Winter brings along dry cold air. With COVID-19 still about, it’s important to remember that the virus thrives in dry, cold environments. To keep your family safe, you should consider getting a central air humidifier for your heating and cooling system. And so, today, let’s look into what a central air humidifier is, and what it can do for the air in your home.


Why You Should Consider Adding an Air Humidifier to Your Central Air Conditioning System

A central air humidifier helps tackle some of the unpleasant attributes of winter, such as dry air, static shocks, breathing difficulties, irritated throats, and itchy eyes.

Low humidity levels are very bad for your skin and throat; however, it’s even worse in the case of the COVID-19 virus as they thrive in humid and dry environments for longer periods. Therefore, adding moisture back into the air with central air humidification systems allows you to prevent the virus from lingering around for too long. Moreover, humid air moisturizes your internal mucus membranes, thereby increasing your ability to fight the virus should it enter your respiratory system.


What is an Air Humidifier for a Central Air Conditioning System?

A central air humidifier connects to the ductwork of your furnace along with the plumbing system in your home. From there, it uses the water from the plumbing and uses heat from the gas furnace to humidify your air.


What are the advantages a central air humidifier has over a standard portable one?

As there are two types of humidifiers, it’s important to distinguish between the two. A central air humidifier has quite a few benefits over the standard portable one. These include:

  • A central air humidifier can regulate the humidity in all the rooms of your home. On the other hand, a portable air humidifier is only effective in the room it’s located. Therefore, if you switch rooms, you’ll be greeted with a lung full of dry, uncomfortable air.
  • A centrally connected air humidifier requires far less maintenance and upkeep than a normal air humidifier as it connects to the plumbing system in your home. As a result, it does not require a refill after a day of use and has a constant supply of water.
  • A centrally connected air humidifier is located out of sight. Therefore, it generates less noise and is less likely to be a hazard when walking around. In the case of a portable air humidifier, it generates noise while operating, and you need to be careful not to walk into the blast of steam.
  • A central air humidifier is more energy-efficient than a single portable air humidifier. This makes a central air humidifier the right choice when it comes to improving the air quality in your home through a harsh winter.


3 Types of Air Humidifiers You Can Get for Your Air Conditioners and How to Maintain Them

There are three types of basic central humidifier types:



The flow-through type is the most common type of air humidifier used for central air conditioning systems. Here, water trickles into an aluminum panel, and hot air blows across the panel, resulting in water vapors.

The flow-through humidifier requires less maintenance and the evaporative screen pad needs replacing after each heating season.



A rotating rough porous surface foam or sponge absorbs water from a tray. This water then evaporates and feeds into the ductwork of your home.

This type requires regular maintenance and attention as the water from the tray might become stagnant, and so, should be emptied often. If left unchecked, the bacterial growth from the stagnant water, along with mold spores will get into your main air ducts and spread across your home.


Steam Humidifiers

A steam humidifier regulates the humidity in your home by boiling water from your plumbing system electrically and passes the water vapor into the air ducts along with conditioned air.

A steam central air humidifier automatically flushes stagnant water out of its water tank and therefore does not require regular maintenance. However, after each passing season, it’s recommended to clean the tank and nozzles, as they may get dirty and clogged due to debris and dirt.


With regular AC maintenance & repair, you should be able to maintain all types of air humidifiers with ease. Therefore, get in touch with AC repair specialists in your area after you purchase a central air humidifier.



Now that you know the importance of having a central air humidifier, especially in the times of COVID-19, it’s time for you to contact your local HVAC companies and get one installed in your home. Equipped with the maintenance knowledge, you can make sure your family is safer from COVID-19 and other diseases which thrive in low humidity environments.
