crusty boogers and dust+fur from her nose??

hello everyone, I hope everyone is having a warm week. 

I'm coming here to ask about if anyone else's cat had a boogers problem. 

My cat started getting these during the summer; first it was crusty like eye crusts, and when I googled, it didn't seem to be a bad problem. 

Starting fall tho, the content changed a bit. She still gets crusty boogers but on top of that she also gets these dust? it's dark grey not the purple brown crust cats get. 

She usually gets them inside her nostrils, not on the side which is where the crusty stuff accumulates usually. 

These look like a little bunch of really short fur, and I thought she might be getting them because she likes to go around the apartment. But I keep my apartment clean (or at least, I try to) and I honestly can't tell what the problem/cause might be anymore.

No change of environment; same food, same apartment, same cat litter, same cat buddy so no new cat stress...I thought dryness might be a problem so we bought another humidifier and the room goes about 40-50% humidity so I don't think that's the problem...

I just can't figure out what this can be!! did anyone else have a problem like this??

Sorry, I have not personally experienced this problem but just wanted to offer a reply.  Do you think it's possible she is allergic to something in your apartment?  Since it has continued for awhile, i.e. summer through fall, I would suggest calling your vet.  He or she would be able to examine her and determine the best solution.  Good luck!
