I use two large humidifers daily. They run non-stop in the winter.  I used to have to clean fungi and mold off my humidifers every few days, but now there is no fungi and mold.  I still clean them but I do it every two weeks.

Unlike nearly all of the humidifiers that I have owned, still going strong, and it's been a couple of years!

I use it in my bedroom and if I keep the door closed, I really notice the humidity when I walk into the room. The design looks goofy for an adult without kids, but this thing really works well and is very quiet. Maintenance is the same as for all humidifiers, kind of a pain but a necessary evil. Dump, rinse, and refill every day and then do the white vinegar disinfect routine every week. There's a little youtube video that shows how to disinfect.

Best humidifier I've used. This things really does work well. It keeps my entire house at whatever setting I establish. Never lags behind. Easy to refill. Be sure and use the bacteriostat in your water.

Long lasting and does a great job.  Already had 2 of these but kept moving them from room to room as needed for continuous use in various parts of the house.  Think you'll like them and get some real relief.  Enjoy.

We liked our first humidifier so much that we've bought an additional one.
Now we have one for each bedroom during our dry winters.
The only thing I don't like about them is they are sometimes difficult to clean.
Otherwise, they are great for refill volume and airflow.
I shopped around online & at stores.
Amazon still has the best price (Dec 2009) even with the Christmas sales.
Cheers!

This has a very generous tank.  It's quite energy efficient.  Due to the fact that distilled water is incredibly expensive to run in a humidifier, it is worth the money, as far as I am concerned, to fill it with water run through my PUR filter on on my faucet, knowing that I may only get 2 or 3 seasons out of a humidifier which I will then replace.  The apartment I live in is very, very dry, and I find a humidifier an absolute necessity in the winter months.  This was a fantastic purchase for the money, even if I was to only get 1 season out of it, although I'm sure I'll get more.

I love this humidifier.  I love that you can control the humidity.  It does not get everything wet that surrounds it.  My only complaint is it is quite large and takes up a lot of room.  But I think it is worth it, because it is the best one I have ever used.  It is very easy to clean.  I love the idea of never having to buy a filter.  I have really liked it.

This is a great humidifier.  I liked it so much that I bought a second for my boys room.  It is whisper quiet. Holds more than enough water to last a long night (plus extra).  Also, the night light turns off.  In the past I have had to use tape to cover unwanted lights on other humidifiers.  Great product.

I use it next to my bed, so I love the silence of this humidifier and the fact you can turn off the display. The humidistat function works very well to run without depleting the water tank nightly (mine lasts ~3 nights). I did have a problem with my first unit after a month with the fan making a loud rattling noise, but the manufacturer worked very quickly with me to replace it and the new unit has worked many months (and now after being stored for 8 months) without issue.

I use this in my humidifiers at home and work. I've used BestAir humidifer stuff for years because their stuff has consistently extended the life of my humidifiers and my humidifier filters.

This is a great humidifier! It's way larger than I expected. I like that it can run for up to 24 hours on one tank of water. My favorite feature though is that the tray can be washed in the dishwasher! This is such a great feature and I highly recommend this humidifier!

This humidifier is the best we have ever purchased ! It's quiet and because of the large capacity, I fill it once in the morning and once at night.

I have tried many humidifiers and would need to purchase one every year because they just did not put out the moisture as they said they would.  This humidifier (we have the elephant and the frog) actually work.  I have had them both for 5 years now without any major issues.  They can get a little leaky so we put them on a storage bin lid and never have any problems.  They are quiet, there are no spongy filters to replace and you can actually see the water vapor come out of them.  We do buy the filter for them and you will need to clean them out because mold can develop just as with any product that holds water. I would recommend these to anyone who needs a functional humidifier that they want to keep for several years.

I use this in my pedestal-style humidifier which cranks through a lot of water in a day.  So far, it appears to be keeping my filters lasting longer as I have not had to change one yet nor do I have any odor issues with the water.  I add some to every bucket of water I pour into this humidifier.  You only need a partial cap full for a whole bucket of water so it lasts a very long time.

This humidifier is huge. It can humidify up to 2,500 sq ft. It has caster wheels on it so you can roll it from room to room. It has two tanks which you can fill at the kitchen sink one at a time or you can what till they both run out and fill them. It will shut off if it runs out of water as well.
It makes more noise than you would expect and every so often it will make a what I call a gurgle blurst (patent pending), but youll soon get used to the noise. It does put out a lot of moisture.
Despite the noise, it is very easy to use and you during winter months you may want to run it constantly. Luckily, that is what its built for.
I tested the Honeywell Console Humidifier for free, but all opinions are my own.

This humidifier works for two medium-large rooms. On low, it keeps going for 12 hours. On high, it goes for 6 hours. Definitely helps my sinuses, which get very dry and easily infected in the winter. Also helps my plants stay healthy.

Unfortunately, one of the two I ordered became annoyingly loud after one year.
