Not a device suggestion but a debugging suggestion, have you moved a second floor alarm with a ground floor alarm?
If not, move only 1 alarm and see if that goes off

It's a good idea, but at this point I'm too frustrated to wait a few months to see if the moved alarm does or does not go off. And then I'd have to figure out what's different and how to fix it.
Right now I'd rather spend some money and get smarter alarms, if they're available.
You are not supposed to have smoke alarms in the bathroom or just outside of a shower bathroom for this reason actually. Also not in the kitchen. A heat detector is recommended for the kitchen.
I had alarms that would go off specifically in the winter in our stair tower because it was a 200 year old house that was renovated badly with no insulation.
Even my Fibaro smart CO alarm got bugged and drained its entire battery in 2 days because it was in a 5-10C environment (within their specs, but they simply lie on the specs).
From my experience, any life saving device simply can't handle moderately cold temperatures at all, which is honestly extremely ridiculous to me and very dangerous.
Your problem, if dust related would likely be because you are using optical alarms which are easily susceptible to dust. If that is the case, you could try replacing those with ionization alarms on the 2nd floor. Ionization detects flaming fires better and optical detects very smokey fires better.
OP here, I ended up purchasing one USI MI106S, which advertises the following:
Which sounds like what I'm looking for. I'll try some informal tests on it before I buy more.
