Which One: Whole-House or Portable Humidifier?

Whole-House or Portable HumidifiersThe air is beginning to dry up in the Pacific Northwest now that fall is here. This can adversely affect your breathing if you have allergies. A humidifier inside your home can improve the indoor air and keep allergen levels in check. As a homeowner, should you buy a whole-house humidifier or a portable humidifier?

Whole House or Portable Humidifier: The Pros and Cons

Whole-House Humidifier

A whole-house humidifier is a permanent installation mounted to the home furnace or HVAC system.


  • The humidifier is virtually maintenance-free on the homeowner’s end. The unit auto-adjusts to keep the home at the optimal moisture level. You also don’t have to refill it since it draws water from a cold-water supply line.
  • It’s cost effective. Humidifiers consume very little energy and water. It can also control moisture in the entire home and not just a single room.


  • Every room is at the same moisture level. You don’t have the ability to adjust different settings for individual rooms.

Portable Humidifier


  • Setup is a breeze. Just take it out of the box, plug it in, pour some water, and it’s ready to use.
  • They come in a variety of designs, including animal shapes that make them ideal for a young child’s bedroom.
  • Unique moisture levels are possible for each room.


  • Portable humidifiers are a bit more expensive to operate because the unit uses more power.
  • You have to refill the unit, usually daily, with distilled water.
