The "Humidifier Heavyweight": 50 Hours of Whisper-Quiet Relief for Large Rooms and Plant Parents!
The Everlasting Comfort 6L Ultrasonic Humidifier is the "Triple Threat" solution that solves all three. In 2026, where we are seeing a shift toward low-maintenance, high-capacity home wellness tools, this "Supersized" unit stands as the gold standard for large-room performance. The Engineering: 6 Liters of "Set-It-and-Forget-It" Power The standout feature is the 6-liter (1.6 gallon) tank capacity. Most standard humidifiers feature 2L or 4L tanks, requiring a refill every evening. In my testing, on the low-to-medium setting, this unit easily hit the 50-hour runtime mark. This makes it a "must-have" for: The Bedroom: You can go nearly three full nights without a trip to the sink. Plant Parents: Tropical plants like Monstera or Calathea thrive on the consistent output this unit provides, maintaining a stable 50–60% humidity level in a large living room. Maintenance: The Filterless Freedom The "No-Filter" design is a significant cost-saver. Traditional evaporative humidifiers require 15 – 15– 25 replacement wicks every few months. This ultrasonic model uses a vibrating diaphragm to atomize water, meaning zero recurring costs. Additionally, the wide tank opening makes it much easier to clean than the "tower" style models that often hide mold in narrow crevices. PROS Incredible Coverage: It is powerful enough to handle rooms up to 500 sq. ft. You can actually see the cool mist plume rising high enough to prevent it from dampening the floor. Essential Oil Tray: Unlike many humidifiers where you shouldn't add oils to the water, this features a dedicated aroma tray. It turns your nursery or bedroom into a spa-like environment without clogging the motor. Whisper-Quiet Operation: Clocking in at under 30dB, it is virtually silent. It’s perfect for light sleepers, babies, or home offices where you’re on constant calls. Auto-Shutoff Safety: Once the 6L tank is empty, the unit automatically powers down and triggers a red LED. You never have to worry about the motor burning out. 360-Degree Nozzle: You can direct the mist exactly where you need it—away from electronics and toward your bed or your plants. CONS The "Bottom-Fill" Design: This is a traditional bottom-fill tank. You have to flip the 6L tank over to fill it, which can be heavy when full. (See my Pro-Tip below for the fix!) Ultrasonic "White Dust": Like all ultrasonic humidifiers, if you have very hard tap water, you may notice a fine white mineral dust on dark furniture. Size: It has a larger footprint than "mini" humidifiers, so you’ll need a dedicated spot on a nightstand or side table. Overall Input The Everlasting Comfort 6L Humidifier is a masterclass in domestic utility. It treats dry skin, congestion, and allergies with industrial-scale power but does so with the silence of a high-end luxury appliance. It’s an investment in your sleep quality and your respiratory health that pays for itself in just one dry winter season. Reviewer Pro-Tip: To eliminate the "white dust" issue and keep your unit running for years, use distilled or demineralized water. If you must use tap water, I recommend buying "Humidifier Decleaner" fish or drops to prevent mineral buildup. Also, when refilling the bottom-fill tank, keep a small towel handy to wipe the condensation from the base before you move it! Who is this for? People with chronic dry skin or allergies, parents of newborns, indoor "jungle" enthusiasts, and anyone tired of refilling their humidifier every single day. Ease of use.

Great unit !! 2 directional mists, not just 1, that can be changed !
I love the ability to move the mist in two different directions of the room. Most only have one spray mist that can’t be changed. This one can go in 2 directions at the same time. Each can be moved in a full circle. This unit is attractive, very lightweight, easy to use, and quiet. You can’t even hear it running. Bonuses : a night light option and an essential oil tray if you want to use oils.

Quiet, and puts out plenty of moisture in our home. Never slept better!
Very quiet, although only get about 15-20 hours of runtime when reservoir is full and running at full output. But machine automatically turns off when out of water. Placed on night stand next to bed, and definitely makes a difference in sleeping comfort in our very arid (Utah) climate. Easy to refill, and did I mention how quiet it is?

Very good. Bought 4. Very happy. Refilling is tricky.
I have four of these, and they are very good humidifiers. Even with a whole house humidifier on one furnace our humidity levels in the house would drop to the 10% range during spans of cold weather when both gas furnaces were running often. This caused our wood floors to shrink, along with the dry itchy skin, and static electricity that happens with low humidity. Adding a another built-in humidifier on the second furnace isn’t an option due to the space where it’s installed. So, I initially bought three of these to place in different rooms. Running non-stop on high for a few days they raised the entire house humidity to the low 30% range, so I added a fourth one to the loft area over the great room. The house now averages between 35-50% humidity depending on how often the furnaces run, which is perfect. I can easily lower their output setting on the dial when less is needed. When running on high I typically have to refill the 6 liter tanks twice a day, once in the morning, then before bed. On lower settings once a day is enough. They are nearly silent. We don’t hear them running at all. No leaks, and the directional guide lets us set them to blow away from walls and furniture. My only wish is that they could be filled from the top or had a handle to carry the tank. It can be awkward and cumbersome when the tank is full and trying to carry it from the sink to the unit. I typically have to hug it with both arms and it will get drops of water on my shirt, and then dribble on the floor when flipping it over to set on the unit. Top filling would have been ideal. I have to carry a hand towel with me when refilling to wipe up drops off the wood floors. But otherwise they have never leaked, the water is just from having to flip the tank over to set it in the base. I do really like the LED lit water level window. It is very easy to see when they need to be refilled. I have not tried the tiny essential oil drawers, so no opinion there. Overall, I am very happy with these. Quality was consistent across all four. They work. They fixed our humidity issue, and life is much better when you don’t want to claw the skin off your legs every day from dry air.

Nice uint....Warranty issue?
Nice product. Sames to be working fine. One issue is registering for warranty. DON'T USE THE QR THAT COMES WITH THE UNIT! Way too much trouble. Didn't even ask for specific information on my unit. More interested in my contact information and e-mail. I'm guessing so they can send me more ads?

Does it's job well
So far so good. It is very quiet and does the misting well. Option to turn off the side blue light is thoughtful. The power button still has a small green light which I just taped over. If you want it pitch dark that's an easy 2 sec solution. Overall a nice unit. Filling can be tricky for some I would imagine but I just take the top piece off and there is a handle in there. Hold that and the bottom to be 100% safe and all is good.

Good humidifier but as a couple design flaws
Overall, this is a good humidifier. I purchased this unit because I'm been having recent nose bleeds sure to the dry heat in my house. I know it's lack of humidity because I'm 35 and I've never had this issue in my life. With this unit, the bleeding has stopped. However, I think the design could've been better. Cons: To refill the water, I take the cap and cover of the top and let the attached water droplets fall back down into the humidifier. Then I have to pick up the water tank and tilt it from side to side for water to drain back through the middle into the base. Doesn't seem like a huge deal until you're in a hurry and forget any of those steps and get a bunch of water in the floor as you're carrying it over to the sink. I feel like this design flaw could've been preventable with a little work more planning before production. Additionally, the most open area in the top for most air to be deliverable is actually pointed towards the back of the humidifier. The cap on top has directional slits to redirect the moisture back through the front (or be any other direction) but I just find it odd that delivers to the back first. Since my house is so dry, I actually have the humidifier sitting towards the wall so it can deliver more moisture to the air. That being said, I also have a small puddle of water next to the humidifier. Maybe I'm delivering too much moisture with the unit sitting backwards? Regardless, I'm fine with it until I get the humidity up in the house. I'll try turning the unit around like it was designed to be sitting and update my review if there's no puddle any more. I attached a video of these design flaws to show the water that accumulates in the top, cap, and cover. Please note the I had just refilled the water and the humidifier had only been running for about 2 minutes before I did the video. Just imagine how much water will accumulate after hours of run time. Also the video shows the moisture air outlet facing towards the back, but in my case, I turned the unit around to where it's sitting backwards to get more of moisture out into the room. Pros: large tank that can go about 24 hours before a refill using the max moisture setting. I've ran it dry a few times and the automatic shuts off has worked every time. I've never ran it on a lower setting for an extended period of time, but seems like it could last awhile. Love that there's no expensive filters that I have to buy all the time. Relatively quiet. I don't here it during the day. One night, I set it up in the bedroom to see if that would help the dry air upstairs and I barely noticed it was on. The blue LED light for the water level can be turned off too. I don't use essential oils, so I can't speak to that. Overall, I really like this unit. I feel like it delivers a lot of moisture to the air. If I needed another humidifier, I'd probably purchase another one. Although the above mentioned design flaws are annoying, it's all a good humidifier. There's so many bad humidifiers out there and this one actually works. Just take your time dissembling to refill the water tank and sit a plastic mat under it so it won't get your table wet.
