasing your money. It's a thing I believe in.
I'm an engineer, and I'm the person who opens every window. I've carried a CO2 monitor for years, and I got tired of arguing with a feeling when I could just show people the number. Once you see it, you can't unsee it. This is me being loud about it instead of quiet.
Get the toolkit, the monitor guide, and new dumb-air callouts. No spam. Just fresh air.
Open a window. Don't breathe dumb. — Gustav
