How long does male pollen stay viable?

I want to start a new grow in the same room I pollinated my plants. I tried to clean as much as possible but I still see tiny bits of yellow dust from time to time. It's really hard to get rid of. I was wondering if I will run into trouble. Plants will start flowering in about one month. By then, will pollen still be able to pollinate my plants, which I obviously don't want to, or am I fine?

I have already searched for info about this but everyone says a different thing, ranging from "it lasts for 3 days" to "it lasts forever".

Mist the tent with water that will kill the pollen. If stored correctly it will last a long time...

Really depends on conditions, cool and dry it’ll last a while, warm , damp conditions, shorter lifespan. I’d add some Clorox in the spray, it’ll kill the pollen and any mold spores.
