This is by far the best humidifier I've ever had. Living in a cold weather climate (MA), I need the humidity to counteract the effects of dry air. Otherwise, I get nose bleeds all the time. I took a chance when buying it as there were no reviews for me to read. It is pretty much as advertised. The 1.6 gallon reservoir has an easy-to-pick-up handle for refilling. The cap is a bit difficult to unscrew, so I put a lubricant on the threads to grease it up which helps. It does shut off automatically when dry/empty. It's very quiet and does not leak. I put it next to my bed and it doesn't disturb my sleep at all. It's very easy to clean. Use a little white vinegar once a week. Just put the ceramic nano-silver filter in cup of white vinegar for ten minutes and use a few drops of vinegar to clean the sensor. No need to buy new filters, cartridges, or mineralization pads. I have noticed a little white dust in the room, but far less than the Bionaire ultrasonic humidifier I used to have. The Hygrostat sensor indicates the humidity level. Not sure how accurate it is though. Mist output can be regulated: low, medium, and high. There is a button to produce negative ions. I use it, but don't really know if it makes any difference in the quality of the air. I have yet to try the warm air mist, so I can't comment on that. And lastly, there's no way I can get 60 hours of continuous use without refilling, not unless I want my room to stay dry which defeats the point of having a humidifier. Two nights is more like it. You might get 60 hours if you put the humidity level at low or at a desired level of 45%. I can't comment on how much electricity it uses and I don't know how long it will last. I've had it for one week and so far and I love it. I highly recommend it.
I tried this unit and filed for a return after one week. I bought the unit despite it having only three reviews. Now I question these reviews because they all gave five stars and I completely hate this product.
CONS:
1) The manufacturer claims "High moisture output can quickly humidify a room up to 40 m² (430 ft²)." No way. I have a 10' x 16' bedroom and I am waking up with dry eyes and mouth even though our outdoor temperature lows have only been between 33 and 57 degrees Fahrenheit this week. I had the unit on maximum ouput the last night of my trial. It would only be worse when our heat is running more frequently during the night.
2) If you are light sensitive when you go to bed and you intend to put this in your bedroom then this unit is not for you. It radiates blue light in every direction. There is a bright blue light bulb with the only purpose of shining through the water tank. It does not dim and I can't find a way to turn it off. The manufacturer's picture of the unit shows a blue glow around it -that's not for marketing, that's exactly how it glows. It's very annoying.
3) There is also a blue LED display that automatically dims a level after a minute or so but not near enough and there is no way to turn it completely off. If you put the unit on automatic to control humidity then the LED situation is worse because the word "setup" flashes FOREVER while in that mode.
4) Despite all of this irritating light there is no light where it might be positive: on the buttons of the unit and its remote control! I tried to crank the unit up to its maximum setting in the dark and even though I could see this bright blue cube of water in the room I could not read the controls. I had to turn on the bedroom overhead light which disturbed my wife.
5) From the same night-time-adjustment incident I discovered another annoying thing: each button press beeps loudly. The next day I could not find a way in the manual or through experimentation to disable the beeping for every button press.
6) There is no way that I can find in the manual to change the temperature gauge to read in Fahrenheit versus Celsius.
7) The company does not honor Amazon's expedited shipping policy... but they will charge you for it. I ordered this way and they did not ship to me within two days. I had to email them and then a day later I got a shipping notice.
8) This product is far too much more expensive than other ultrasonic humidifiers and for no justifiable reason that I can discern.
PROS
1) The unit operates quietly when compared to an evaporative humidifier. But so did every other ultrasonic that I have ever owned or observed. That's the pro of going with ultrasonic technology for a humidifier.
2) I like the promise of its "Permanent, easy-to-clean ceramic nano-silver filter for control of white dust, mould and bacteria." I did not see any white dust during my trial week, I can vouch for that. But will the filter last for a long time? I don't know. My bet is that some plastic part will break from handling the unit and the tank at some point and one would need to buy another humdifier before this particular filter gave out.
For now I am switching back to my evaporative humidifier. It's loud and it takes filters and additives to keep the water and air clean but it actually gets the job of humidity control done which is job #1.
Buy Heaven Fresh HF 707 Digital Ultrasonic Cool and Warm Mist Humidifier and Ionizer - with Remote Cont Now
We needed a humidifier for our lab and spent many hours researching different options. We chose the Heaven Fresh HF 707 for 3 reasons:
* Ceramic nano-silver filter humidifiers are magnets for mould and bacteria, so this is a must
* Built-in Hygrostat set desired humidity and it automatically maintains that level
* Built-in negative ion generator, excellent for cleaning and sanitizing the air
The first unit shipped to us was missing a part, and we urgently needed a working dehumidifier. We called the seller, explained our situation and the seller agreed to send a replacement by 2nd Day Air. The replacement arrived and worked like a charm.
It's hard to tell from the picture but the unit has a very nice digital display that shows the ambient temperature and humidity. This isn't the cheapest humidifier on Amazon, but if you look carefully all the other humidifiers have quite a few negative reviews. Buying a quality product is always cheaper in the long term.
Overall, we're very pleased with our purchase and the great customer service. Would definitely buy from them again.

I like all the useful functionality included in this humidifier. Auto dimming LED, timer, humidity-level control, displays room humidity and temperature (even when powered off, but plugged in, of course :-P), negative ions (though I can't say I felt it and I don't know the spec for the -ion output rate), and remote control. I find them all useful. I will probably also use the warm mist function when it gets cold.
Only complaint, when I set humidity to 65%, it can only push room humidity to about 59%. When I set it to 60%, it works up to about 55%. I use it in a small (~160 sqft) bedroom, and I usually leave the door open by an inch, but windows closed. I live in SF bay area, where humidity level is usually around 45%. Because of its laziness, it does do a good job of saving water. With this relatively small tank (easy to handle), it lasts about 7 nights for me, about 70 hours.
Want Heaven Fresh HF 707 Digital Ultrasonic Cool and Warm Mist Humidifier and Ionizer - with Remote Cont Discount?
I've owned a lot of humidifiers over the years. The HF 707 is a minimally satisfactory product for basic humidification. The two units I've used have both reliably put out a lot of water into the air, which we need in winter here in New England. We use it in a 12x12 room, and regularly maintain 45-50% relative humidity, as measured by a separate hygrometer across the room (which I recommend you use, as well). The machine's integral hygrometer gives highly misleading readings and should be cross-checked with another instrument. The machine's integral thermometer gives fairly accurate readings. Both readings are thrown way off when you use the heating option. Like most ultrasonic humidifiers, it leaves a deposit of white dust on nearby surfaces, but somewhat less so than our previous Air-O-Swiss.
Order fulfillment is direct from Heaven Fresh, so I ordered direct from them as well. I ordered a black machine, and they sent silver; when I called to get the situation corrected, they explained that they had no black units and that's why they shipped the silver. (What happened to back-order? They seem genuinely puzzled that I would complain.) They promised me the black units had just come in and they'd ship me one right away. Three calls later, three similar promises, finally insisted on talking to a supervisor. He promised it would ship in three days, and it did -and it is black, but from a batch they received from their Canadian branch, so the temperature is displayed in Celsius, not Fahrenheit. When I called them, they said they were out of US models so they shipped me the Canadian. Again, genuinely puzzled that that wasn't okay with me. They offered (again!) to ship me a replacement -but this has turned into a too-long farce already, and I declined.
If you decide to purchase anyway, good luck. I'll be looking elsewhere for the living room unit.
Very easy to use. The large digital screen makes it so easy to read. Like the compact size, fits in my pocket, makes taking multiple Readings in several areas simple and quick. There is a short delay in readings, about 5 seconds or so, but the readings have proven to be accurate. The Minimum/maximum data storing feature is great to keep record of varying temps in day to day use. A good deal for a good product.
