Is it big enough for 500 sq feet room? Is it really quiet? Does it leave "white dust" around?

It will raise humidity from 25 to 38 in about 10hours in my room that's about 330 sq ft.It's not noisy.I don't have any white dust.

We use the Ultrasonic in a large master bedroom and it is very quite. I do not notice any "white dust" but we live in Southwest Colorado on the Mesa and we have plenty of dust that gathers in the house. However I don't think any of it is due to the Ultrasonic. Worth the money.

The answer is yes, to your question. You may have to raise the level guage of mist. It's very quiet, however, I find you must fill it every other day or so, depending on need. No white dust.

Yes, it works for that size room and is so quiet that I am unaware of it. I keep it in my living room and have another humidifier in my bedroom. White dust has never been a problem, but it needs to be cleaned regularly with cotton swabs to avoid build up of particles in the water that build up an orangey residue.

Hard to say about the size...500? There is a gauge that lets you adjust the amount of mist, you could crank it to high & move it about the room for the 1st couple days. Once the room is humidified a bit it might be big enough (unless you have radiators for heat then i would think 2 machines would be the least you'd want). I've noticed no white dust and have used this every winter for several years.

Probably won't work well for a room that size. No white dust when using the filter and the little ball thing that you can buy that floats in the water.

We're using the unit in a room that's about 420 SF, but it also has a 10 ft ceiling. I fill the unit up twice a day, about a gallon each time. We've had no problems with dry air symptoms although the humidity ranges from 32-42%. The unit is very quiet, particularly compared to our previous humidifier, and we've seen no white dust. We do use the recommended demineralization cartridge (Kaz DC-51) and the antimicrobial cleaning cartridge (Protec PC-1) to help with keeping the unit clean and because of our hard water.

It is pretty darn quiet, I've never measured, but it isn't noticeable if it is running or not most of the time. I've got one in my shop and I hear a window unit from 2 rooms (masonary walls) over it.

I have a small shop and the dust collector is very much in the open. I is not as loud as I expected. Not quiet, but significantly less noise than my shop vac, table saw, etc.

We have not had trouble with noise. I am particular about this so I can tell you it is quiet! Our finished basement is approximately 1000 square feet. We can watch Tv, play games without really noticing the machine. Ours runs continuously. I do have to empty it more often than our last machine but maybe this one is just better at removing moisture? Our basement stays at a comfortable humidity level. (<50%)

We use it in our bedroom and it works well. It's about a 12x15 bedroom. It also has white noise, in a good way, which we like as it's a low pitch.

The unit isn't super loud or super quiet. But you do hear when it is on. However I have slept with the unit just 2 feet away or less with no problem. The noise level shouldn't be a major concern. If it is than this type of air cleaner is not what you should be looking for to clean your air.

Mine is a large room (combined kitchen, living area). This is a good air cleaner for me.

I actually have 2 - one in my office and one in my bedroom. The one in my office I keep on low because it is a little loud and blows quite a bit of air. The one in the bedroom I keep on 24/7 on high. The noise actually acts like white noise to help you sleep and block out any outdoor noises. I don't move it around much. I do move it if I have been doing something in a room that either has fumes or dust. I also have taken out the foam around the inside and have shaken it out. It really collects a lot of dust. I do plan on buying another for the other side of the house to try to get the whole house filtered. I really do recommend this product; it's amazing how it gets rid of pet smells, cooking odors and I can tell the air is much cleaner. Now when I start opening the windows this year, I will only run it at night, since it would be the same as running the heat while having your door wide open.

Yes. It is very quiet. I have it in my Family Room. I would recommend this product.

I would say it was pretty quiet. I mean, you can hear the fan but it is not annoying. In fact, I think it would be rather soothing in a bedroom - kind of like white noise.

You probably should contact the manufacturer to get their answer. The unit is rated for a "large room" and I suspect that 500 sq ft would fall into that category.

Yes, noise is like white noise...very quiet. I believe the value of running the machine is increased by 1) keeping the filter clean and 2) isolating the room by keeping that door closed all the time.

Yes. It's the perfect amount of white noise in my opinion. We've only had it for a few months but it's been an excellent fan.

It is very quiet on low. I have it running all the time and it sits on the other side of my small den, and I can't even hear it running. On medium, and high, yes it gets fairly loud, but I rarely have to put it on high. It is a great air mover, and will blow everything off your desk if on high. You can't go wrong with this fan. In fact, I am about to buy another for my bedroom.

Hi Patricia,We use it in our 200 sqft living room and it works really well. The ocilation feature allows you to get more area heated than a normal space heater. However, it does make a fan-like noise when it's running. It's not obnoxiously loud, just a low hum that really ends up being white-noise, and not something we find annoying. Hope that helps a bit!
