Weekly cleaning is recommended to keep your Honeywell Top Fill Warm Mist Humidifier running efficiently.
Warm mist humidifiers can develop heavy mineral deposits on the heating element - also known as scale. This is common in hard water areas where more frequent cleaning may be required.
Before cleaning, turn off, unplug, and wait 20 minutes for the humidifier to cool before cleaning.
All maintenance should be done in the kitchen or bathroom on a water-resistant surface near a faucet.
Empty the Water Tank by pouring from the left side where the arrow indicates. Remove the Top Cover to access the removable components. Twist the Mist Chimney to the left, then pull straight up to remove.
To remove the Heating Element Cover, grasp red latch with two fingers, pull toward front of the humidifier and pull straight up to remove. Grasp the red Float Tab and pull straight up to remove. These components can be placed in the top rack of a dishwasher or included in the cleaning process below.
Next, follow these separate steps for scale removal and disinfecting. Both steps are important and must be performed separately.
Pour 3-4 cups of undiluted white vinegar into the Water Tank where it will drain into the Boiling Chamber and cover the Heating Element. Let it soak for 20 minutes to loosen the mineral deposits on the heating element.
When the heating element is covered in mineral deposits, also known as scale, it is unable to function efficiently and may prevent the humidifier from producing steam.
Replace the internal components if not cleaning in a dishwasher. If Components were added to soak, remove them for access to the heating element.
Wet the bristles of a soft brush with vinegar and gently scrub the heating element to remove mineral deposits, also known as scale. Empty the Reservoir by pouring the vinegar from the left side where the arrow indicates. Pour 4 cups of water into the Reservoir, lightly swish and pour out. Repeat until the smell of vinegar is gone.
Use gloves while performing the disinfecting process. Add one half teaspoon of bleach to one half gallon of water and pour the solution into the Reservoir. Wipe the inside surfaces of the Reservoir with the bleach solution. Soak for twenty minutes.
Empty the Reservoir by pouring the bleach solution out the left side where the arrow indicates. Pour 3 cups of water into the Reservoir, lightly swish and pour out. Repeat until the smell of bleach is gone.
To reassemble, replace the Water Level Float by positioning the red tab in the channel guides and push to secure. Attach the Mist Chimney to the Heating Element Cover and twist to the right to snap in place.
Replace the Chimney and Heating Element Cover and press firmly to secure. Replace the Top Cover
and press firmly to secure.
This was so very helpful and easy to do. Thank you for sharing this!
I wish Honeywell would design a completely flat heating element. Yes, the diameter will have to be larger but it will be so much easier to de-scale.
It’s not that bad. Just let it soak longer. I used a medium bristle tooth brush. Took me about 5 minutes to get all the scale removed
@@jimmy5634 I've been using Honeywells for a decade. Yes, I l soak the humidifier in vinegar for several hours to descale. Could never clean the bottom of the heating element completely. Still, a flat heating element would be an advancement.
*We liked it **Fastly.Cool** so much in the basement, we bought a second one for the main level. The amount of moisture it pulls out of the air is astonishing.*
Really? Its not a dehumidifier!
😂
I love this humidifier guys, just bought a new one. I had the older model for a few years, until the heating element got so damaged that it leaked into the electronics below it and damaged it...but it's really a great humidifier. Most important thing is we do not have to keep changing very expensive filters (have one of your other humidifiers that need an E filter, along with a protec which is so expensive - costs as much as a new humidifier to operate it in winter).
Question: always had an issue with cleaning the heating element, it's such a hassle frankly. Water is not that hard here in Quebec i think, but still I have accumulations. I know you show cleaning it with a soft brush, but isn't there some other sort of tool one can use that make it easier? It's extremely hard to reach the lower part of the heating element especially with a brush...
Hey Antonio. Thank you for your inquiry. We can only advise using a soft brush, such as a toothbrush, to gently scrub the surface of the heating element. However, we may recommend using distilled or filtered water with your humidifier to reduce scale buildup. If you require any additional assistance, please reach out to us by emailing SocialSupport@helenoftroy.com.
It's a bitch to clean the heating element. White vinegar and a strong bristle brush, along with many hours sitting in the vinegar. I clean mine once a week.
What holds the float in place? I found mine floating in 8 inches of water.
I am about to buy this product? Can someone kindly tell me how frequently do you guys clean it? Thanks a lot!
The heating element cover DOES NOT come off this easy. I've yanked on that thing like crazy it it doesn't move. Could there be something blocking it?
Thank you for your inquiry. We'd like to look further into this to help. Please reach out to us by emailing SocialSupport@helenoftroy.com for assistance.
I'm curious, is descaling necessary or need to be done as frequently when using distilled water? I don't see any scaling when using distilled but I still do the process.
Hey itazuranakisu. Thank you for your inquiry. For best performance, we do advise descaling and disinfecting the humidifier once a week, as outlined in the owner's manual. We hope this is helpful. If you require additional assistance, please contact us by emailing SocialSupport@helenoftroy.com.
Who can afford distilled water?
@@jimmy5634I have a water distiller and distill one gallon daily for my humidifier. Buying it wouldn’t be worth it.
@@RockyTrifari No kidding, this is costing me a fortune using 4 liter bottles of distilled water. Did you buy a machine that distills your water? If so what brand do you recommend?
@@Gamelover11 I bought a distiller on Amazon and it was the best investment ever!!!! I think it was $50-100 and I use it once daily to fill my humidifier
I’ve been using distilled water. After two weeks, the heating element is covered in scale. Way too much work, this is going back.
If we only use a couple times a week, or per month, weekly isn't needed. More accurate info would be, after how many USES should we clean?
Hey Danielle (6Hypnone). Thank you for your feedback. We do advise cleaning the unit weekly as outlined in the owner's manual. Please also follow the cleaning instructions when the humidifier will not be used for at least one week, or at the end of the season. We hope this information is helpful. If you require additional assistance, please email us at SocialSupport@helenoftroy.com.
Can Vicks Vapo Steam be used with this unit? I don't want to use essential oil.
Thank you for your inquiry. Yes, you may use Vicks VapoSteam in this humidifier's essential oil cup. If you have further questions or need assistance, please reach out to us by emailing SocialSupport@helenoftroy.com.
I just bought mine and I have been trying for 15 minutes to remove the mist chimney but it will not turn! So infuriating!
I brought a new one. It is not working after one minute. The reset light is blinking. What is the issue? Do I need to return the item?
Thank you for your inquiry. We apologize for any inconvenience this may have caused you. We'd like to look into this further to help. Please reach out to us by emailing SocialSupport@helenoftroy.com for assistance.
My humidifier has the blue check mark on constantly and it not work anymore. I’ve tried unplugging for 20 mins and everything. Please advise. I’ve only used it for a week
Hey Renan. We're sorry to hear you had this experience. We'd like to help with troubleshooting. Please reach out to us by emailing SocialSupport@helenoftroy.com.
I have the exact same problem!
Same
Did you get this fixed?
Is it ok to use bar keepers’ friend to remove the scale? (It is also acid）
Thank you for asking first. We cannot advise using any other chemical other than white vinegar to descale the humidifier. If you have any other questions, please email our support team at SocialSupport@helenoftroy.com and we will be happy to assist you.
Is it possible to use citric acid instead of vinegar? Also is it necessary to use bleach with each descaling?
Thank you for your inquiry. We do not advise using citric acid to clean the minerals from your unit. We do advise going through the disinfecting process after the descaling process each time for the health of the humidifier. If you have any other questions, please email us at SocialSupport@helenoftroy.com.
Manual said should take about a minute to heat and run. I’ve been waiting for about 5 minutes and still not running. Suggestions?

Any idea when you will be getting more of the ALL BLACK model for sale in Canada? This is the only color scheme I want, all black, not the almost all black with grey top.
Hey Andrew. We'd be happy to assist you with your inquiry. Please reach out to us at SocialSupport@helenoftroy.com for assistance.
@@honeywellpluggedin9834 sent! Thank you
@Honeywell plugged in, just bought this ran once and the reset light is on. The light will not go out, this is disappointing after only one use. There is no scale buildup. If this product has to be cleaned after every 1.5 litres of water, I’d say it is not user friendly.
Do you guys refurbish and repackage them for sale at retailers? I got one of these of a similar model a few months ago. And when I opened it there was like a hockey puck shaped chunk on top of the heating element. And because of the shape I thought it was supposed to be part of it. But the more I used it, the more the chunk started breaking down until it started to crack. Then I started get the reset light a lot. The manual to troubleshoot didn't show a lot of detail. It wasn't till I watched this video that I realized there was something wrong. Some how it came with a huge chunk of minerals on it already. The box wasn't one that was returned cause it wasn't resealed.
We're sorry to hear you had this experience. To confirm, we do not sell refurbished or repackaged products. If your product was sold as new but appears to be used, we'd like to look into this. Please reach out to us by emailing SocialSupport@helenoftroy.com.
Ours had the same problem. I think they may test it with tap water at the factory causing the chunk to develop. The water in China may not be the best to begin with, let alone for testing the unit. We use distilled water only. No problems after switching.
Just got mine yesterday brand new and had the same problem.
Alternatives to bleach? I stay away from bleach
Hello Danielle. Unfortunately, we do not suggest anything other than a bleach solution when it comes to disinfecting this humidifier. If you have any other questions, please email our support team at SocialSupport@helenoftroy.com and we will be happy to assist you.
I don't like it. Had mine 1 year. I am fingdind it very difficult to remve the heating element cover. I have msde several attempts all to no avail. Can't figure it out. Seems i will have to throw this one out and buy something simpler!
vinegar does a very poor job of removing the scale even with brushing. This is after only 1 week of 8hr/day operation. Way too much trouble. It looks like I will be switching to distilled water or another type of humidifier
Hey Robert. We apologize for any inconvenience you have experienced when cleaning this humidifier. The following link has video instructions on how to clean your humidifier: th-cam.com/video/rMMS8Ge8fmc/w-d-xo.html Also, please note, if you have a lot of mineral buildup on the heating element you can soak it with vinegar longer, such as several hours or over night. This will help to loosen any mineral build up. You may then gently scrub the heating element with a soft brush to remove the mineral deposits. We hope this is helpful. If you require additional assistance, please reach out to us by emailing SocialSupport@helenoftroy.com.
I run the humidifier for 20 minutes and the scale falls right off
Just got this yesterday brand new and it doesn’t work!!😡😡 I did all the trouble shooting!
That is not what we expect from our humidifier. Please email us at SocialSupport@helenoftroy.com and we will be happy to look into this and help make it right.
I know I’m a BIG BABY…..Have to make sure the sinuses are CLEAR.
DON'T WASTE YOUR MONEY ON THIS TRASH. The humidistat does not work properly. I've had 2 and sent both back. Awful product
We apologize for any inconvenience this has caused. We'd like to look further into this to help. Please contact us by emailing SocialSupport@helenoftroy.com for assistance.
@@honeywellpluggedin9834 Too late. I no longer have them. I can understand if one unit was faulty but not 2, especially with the same problem.
Watching her stick her arm in the humidifer to replace the water level float really wasn't very helpful.
why the hell do moron product designers not make the heating element REMOVABLE like the other pieces? no one can reach down into the unit to scrub this thing we either have to half-ass it or disassemble the whole unit and worry about the seals. i clicked this video excited i might actually find a sane warm mist humidifier, but no, this one is just as stupid as the HWM340 which is also impossible to descale without disassembly. the HWM705 is better since the upper chamber comes off, but it has no humidistat!
Hey Joshua. We're sorry to hear you feel this way. We will share this information with our team. If you require assistance, please reach out to us by emailing SocialSupport@helenoftroy.com for assistance.
@@honeywellpluggedin9834 plus, you did not answer the question about using distilled water!!!
This is too much work. I’ll just buy a new one.
Wow
