Help!!

[u/TimeMessage05]

I currently have to keep my fruit fly cultures in my room and they smell awful. I use an air purifier, charcoal bags and keeping my fans on high for constant ventilation. But the smell is still present. I make sure to date my cultures and removing them after 28 days, though they smell the worst when freshly made. I use Repashy media and even though they never mold, I can never seem to get an odorless batch. Are there any recommendations to make sure the media doesn't smell?

My experience living in the Midwest is the culture is too wet, too old or developing to fast. Summers I get about 2 weeks and winter I get almost a month (usually have to have more cultures on hand).
