First guess would be that even with your humidifier it just isn't quite enough. You could always get a hygrometer so you can tell exactly how much humidity they're getting. All in all, your ferns don't look that shabby, and they very well might just be adjusting. Could also try watering them with either distilled water or rain water if that's in your budget because they can be quite sensitive plants. My boston lives in an east facing window in my bathroom and is a happy clam. Sometimes a front starts to brown but new healthy fronds shoot up to replace it and that's just how plants are sometimes. Maybe in a week check and see if your plants are making any new growth.
