I’m going to be analyzing some of the best whole house steam humidifier preferable for the winter. Running steam humidifier during winter is more economical than running your home heating furnace because steam humidifiers use lesser energy. Also there are portable and whole steam humidifiers. The portable ones serves best for single rooms while the whole house types are best for whole house humidification.

So if you want to purchase a steam humidifier consider if you will need it to for whole house or single room, because whole units are installed in a permanent place. This means it can’t be carried once installed. On the other hand, if you want a unit that can be use in any room of your choice, portable steam humidifier such as the boneco s450 is the option to meet this need.

Note, do not mistake warm mist humidifier for steam unit because both are totally different in the kind of mist they produce. So my advice, choose your unit accordingly. If you need warm mist pick a unit that deliver warm mist and if you need steam mist also pick a steam air humidifier. Since we’re discussing about whole house steam, I will further show you some units and their reviews each.
