Why You May Need a Humidifier or Dehumidifier
DFW weather can be characterized as humid sub-tropical in the summer. This is due to typical wind patterns which bring humidity from the Gulf of Mexico.
In winter, the weather is described as continental, due to short periods of extreme cold during a full Arctic outbreak. These brutal cold air masses usually originate in Alaska or northern Canada, and can penetrate all the way to the Gulf Coast.
Anyone who has lived in DFW for a while knows, we have periods of time in the summer when the outside humidity level is as much as double the healthy level for inside your home. In the winter, there are periods of time (following a cold front coming into the area) when outdoor humidity can be a small fraction of healthy indoor humidity. The humidity level inside your home should be 30–50% year round.

The humidity level inside your home should be 30–50% year round. Heating the air inside your home dries it out even more.
Health affects of too little humidity in your home:
Effects of Dry Air on the Body
Studies have shown that dry air has four main effects on the human body:
Effects of High Humidity You and Your Home
The most easily noticed effect of humidity over 60% is you feeling hotter than it really is. That’s because more humidity in the air means your body’s natural cooling mechanism cannot function as well as it should.
- Energy bills rise because a home with high humidity needs a lower temperature for comfort.
- Viruses, bacteria, fungi, molds, and mildew thrive on high humidity
- Dust mites proliferate. Dust mites live in carpeting, upholstery, mattresses, bed linens & pillows and other soft fabrics.
- Allergens bloom.
- Mold grows on ceiling,walls and floors, especially near corners where insulation is less.
- Algae grow.
In DFW the climate lends itself having both high humidity (in the summer) and (low humidity in winter).
