A humidifier has proven to be a great addition to households looking for ways to improve their indoor air quality. Humidifiers introduce moisture into the air so that humidity levels stay between 30-50% inside the home. A humidifier is a good idea because it stops the spread of germs between family members and can help shorten the duration of an illness overall. Some of the other benefits include alleviating dry skin, reducing snoring, and even helping grow healthier indoor house plants. Keeping the air more moist can relieve allergy and asthma symptoms and make your household more comfortable overall.
