Indoor Air Quality Tip #4: Control the Humidity
Breathe Easy: Indoor Air Quality Tip #3: Keep a healthy level of humidity. Dust mites and mold love moisture. Keeping humidity around 30%-50% helps keep them and other allergens under control.

An air conditioner also reduces indoor pollen count — another plus for allergy-sufferers.
