submitted by Help please - 1 year ago
A: We're sorry to hear that you're having trouble with your Honeywell Ultrasonic Egg Humidifier.

Q: Mine will not produce a mist after a couple of uses. The mist only comes up half way. It is clean and on correctly
submitted by Dani - 12 days ago
A: Thank you for your question. W're sorry to hear your Honeywell HUL5345 Cool Mist Humidifier is not misting properly. If the mist only rises halfway, it may be due to mineral buildup or a misaligned water tank. We recommend soaking the nebulizer as instructed in manual, and to extend the soaking longer than 20 minutes. Be sure to rinse and dry thoroughly before use. If you have further questions or need assistance, please contact our team at SocialSupport@helenoftroy.com. We're happy to help!

Too Noisey
It’s very careful and easy to clean, however it’s too loud at night. Would not recommend for a bedroom. Fine for during the day living spaces

Only works if on Med/High
I had bought one of these models a couple years ago and have had a good experience. I decided to get a 2nd one to keep permanently in my child's room during the winter. Of course, the brand new one has issues. It won't turn on if plugged into an extension chord, so I plugged it directly into the wall outlet. While it did turn on, it will only push out mist if it's turned on halfway or higher, which produces TOO much mist for the size of the room. It's useless to me if I'm not able to run it on low, so I'll have to return it. What a pain.

Not quiet and very messy
The good: it's attractive, live customer service humans are easily reachable. The bad: though the Honeywell website states 'ultra quiet' it is not. The fan is quiet but there is a constant sound of running water, like dribbling into a basin. More bad: you cannot remove the tank and fill it without a watery mess. It drips from the bottom and when you lift the tank from the base. When you invert it to fill, it drips from the top. Messy every time. Combine this with the numerous reviews citing operational failure, this is going back. The overall rating here is inflated by the Influenster rates, which are all glowing.

Slim and easy!
[This review was collected as part of a promotion.] I really liked the humidifier at first.. simple, perfect for any space, very quiet, etc. Until when I went to go fill it up again, there was a bunch of sitting water that would make a bigger mess for me! I keep using it just sucks the mess I have after!

Sets off my air purifier
[This review was collected as part of a promotion.] I got this humidifier free for review. We've placed it in the living room, which is the largest, driest room in my apartment. While it's been helpful to have, the humidifier sets off my air purifier for some reason. We have them placed pretty far apart, but it still sets it off! We plan to move the humidifier to another room in the future. Just be aware that this can cause other appliances to react to it!

Stopped Misting After 3 Days
I really liked that this humidifier has a compartment for essential oils — that’s a great feature and makes it versatile. Unfortunately, it started having problems after just a few days. The unit was noisier than expected, and then the fan suddenly stopped working. While mist was being made, it no longer pushed out, making the humidifier ineffective. Disappointing experience for something brand new.

Didn't last long
It was a nice quiet humidifier when we first got it. Worked smoothly for about 3 weeks. The fan started making a grinding sound so I tried cleaning it. It did not stop the sound. I got rid of it.

Compact, Simple & Budget Friendly
[This review was collected as part of a promotion.] This compact humidifier is very quiet and perfect for your bedroom or office. It doesn’t have a filter which I like bc neither do I 😊 jk but for real, no filter means less money. Run time is 36 hours and there’s a tray for essential oils, so you have options. If you’re on a budget and looking for a humidifier, I wouldn’t look any further!

Super effective!
[This review was collected as part of a promotion.] I love how compact this cool mist humidifier is designed. It fits easily on my nightstand, which is great for people with limited space. The design is so sleek and modern, so it's not an eyesore. The adjustable settings allow you to control how much mist you need and / or want. It's actually really quiet when running, which is a plus for light sleepers. I use this so much, especially when the colder months are in full swing and the heat is on in the house or we're using the fireplace as this does an excellent job at adding moisture to the dry air. It's also great when you have a cold and your sinuses are clogged. It's super easy to clean and also includes a cleaning brush that is stored inside the unit, making it easy to find.

Love it!
[This review was collected as part of a promotion.] Does exactly what I need it to do! I live in a desert, so the air is super dry. This really helped my skin feel more hydrated. I also love the essential oil feature! So, not only is the air more hydrating, but the smell is nice too!

💦 Meet my new bedside BFF 💦
[This review was collected as part of a promotion.] Super quiet (perfect for sleep), runs up to 36 hrs, and no filter = no extra cost 🙌. Compact design with an oil tray for a little spa vibe. 👎 Downsides: no auto humidity control + cleaning takes effort. Best for bedrooms or offices, not huge spaces. ✨ Verdict: Easy, quiet, and budget-friendly pick if you want a simple humidifier that just works. I primarily use it to sleep with or with essential oils and love it!

Nice!
[This review was collected as part of a promotion.] This is a great humidifier. It's ready to use straight out of the box - just add water and plug in. I love that I'm able to adjust the amount of mist. I wouldn't call it the most "upscale" looking. But it doesn't look too cheap eithet.
