Humidifier Vs. Dehumidifier

I was recently tasked to do a research about furnace filters. At first, I was adamant about doing this and thought of passing it up because with all honesty, I'm still greatly confused about humidifiers and dehumidifiers..on as to when and under which circumstance should they be used. Thankfully, this assignment made me aware of the answer. It's not as confusing as it seems, actually. In a nutshell, a humidifier brings low air moisture levels to where they need to be. During winter time when humidity levels inside homes are low, a humidifier should be used so that the needed moisture are put into the air. On the other hand, it is mostly during summer time when a dehumidifier should be used when the air that we breathe becomes saturated with water, is sticky and harder to breath. High humidity levels can be brought forth down by a dehumidifier.

So there, as my son is prone to asthma when afflicted with cough, I know better now how to address his needs as the weather changes with the use of humidifiers and dehumidifiers.
