Product review (5 stars): Excellent product, I highly recommend it to anyone who's ...
This product does exactly what it says and save me A LOT of day to day maintenance when I'm using my humidifier!!  Before using this, I was having to clean the humidifier every 2 or 3 days from the build up of white deposits from the hard water - and it was a BIG pain in the behind!  Not to mention all the possible bacteria that could have been breeding in there!!
Now all I have to do is add a capful of this marvelous solution to every water fill up and I can be confident the water is bacteria free and I don't have to clean it out as much - only 2 or 3 times a month!!  Excellent product, I highly recommend it to anyone who's using a humidifier with just plain water - you'll be very happy with the results!!
