Product review (5 stars): This product works!
What a great product!  I use it for my iron and humidifier.  Living in Arizona, our water has lots of minerals.  The use of the BestAir product prevents the usual buildup that occurs.  After trying several other brands, I was delighted to find that the BestAir brand actually works!

I also use this product in the water I use in my essential oil diffusers.  Since having to get rid of two because of the mineral build up, I am certain that my new diffusers will be around longer than their predecessors.
