A portable humidifier is a device that you plug in to the wall and place in the middle of a room. These humidifiers can only control the humidity of one room at a time, and they require frequent maintenance like changing the water and keeping the device clean. When your furnace is cycling and heating air in your home, that air is also humidified by the whole house humidifier.
This means that every room in your home can enjoy humidified air by using a single unit. A whole house humidifier is installed in your ductwork near your furnace, either on the supply or return end. While the humidifier is running, water continuously runs down the humidifier pad, is collected by the rotating drum or is misted into the device, depending on your model. When air from your ducts enters the humidifier, it is exposed to the water inside. Because this type of humidifier has a standing pan of water, you need to be diligent about cleaning it or mold can form.
This is the least expensive type of furnace humidifier. You can install a humidifier on almost any kind of furnace system, even older ones. How Dry is Your Winter Air? Does a Furnace Humidifier Cause Mold? The short answer is no — if you take the basic steps to prevent it. Here are some other important steps to keeping mold in check in your home: Ensure your bathroom has a ventilation fan that works. The humidity from an entire family taking long hot showers can help contribute to mold growth in the bathroom.
If you cook a lot using boiling water, you may want to turn your humidifier off for a while, and ensure you have a range hood that vents to the outdoors.
If your technician suspects you might develop mold in your ductwork, a UV purification system will help eliminate the problem. Getting your ductwork cleaned and sprayed can help. During the winter, we notice things like cracked skin, stuffy noses, sinus problems, and colds. These issues are due to the dry air outside but also from the dry air inside your home. Having a furnace humidifier helps add moisture to the air, which makes your home more comfortable. The moist air can even help your house feel warmer while still burning the same amount of fuel.
Fluctuating levels of humidity in the home are not only harmful to your body, but it also wreaks havoc on your wood finishings. Too much humidity can lead to dry rot and mold.
Furnace humidifiers are installed into your HVAC system, so the air coming from your heating unit is humidified throughout the entire house. A traditional, stand-alone humidifier plugs into a wall outlet and sits on the floor. Stand-alone humidifiers only expels the moist air directly from the vents on the unit. This means that the air around the humidifier has the most moisture, and the further you get from the unit, the dryer the air.
To humidify your home with stand-alone humidifiers, you would have to purchase a unit for nearly every room of your house. Flow-through units, by contrast, have their own fans. Steam humidifiers boil water to create steam that is then distributed along with air from the furnace. Steam is very effective at adding moisture to the air in your home, however, steam furnaces cost more money to buy and operate.
Whole-home humidifiers are governed by built-in humidistats, which measure the humidity of the air and only allow the system to work when the humidity dips below its set point. Why would you need a humidifier on furnace setup in the first place?
There are some great health, comfort and home benefits that come with moist air. This dryness can contribute to dry skin , chapped lips and possibly nose bleeds. Dry air can also trigger sinusitis or asthma flare-ups. Your home reacts to dry air, too. You might see more static electricity, peeling wallpaper and cracking furniture from very dry air.
Wood floors in particular can shrink or even crack, causing unsightly gaps between boards. Regulating humidity levels will keep the wood from shrinking and your floors looking smooth. Adding a furnace humidifier can also lead to less overall energy usage in the home because the furnace may not need to work as hard.
