GREAT Humidifier

I just got mine and I have to tell everyone to read your manuals! Luckily I do. I just happened to read the reviews here today for giggles and noticed the first two reviews people were complaining about the tanks. The manual says that the right tank empties first. Until the right tank is empty the left one will remain full. I've been using mine for a few days now and BOTH TANKS WILL EMPTY. The right one goes first and once its totally empty the left one will empty. Some people could save themselves a lot of money and time if they'd read the directions. Glad I was taught to do Thanks Kenmore for the great products. This is my third and I'll continue to get more.

Purchased this humidifier on Oct 28's now Nov 4 2013 and the unit has quit working. The display stays on reads so called current humidity in house but I have a separate readout that says it's 10% less humid in the house, so not accurate. Even if I turn humidity level up and fan speed to F3 it does not turn on. I have followed all the instructions for setup which is basically making sure it's level, placed away from heat duct, away from outside wall. It has water, float is activating switch for fans but nothing. Frustrating part is emptying and boxing the unit back up for return and also finding out after being on hold for sometime with my local Sears store that the 2 units they are showing as being in inventory are not, they have no replacement for me. What has happened to Kenmore products? Made in ?

Excellent Humidifier - Very Quiet


Excellent Humidifier - Low Speed is Very Quiet - No high frequency noise. High speed works fast. Large bottles of water last 2 days in northern winter. Easy to fill. Accurate humidostat. Can dry filters automatically (let run dry) to ****** mold without bacteriostat.

Kenmore Humidifier


I purchased this on December 10, 2016. I only used it for one season and it quit working. There is a two year warranty on the motor but Sears wants me to drive over 30 miles and take it to a service center. Won’t be dealing with Sears anymore. No wonder they are going out of business.

Can't get replacement filters


I purchased this humidier last winter. It worked great but I have now spent 5 weeks trying to get replacement filters. I only get promises for an answer. I have received 3 emails backing up the delivery date.

I will never order a product from again.


I ordered a new humidifier from because it was out of stock in our local stores. I paid full price, but free shipping was a nice feature. I received a used humidifier with dents in the top and used filters with water stains installed inside. I returned the used humidifier to our local store and they were very helpful on refunding my money. I was very disappointed to not receive a new product.

Pretty Good Humidifier


Only problem we found was one of the two hinges was broken when we opened the box upon delivery. Because replacing something like this is such a hassle, we just kept the unit with a broken hinge. Other than this, it seems to be working very well.
