Very Good - High Tech HumidifierOct 30, 2005
By LaZeR "lazer30"
Don't mean to be a humidifier geek but researched A LOT of them before settling on this one so maybe the reviewer before me should have given it another chance before returning it. At night if you set it to low there is no loud gurgling/boiling noise, and if you have the tank reasonably full there are never any distracting noises. Also wanted a "pure" clean mist, easy maintenance, and of course effectiveness. I liked the features, functionality, and design of this one over the others, so I paid a bit more and got it even though the size and all the features are gravy as far as I'm concerned.

What sets this system apart from the others is the following: A large LCD display shows the current humidity level and there are three separate digital controls - output level, moisture, timer - each of which you can set exactly. What makes this efficient is you can DIGITALLY set the humidity to your EXACT preference - anywhere from 25 to 65. If you want it to shut off when you leave for work, set the timer - 1 to 18 hours. A four gallon output and 1400 square foot range makes it convenient.

It's warm mist so no filters ever need to be puchased but in due course you'll need to get new mineral pads which sit over the stainless steal heating element. I think Honeywell has or is getting a patent for the heating element. Humidifiers are almost always used during winter so why did they invent cool mist ones anyway?

It looks good, works well, is compact, and so far satisfied with the operation and paying a bit more for this model. Maybe Honeywell is trying to be serious about the quality of its products *shrug* who knows. The only non-critical issue is a light indicator should turn on when the desired humidity level is reached but it doesn't. Don't like when I buy something and even the simplest stated feature doesn't work, but in this case will let it slide as no other functionality is affected.

Bottom line - even if all you need is a simple, small humidifier, with few features, you might be happier getting this one instead.

UPDATE, November 28, 2005
Reviewer: B. Ahmed "lazer30" (Mars) - See all my reviews

Just an update to my previous review. Exchanged the unit since the indicator was not turning on when the desired humidity level was reached. Seems it was a burnt out bulb. When the desired humidity is reached the indicatior does in fact go on, the humidifier stops discharging, then when the room falls below the desired humidity level the unit starts back up again.

Another thing: it's a good idea to clean this unit regularly - perhaps once a week. I read another guy's post where he used CLR in the cleaning routine. Might try that as the heating element can never be cleaned to look like brand new without using something. Honeywell writes in the manual there will be some stains left on the heating element but this should not affect performance.

Fairly pleased so farDec 17, 2005
By Reviewer
I researched humidifiers extensively before settling on this one by Honeywell. I've had it a week so far, and here are my thoughts.

It is very well made, easy to assemble, clean, and digitally program. In four days my face went from dry, cracked flaky and bumpy to buttery soft, smooth and bump-free, which to me is a priceless benefit. I have extremely parched sensitive skin and live in a condo with forced hot air heating, and figured I needed to invest in a humidifer but never got around to it until now.

So why the four star rating? The first two nights the unit reflected 20% humidity in the house and couldn't seem to raise the moisture level beyond that. It did not make a dent in the environment or my skin. The third night it rained, and since then the unit has been getting closer to hitting the 55% humidity setting I have it on, but so far hasn't gotten there yet. Not sure why. I have just under 1200 sq feet and it's a four gallon output which is supposed to be adequate to humidify my living space. It's been sunny outside for the past few days, and my fear is that if it doesn't rain again soon and the temperature drops, the humidifer may not be able to continue to raise the indoor humidity level. But perhaps the humidifying effects will turn out to be cumulative if I run it every night while sleeping as I've been doing.

Another con - the water only lasts a couple of hours, not the whole night through, on the high setting. I will have to experiment with the medium and low ouput levels as this seems the likeliest culprit.

A word about the noise - does not bother me at all and I am extremely sensitive to and easily irritated by various noises. I find the quiet bubbling sort of sound rather soothing actually.

I would strongly recommend the unit for people with dry parched skin. If performance falters, I will update this review.

A final note on what I learned while researching humidifers, for what it's worth -

supersonic units apparently have a problem with spewing white mineral dust into the atmosphere; cool mist is a bad choice for the winter months and no one is sure why you'd need a humidifer in warmer months, so the reason for making these is a bit of a mystery; evaporative types are a playground for bacteria and a pain to keep clean; and warm mist seeemed the easiest to clean and operate (which is why I selected this model).

1 Month Update - Still going strong. Easily reaches desired humidity level with one of the doors to my master bedroom shut. Note about cleaning - in the manual they say to set the water tray aside and fill it with a cup of vinegar. What they MEAN is - dump any water out of the water tray, put it back in the unit, and THEN fill it with vinegar. The cleaning instructions leave a lot to be desired. The way it's stated in the manual, since the water tray is an empty funnel on one side with a shallow tray on the other, there is NO capability for it to hold the vinegar unless you put it back in the unit, which is NOT stated in the manual. They leave you hanging with your water tray "set aside". Honeywell- take note. Learn to write step-by-step instructions correctly, especially in areas where you note that adherence to them is critical!

Also, NOWHERE in the cleaning manual does it say to rinse the heating pads thoroughly. I find that doing so keeps them clean, white and fluffy. This is another major oversight in the manual's instructions on cleaning. They were just plain careless at guiding you through the process. Also very important - if after a cleaning your unit won't start - it may be because the scent of bleach or vinegar is still clinging to the parts. This has happened to me. With additional heavy rinsing, the unit operates again with no problems. I run it at nighttime when the air is dry, and have been cleaning it every other week. The longer the vinegar stays in the water tray, the more the gunk on the heating element lifts. Note to K. Seeley - that reviewer more than likely has extremely hard water. Try rinsing the heating pads for longer life.

A very temperamental, fully-featured humidifierMar 21, 2006
By Paul Stuart ""...also I'll brush my teeth and remember to turn off the stars at night and put the hyena out." ERN"
Akin to other reviewers, I performed extensive research on humidifers before concluding on the HWM450. A Consumer's Report 'Best Buy' + strong feedback ratings on multiple price comparison sites led me to what appeared to be an 'obvious' purchase on Amazon.

Egads. As the old adage goes, you get what you pay for.

To be fair, I love the multiple output settings, humidity on/off feature, not to mention the handy, hourly shutoff option. Moreover, a big water tank allows for 1.5 nights of full use without a refill. Finally, the HWM450 is also extremely quiet, and does quite well with Vicks Humidifer Vapor Fluid poured into its medicine cup.

The downsides...equally as obvious. The digusting yellowish-orange, mineral deposits + algae buildup after only 3-4 days of use are both eyesores and difficult to clean. The humidifier's 'mineral reservoir' [actually] promotes this buildup by storing this gunk in cavernous channels until emptied. Worse of all, the gunk burns on and into the heating plate rather quickly in an almost cement-like fashion. (Why the HWM450 doesn't burn off/liquify more of these deposits as part of its humidification process is beyond me. Lower tier, Honeywell humidifers operate under this premise.) Related, the mineral deposit pads become equally tainted rather quickly.

The good news is, the HWM450 is easy to clean...if you know how. Trial and error produced the knowledge -- alluded elsewhere in reviews -- that the cleaning pads can simply be rinsed clean with cold water (don't waste your money on new pads). Second, the mineral reservoir can easily be rinsed clean, likewise the humidifier's removable components. The mineral plate is a little feistier. Not feisty enough, however, for a 1/8th inch layer of CLR left on it for a good 30 minutes. Breaks everything down for an easy clean/rinse off.

My first HWM450 began to emit a strong burning odor after its first cleaning cycle. I returned it to Kaz (Honeywell's parent company) -- excellent customer service -- who replaced it at no cost (minus my shipping to send it there). The second unit has a buggy hygrometer, echoed by others here who have it stuck on 20 percent.

Moral of the story? If you can get past its shortcomings, a decent short-term humidification solution. I remain on the lookout, however, for a pricier, more reliable unit.

Best made Humidifier on the marketFeb 24, 2008
By Nikola Tesla "Free Energy"
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!!

*** Update 4/23/2011 ***

One of my units started to leak at the heating element silicone rubber seal in Fall 2010. I called up KAZ and they asked me to send in the whole bottom base and they will send me a whole new unit! Looks like they did a design change to the heating element, replaced the flat stainless element with a newer knob style element. I had it almost three years and KAZ stood by their products which means a lot to me. Despite the miner problem design with the flat element in the unit I still like it because it was easy to clean and worked great to moisturize the room. I looked at many and had many different brands, but I still believe Honeywell makes the best for the money.

FYI the new model is Honeywell HWM-450NC, you need to do your own search for it because we are not allowed to post URLs in our reviews on AMAZON.

The newer unit works great, little different to clean, but still have to clean with a tooth brush. Cannot polish it with a scotch brite pad like I did on the old model. I have used the new model all winter long and it worked great.

Good unit for winter drynessOct 09, 2006
By Bruce Carlson
I like this unit best among half a dozen warm stream humidifiers I've tried. It has an ample tank that can last through the night, yet it can pump out enough moisture quickly to cover my family room, even fighting the forced-air heating system (which, of course, replaces a lot of the moist air with freshly heated dry air every time the heat runs. I expect it does a lot better with convective heating systems.) The variable speed, automatic shutdown timer and variable humidistat are all handy (though I wish they didn't need to be reset each time the unit is powered on); and, I like the fact that it actually displays the current humidity reading (as opposed to some units that have a control calibrated only as "more humid ... less humid" and you have to guess what it currently thinks of the humidity.)

Cleaning is easier compared to other warm vapor models I've used (whose heating elements become caked in mineral deposits), though this ease comes at the cost of having to keep spare replacable pads around (it comes with 4, and they last a couple of weeks each, so you might as well order a 12-pack while you're at it.)

Since it does add heat to the air, for summer dryness (I'm in Arizona) I prefer an ultrasonic humidifier. But for winter use, this is my choice.
