Whining sound I recently purchased this air purifier. When I put it on the high setting, there is an annoying whining sound. It only occurs on the high setting. I have noticed that if I lift it or tilt it slightly, it stops whining. It makes me think that maybe something isn't quite level inside. Then again, if that was the case, why doesn't it do it on the low and medium settings? I think I may have gotten a defective unit. Don't really want to go through the hassle of returning it, but I may have to since the loud sound is annoying and even bothers my dog. Whining sound I recently purchased this air purifier.

So after four months of owning this product, the whine got worse and yesterday the unit died. What a piece of junk.

I have the same problem, and it usually does this while I have the unit running for more then a day straight. I think it is some kind of vibration from the motor and the plastic. I'm not too happy with this filter after having it for three months. My allergies seem worse then ever, and I've replaced the prefilter and have vacuumed the HEPA filter.

I purchased 2 of these. After a few months, the first one began to chirp or squeak. A short time thereafter, it stopped working. The second one is still working but sounds terrible. Never again will I purchase this brand of air purifier.

Its not a consideration. It's not as loud as my himidifier, not as loud as the air circulating through my ductwork, not as loud as the AC. I might put it on par with, I dont know what. I actually didn't notice the noise so I can't recall. I guess it can't be that loud.

I'm not familliar with the Winix unit but the Hunter that I have has been running day and night since I got it except when I clean/change filters and as long as the machine is set to medium speed I can barely hear it. It is a little noisy on high speed but that is just the wind noise. On low speed I have looked in the past to see if it is on. Now, that is quiet.

I love my sprite for the way I can maneuver it around my house. As for the noise, I am not the best one to ask as I am sort of deaf. It bothers my dog when I vacuum, but she's spoiled and resents my doing something that doesn't involve her. She is the reason I got the vac in the first place. Sorry I couldn't be of help.

Do you mean volume when you say "v"?If so, yes it makes a sound. Is it annoying? No. I can say as an audio technician, I'm always on the hunt for sounds that don't belong in a setting. I have a very low tolerance for noise and this does not bother me in the least, even in the same room. The air quality it produces is wonderful. I rarely take allergy meds if I'm at home now, whereas it used to be a constant for me.

The settings are more about the heat output and not so much about the amount of air blowing from it. It isn't overly noisy. However, I've had this one for 3 years now and have had to go through the painful process of contacting the manufacturer, jumping through the hoops requesting repair ticket, boxing it up (and it must be in the original packaging or they won't accept it), lugging it to UPS store to ship, and then waiting, waiting, waiting for it to be returned. I've done this twice now. Yes, it has a 5 year warranty, but when it craps out again (as I'm sure it will), it's going to the junk pile.

Our dogs are giant breed and relatively young (ages 4-7), so I'm not comfortable answering about old dogs. The noise is rather like a hissing sound (like an exaggerated form of the sound aerosol hairspray makes) and it releases a calming pheromone. It's not loud (not like an airhorn or anything like that) but for some reason the dogs find it an unpleasant sound and after a bit they stop. As to biting the groomer, I might suggest you talk with a dog trainer for ideas on that. We've had great luck with the Petsmart trainers in our area in helping solve some of our rescue dog issues.

I've never heard a loud whirring with my unit. The only time the disc makes noise is when it is first loading. If it is a home made DVD, the player makes lots of "searching" noises, but when it finally starts to play, it is very quiet. I'd say your friend has a defective unit.

Yeah mine does the same too after using for about 2 weeks. It's really annoying especially now when I returned to work. It's difficult for me to use because the walls not soundproof (it's a room divided in half with rock sheet) in a small medical office. I fold a small piece of paper towel in it because I noticed that milk goes up there. It kinda helps a bit. It would be quiet and then squeek and then quiet and squeek no matter what I do though. Just a matter of how long it would stay quiet. Can't figure out why.

I have not really noticed a noise, but I also use it for the most part in a room that always has an air filter running. I would have to try it out in a "silent" room to be certain. Like the others said, I am sure Amazon would replace it for you!

Check the manual. There is an automatic filter to cancel out those annoying noises...works pretty well for us. Good luck!

Mine did not do that and still has not done that. I have had mine for a few years now and love it. It is very, very quiet. I can actually watch tv while I blow dry my dogs. Is it possible there is a piece of paper in the grid that it is whistling by? If there isn't anything, you may want to send it back and tell them to check the one they send as a replacement to make sure it doesn't do it. My friend has had one for at least 10 years and hers is still very quiet.

There is a significant amount of noise during operation, yes--particularly on the higher settings. This is in fact he reason I purchased this model over silent ones. Not only do I have several pets in my house, but I also need white noise in the background while I am sleeping, and this fit the bill for me. If you are looking for quiet operation, you'll probably want to consider another product.

Ha-Ha! Never thought of that. Mine isn't as loud - perhaps because I used foam on all 4 sides (the peel'n'stick type) on the window itself. Yes, there is noise - the unit is pretty basic (and I knew this) - but the price was good, so I balanced out the noise with $ savings. Also, it seems that the unit is pretty crudely built, so maybe there are noise levels which vary from unit to unit. It runs well, for me. I also live in NYC, so noise isn't an issue, it's a daily lifestyle.

Hello Kitcat, Thank you for contacting Tools for Wellness! The VI-2500 does have a subtle whisping noise and sometimes you'll get what sounds like a crackling noise. Its not particularly loud but is some what noticeable. Most ionizers have the same type of sound. If its loud you may have a defective unit. Let us know if we can help. Thank you!

It's noticeable but not the worst I've heard. Putting it up high (be careful, drippage) might block it. We had music and the noise wasn't a problem. Can definitely talk over it. Please be aware that I personally had TERRIBLE dripping problems with mine but perhaps it was a defective item. Best of luck if you purchase!

The noise I experienced sounded like the unit was under water. It was so annoying I didn't want the thing on. I finally figured out that they build all these units now to not drain water in between the compressor fan and condenser coil in the back of the unit. The compressor fan than using a sling blade to slosh the water up on the condenser coil cooling it. Although this makes it slightly more efficient, I couldn't stand the noise. One carefully placed drilled hole in the back right in front of the condenser coil and the noise is now gone. The unit is finally super quiet again (as far as window air conditioners go.
