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.

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

A: I don’t smell anything, and I’m pretty sensitive to smells

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.

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.

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!

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.

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.

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.

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.

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.

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.

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.

A: Thank you for your inquiry. For the Honeywell HWM845 Humidifier, the highest humidity setting is achieved by selecting the High Mist option on the control knob. This will produce the maximum warm mist output for faster humidity increase. Make sure the water tank is full and the unit is placed on a flat, water-resistant surface for best performance.
