Sunpentown Dual Mist Humidifier

Effectively relieve dry nose, throat lips and itchy skin with the virtually silent Dual Mist Humidifier with ION exchange filter. Will help you breathe easier and sleep more comfortably. This ultrasonic humidifier disperses warm or cool mist. A split nozzle for bi-directional mist for wider coverage. Sleek design with easy to use control knobs. Large, transparent blue water tank with easy-carrying handle. ION exchange filter demineralizes and treats water to reduce scale-forming calcium and magnesium from hard water. This prolongs the life of the ultrasonic generator and prevents white dust particles to deposit into the air.

    Does the job.

    from Brooklyn, NY – Verified Buyer

    This humidifier works well for my bedroom. It not only makes it easier for me to breathe the overheated, dry winter air, but it is great for my plants. I don't have to water them nearly as often, and the ones that were struggling seem to be doing better. I think I will buy at least one more for the area where I spend my days. I think it will make my pets more comfortable too. It is a bit of a pain to refill the tank. It's hard to do it without spilling at least a little bit of water. But my floor is cement, so it doesn't really matter. I just keep an old washcloth nearby, and wipe it up. I don't have to refill it more than once a day, depending on how high I want the humidity to be. Cleaning it once a week is easy, and if I used distilled water rather than water from the tap I would probably only have to do it once a month. The controls are simple to use and the instructions are clear. Overall I am happy with the product.

    Great product - works fantastic, arrived new and in okay packaging.

    from Vermette, MB – Verified Buyer

    This humidifier works great. We used to have an old room humidifier from the 1980's which finally packed it in. The old humidifier had some build up from treated well water, so I was a bit leery of the same thing happening here. No problems. Consumers reports also currently (March 2015) lists this humidifier as one of the highest rated room units - I'm not disappointed!

    Small and Quiet

    from Bedford, MA – Verified Buyer

    This humidifier does the job by adding moisture to my bedroom, making it more comfortable to sleep. Because it is small, it needs to be refilled in the morning and at night, but it is lightweight so that hasn't posed a problem. I actually like that it turns itself off and displays a red light if it uses up all of the water supply. I noticed the red glow one night and got out of bed to do the refilling task that had been forgotten. A good unit.

    from Toronto, ON, Canada – Verified Buyer

    I have been using SPT Dual Mist Humidifier for a couple of weeks and I really like it. I breathe much easily, the quality of air in my apartment significantly improved, my plants, especially palm trees, look much better; practically this humidifier saved lives to my tropical plants. It is very easy to operate. The humidifier evaporates about 8 litres ow water a day. I can highly recommend it.

    Quality Device -- All Frills, No Spills

    from Denver, CO – Verified Buyer

    I actually picked this up for my new piano in the dry Colorado clime - no babies involved - and it works like a gem. I had to check that it was working the first time I turned it on, it's so quiet. The fine mist lets you know it's working. I was somewhat wary of forking over the extra bucks for this but I'm glad I did. It runs efficiently and is large enough that I don't need to fill it more than once a day - no more than every other day if it rains. Be careful when refilling it, though, as it tends to spill.

    Works well, can be a bit noisy

    from Pittsburgh, PA – Verified Buyer

    You can feel the increase in humidity within only a couple of hours, in a small to mid-sized room. I added a filter cartridge to the tank, and there has been no noticeable residue or odor during my 4 months of ownership. It lacks a humidistat, which I feel should be included, in this price range. It is unpredictably loud (when trying to sleep near it) or quiet. The humidified air that it blows is rather cool, and it can affect the overall temperature of a small room.
