For arid climates or the dry cold days of winter, running a steam humidifier indoors often protects the inhabitants' skin from chapping or itching, allows stressed lungs to breathe with comfort, and infuses moisture into the room to the benefit wooden furniture, upholstery, and houseplants to prevent them from becoming brittle or parched. Honeywell created their Quick Steam Warm Moisture Humidifier for all of these purposes and more, enhancing a room's humidity in record speed. Best suited for rooms up to 1400 square feet in size, the humidifier's heater is crafted in stainless steel for quick heat production and trouble-free cleaning. The compact humidifier outputs 4 gallons of warm steam for each full tank of water. This humidifier offers users a timer function for running the unit for preset periods, ranging from an hour to the maximum 18-hour setting. Digital controls and the easy-to-read LCD screen enable users to alter or monitor current preference settings. A medicine cup allows users to run the humidifier as a vaporizer for stuffed noses, sore throats and other respiratory illnesses. An automatic shutdown feature reduces safety hazards. Humidifier water should be changed frequently and the tank washed well each week to prevent bacteria, mold, and other impurities from developing, though the heating process should kill many of these unhealthy particles. As with any electrical home device, read all manufacturer guidelines and instructions prior to use. This humidifier measures 15.55 by 14.57 by 10.24 inches and weighs 6 pounds upon shipping. --Jessica Reuling

 Best made Humidifier on the market February 24, 2008

I am a skilled Commercial/Industrial Equipment Repair Technician and I can tell you this is a well built unit. I have answers to all the questions in this message area and to all the issues some people are having with simple user problems.
The Warm mist is the best to buy for the winter, it puts out the most humidity and helps to warm the house. It doesn't have bacteria like cold water units which need filters and are best used during summer months to help COOL the room.
Like all equipment there is maintenance, and some required maintenance is well worth the comfort and relief you get from the dry air in the room during the winter months when the humidity levels drop down into the teens!!
Whenever water is boiled any calcium, iron, and air you have in your water will separate from it. Same here, if you have hard water calcium will collect in the bottom of the water reservoir. Honeywell knows this and has made this unit capable of being used in such situation. If you have very hard water you can use the mineral pads, some supplied, to help absorb the minerals.
Water softeners help to remove most of the calcium and iron that makes your water hard. You do not need to use the mineral pad, the unit will operate better without it!! Use it in situations if you have very hard water only. Most of the extra noise is when air gets trapped below the pad because the air holes are blocked during use, and it builds up pressure and pops.
Do not clean the pad and reuse, it shreds and blows up blocking the air holes in the 2 layer pad. The holes must line up and not get crossed like closing a valve trapping more air in the bottom of the tank.
As the Humidity in your home drops the moisture in everything in your home dries up, the wood, furniture, walls, and floor, so it will take some time (about 1 to 2 weeks) until you get all the moisture back into everthing. Water levels below 40% are considered to be dry, and 30% and below are very dry. You can get nose bleed and headaches below 35%!!Ideal levels are 45 to 50 percent. In the winter it is harder to get levels up because you have constant drying from the weather and your heating system. Dry mouth and sinus relief can be noticed above 40%. I recommend a unit for each floor. You may need to fill it once a day on low, and twice a day on high, hence the different output levels. Whatever it takes to achieve your desired humidity level.
So the water, type of heating, weather, and construction of your home are factors effecting the overall performance you will get in aquiring your desired humidity level. This unit puts out up to 4 gal a day, that is awsome!! The more it is used the more you will have to clean it depending on how hard your water is. Remember a water softener will help most situations.
All in all this unit will handle the job, it's stainless steel heating plate is easy to clean, just pop the unit apart, brush and rinse the parts off, it all washes well in the wash room. Only the calcium thing is a problem for those who have very hard water, but in most cases a water softener is used and should take care of the problem.
Use the mineral pads only if you have a hard water problem, turn the output level to the low setting after the humidity level is achieved. Check the mineral level in the reservoir when you fill the tank, you can see the water when you lift the tank off, if the water is dirty, it needs to be cleaned soon (every 1-2 weeks, takes 5-10 minutes). The unit will shutdown if the water is too dirty, cool heh!!
I recommend this unit over any other brand out there, don't mess with the ultrasonic nightmare units, I hear they are a real headache and spit dirt all over the place, the maintenance it high too, plus the filters are expensive!!
Very pleased March 19, 2006

I bought 2 of these, after a bit of comparative analysis. I have been very pleased. They are quiet and very effective, plus easy to refill. Note: I use distilled water to eliminate cleaning problems.
excellent warm mist humidifier -- you will not be sorry! January 5, 2007

I am extremely pleased with this humidifier. I much prefer warm mist models to cool mist models due to the quiet operation and soothing mist. I recently had to replace my veteran warm mist model that has since been discontinued and in my two year search I purchased (and returned!) nine (yes, nine) different warm and cool mist models from various manufacturers before I found this one. I was absolutely disgusted with what is on the market, even at four times the price. Cool mist ones that promise to be "ultra quiet" sound like jet engines; ultrasonic models produce unbelievable amounts of fine white dust even with new water treatment technologies that claim to reduce mineral output. Warm mist models are especially hard to find (forget it if you want digital controls) and tend to have very low output.
I am very pleased to say that the HWM450 lives up to my very high standards and I'm quite surprised to see some of the poor reviews here. I've had mine for about 3 months. I knew this was the one when I first unpacked it. I was so accustomed to the poor design and flimsy construction of the other models I've owned that I was literally taken aback when I disassembled it. The technical design of this humidifer is absolutely beautiful. The heating plate is stainless steel and has a large surface area. A heavy plastic baffle/deflector sits inside the unit over the heating plate in an upside-down cone fashion to create an enclosed steam chamber which enables it to operate quietly and have surprisingly high output on its highest setting. Unlike other models, the steam chamber design is brilliant because it clearly traps as much heat as possible near the heating plate in an effort to keep energy use reasonable. It has the additional benefit of helping to muffle the sound of the boiling water.
The mineral absorption pads do a reasonably good job of controlling mineral buildup. I live in a city with relatively hard water and I find I need to clean the unit and change the pad once a week. Get some cleaning solution designed for humidifiers (or white vinegar works, too) and cover the heating plate with it. It helps to slightly elevate the opposite end of the unit to encourage more of the cleaning solution to stay on the plate instead of draining into the rest of the tray. Let it soak for 30-60 mins and then use an old toothbrush to brush off the softened minerals. If it doesn't get clean on the first soak, repeat. You should be able to get it spotlessly clean without scrubbing.
Pros:
- Quiet, like you'd expect from a warm mist model
- Produces more humidity than any other model I've tried
- Three levels of humidity output
- Digital controls
- Hygrometer (humidity meter) that ACTUALLY WORKS ACCURATELY and is not tricked by the humidity generated by the unit
- Timer feature could be useful if you're not using it in the winter
- Doesn't produce any white dust like ultrasonic models do
- Sturdy construction; obviously well-designed
Cons:
- Mineral absorption pad needs to be replaced regularly (I've found weekly) for optimal operation
- Needs more cleaning than cool mist or ulatrasonic models (cleaning is relatively painless, though -- see comments above)
- Water tank could be larger, although you'll get 20-24 hours out of it on the normal output setting once you're maintaining the desired humidity
Again, I can't recommend this model enough.
I love this humidifier! August 31, 2006

This humidifier was perfect for taking the dryness out the air and worked well even in my large living room! I would definitely suggest this to anyone looking for a high quality unit that does the trick!
I can't sleep without it! November 6, 2006

I really like this product. It really heats up fast and doesn't make very much noise. I have gotten so used to the noise it makes, I can't sleep without it. I don't have my burning sinus problem anymore. I moved to the desert from California and this has made a positive impact on my adjustment.
