Hunter 31915 PaperWick Replacement Filter for 32350, 32500, 32501, 32505, 32507 & 34500 Review

Average Reviews:

(More customer reviews)I ordered what were supposedly 4 of the Hunter filters part #31915. When they arrived they were an inch short of the correct size. I could find nothing on the box or filters to indicate that they were genuine Hunter filters. I notified the company who offered to refund me the money if I returned them. I figured it wasn't worth the hassle if they wouldn't just take my word for it and send me the correct filters. I won't be doing business with this company again.

Trion 356686-001 Atomizer Humidifier Review

Average Reviews:

(More customer reviews)This is merely a drugstore style spinning disk humidifier made of metal instead of plastic with a toilet bowl style water filling valve. Loud as hell and back, randomly, due to lack of precision roundness of the very fast (vs. the drugstore version) plastic disk. It's a molded piece that likely is being de-molded too fast so it warps a bit. WRRRZZzzzzzzzzzzZZZaaaahhhhhhHHHHAHHHAZZSZARrrahhhh.... The vibration isolation sucks. It's little rubber grommets that huge metal studs (threaded rods) jut through, topped off by brass nuts. That metal connection links the top plate that holds the motor to the sound board that is the metal bucket. So I removed the brass nuts and the rubber grommets were set free to stop filling my apartment with ugly noise. Now it's white noise. Calm noise. It does NOT put out enough water vapor to do more than a couple of small rooms. Oh, yeah, better than nothing, much better, but not enough to raise my 1200 sq. ft. NYC apartment from 28% humidity much above 35%. But that's enough to help with dry skin and any coughs that linger after I inhale crap all day during my work in an art and design studio. It's a good product. The top has a wire that sort of prevents it from laying flat on the bucket, so I glued it down, but that prevents you from taking it apart to clean the rotor. Doesn't really matter. The float inside that controls the water level in the bucket can be bent by hand to allow a bit more water in so it's deep water the rotor tip is dipping into instead of shallow water which makes it's own type of very odd noise. Stuff of nightmares, that. After all these years, this little trooper is making me feel like it's spring already. The wall humidity control is top notch and uses some sort of wrapped around plastic film to measure humidity. There's enough mechanical "click" to actually measure the current humidity by cranking the knob left and right. The unit puts out vapor instead of actual gas, so hard water issues are mostly solved by the mineral solids being ejected into the air, but unlike sonic humidifiers, it does not put out a fine white dust of hard water evaporate.

Venta 1038036 Venta VS370 Ultrasonic Humidifier Review

Average Reviews:

(More customer reviews)Like the title says right out of the box all it did was blink the display endlessly. The manual makes no mention of this condition specifically, but does advise re-seating the maintenance free box and trying again. No dice. With quality control of this caliber, letting a relatively simply device like this slip out in a completely non functioning condition, I'm not going to give them a second chance or any benefit of the doubt. I'll be interested to see some reviews of this unit from other who might get a functioning unit.
Also the marketing claim that this is the "First ever maintenance free humidifier" is patently false. You need to purchase a "maintenance free box" after every 1 000 hours of operation at around $30.00 a piece. Twenty four by seven operation during the cold months when my forced air furnace is operating means you get about six weeks before shelling out another thirty bucks. Not exactly "maintenance free" in my book or Merriam-Webster s book for that matter - where "maintenance" is defined as "the upkeep of property or equipment".
UPDATE 11/17/2007: Going against my better judgment we did decide to try another unit. Within 20 seconds there was a stream of cool mist flowing into my family room, confirming that my first unit was indeed DOA. The 2 gallon tank lasts around 20 to 24 hours. The top of the unit and the side in which the mist is flowing will always get soaked with water. You will find yourself frequently wiping it down of standing water. No matter how careful I tried it was impossible to remove the tank for filling or replace the tank after filling without getting water everywhere and creating a mess to clean up. I was willing to put up with all of the little annoyances that this humidifier had to offer because it really does make my family room much more comfortable to be in. However, after about five days of using this humidifier I noticed a white film on my television. Then I noticed that the white film was on everything. It took forever to clean up and quite honestly I don't think I'll ever be able to fully remove the dust and film that was deposited everywhere. I should have went with my gut instincts on this one.
Similar to my rant above regard the "maintenance free" box, the manufacturer makes very specific claims: "No germs, no filter, no cleaning, no white dust". I've never owned a humidifier in my life that generated so much white dust. The claims made are so definitively false, and I can't believe anybody at Venta would believe them to be true, that I'm tempted to bring the matter to the attention of Consumer's Union and/or my state attorney general's office.

Hunter® Care-FreeTM Humidifier Plus/NiteGloTM - 2.2 gal Model - 16"x13"x14" Model # 33222 Review

Average Reviews:

(More customer reviews)The Hunter NiteGlo Night Light Humidifier fulfills my needs for an overnight humidifier. Given I do not run my furnace from 10pm until 4am my bedroom does get a little dry and waking up with a dry mouth several times a night can be annoying at best. So I decided to pick up this machine with the hope it would end my suffering. With varying speeds this little unit does what I need it to do. The humidifier itself has a washable filter so you don't need to constantly buy expensive filters. It comes with a nite-light so that you can monitor the water level easier and provides minimal light to see in the dark, but not bright enough to interrupt sleeping.
The motor can be a little loud and it will take some getting used to if you are a lite sleeper. The water container is pretty small and takes about 48 hours on medium speed before refilling. The humidifier works by pushing air through the water soaked filter, so it doesn't actually mist like some humidifiers do. When the water container goes empty the fan does become louder and the water left in the bottom of the unit does gurgle pretty loud. The water as it filters down into the tub does gurgle as well but its not that big of a deal. The unit breaks down into five different parts, the water container, tub, filter holder, and fan unit, making it easy to clean. The parts(not including the fan unit) made it through my dishwasher fine and the filters are easily washable in hot sink soapy water. All-in-all a good machine.

AOS 2055A Automatic Air Washer Review

Average Reviews:

(More customer reviews)For details, including photos of the internal workings of this evaporative humidifier, look for the 2055 AirOSwiss reviews done elsewhere on Amazon which has plenty of images of the inner workings. To summarize, it's an evaporative humidifier which works by drawing air in through the top via a fan then over a disk pack of about 10 slowly rotating plastic disks which dip into a pool of water, then the air exits the side carrying the humidified air.
Pros: No heated element to worry about overheating when it runs dry, no ultrasonic misting to leave water droplets on carpet/furniture, easy to clean, no filters to be replaced, and it traps air particles on the discs with the water so it does 'wash' the air.
Cons: Evaporative which means it cools (fine for the desert country, not so good in winter in the Midwest), no heating, and the fill valve on the water tank is the stupidest location you can imagine, so that at best you can fill it only 3/4 full.
The other con: They SAY on their website they have a 10 year warranty, yet when I got this thing from Bed Bath and Beyond the plastic shaft inside had corroded from time and was crumbling. It was a major effort to get these guys to agree to replace it. It is NOT SAID on their warranty, but apparently the 10 year warranty does not apply to the rotating disc set (surprise!). I told them they had better put that in writing if they don't want to tick off a lot more customers other than me. They eventually replaced it. Also note, the 10 year warranty does NOT apply to the water tank and its part . . .that's only 3 months.
For $260 bucks or more, the above limitations cut it to a 3 star, even though it's a reliable humidifier that cranks out the humidity from the unit with no filters and very little maintenance. As a personal aside, I can't stand the reviews which deride humidifiers because their hygrometers show no change. Humidifiers can only be evaluated by how quickly they put water into the air . . . the ultimate humidity change is depending on the room's air flow, items of absorbency, and atmospheric conditions- none of which are in the control of a humidifier!

AOS 2055A Automatic Air WasherHumidification SystemThis 2 in 1 Humidifier & Purifier washes and humidifies a room's air without evaporator mats. Special humidifier discs turn through the water removing impurities from the air naturally, which gives great relief to allergy sufferers. Therefore it is called an Air Washer. The discs, which never need replacing, have a great adhesion for water to guarantee high humidity output. The Air Washer is equipped with the Ionic Silver Stick (ISS) anti-microbial protection system that helps prevent microbial growth in the water base. Microbial protection is particularly needed when the humidifier is not used for some time with water remaining in the base. The AOS 2055A automatically switches off when the water base is empty.Comfort and ClimateThe pre-ionizer charges particles as they enter the air washer. These small charged particles, down to 1.5 microns, form larger dust clusters that cling to the humidifier discs and are removed as the discs turn through the water.

William Ultrasonic Humidifier in Black Review

Average Reviews:

(More customer reviews)I recently moved to Aurora, Colorado (just outside Denver) and at 5,400 feet the humidity is extremely low. I noticed my skin began to itch, which it had not done before. My doctor advised moisturizing creams, which helped a bit, and an air humidifier. After a lot of investigating I narrowed my search to the Air-O-Swiss and the Williams. In fact, both units seemed remarkably similar with both using a "patented" ionic silver cube and a filter cartridge which seem visually identical. Both units provide warm and cool mist. Possibly the technology is licensed from Air-O-Swiss? The deciding factors for me were:
(a) the Air-O-Swiss listed a capacity of 650 sq. ft. and the Stadler 1,000 sq. ft. I have a very small house - 850 sq. ft. - which effectively makes the Stadler a whole house humidifier for me.
b) almost every review of the Air-O-Swiss commented on the inaccuracy of it's humidity meter and the only review I could find of the Stadler said it's meter was accurate.
THE GOOD: Assembly is a snap. The meter is close to accurate. The water tank is extremely easy to remove and fill. It is dark plastic, but the water level can be seen quite clearly. The tank capacity is sufficient for 9 hours of continual use. The machine is so silent that I have to listen closely at night to hear anything at all. Just a soft "ssshhh." The Control Panel is easy to see and use with many options and has a light to indicate no-water.
My skin itching stopped.
THE NOT SO GOOD: It is expensive and every source I could find had the same price. The filter cartridge needs to be replaced three or four times a year, depending on the hardness of your water, or when white dust accumulates on the unit or on a small mirror held to the fog. The ionic cube must also be replaced once a year. A testing strip is included and if your water has a hardness greater than 21 degrees dH, an ionic humidifier is not recommended. They suggest then using an impeller humidifier. The Desired Humidity cannot be set lower than 40%, but I found that setting it at 60% results in an actual humidity level of about 37% which is what I want anyway.
THE BAD: I couldn't find any.
SOME NOTES ON OPERATION: The instructions say not to place the Stadler Williams directly on the floor or next to heating. I went to Ace Hardware and found a small, plastic step stool for $12 that is 5" high. This keeps the unit off the rug and makes it easier to access when changing settings. If you have an chest of drawers in the room with space on top it should work equally well. A review of the Swiss-O-Air reported good results from soaking the ionic cube in water for 24 hours before initial use to increase effectiveness. I don't know if this is beneficial, but I did it and had no bad result.
I set my unit to Auto/Sleep
IMPORTANT: Several reviews of the Air-O-Swiss said that they used de-ionized water. The Stadler unit specifically recommends against this. It is designed to use with untreated water or with a drinking water filter system such as Brita. Using any additives are specifically warned against.

Air-O-Swiss 32838 Ultrasonic Humidifier Review

Average Reviews:

(More customer reviews)WHEN it works it is OK. It has all of the defects described by the other reviewers. But they make up for the defects with rotten customer service. I bought this unit on January 31 07. Used it until the end of March, at which time I cleaned it and replaced all of the consumables per the instructions. I put it back in service two weeks ago. Six days ago it stopped working. I called their customer service. They use an out-sourced customer service group that will NOT talk to you, but rather, insists on taking your number and calling you back in the evening. Of course, they called back when I was out and left a message that they would call the following evening. They did not. I called back the next day and went through the same thing. That evening, since thay had not called by 8:30, I called them. This time, they insisted that I go through some trouble-shooting (all of which I had done previously). They then told me to leave it unplugged for a 1/2 hour (by which time they would be gone) and then "reset" the unit by pressing a button combination. I did this. The next day I called them again and got the same "wait until tonight" pitch. I insisted on an RMA number, which I received. HOWEVER, before they will tell you where to ship the unit, you need to FAX them a proof-of-purchase (their email address bounces back). The you have to wait for them to call. It is now 6:30PM on a Friday night and no call. So I called them and got their voice mail, where I was instructed to leave a message. So It will not get shipped to them this week. Next week I am traveling, so it won't get shipped until the following week, which means that they will not get it until after Christmas, which means it will be mid-January before I get a repaired unit. These people are total idiots. For a $200 humidifier, I would expect some sort of real customer assistance. Be warned before you buy.
UPDATE: Well, a month after I sent the defective unit in, I received a TOTALLY DIFFERENT AND MUCH CHEAPER UNIT in return. I am now on my THIRD phone call with these idiots and have yet to talk to someone who can resolve this problem. The right person is "not in the office" and will "call me back." HAH!! They NEVER call back. I wish I had never heard of these people.

This efficient Air-O-Swiss Ultrasonichumidifiier uses several cutting edge technologies to achieve an optimum quality of environmental control. High-frequency vibrations generate a micro-fine mist, while an Intelligent Temperature Compensation system (ICS) measures humidity relative to the room temperature and automatically adjusts the output to achieve an optimum balance dynamically as conditions change. The water is kept clean with three separate processes that make up the Microbial Protection System: ultrasonic technology, pre-heating, and Ionic Silver Stick. The latter makes use of the proven anti-microbial qualities of Silver, which has proven effective against more than 650 types of bacteria without any chemical additives. When operated with the pre-heating function, the water is heated to 176°F before it enters the nebulizer chamber. The mist exits the appliance at a comfortable temperature of 104°F. This neutralizes the cooling effect of mist to keep the room temperature from falling, and also keeps the water cleaner. A replaceable demineralization cartridge ensures a hygienic, pure water mist, without lime scale or mineral residues. Exchangeable demineralization cartridge / Quiet operation /Easy to clean and handleSuitable for rooms up to 860 sq. ft.

Venta Sonic VS205 Cool and Warm Mist Ultrasonic Room Humidifier Review

Average Reviews:

(More customer reviews)WOW! Finally one that WORKS and doesn't wake the neighbors!
We have been through just about every type/brand of humidifier in our quest for the perfect one over the last 15 years. So when I pressed the "on" switch on our new "Venta Sonic VS205" I knew our quest was finally over. Out came an unbelievable "fog cloud" of humidity that gently wafted over the room. Later as the humidity level rose - monitored by the nifty LCD readout on the front - the unit suspended "cloud formation" and waited patiently until the room percentage had dropped below the set level and then resumed.
Pros::
1) Absolutley soundless!!! Many of the other brands worked fine but were so noisy we couldn't sleep.
2) Runs at least 24 hours on a fill (depending on what level you set it on - ours is 45% - 50%)
3) Instant gratification - monitors the humidity level in your room - not many actually do this - you just have to guess and never really know - so this is big.
Cons:
1) The only one - it's a bit tricky to fill. Have to turn the tank upside down and unscrew the filter. As an Industrial Designer I could come up with at least 3 better ways to do this - one being simply have another fill cap on the top. But this is really not a problem since the unit has so many other admirable features (AND - you only have to do this once a day!!)

Vornado Whole-Room Evaporative Humidifier, HU1-0021-28 Review

Average Reviews:

(More customer reviews)Vornado HU1-0021-28 Whole-Room Evaporative Humidifier
After owning this for some 2+ years, I have updated this review and raised the rating. The following text is updated:
We have owned a number of humidifiers in the past. The last one we owned (& liked) was the now discontinued Vornado model (the ugly gray box w/ 2 water tanks and a fan that sat in the lid). This new version, solves some of the problems of the old design and creates new problems of its own. As another reviewer has noted, the beauty of the old system was its simplicity (read: fewer parts to clean). That simplicity, is somewhat gone.
The biggest improvement is the noise level. The old design made a loud gargling sound periodically as the air bubbled into the tanks. Further, the lid with the fan, sometimes did not sit right and made a buzzing vibration sound.
The other major improvement, that it has taken me sometime to appreciate, is that there is less water sitting around in a basin that can collect junk and grow nasty stuff. This ended up needing less cleaning than the orignal model. On the other hand, the black color also makes it harder to appreciate mold inside the unit.
The new tank now has a filling cap that locks into the tank. There is a separate fancier spring loaded drain for water to move into the basin. I had some concern abou the top of the tank not being flat and making the filling more difficult. However, it seems sturdy enough as long as you are careful and don't use as much high pressure to fill it. There is no longer an option for two tanks, so more refill runs.
As for the rest of the design, there is now a physical separation between the evaporation chamber, and where the water tank is placed. This is mostly nice, since you don't have to worry about bugs and other junk falling into the evaporation chamber. You have to be a little more vigilant about mold buildup inside the chamber since it is closed off and not visible on every refill.
On the plus side, the fan is more securely attached to the rest of the humidifier, thus reducing noise.
As far as humidification, it still works great. The fan is quieter and just as efficient (if not more). The fancy electronic humidification settings seem to work well and allow for less over-humidification (fewer refills). So in summary:
- quiet
- efficient
- not as simple a design as the older model
- more parts but seems to need less cleaning.

Germ Guardian H4500 120 Hour Ultrasonic Humidifier Review

Average Reviews:

(More customer reviews)When I first moved to the high mountains (8400') of Colorado, I used a wick-type humidifier constantly. I also had a nasty little cough that stayed with me for 18 months. Finally, I took my doctor's advice and junked the humidifier. End of cough, due to things growing in the unit. I have been shopping for humidifiers again for a while, and found them all to be lacking severely. Either they were the same type of filter construction that had caused my illness, or they were cheaply made, or low-capacity. This unit may have a tippy storage tank when turned upside-down to fill, but it is well made. The screw-on cap for the reservoir is sturdy and has a rubber gasket. There are carrying handles on the top and bottom of the water container to make it easy to manage, and it puts out a LOT of humidity. At 2/3 setting, it ran the humidity in my bedroom from 22 to 35% the first night, all while being completely silent. The (silent) piezo-electric ultrasonic element is the same as is used in the tweeters of my big PA speakers, and these are practically indestructible if kept clean. The huge water reservoir does mean that it is big, and the styling is retro, which is OK, I guess. More expensive units from the same manufacturer have useless and noisy digital features with the same overall construction. Overall, a solid five.

SPT SU-4010 Ultrasonic Dual-Mist Warm/Cool Humidifier with Ion Exchange Filter Review

Average Reviews:

(More customer reviews)Pros:
1. It actually turns on. I got this unit after my Crane Adorable Humidifier (Penguin shape) refused to turn on.
2. It just works. I have a 10x13 room and this humidifier took my room's humidity from 21% to 42% in about 3 hours.
3. I really like the form factor. The unit is only 5.31 inches deep so it can easily fit on top of a short bookcase that also has a small depth. Few other humidifiers would fit where I have this humidifier right now.
4. It is fairly easy to fill. The top of the tank is flat so that when you turn the tank upsidedown to fill it, it can lie flat.
5. I'm pretty happy with the mist quality. Even on the highest setting, you're not going to see fat droplet sizes coming out. You are not going to end up with a puddle on the floor as long as you put it on a surface at least 2 feet above the floor.
Cons:
1. Some reviewers have complained about water leaking out of the tank. I noticed that on my unit, the washer (or o-ring) for the tank cap is a little bit too big. If you turn the cap shut too tightly, the o-ring will roll on itself, and the next time you unscrew the cap and screw it back on, the washer may not provide a good seal because it is out of place. Even the manual tells you to make sure the washer is in place when screwing on the cap. As long as the washer is in place, it won't leak. This is just a slight annoyance.
2. If you are blowing warm mist and you want to change it back to cool mist, it'll take awhile for it to become cold again because the unit does not actively cool the water. You'll have to either pour out the existing warm water in the base or wait until all the warm water in the base gets sent out. I am not a big fan of warm mist so it's a non-issue.
3. The unit is fairly quiet and I am pretty sure most people can sleep with the unit on without a problem. However, I am an ultra-sensitive sleeper and anything louder than completely silent is too much for me. If it was the just the humming noise, I think I would be able to take it, but what bothers me the most is the inevitable random water sounds caused by the ultrasonic plate generating large droplets of water and those droplets of water coming back down. Almost every humidifier will do that. The water noise is fairly low, it is just the randomness of the noise that annoys me when I try to sleep. When I am awake and my computer is on, I barely notice the humidifier because my computer is many times noisier than the humidifier and my computer is already pretty quiet.
Tradeoffs:
1. Yes, the tank is only 4 liters, but do you want a humidifier that fits on a bookcase or not?
2. Sure, the tank only last 12 hours on the maximum setting, but isn't that the point of a humidifier? If you desperately want humidity, wouldn't you want the humidifier to empty the tank as quickly as possible?
Other thoughts:
It is nice that this unit comes with a water filter, but of course the manual will recommend that you fill it with distilled water rather than tap water. Considering that I'll be breathing the water I put into the humidifier, I've been filling my tank with water that I've passed through a Brita filter in a water pitcher. However, doing that is somewhat a pain because it takes multiple pitchers to fill up the tank. I am thinking about getting a faucet filter so that I can fill the tank quickly.
UPDATE: My 10x13 room just hit 50% relative humidity and I'm loving it. My windows are starting to fog up, maybe I should turn it off.

Breathe easier and sleep more comfortably with this virtually silent dual-mist humidifier. It helps provide year-round relief from the drying effects of air conditioners and heaters, including dry nose, throat, lips, and itchy skin. The ultrasonic humidifier disperses warm or cool mist, while its 360-degree adjustable split nozzles offer bi-directional mist for wider coverage. In addition, the unit's ION exchange filter demineralizes and treats water to remove scale-forming calcium and magnesium from hard water. This prolongs the life of the ultrasonic generator and prevents white dust particles from depositing into the air. The humidifier's 90-watt warm-mist setting delivers about 400 ml of humidity operating up to 10 hours on high, while its 43-watt cool-mist setting delivers about 330 ml of humidity operating up to 12 hours on high. The unit comes equipped with a 4-liter water tank, overheat protection, a 5-8/9-foot power cord, a cleaning brush, and a sleek design with easy-to-use control knobs and a carrying handle for convenient portability. Designed for rooms up to 500 square feet, the ETL-approved humidifier measures 5-2/7 by 13-1/5 by 12-2/5 inches and carries a one-year limited warranty.
