The Capacity Of Your House

Your choice of humidifier must have the capacity to cover the entire area of your house. Most of the products do reveal the space it covers in square feet, and it has to match your intended area. Also, the covering area must not exceed your houses’ space as well because it will leave you with too much humidity.

How to install a Whole House Humidifier?

Actually, the installation procedure can be different from brand to brand, and we urge you to follow the manual’s instruction as much as possible or to get professional help. Anyway, we will guide you through some basic steps to install a whole house humidifier. 

  • First, mark the places you are going to fit the humidifier with a marker. Drill holes using a drill and finish it off with snips.
  • Now attach the mount plates using a screw and do the same for the humidistat holder as per the instructions given by the manufacturer (there is a specific distance from the humidifier to humidistat and this distance can vary from brand to brand)
  • Now connect the required wires from mounting plates to furnace controls. 
  • Then you can place the unit on the mounting plate and screw; connect the cables.
  • There you have it, fill the water reservoir, and now you are good to go with your humidifier. 

Special note: this is just a general guideline. You must always read the manual carefully before you install. If you deviate from the manufacturer instructions, you may lose the warranty as well.

How do Whole House Humidifiers Work?

Whole house humidifiers can be found in portable/small ones to feature-rich models. The best whole house humidifier can come with loads of options and features. However, we can divide all these types into three basic sorts; evaporative humidifiers, steam humidifiers and evaporative cool mist humidifiers. 

On most occasions, evaporative and steam humidifiers work as central units which means one machine provides humidity for the whole house. Meanwhile, evaporative cool mist humidifiers are often portable and designed to cater to one or multiple rooms only. 

A humidistat handles all three sorts.

Inside of these machines, there is a humidifier pad (water panel), a rotating drum or a unique steaming system to provide humidity to your home’s air. All three methods would do one thing, which is converting water into humidity; keeping you safe from germs, viruses and other skin related illnesses.

Having a humidifier is ideal for your household items as well, because appropriate moisture would enhance the longevity of the appliances. 

Ducted vs Non-ducted Whole House Humidifiers
