Research the different types and the advantages/disadvantages of using a humidifier. The Mayo Clinic recommends keeping the inside relative humidity between 30% and 50%. Humidity levels that are too high (or a contaminated humidifier) can cause problems with mold, mildew, dust mites and airborne bacteria. "Cool mist" or ultrasonic humidifiers are the safest, but all humidifiers must be regularly maintained and cleaned.
