A humidifier makes it easier to get through the cold, dry winter months. Proper humidity is needed to keep your respiratory tract and skin from getting too dry. It also prevents wood furniture from drying out.

The Aprilaire 700 Automatic Whole House Humidifier is capable of servicing an area as large as 4200 square feet. That allows you to keep humidity levels in normal ranges in all rooms of your home. That makes it much more convenient than maintaining room humidifiers in each bedroom. The Aprilaire 700 Automatic Whole House Humidifier has a built-in fan that keeps humidity circulating so it spreads evenly and one area does not become too humid while another becomes too dry. This whole house humidifier has received excellent reviews from owners for affordability and function.

The Aprilaire 700 Automatic Whole House Humidifier is very easy to use since it has digital controls and is fully automated. In fact, it looks and works much like a thermostat. The disadvantage to buying the Aprilaire 700 Automatic Whole House Humidifier is that it must be professionally installed because it connects to the wiring in your home. Professional installation costs a couple of hundred dollars and drives up the final cost.

It has a convenient transparent water take so you can see how much water is left in the unit. It also has a demineralization cartridge that keeps the water and mist free from particulate matter. Because of its design, the growth of fungus and viral contaminants is suppressed.
