My air innovations keeps on beeping when the reservoir is filled

Hello... this humidifier uses timer? then, some humidity has damaged the circuitry. Try to disassemble as far as your skills permit; then put the unit outside of home in a place where the sun and wind can dry this device. And try to use destiled water if is not expensive in your area.

My humidifier which is suppose to mist seems to only have the fan blowing. No mist. Lost the manuel and the machine was purchased in feb of 11. What is the solution?

It may have a scale and calcium build up. Particularly, if you use well water.

To clean it, unplug the unit and empty in water that is in the tank. Mix a 50/50 solution of White Vinegar and Bottled Distilled Water (enough to fill the tank. Pour the solution in the tank and allow it to set for 2 hours. Then turn the humidifier ON and place you hand in front of the misting nozzle , to feel if it's working. If it is, allow it to run until the tank is 3/4's empty, Empty te tank of the remaining solution and refill the tank with more Bottled Distilled Water and run for an hour. This will flush the 50/50 solution out of the system. It it wasn't working when you first tested it, allow it to set over night and try again the next morning.

In the future, use Bottled Distilled Water rather than tap water.

95% of the time, this will solve the problem. I hope this helped you. Please let me know.

Aprilaire 550 has exploded with water

No water should not just sit there in the system. It is supposed to recirculate itself. You should really call a tech out and have them check your system.

1 tank empties at once, overflow all over floor.

Ever find a solution to this? I had the same bug after 2 years working fine, felt stupid as I couldn't understand it. I replaced both tanks for no good reason then it worked fine, took it out this season and it's doing it again.

Kenmore 14-gallon humidifier--only right bottle will drain

I just read the reviews because I am considering buying it, and many owners complained of the same problem. Many people said they tried to fix the problems by leveling the machine, however, one guy said he figured it out: just level the machine slightly toward the REAR and it drains correctly. Try it. I hope he's right, because I'm going to take a chance on this machine and it better work well!!! :)
