Product review (4 stars): Super Golden Solutions
I like this product and have quite a few bottles left, but this year I am going through filters faster than in year's before.  Is it the weather, the Humidifier Combo Treatment, my house, who knows?  It could be that it has been a really cold winter and the humidifiers have been working overtime.  I have a husband with COPD and really have to keep an eye on bacteria in the units so I want the freshest water so I just hope it's not the Combo Treatment.  I will continue to use this since it seems to be the best product on the market right now.
