Q: 2 Years ago someone some stated that a "plastic" smell was emitted from this humidifier. Does this unit, now in 2022, still emit a bad smell when running?

submitted by BJGA4 - 4 years ago
  • A: Thank you for your inquiry. Occasionally, new units can have a "plastic" smell from the plastic that the units come wrapped in. If you place the humidifier into a well ventilated area for a few hours, this will allow the smell to dissipate. If you have any other questions please do not hesitate to contact our consumer relations team by emailing us at SocialSupport@helenoftroy.com. Thank you.

  • A: I just received my unit yesterday and can confirm that it does have an absolutely terrible stench. It was so bad that my roommate down the hall started yelling in disgust and asking what that smell was. I took it outside today and ran it on high for a couple hours but that did not help. I just put it back outside to run for longer, if I remember I will come back with an update.

    submitted byRyan - 4 years ago
  • A: mine had it for a few cycles then stopped . It wasnt terrible, obviously not pleasant but not a deal breaker . I dont like to smell chemicals but for the limited time it did it i felt like it was ok

Q: I just bought one of these today. When I started running it, the humidifier put a "plastic like" smell into the room. Will it continue to do this or is this something that should go away with continued use?

submitted by PS - 6 years ago
  • A: Thank you for your inquiry. Sometimes a new unit can have a plastic smell from the packaging. We would advise airing the unit out for a few hours in a well ventilated area and this should get rid of the smell. If you have any other questions please do not hesitate to contact our consumer relations team by emailing us at SocialSupport@HelenofTroy.com. Thank you.

  • A: Mine has continued to emit the smell, which is no doubt toxic, and I would recommend against purchasing this humidifier. They told me to run it for 12 to 24 hours straight on high power, which I had already done (I've had it a little more than a week) but did so again, and it didn't clear up the problem as they said it would. Absolutely unacceptable and probably dangerous to your health.

    submitted byWillE - 5 years ago
  • A: I wish I would have read these before I purchased it. I have been running mine for weeks now and the horrible chemical plastic stench will not go away. It angers me to see the reply about it being the plastic that it is wrapped in and don't want anyone to be fooled by it. The smell is coming from the unit itself and it's obvious. I took it apart and washed it and it did nothing. I'm very angry as I've always bought Honeywell and now I have to find a new humidifier brand.

    submitted bySassy9609 - 4 years ago

Q: When I look up this humidifier on the Honeywell site, it says it’s compatible with use of the protec cleaning balls. But a tech support person answered someone else’s question below saying they were not compatible. Which is it?

submitted by VLM - 10 months ago
  • A: Thank you for your inquiry! The Protec cleaning cartridge is designed for use with cool mist humidifiers, so it is not a recommended accessory for the Honeywell HWM845 Warm Mist Humidifier. We apologize for any confusion this may have caused. For further assistance, please feel free to contact us at SocialSupport@helenoftroy.com. We're here to help!

Q: how hot does the humidifier get

submitted by COOL guy - 3 years ago
  • A: Thank you for your inquiry. The heating element gets got enough to boil water. However, the plastic is made to transmit heat poorly, meaning the unit will not get very hot. However, it will still be very warm while running and we do not advise trying to move the unit while it is running and to let it sit for at least 15 minutes once it is turned off before moving it. If you have any other questions, please do not hesitate to contact our consumer relations team by emailing us at SocialSupport@helenoftroy.com. Thank you.

  • A: I've noticed my humidifier boils if I put on the highest setting and is HOT. Is this normal or should I always set it in low.

    submitted byErin A - 25 days ago

Q: What is the size of the tank?

submitted by Me - 4 years ago
  • A: This tank is a little bit smaller than one gallon. It is maybe 9/10 of a gallon. I tried 3 times to fill it from a one gallon bottle of water, and 1 gallon of water never fit in this tank.

    submitted bydn - 4 years ago
  • A: Thank you for your inquiry. This humidifier holds 1 gallon in the water tank. If you have any other questions please do not hesitate to contact our consumer relations team by emailing us at SocialSupport@helenoftroy.com. Thank you.

Q: what type of water do you use

submitted by region - 5 years ago
  • A: If you use distilled water, it will not work at all. It BOILS the water and it gets very hot, so my whole house smelled like chlorine. I loved this machine except for that, and returned it.

    submitted bydn - 4 years ago
  • A: Thank you for your inquiry. You can use regular tap water with this unit. You can also use, or mix in, distilled water to reduce the mineral content of the water. If you have any other questions please do not hesitate to contact our consumer relations team by emailing us at SocialSupport@helenoftroy.com. Thank you.

Q: Can this be refilled from the top with a pitcher or do you have to pull off the whole container and turn upside down to fill it?

submitted by OurMedGuide - 7 years ago
  • A: You must pull it off and turn it upside down to fill it. However, it has a great built in handle, very large easy open cap, and holds less than 1 gallon of water. So I found it very easy to fill.

    submitted bydn - 4 years ago
  • A: Thank you for your inquiry. This is not a top fill model. You must remove the tank from the unit in order to fill it. We hope this is helpful. Please do not hesitate to contact us if you have any questions. We can be reached by emailing SocialSupport@kaz.com. Thank you.

Q: My humidifier has been running HOT the past day or so and wondering if that's normal since it's supposed to be shooting out warm air. Never once experienced water boiling where the motor is HOT. It's in my kids bedroom so I don't want it to be a hazard.

  • A: Thank you for your inquiry. We're sorry to hear your Honeywell HWM845 Warm Mist Humidifier is running unusually hot.

Q: Hi , can we not descale this unit? What happens if we don’t descale? Thank you

submitted by Hsing - 8 months ago
  • A: Thank you for your inquiry. Regular descaling of the Honeywell HWM845 Humidifier is important to maintain optimal performance. Without cleaning, mineral buildup can affect mist output over time. We recommend cleaning the humidifier weekly for the best results. If you need further assistance, please feel free to contact our team at SocialSupport@helenoftroy.com.

    Terrible. Works 5 minutes and then shuts off, the red light comes on.

    I purchased this because I liked how simple it was. I wanted something easy to use and clean. I read the directions for care before setting it up. Did everything it said to do. I filled it with distilled water, and 5 minutes into running it and it shuts off and the red light comes on even though it is completely filled. I emptied the tray, and rebooted it about 5 times and it keeps happening. It is broken and unusable right out of the box. I will be returning to the store. $40 is too much money to keep something that has so many problems when it is brand new.

    [This review was collected as part of a promotion.] 10/10!! The Honeywell Humidifier worked perfectly! I will say i smell the difference in the air in my house especially using eucalyptus oil for the inhalant. I highly recommend if you are sensitive to dry air and or the humidity is off in your atmosphere. I will continue to use this! 1,000%

    Quiet, effective, and easy to use!

    [This review was collected as part of a promotion.] I love this Honeywell Filter-Free 1 Gallon Warm Mist Humidifier! It’s whisper-quiet and the 1-gallon tank easily lasts through the night. The warm mist keeps the air in my room comfortable and helps with dry skin and stuffy noses. But my favorite thing is that it’s filter free. Replacing filters is such a hassle for me I often end up donating my old humidifiers and buying new ones, so this is a resource and money saver.

    Easy to use!

    [This review was collected as part of a promotion.] This humidifier is perfect for a small room and is super easy to use. It has two settings and also the option to add essential oils, getting by rid of dry air and smells at the same time. I wish that it produced a little more vapor but other than that this is an easily portable humidifier that will be great for the winter months.

    [This review was collected as part of a promotion.] I recently tried the Honeywell Filter Free Humidifier and it works really well. It’s super easy to use since there’s no filter to replace. The mist output keeps the air comfortable and helps with dryness. I’d definitely recommend it for simple, hassle-free humidifying.

    Just what I want in a humidifier!

    [This review was collected as part of a promotion.] I have been searching for a good humidifier for when our winters get super dry, and this one has proven to be excellent! It is silent, aesthetically pleasing, and has more than one setting, which is a great bonus! I love the scent cup that I can add oils or fragrance to! I found that despite the gentle flow of steam, I still had a great amount of scent released. Honeywell has always been a name I thought highly of and will continue to do so!

I would love to have one each room.

    Keeps room comfortable

    [This review was collected as part of a promotion.] This humidifier works so well! It’s super quiet, has great steam output, and keeps the room comfortable without over-humidifying. It delivers impressive output and makes a noticeable difference in our home, especially when anyone in the family is feeling under the weather. It’s easy to refill, runs quietly, and adds just the right amount of moisture to the air to ease congestion, dry skin, and nighttime coughing.

    Easy-fill tank, all-night comfort.

    [This review was collected as part of a promotion.] I started using the Honeywell Soothing Comfort Warm Mist Humidifier this summer because I was waking up with a dry nose, and it really helped. It does exactly what you’d expect, but the design details make it stand out: the large water opening (so easy to fill), a screw top with a good grip even when wet, and a hidden handle on top that makes it simple to carry. On medium, the tank lasts me all night, and it adds moisture without leaving everything around it damp like some humidifiers do. Perfect for a smaller room, and I know I’ll get even more use out of it this winter.

    Humidifier Honeywell – Reliable Comfort

    [This review was collected as part of a promotion.] I have been using the Honeywell humidifier for some time now and can share my impressions. It is very convenient to use, the water tank is easy to remove and fill. Cleaning is also not difficult. The device copes with its function well, as the room quickly feels optimal humidity. It is noticeably easier to breathe, dryness in the throat and skin disappears. It is made of high-quality materials and looks reliable, the plastic is durable and has no foreign odors. It works quietly, almost silently. It does not interfere with sleep at night, so it is suitable for a child's room or bedroom. It has a modern and minimalist look. The black case looks stylish and suits most interiors. Thanks to the transparent tank, the water level is always visible. This humidifier is a reliable and easy-to-use option for the home. It effectively humidifies the air, does not require complex maintenance, works almost silently and looks harmonious in any room.
