Customer Ratings & Reviews

I recently purchased the Honeywell HWM845 Warm Mist Humidifier, and it has become an essential addition to my home. The standout feature for me is the essential oil cup, which elevates the humidifying experience to a whole new level. The warm mist produced by this humidifier is not only effective in alleviating dry air, but it also creates a comforting environment. The addition of the essential oil cup allows me to enjoy the benefits of aromatherapy while tackling respiratory issues. Setting up and operating the HWM845 is a breeze. The control panel is user-friendly, and the essential oil cup is easily accessible for adding drops of my favorite essential oils. One of the standout features of this humidifier is its almost nonexistent noise level. I have yet to hear any disruptive sounds, making it an ideal choice for use in bedrooms or other quiet spaces. It truly lives up to its promise of silent comfort.

I think the Honeywell Warm mist is a great investment. This time of year house humidity needs more moisture. The use of heat and in the days that follow there are 2 reasons I bought it. One is health and it makes breathing easier and bronchitis is out there and it helps in treatment. I have met some. Two moist air holds heat better than dry air . Great value at Best Buy . Note the tank will not over do and no mold will form due to excessive overnight use. Easy to lift and clean. Thanks. Best Buy has restocked.

I do like this humidifier. It's the second one I've purchased because I was not cleaning it properly to prevent scale accumulation. Now that I know (!) I'm pleased. It's important to follow the suggestion for weekly cleaning with distilled vinegar. Otherwise, I'm happy with it.

This humidifier is a powerful little thing! It’s super quiet too which is a plus. I love the auto shut off setting as well. Very easy to use and refill. I like that it’s a WARM humidifier, perfect for fall and winter. I purchased for my plants but it also helps me breathe better.

I absolutely love the Honeywell HWM845 Warm Mist Humidifier! This little machine has been a game-changer during the cold, dry months. It produces a steady, soothing warm mist that makes my bedroom feel much more comfortable at night—and it really helps with dry skin, nasal congestion, and even sore throats. One of my favorite features is the essential oil cup. It’s super easy to add a few drops of oil and enjoy a light, calming scent while the humidifier runs. It’s not overpowering, just the right amount to make the room feel relaxing. I also appreciate that it’s filter-free, which means no extra parts to replace—just regular cleaning, which is easy to manage. The tank lasts a good while (usually overnight for me), and it shuts off automatically when it runs out of water, which gives me peace of mind. It's quiet, efficient, and very easy to use. I just set the dial to my preferred setting and let it do its thing. Plus, the sleek black design looks nice and modern in my space. Overall, I couldn’t be happier with this humidifier. It’s affordable, reliable, and gives me everything I need to stay comfortable and breathe easier at home. Highly recommended!

Works great, easy to clean and runs great. Bought two for each bedroom

Good humidifier, the warm mist is helpful to keep moisture airborn. This model is simple with just two setting options, not a lot of options just low, high and off. No filter keeps this unit simple also. Price was a little high for the features in my opinion.

Winter is here! (hehehe) Oh man can Chicago winters make your nose dry and agitate your sinuses. This was a great buy and goes right along the line of what humidifiers are going for. I like that it has an essential oil cup to assist for scents and other purposes, really easy to remove as well for cleaning. It lets out a decent mist, this is perfect for a small room, our room is a little big but it does the job. Nothing out of this world, easy to refill, great holder for transporting the tank, and easy cleaning. The settings are nice and the auto shut off helps. I would say keep it at the low level if you want it to last throughout the night, it burns quickly through the water at the high setting and you will have to refill the tank. No one wants to get up at 2am to refill a tank.

Works great ! Compact! Easy to use. Quiet. Does its job

Quiet and easy to use, all around a great product.

This is the second humidifier we have purchased. The first one was cool mist and did not meet our needs. We purchased a warm mist humidifier and it provides us the comfort we sought. It is easy to use and treats our large bedroom. It provides us with relief from our sinus issues making for a great nights sleep. I highly recommend this appliance!

Excellent functioning humidifier, and easy to fill. Keeps the large bedroom comfortable.

Works as expected and it's nice that you can also add essential oils as well.

Great warm mist humidifier. Easy to use, add water, & clean when needed. Good purchase. Works very well & quiet. I breathe better & I sleep better. Must have. I also bought the Honeywell humidity monitor. This helps to know humidifier is working well.

Great humidifier . I suffer from dryness in my sinus as soon as the heating season starts . This has prevented that problem for me completely

Not fancy but gets the job done, make note of the room size for it does make a difference in performance..Fairly quite and easy to use. Good basic humidifier.

Is quiet. You don't know it is running. Does the job to keep the humidity in the air to a normal range. I like the warm mist so you're not getting cold air circulating. Lasts for several days before refill. Built in handle is great.

Helped me to sleep better, good product to have in your home.

Actually pretty good - been through a number of these and most break or don't work real well. This one will give a pretty solid 8 hours on high setting and the low setting almost 24. This is great as it is not larger but with the low setting it provides moisture once the high setting has done the job and maintains liquid needing only one refill a day. So far real happy with this and I live in mile high Denver where the dryness is a big winter issue, so this has been ideal.

Last all day number one setting last for 4 to 6 hours on the number two setting only had it for a month after December 20 to January 6. Everything is working fine just needs to be cleaned once in a while overall very good ..
