Winter may turn your yard into a winter wonderland in some areas but the cold weather can also make it unbearable to stay inside your home – Why is this?

When the weather turns colder, the humidity in the air lowers. This is especially true in your home if you are running a heater because the heated air is very dry and will replace the humid air in the home with dry air.

⇒ To fix this problem, you will NEED the best whole house humidifier to make sure your house has enough moisture to be comfortable!

  • Expenses are difficult to predict as your usage may vary too much.


What do you need to look for when you’re choosing the best whole house humidifier? There are a few key things to pay attention to before you make any purchases.


Capacity of the humidifier deals with roughly how much water the system uses daily. Not all systems are built to process the same amount of water into humidity, so you will want to make sure you are getting a unit that will work well for the size of your home.

Houses of varying sizes need different systems. Most humidifier systems are built for a specific size range and will not work well for anything larger or will work too well for smaller homes. Getting the right capacity can make a huge difference in maintaining the ideal humidity levels of 30 – 60% relative humidity.

These are the ideal capacities ranges based on your home size:

Th di

There are many ways in which a whole house humidifying system can operate. Each type hooks up a little differently and produces the humidity differently. It is up to you which system you want to purchase based on how they work, which utilities they use the most and how expensive the systems are. These are the three main types of whole house humidifier systems:

>> Drum

A drum system is installed on the cold air return line. The way it works is by using a motorized belt to lift water out of a drum of water. As the water evaporates and air passes over the water on the belt the air will become more humid. This humid air is then dispersed through the normal heating system around the house.

Drums have the advantage of simple and cheap installation. Unfortunately, they require more frequent maintenance because of the need to have a consistently filled water drum for the system to work completely. The drum not only needs to be refilled but the issue is that mold and bacteria can build up in the standing water over time. To prevent this from happening you must clean the drum frequently. Often the belt must also be replaced frequently as it wears out quickly.

>> Flow-Through

These systems can be attached either to the return or supply lines of your current ventilation system. They do not need an electrical connection but will require a connection to the water line in your home. A flow-through system uses a filter with a constant fresh water drip running through it. Air is blown through the filter and helps to evaporate the purified water. The air then picks up the water vapors and blows the humid air out of the vents.

Flow-through systems are also fairly simple to install and they have the advantage of not needing an electrical connection. They do tend to use a lot of water as the drip is always fresh water and never re-used. While this cuts down on the threat of mold, it also makes your water bill go up during usage. The filter only has to be changed periodically.

>> Steam

Steam systems are said to be the most effective whole house humidifying systems. They are a little more difficult to install and will require connections to both your electrical wiring and your water line. The systems work by producing actual steam vapor into the air in the ventilation ducts rather than letting the water evaporate on its own. The steam is picked up by the passing air and dispersed through the home.

You can choose between hot or cold steam systems that have slightly different steaming methods. As this system creates the humidity directly, you will have better control over what level of humidity it produces in your home. Maintenance is usually easy as the risk of mold will be low with this type of system.


Some whole house humidifiers have features to make them more convenient for you such as a built in humidistat. This device helps you to know what the current levels of humidity are within your home and allows you to adjust them at will. Smart humidistat controls will automatically start the humidifying process if levels drop below a certain point and will stop the process when they get close to an upper limit.


How straightforward an installation do you want? The simpler the installation is, the less money it will cost for professional installation. If you’re handy at doing installations yourself you can try any type although the simpler installations might be best for those without much experience.

A drum humidifier system offers the easiest hook-up in most homes. The flow-through is a little more difficult but is still fairly simple. Steam systems are the most complex and do require more work to install than the other types.




  • Each system has its own instructions which should be present when you buy the system or else explained to you by a HVAC knowledgeable serviceman. If you want to do the installation on your own it is advisable to search for a step-by-step manual for installing the specific system you are buying as each one has its own special requirements.
  • Using a whole house humidifier system is usually very straightforward. In most cases there is either a manual adjustment for when the system should be running, a timer system or an automatic system. It is all based on what the current levels of humidity are in your house versus the desired levels of relative humidity.
  • Maintaining a whole house humidifier varies between systems types. Drum systems must be emptied and cleaned out frequently to avoid issues with mold and bacteria growth in the standing water drum. They also need replacement belts periodically. Flow through systems need to have semi-regular filter replacements to avoid mold issues in the ventilation. Steam systems don’t require much maintenance, but will need to be cleaned occasionally to avoid mold growth as well.
