Dreo 6L Humidifiers for Bedroom, Smart Warm & Cool Mist for Large Room, 60Hr Quiet Runtime for Baby, Plant, Humidity Sensor, Indicator Light, 12H Timer, Google/Alexa, HM713S

To be honest, this is my first humidifier. I ended up getting this, because my home was really taking a toll in the summer heat, especially with the A/C running. It also runs really quietly. Because it's so hot where I live, it was definitely a practical purchase. The moment my A/C turns on, the unit's indicator shows that humidity drops 2-3%. Being without this unit, I can see why my home was feeling so dry. Thanks to this, my head doesn't hurt as much, and I'm starting to feel less parched on a general basis. Auto mode has been keeping the humidity at a desired level, and the amount of mist it emits can be set between low, medium, and high as well. While I don't intend to use the heat function ever, it is a nice extra feature (I have a dedicated vaporizer I'd rather utilize in the winter for more heat instead of using this). Anyway, I will be coming back to this review if any issues arise, but so far, it's been working great to meet my needs. The only thing I don't really like about this purchase is the manual. It was not printed with sequence in mind and some pages are even upside-down, so I have to separate the pages to read it in order based on the table of contents.Admittedly, the Amazon Resale was really enticing to consider, because of the base price for this product. While my experience isn't necessarily a major deal breaker, I still feel it's important to reflect. Basically, although I bought the product in 'Like New' condition, it was definitely previously used at least once or twice, and not really as described on the condition notes. There were definitely water marks to suggest it's been used. For that matter, even though I bought 'Like New', it really matches the 'Very Good' Amazon Resale listing they have instead. Mine definitely had a few cosmetic dings on it. There was a scrape on the unit itself and the tank had a couple of scratches and a large scrape mark consistent with someone packaging this a little carelessly. It's also missing one of its rubber bases. According to the manual, the product was also supposed to come with a cleaning brush, but that was not included with my unit. Really, it doesn't necessarily change that much for me, as I'll probably use a cloth to clean my unit, as the manual suggests instead of the brush.So yeah, mostly minor stuff to mention; granted, when the condition doesn't match, it's still somewhat peculiar. These aren't exactly the standards Amazon expects of its third-party sellers when selling items in less than new condition on their platform, so kind of disappointing when the platform itself isn't as mindful. Whatever the case, it might be something to consider if you choose to go the cheaper route. Again, not really a deal breaker, as it's still a really nice price for a unit, even if it's not as stated in its condition notes.

Excellent devise. Extremely quiet, easy to set up and use. Programmable app that is intuitive. I have been having terrible nasal pain, been to three doctors, the last one finally told me that it was because of dryness. She suggested over the counter meds and a humidifier. I bought the smaller version of this and liked it so much that I got the larger version. My pain and headaches have gone away and I am finally comfortable. In fact, I often don't even use the meds. Wish all purchases were this easy.

I rarely give 5 stars because that means nothing can be improved. But this one earned it. I am not a paid person nor do I get any benefits from this review. I ordered this product for my large bedroom during the night. The noise is essentially not audible. The moisture level was great. You can control what percent of humidity you wish to have. It was what I needed. It am giving it a 5 star for the product support. The cleaning is fairly straight forward. I was wiping it down as instructed and piece popped off and I could not figure out how to put it back. The instructions were all online as expected, and I could not find anything that made sense. This was frustrating. I called the company directly and got useful and accurate information about my problem, and the company sent me out the piece I needed (after providing some photos with the information they needed). So yes, there was an issue and I had to wait for the part to come in, but nothing is perfect and this problem was handled wonderfully. Jane (on the phone call) and Carol (on the email conversations) were both professional and personable, and they gave me full help to correct the issue.

Although I am not really an expert, I do have some background in water chemistry that I am applying to this review - so please excuse its length!For decades we have used a traditional vaporizer. This works by passing an electric current between 2 electrodes inside the “cup” submerged within the vaporizer reservoir. This produces steam that emerges as hot mist. One disadvantage of this approach is that it can burn small children and pets who get too close. Another is that if the water is “hard” (contains too much calcium and/or magnesium), then calcium and/or magnesium carbonate will precipitate out forming scale. This eventually coats the electrodes, preventing them from transferring the electric current. Also, the electrodes eventually corrode. On the other hand, if the water is too pure, electric current will not pass through it. In this case a little table salt (sodium chloride) can be added – the more you add, the more vigorously steam is produced. Overall, these vaporizers work well, they just “burn out” every few years. Also, there is little control – they run until the water drops below the level of the electrodes. Since almost all the impurities stay behind as the water evaporates, the scaling potential and salt content increase over the hours of each run.In order to reduce the potential for burns and to gain better control over the room humidity, we looked at this Dreo HM713 humidifier with its options for both cool and warm (not hot) mist and a humidity control option. It is an ultrasonic model, breaking the water into very fine droplets that are emitted, rather than to steam. That means most of the impurities are emitted in the mist. Then as the water vapor evaporates from the tiny droplets, the solids (such as the calcium and magnesium carbonates and sodium chloride). are left as tiny airborne particles, or “white dust”.Some negative reviews complained of a fishy odor. Such odors generally come from organic compounds called amines. The precursors for these compounds may be in the water supply, but I suspect they may have been added unintentionally by ion exchange compounds present in some home water purifiers. Another common complaint was the fine white powder, which is likely the scale compounds and/or salt mentioned above. As I suspected, we had no trouble with odors (fairly good quality public water supply). However, I was surprised and somewhat alarmed over how much fine white powder was generated. The likely carbonates and salts that produce it are safe to eat or drink, but I am not sure about inhaling them deep into your lungs. I was also concerned that they would quickly overpower the air purifier that we bought recently because of the Canadian and more local forest fires. To avoid the particles, you can use distilled (or reverse osmosis) water (not bottled or filtered or softened water – it must be demineralized).So, our solution (at least for now) is to use an old-fashioned vaporizer during the day, when we can manually turn it off if the room moisture level gets too high (greater than 55-60% relative humidity), and use the Dreo filled with distilled water at night set at a lower moisture level (45%). I do wish we could turn the built-in night light off without also turning off the humidity control. I am also not crazy about buying distilled water in single-use gallon plastic jugs, although we do get 2-3 nights out of a single gallon for our small room.Both humidifiers should be cleaned frequently and thoroughly to avoid microbial growth. One problem with the old vaporizer is that it is difficult to get all the water out and your hand in to wipe it clean. In that regard, the Dreo is much better.
