Reliable helper for cleaner, fresher humidifier wa

Using this bacteriostatic treatment with my evaporative humidifier has made a noticeable difference in how fresh the unit smells and how clean the tank stays between complete cleanings. A small capful in each refill has been enough to keep that musty, “stale water” odor away and cut down on slimy buildup on the reservoir and wick, so the filter seems to last longer and the whole setup feels easier to maintain. The liquid itself is a light green color, but it has not stained my plastic tank, and once the humidifier is running, there is no strong chemical smell in the room, which matters in a bedroom. One 32‑ounce bottle goes a long way because you only use a little at a time, so it feels like good value for the money if you run a humidifier daily throughout the dry season. The only downside is being careful with dosing and remembering that this is meant for standard evaporative models, not ultrasonic or warm vapor units, but as long as the directions and the humidifier manual are followed, it does precisely what it promises.

After refurbishing a humidifier in expectation of having a tracheostomy patient in the house, I spent the extra money on Refresh C because a little extra immune support can't hurt, right? But when it came time for a refill, and it's winter so we're going through it FAST, I figured I'd try the regular bacteriostatic. I'm not having any problems with hard water deposits or murky water, the only thing working overtime seems to be the filter, but as long as i rinse it regularly, it doesnt turn into a rock. This product smells amazing. Not strong. A barely there type fragrance thatvis fresh and clean. I'd only noticed when thenbottle was open before, but i cleaned the whole ynit last night and you use more product the refilling the humidifier after maintenance. Walked out of my room this morning and the house smells awesome. Very light, barely there, but noticably better than when i went to sleep. Will continue to purchase, the scent makes me smile.

Great Product for Your Humidifier

This is simply a great product. I use it every time I fill my humidifier. I have used it for probably 3 years or more. I have never had any "crud" in my humidifier system.
