Product Description

Amazon.com Review

This top-of-the-line Cool Mist humidifier is a big step up from those old steam-spitting devices. It features a front LCD panel from which you can select the desired humidity. Simply adjust the setting to anywhere between 20 percent and 90 percent (50 percent is recommended for most situations) and set the fan to low, medium, or high. The unit is oval in shape, and because the controls are on one end, it can be operated easily even if placed in a narrow space. (It's 10 inches wide and about 17 inches deep.) The curvy, translucent gray rear tank lifts off easily for refilling, as does the front fan unit for changing or rinsing the drop-in filter. The water tank is dishwasher-safe. --Richard Farr

5.0 out of 5 stars Easy to use and maintain, May 28, 2001
By 
This review is from: Hamilton Beach 05521 TrueAir 3.5 Gal. Cool Mist Humidifier
This product is extremely easy to use, fill and clean. The water tank on the back has a sturdy handle and pulls right up. The tank is completely sealed, so after filling it you can carry it back without risk of spilling anything. It holds enough water for a day or two, which is nice. The filter is easy to change - lift up the front housing and drop it in. The motor is quiet - not silent, but it is in the bedroom and we sleep fine. Dialing a particular humidity is great. It turns itself on and off to maintain that level - you just dial and leave it alone. It keeps our 10x18 bedroom at 50% no matter the weather. Much better than other humidifiers I've used.

October 2004: Replacment Tank. I would like to add that recently, I knocked the water tank against the sink - fairly hard (I slipped) - and the bottom corner of the tank cracked, and was leaking. One call to Hamilton Beach and a new one was on its way, free of charge. Now *that* is customer service.

November 2005: Repurchase. After five years, the old unit was gunked up on the inside beyond cleaning. The instructions say to store it, "completely dry, sealed and in its original box", when not used for over two weeks. I never bothered (who has time for all that?), so it was out in the room permanently for 5 years. Of course, it collected dust and grime on the fan blades and inside the housing. It was not possible to disassemble the unit for cleaning - I tried but it looks like once put together, it was never meant to be taken apart by anyone, not even a technician. With such high-maintenance storage instructions, many owners will have units that stay out and get grimy inside. They really should make it easy to thoroughly clean all of the internal parts.
That said, I purchased another of these units. The new one came with a tank made of a different kind of plastic - slightly more rubbery and not so stiff. Perhaps the old, harder plastic cracked too easily or something. The new tank is ok, but one time after filling it up, the plug came out and I had to sop up a couple of gallons of water off my bedroom floor. I kept the old, hard tank from the old unit and am using that now. It works fine.

4.0 out of 5 stars Performance matches expectation, March 23, 2004
By A Customer
This review is from: Hamilton Beach 05521 TrueAir 3.5 Gal. Cool Mist Humidifier
I bought this humidifier a month ago after much research. So far, it hasn't shown any mechanical trouble. The filter is holding up just fine after 4 weeks, despite daily use. Surely the quality of water in your area dictates how frequently you will need to change the filter. Nevertheless, it is recommended that you flip the filter over (to prolong it's life)when you refill the water. In my case, filter change maybe warranted no sooner than 2-3 months.

The large capacity of the water tank is good enough for 24 hour operation (on quiet setting). I use it all day night long on the low setting and it uses up about half the amount of water in the tank. At first the low setting may seem noisy especially if there is very little ambient noise around you (like when you can hear the wall clocks in your house ticking). But after a few minutes it sounds just like a dull whirring sound that is hardly objectionable. I use it in my bedroom at night and it doesn't disturb my sleep.

It is easy to see the level of water through the tinted tank. The water tank is easily removable when handled vertically. There is no leakage/spilling when you do so. There is a wide fill hole at the bottom of tank for refilling water. There are two problems though with refilling ...firstly the tank is too large to fit under the faucet in the kitchen sink, so you need a jug or hose to fill it up or use the faucet in the bathtub...secondly, the cap on the fill hole is pretty tight (the upside is that it is spill-proof) so I wouldn't recommend the unit for feeble people.

The other part of the unit, housing the motor and fan, comes off easily too. I do wish it had a latch, because you need to be careful not to knock it off when removing the water tank. When the water tank is replaced on the base tray, some water from the container fills up the tray, making a gurgling sound. It makes the same tiny gurgling sound periodically during operation too. This water in the tray is taken up gradually by the filter (which sits under the motorized fan), to generate the humidity when the fan is on.

The digital panel is easy to read. I do not however agree with the humidistat's reading. I have another humidistat in the room that I compare the reading to. The humidifier's reading is always lower, usually by 8 to 10 percent. Setting the desired level of humidity is simple although it can be done only in 5 percent increments. The unit shuts of automatically when the desired hunidity level is reached.

The base is easy to lift if the unit needs to be moved. Of course it is much more convenient to do so after removing the heavy water tank. As long as care is taken not to slant the base tray, there is no leakage or spill.

One point to consider if you are paying heating bills in the winter is that, since this IS a cool-mist himidifier, it will make the room cooler. So you may need to turn up the heat in the room a notch.

Overall, I am very satisfied with the unit's performance and recommend it to any able-bodied adult considering a cool-mist humidifier. To sum up, here are the PROS and CONS:

CONS:
1. Water tank is too large to fit under kitchen faucet
2. Cap on fill hole is tight. Some strength required to turn it
3. Humidistat not accurate
4. Motor unit is not securely latched to base tray to prevent accidentally knocking it off when removing water tank.

PROS:
1. Very good performance
2. Low operating sound on quiet setting
3. No leakage or spilling when handled correctly
4. Portable
5. Dishwasher safe; Easy to clean
6. Desired humidity level can be set manually
7. Automatic shut-off when desired humidity reached

PRO/CON depending on whether you live in hot or cold climate: Makes the room cooler.

3.0 out of 5 stars This model not worth the extra cost., December 9, 2002

Amazon Verified Purchase(What's this?)
This review is from: Hamilton Beach 05521 TrueAir 3.5 Gal. Cool Mist Humidifier
Water Tank:
A large tank should mean less fillups, however, I found myself filling up nearly every night, and I only used the humidifier at "quiet" when I went to bed. It's somewhat simple to fill up, but since you have to flip the tank upside down to fill it, it's cumbersome to fill in a bathtub, which is the only place other than the kitchen sink that the tank will fit for. Since I use this product in my bedroom, I use the tub.

Noise Level:
I thought that the quietest setting was quite tolerable while I slept and I probably could sleep through the mid-level. However, I purchased an identical model for my mother, and she said it kept her awake all night. So, your mileage may vary, but keep in mind that if you are a very light sleeper and bothered by slight noises, there probably is NO humidifier that will be quiet enough for you.

Operation:
The LCD display is large and easy to read. The 2 buttons to increase/decrease the desired humidity and the control knob for OFF/Quiet/Medium/High fan level is very easy to operate.

Effectiveness:
All in all, yes, the humidifier is doing what I hoped it would do. I wake up with less throat irritation and without stuffed up sinuses. However, I purchased this unit thinking that the digital humidity level operation would work precisely. First, the humidity can only be increased/decreased at 5% increments. Second, I have not been able to reach my desired humidity of 50%, even when I've blasted it at HIGH. The highest I've reached is 45% and it's in my bedroom. Unless you live in a mansion, this humidifier SHOULD be able to control the humidity in a bedroom with ease. Not so I found out. Furthermore, when the humidifier is off, the LCD still displays the humidity, but will always drop 3-5% when you turn it back on. What's the purpose of having a humidistat when it doesn't appear to be accurate?

Summary:
All in all, it does the job. But the LCD display and operation is not worth the extra cost, above the cheaper models. I've already shipped this unit back to Amazon.com and purchased a less expensive Holmes model from Target, which you can also purchase through Amazon.com. We'll see how that one fares.
