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: 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

    submitted bytb - 3 years ago
  • 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

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 - 4 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.

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 - 8 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: 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: 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.

    submitted byManufacturer Tech Support - 7 years ago
    Brand expert
  • 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

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

submitted by Hsing - 6 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.

Q: How can I clean this? When I put it away for the season and come back, it has a nasty orange film on it.

    [This review was collected as part of a promotion.] This humidifier works great! It’s pretty quiet and very easy to clean, especially with the parts being dishwasher safe. The tank is easy to refill and replace into the machine too. I also love that you can put essential oils into the little reserve area. In the winter or during allergy season it would be so nice to have warm mist of peppermint in the air.

    [This review was collected as part of a promotion.] The Honeywell Soothing Comfort Warm Mist Humidifier has been such a relief during dry weather. I started using it because the dry air was leaving my skin feeling tight and my throat scratchy at night, and it’s made such a difference. It produces a gentle warm mist that adds just the right amount of moisture without making the room feel damp or heavy. I notice I sleep more comfortably, and I don’t wake up with that dry, irritated feeling anymore. My skin feels less dehydrated too, which is a huge bonus. It’s also quiet and easy to use, which I really appreciate. The design is simple, and cleaning it hasn’t been a hassle. Overall, it’s a great choice if you’re looking for a reliable humidifier to ease dry air discomforts and create a cozier environment.

    [This review was collected as part of a promotion.] Honeywell Humidifier will be a welcome addition for this coming winter season! Our house gets dry as soon as we turn on our heat. Then come the dry scratchy throats and sometimes even nosebleeds due to the dry air. The humidifier takes a couple of minutes after turning on to start steaming. It’s a warm mist and I can also add essential oil to the top of the tank! It’s going to spend the season in my bedroom so that we can sleep more comfortably and it’s so quiet I won’t even notice it on. I love that there’s no filter required and it was easy to clean after using. It worked so well I plan on getting one for each of my kids rooms! I received this item complimentary for the purposes of testing. Key features: Easy grip tank handle Auto shut off Essential oil feature Wide tank opening Quiet operation Key benefits: Dry, itchy skin relief Naturally moisturizes Helps reduce static electricity Helps hydrate nose and throat

    [This review was collected as part of a promotion.] I received a complimentary Honeywell Filter Free 1 gallon Warm Mist Humidifier in exchange for my honest opinion. This humidifier is easy to fill and empty. This model functions quietly so you won't lose any sleep. I love that this has an essential oil cup so you can add whatever relaxing oil that you prefer. It takes just a few short moments for the device to warm up and then it emits a super fine light mist into the air. It also has no expensive filters to replace. This is a perfect way to add moisture to the air. This has been a blessing for me while dealing with active allergies. It helps with my dry throat and stuffy nose, it makes the air feel more breathable.

The Honeywell humidifier has been such a great find. One of my favorite features is how easy it is to add essential oils. The warm mist really helps the scent spread beautifully through the room, creating a calming, cozy atmosphere — perfect for bedtime. It’s not just about comfort either — it’s helped with dry air, stuffy noses, and even my skin feels better. It’s one of those small things that makes a big difference for the whole family.
