The oppositte. Dryer environments reduce humidity. Winter time is lower humidity. Less humidity makes virus more aerosolized. The more wet the air, the less viruses can easily spread. Use humidifiers indoors and HEPA filters to aid in mitigation.

Sure , the air is dry in winter , granted that it doesn't rain (no chance of that here ) ,but that is outside, most people spend most of their time in an inside environment.
Moisture inside could come from people , cooking , hanging your coat up to dry on the rack , inadequate ventilation.
When there is moisture in the air, it has a medium to float around in.
You said yourself that it binds itself to water droplets , it can ride around on the current .
I don't expect anyone to watch lengthy videos against their will , but I've never seen a hairpin turn quite like the "concensus" on the effectiveness of masks, it is quite stunning .

This video emphasizes my earlier statements regarding N95 vs face diapers.
They never pushed proper N95s or better on the public because there was a supply shortage. They needed to ensure they could protect themselves, and then limit access to only those in medical and first responder (ambulatory, fire, police) community.
Governments and agencies acted in their own best interests, not that of their constituents, and policies were political and control based. Ignore what they say and do what you feel appropriate for personal protection.
I'll concede that n95's are more effective than the diapers with the gaping holes vs properly fitted and all the rest, for the sake of civility, cause any talk of covid bullshit makes me blow my lid.
The point is moisture drops are big, and get stuck in an N95 mask.
In dryer air, stuff can float around easier and doesn’t get stuck in the big water drops.
N95 masks are not the same as KN95, or other “masks”like surgical or cloth etc.
Supply chains for N95 support the construction industry mainly, not the world. Mask mandates are a farce, but that doesn’t mean N95 masks don’t work.
Nuance is important.
