one of those fluffy yellow dusters with the red thread around the outside, elastic band, as good as anything you'll buy for $20.
Back in the late 80s/early 90s I ran an electronic repair workshop, also sold a few bits like microphones, cables, mixers, lots of stage sound and light related stuff. I managed to sell hundreds of people a yellow duster instead of a proper mic screen on the basis that if it didn't work they could come back and get the "real thing". We only ever had 2 back. You may need "the real thing" if you're outside in gusting wind but 2 layers of yellow duster is usually adequate for fan and breath noise. Just don't pull it too tight over the mic head or it won't work so good

This is what you are looking for: https://mymic.rycote.com/producttypes/lavalier-windjammer/
Expensive though.
You can also use a little piece of fake fur, make sure you can breathe easily through the backing material holding the hairs. If it breathes it is more or less acoustically transparant.

They sell those spongy microphone wind covers in three-packs at Fry's Electronics and at Guitar Center, they're in the aisle with the DJ equipment. Also, if you recored about 20 seconds of "room noise," you can use a VST noise reduction filter to remove it in post-production. Audacity has a built-in VST noise reduction filter, for example.
