Whole House Humidifier Buying Guide

Whole House Humidifier Reviews

Use of It

whole-house-humidifier1It’s easy to tell whether your home could benefit from a whole house humidifier. If you or your family members have dry skin, are dealing with nosebleeds, your hair has a lot of flyaway static electricity or your infant is dealing with cold symptoms, you could benefit from a whole house humidifier. If any members of your household deal with allergies or asthma you will find that this type of humidifier reduces those symptoms significantly.

The pros of having a whole house humidifier

There are many pros to choosing a whole house humidifier when you need to add moisture to your living space.  We have listed these below.

  • An accurate humidity level is consistently maintained
  • It adds value to your home if you ever resell
  • Doesn’t take up any floor space
  • Runs through the furnace using the blower to circulate through the home and is super quiet
  • It’s connected directly to your existing water supply so you do not have to consistently add water

Things to Consider

Remember to take the following points into consideration regarding a whole house humidifier.  These points are not negatives but they are things that you will need to be aware of to have the best experience possible with your humidifier.  Even though the initial cost is higher, the unit will pay for itself over time with the efficiency it provides.

  • If the unit is not installed by a professional, licensed HVAC contractor or the warranty could be null and void.
  • A central whole house humidifier will need to be installed by a professional unless the homeowner is a DIY person that has the necessary knowledge.
  • If the water supply that feeds the humidifier uses a water softener you will not need to worry about removing minerals that come from hard water.
  • The best way to clean filters and the housing of the humidifier is to use distilled vinegar
  • Another great disinfectant for filters is bleach. This gets rid of bacteria and any mold or things of that nature.

Types of Whole House Humidifiers

whole-house-humidifier2

  • Drum Humidifiers – This type is the easiest to install and also is the most inexpensive. It is installed to the furnaces cold air return.  A belted motor pulls cold water from the drum and creates evaporation of the water.  The moving air puts the moisture out into the house. More maintenance of this type of humidifier is necessary in the form of belt replacements and cleaning to avoid mold from growing in any standing water.
  • Flow Through Humidifiers – This kind of humidifier is installed on the supply air duct or sometimes the return air duct. Either one is acceptable. These mid-priced, functional humidifiers work via a filter that water flows through along with ambient air that blows through the filter as well, causing evaporation.  You will need to hook this type of humidifier up to a water line so the water is constantly trickling through. Mold growth with this kind of humidifier is pretty much non-existent since there is no standing water.  It does not use any electricity either.  Water does need to be drained on a regular basis to avoid overflow.
  • Mist/Steam Humidifiers – This is the Cadillac of the humidifier world and is the most expensive to purchase. It is super efficient and produces steam rather than using the evaporation process the other two types utilize.  You can choose a cold water unit or hot water unit. The system introduces moisture into the air through cold or hot steam that is fed into the supply duct. You will hook these to the home’s plumbing with a water supply tube that is attached to the main water supply. It also requires electricity to operate so will use energy to work.  There is no standing water to worry about draining and mold growth possibility is very low.  The humidity level is easy to control via the wall mounted humidistat. You will need to be cautious of the hot steam that could cause duct problems so make sure you get the advice of a qualified HVAC contractor.
  • Central or Whole-House Humidifier Advantages

    A central whole house humidifier is a better choice if you are looking for a unit that you don’t have to mess with on a regular basis. These installed units are mostly set and forget and take the annoyance out of using a humidifier. All you really need to worry about in terms of maintenance is changing and/or cleaning the filter once a year. Once you set the humidistat you’re done until you need to change the settings.

    whole-house-humidifier3Standalone whole house humidifiers are a little more work and will need more maintenance and water refilling. Even though a central humidifier is more expensive, it is much more convenient and in the long run will be cheaper to operate and maintain. The humidifying results will be much more consistent and widespread when using a central line.

    Conclusion

    There are many things that warrant needing a good whole house humidifier. If you are building a home, it is a great idea to have a humidifier built into the duct system but even if you already own your home, adding one is not terribly difficult.

    Due to the nature of the unit, it is better to have professional installation unless you are someone that has done this type of work, or you know exactly what you’re doing.

    For anyone that has allergies, having a whole house humidifier will make a huge difference in your health. It is worth the expense to do away with dry skin, nosebleeds, itchy eyes and throat, and many other physical symptoms.

    The information you have learned here can be used to sort through available whole house humidifiers on the market and to make the right selection for your home’s humidity needs.
