A Whole-House Humidifier Will Help You Deal With Dry Air Throughout Your Home

When it’s too cold in your home, you turn on the heating. When it’s too warm, you turn on the cooling. So when the air is excessively dry, why don’t you turn on the humidifying? Just like being too cold or too hot, being too dry is uncomfortable. A dry throat or itchy skin is preferably avoided. Furthermore, excess dryness may also lead to damage to your home or your furniture. What’s the answer to excessive dryness? Installing one of the best whole-house humidifiers.

Unlike your average portable humidifier or single-room device, the best whole-house humidifiers are built with greater coverage in mind. To achieve this goal, these devices are usually larger in size or capable of being connected to your home’s forced-air furnace system. Here are some of the benefits of each device style:

Freestanding Humidifiers

  • Temporary – Freestanding units are a great temporary option. If your local climate is only dry some of the year, meaning humidifying is only necessary for a few months, you may prefer a device you can bring out when it’s required and store it the rest of the time.
  • Portability – While these devices are capable of humidifying large areas, if you only want to cover part of your home or a certain number of rooms, these devices are ideal. Most include built-in wheels for greater mobility, allowing you to move them freely and create areas of improved humidity, without having to commit to every room in your home.
  • Price – While a slight difference, the average cost of a freestanding device is lower than an in-furnace device. If you’re not ready to fully commit to full-time humidifying, these devices are a good way to go.

In-Furnace Humidifiers

  • Coverage – By connecting to your house-wide air-handling system, your humid air reaches every corner of your home. This may be preferable over freestanding units, where freedom of air movement can be blocked or limited by closed doors.
  • No Refilling – Unlike freestanding units, in-furnace devices connect to a power and water supply, meaning you don’t have to plug them in or refill the water tank every time you want to use it. 
  • Hidden – From a purely aesthetic standpoint, in-furnace devices are located near your furnace. This means they are out of the way and aren’t taking up space or creating an eyesore in your living room, hallway or other open space.

Below you’ll find nine of the best whole-house humidifiers. We’ve included both free-standing and in-furnace devices, allowing you to choose the right style for your home.
