Product review (4 stars): definitely needed
I live in new york and i never thought i had hard water until i purchase honeywell warm mist, so yes they provide the mineral pad for a reason,and i'm certainly going to use it,because when i don't use it more work for me.so yes if you have hard water you definitely need this,yes i would recommend this.the mineral pad come in two stuck together, and thats is exactly how i use it and have no problem with the steam coming out. i change them every 3 to 4 days because its necessary.
