How Do Whole-House Humidifiers Work?

Home air quality and comfort control systems have become wildly popular, with the biggest boom coming in the past ten years or so. Why? Because it has been determined and verified that the air in our homes is actually pretty gross, and rife with all kinds of pollutants and compounds that we don’t want to be breathing! This has spurred a resurgence of products and services like whole-home humidifier systems.

Not familiar with what a whole-home humidifier is, or how it works? Let the indoor air quality experts at Peninsula clue you in!

Whole-Home Humidifier Basics

A standard or room humidifier is a fairly simple appliance overall. It has a water reservoir, a delivery system (usually a spritz system or evaporative moisture panel), and uses electricity to run. Whole-home humidifiers aren’t actually that much different. They’re just implemented in such a way that they can operate on a much larger scale.

The most common way for a whole-home system to be installed is for it to integrate with your existing HVAC systems. The humidifier assembly is installed on either the supply or return side of a forced-air system so that it can monitor the humidity level in home air and add adequate levels of moisture. Moisture is added one of two ways—either by a cool moisture pad or mist delivery. When the furnace or AC runs, part of the air is diverted into the humidifier assembly, processed, and then the air—now moistened—rejoins with the rest of the air in your ducts on down the line.

The humidifier system is maintained pretty much automatically, with a water supply line directly hooked in, so unlike a single room system you don’t typically need to add water to a reservoir. Maintenance generally only involves cleaning out the system on occasion (once every 6-12 months) to get rid of any buildup, and a professional inspection on a yearly basis.

What are the Advantages of a Whole-Home Humidifier?

The advantages come from the fact that, in our homes, humidity levels are typically far too low. This can be because of a dry natural environment, like what you might find out west, or because we depend on HVAC systems. Air conditioners and furnaces both dehumidify as a natural part of their processes, but they don’t regulate this. It’s more of a byproduct of how they work, meaning they never stop doing it! This can result in dry air, which leads to various problems.

A humidifier installation can aid your home by:

  • Controlling and minimizing dust and other common allergens.
  • Aiding respiratory health support
  • Minimizing dry skin, itchy noses and eyes, and other common maladies that come as a result of dry air
  • Protection for dry air sensitive furniture like wood. Things that can crack and warp in dry air
  • Boosting your HVAC efficiency in the winter. Homes in the healthy humidity range naturally feel more comfortable and warmer, helping you minimize furnace use.
