Poorly-Maintained Humidifiers

To be accurate, poorly-maintained humidifiers can be formed in multiple ways, but they can be a direct cause to breed microorganisms, bacteria, and other types of dirt.

The water inside a humidifier reservoir is the main element of a humidification process, but leaving a little bit of water inside a reservoir without cleaning or exposure to dirt, can turn it into a typical environment for breeding molds, bacteria, and more.

Those microorganisms can make their way into the core of a humidification system, becoming the main source of spreading hazardous health-endangering organisms into the air.

Moreover, normal types of dirt can also find their way into the core of the system if it’s not well-cleaned.
