Can this keep my room dust-free and NOT be heard from over 5-10 feet away? thanks

No, it will not keep your room dust free but it will help and no to the second part of your question. This air filter is good, not great, and it is noisy. We find that it is not possible to listen to TV without turning it off. After having used this type of filter for some time I would not rate it as high as it was rated when we bought it.

It won't keep a room dust free, and it can be heard but I don't know how far away you have to be to not hear it.

It does have an operating sound at 5 feet. Not loud sound but a sound. I became used to it in a couple of nights.

Low settings will work for you. This product is of consequence as it relates to indoor air quality. I have 8 units and love the performance.

Great. My bedroom somehow was the dustiest in the house and now with the machine, it has reduced it by half. Good luck.

Yes, if you place it under your pillow the sound is very localized. They won't hear it.

It's not silent, but the net benefit of a room that I can now inhabit is worth putting up with a little noise. I use this in a room that is my designated home office and I spend a good four hours a day on the phone with this fan going in the background. It doesn't impede my ability to conduct business by telephone.

I always use hearing protection when I use the dust collector. I don't consider the noise from it excessive though. It is not as loud as using a table saw. The noise is more of a low tone noise versus a high frequency noise.

You probably will, but not so load it would keep someone up. Some people like a little background noise. I used my smart phone and a noise app and got the following at 11 feet from the fan. Room noise, no fan was 28 decibels (dB), low - 32, med - 33, high - 34. Seemed like more of a drop than that just by ear.

I don't know of anything that would make the unit quieter - for the bedroom. For myself, I find the noise helps me to get to sleep and stay asleep so I have no problem with that. Does a fantastic job of keeping the bedroom very comfortable for sleeping.

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.

not really anything to keep clean. I use it all the time and have not noticed any dust. the area is not that wide. I bought two for me. one on bedside and one on my desk at work. I gave my mom one, she loves it. even bought the one that plugs into my computer. lol

It reduces the noise somewhat. I only covered a door but I figure it you use it over a larger area you will have silence

I suppose it depends on how sensitive your hearing is, and how well you can tolerate quiet background noise. I found it quiet enough for it's location, ie, attic vent.

Say a blow dyer on low. You can notice it but it is not like a bathroom fan it is whisper compared to that. If your in the same space as it it is like the blow dyer on low. Put a wall between yea and you don't hear it. makes it great for attic and crawl space.

Its really not that loud. It makes some noise yes but i doubt they would hear it in the other room. You could also try turning the force feedback down to reduce the noise.

It depends on where it will be vs. where you would be, distance-wise. At my desk, it provides good white noise. At my house, it probably wouldn't be strong enough.

I assume you mean a through wall or window unit. Yes it should absorb sound however you have louver where the air blows into the room which will allow the units noise to transfer into the room. You aren't going to make the unit whisper quiet but it might bring some of the noise floor down. Certainly cheap enough to give it a shot.

No, it isn't that loud, however if you want to set it off in your home or in an indoor environment be careful, keep it at least 3 feet away from you and you should be fine. I have had one blow up right atmy feet about two feet away from me while crouching down during an airsoft match, I only got startled, my ears were not damaged. But just to be safe keep it at a distance.

Since you can not be in the same room or rooms it is hard to say. I had it ine closed off room with another door to the adjoining room closed & could not hear it loudly. Please keep in mind it is a heavy duty industrial ozone generator. You can not stay in the same space with it anyway.
