Full Answer

The Comfort-Aire unit scores well on ease of using the controls and cleaning the air filters. It has two fan speeds and a timer but operates with more noise than some units. The Danby uses more energy than some units but has an easily removable tank. The DeLonghi weighs less than most other units but has a more limited range for dehumidification, between 30 and 50 percent. The Frigidaire unit makes minimal noise and can achieve a humidity range between 35 and 85 percent.

High indoor humidity can cause mold. It also causes people to be uncomfortable and exacerbates a number of health conditions, such as allergies and respiratory-tract infections. Studies have shown that bacteria and mites die off at lower humidity, according to the National Institutes of Health. High humidity can cause toxic chemicals to seep into the air at higher rates. Most of the negative health effects associated with humidity occur least often in humidity levels between 40 and 60 percent.
