Cool mist vaporizer

If this has been going on for more than a few weeks, you might consider other sources of stuffiness, such as food, seasonal or dust allergies. Also consider scented detergent/fabric softener /air freshener intolerance or indoor dampness (mold/mildew) issues. If it turns out to be mold, do not use bleach. Use a gentler product available at Lowe's/Home Depot called Concrobium (spray).
