Query: Great humidifier, while it lasts!

We purchased this last year - Although it was a bit noisy, and worked great (Humidifies the entire floor), it broke down after 4 months (motor burnout). Luckily, Sam's Club let us exchange it for a new one. Ran great last year, but it broke down again (motor burnout) this year, after about 6 months of service (over 1.5 winters).It appears that the fan motor is of low quality, and burns out with the moisture usually prevalent in such units.
