Query: Motor seized again

I purchased this humidifier two years ago and need to replace the motor again. The motor is not sealed and moisure from the system with all of the calcium accumulates in the gear box, seizing the drive. Cheaper to use an April Air and replace the elements despite the hard water that we have. This time I will install a seal on the shaft and hope that the motor will last longer. I do have to say that it does humidify my 1800 sq. ft. loose house well and is easy to clean the minerals off of even after a hard michigan winter.
