    Customer has been confirmed to have purchased the item from Walmart.

    We needed something to humidify the downstairs, and this is undersized but does put humidity into the air. It draws about 300 watts on low and about 500 on high, so we're only using it at night to keep the electric bill down. One claim is about no gurgling due to the little filter they put on the heating element. That means the bubbling boiling sound, you still get the occasional glug as water drains from the tanks. You need to place it on a flat surface to allow the tanks to drain evenly, we have an old house & had to find a level spot for this to happen. One issue is I don't think the shutoff switch works, I don't think it can push out when the tank is empty, so i'm keeping an eye on that. Also, when that switch is pressed when the tank goes in, it doesn't start the humidifier immediately. Probably to allow water to flow to the heater before turning it on - but that delay isn't mentioned in the manual. On low, this drains more than half the tanks overnight (10hrs-ish), so it does put a good amount of moisture into the room = it does its job :)

    I like the product. It works well and delivers more humidity to my house then my humidifier that is built into my furnace. Worth the money and I like the sleeve option to protect the heating element - however, the sleeves are hard to find. Wal-Mart does not sell them and when I contacted the manufacturer, they are out until sometime maybe in January. Told me to keep checking back. The safety switch is an understandable idea, but a real pain if you do not have this system sitting completely level (which is hard to do if 1 tank is empty and you are on carpet).

    We have a wood burner in our home. This works great!! No more bloody noses. It really puts out. In fact I believe it does more than just the 20'x20' family room. I think it helps keep our whole ranch styled house moisturized. Very easy to use and clean. We used to have the old Honeywell model # HWM-450 (4gallon) which is not made anymore. I think this Optimus (so far) puts out more. We have had it for about a month now. Cleaned the sock on the bottom of the element (had calcium deposits). Simple to use and clean. I told my sister-in-law about it. I believe she is going to purchase one too. In fact, we use this everyday whether or not we are burning in our wood burners.

    This humidifier would have been awesome except for the fact that the wicking sleeve needed to be cleaned every day, which entails taking the unit apart to do. We tried to purchase more wicking sleeves but could not find any available anywhere. Every one was sold out and they are not available at the local Walmarts either. The tanks only needed to be filled once per day which was great and the humidity output was wonderful. We ended up and returned ours due to the fact that every day we had to take it apart to clean the wicking sleeve and we were unable to purchase any new ones.

    It's a hassle to clean, but reduces heating bills by keeping humidity up. By the time the sleeve becomes useless it's worth it to buy another unit or try making a sleeve for it. Cuts down on static electricity when touching metal because of humidity higher.

    The dual tank is nice since it reduces the weight of the carry. The tanks are easy to fill since it sits flat in the sink. The caps are easy to remove. It does use a large area wherever it is placed. Quiet operation. My issue is the humidistat is almost useless. It switches on at less than 40% and off at above 55% at its current setting. My prior Honeywell unit controlled to within 1% of a setting. Update at 33days: The humidistat is not working since it is either off or on. Humidity has ranged from low 30% to over 60%.

    I've used it over 1 week and have not had any issues. It's quiet, unlike the cool mist humidifier I was using last year. I like that it holds 3 gallons of water, so I don't have to fill it often. I keep a towel under it because when you take the tanks off to refill, it is wet on the bottom and drips until you turn it over, not a problem for me.

    For the price it is a good deal. I had a small problem with mine when I got it one of the handles was not glued on all the way, But was quicker to fix it than return for a new one. As I burn wood for heat the house get to dry in the winter, In a matter of a couple of weeks things around the house felt better and my skin was not so dry. Next year will start it in the fall and get the true test on how well it does the whole house. But dollar for dollar it is cheap fast and easy to use.

    I purchased this item specifically because the description indicated that this unit had a setting for "medicine cup" to be used with vaporizing medications. THIS MODEL DOES NOT HAVE THIS FUNCTION! Seems okay as just a humidifier, but if you need the additional function of the medicine cup, PICK ANOTHER ONE! Extremely disappointing that the basic info for a product description aren't correct, especially when they completely change how you're able to use it.

    I just bought this humidifier a week and a half ago. It shuts off at 35% humidity. I turned it up, but it still goes off 35%. I have unplugged it and plugged it back in. Still turns off at 35%. I have switched the water tanks around and then back around but nothing works. How can I get the humidity up to 50% in my house? Thanks for your responce Lisa

    • A. Why would you want it so high in the house 35% is more than most people need in the winter. You might try moving it from room to room or run fans to move the air around.

    • A. The only thing I can think is that maybe the area is already reaching it's top humidity level. If you read the manual I believe they turn off automatically when they reach their top level. When we are not burning in our wood burner I have had one shut off at a certain mark. You may want to contact the manufacturer otherwise to make sure no defects. Plus keep in mind if it's a small area it wiil acheive its maximum quicker. Hope that helps.
