Review on Essick Air 1970 2 Humidifier Bacteriostatic by Mike Maez

If you are careful, follow directions and by no means use it in a mist humidifier (this is for evaporative machines ONLY) it does exactly what it was designed to do which is prevent bacteria from entering and cleaning to a minimum. In my opinion this is a must. Just treat it with the utmost care, use it sparingly and keep it out of the reach of children (like any other household cleaning product). Tip: No fiddling around with measuring cups or the like. All you have to do is remove the cap, place the neck of the bottle securely over the reservoir wall and tilt the bottle slightly to release just a few drops (depending on the size of the reservoir). If you add this solution to the water when the level is still low, adding the extra water to the tank will allow the hot tub to mix it well enough. If foam appears at the top and/or you smell foam in the air afterwards, you have added too much and should dilute it even more.
