Query: Don't Waste Your Money

After filling the water tanks, the unit failed to start. The humidity level indicated 94% humidity and the motor wouldn't start. I contacted Essick Air and was told there was probably a failure of the built-in humidistat. I purchased my unit from iallergy.com. Upon contacting iallergy, the representative confirmed that they sold a batch of units that failed to work as designed due to humidistat/motor problems. They offered to replace my unit for free. Big deal. When I got the replacement unit, it worked but it is very noisy and the motor sounds like it is going to fail at any second. Do yourself a favor and get a SEARS Kenmore 12 gallons whole house humidifier. That is what I always used in the past, but they were sold out so I bought this unit. Big mistake!!!
