Question: The transformer makes clicking noises like an old electric blanket--is this normal?
Document: Otherwise, it makes no noise at all. The clicking subsided after a few hours. That's about all the device "does".Whether the device works is subjective, which is why I insist you have to have a little faith in the manufacturer that it's working. In essence, the device attracts particles to the collector. Any particles in the air that are too large to be statically attracted to the device will get heavier and drop out of the air.
I have never ever disliked a product so much as to go to the extent of making my voice heard. The only dust this thing collected was the dust that would have been collected on it had it not been plugged in at all! This thing looks very cheap and is definately not worth anywhere close to the price it is selling at. It makes all sorts of crackaling noises only to make you think its working, when in reality it is not.
The instructions say that the purifier will emit mild electric shocks that won't be a problem. Actually I found them intolerable. If you have a place to put it where neither you nor your children, grandchildren or pets will have to get near it, then fine. I don't have such a place, and I had to pack it up (a nuisance job, trying to get all the parts back into the box) and return it.
Other than generate a slight static electric shock if you get too close (which IS its own form of entertainment when my little boys get nearby) as well as provide a minor night light for navigating our dining room in the dark, this device seemingly does nothing at all that I have been able to verify. If it really DOES clean the air, I have not been able to tell one bit.
I would like to have it working in my livingroom but it turned off in 5 minutes. I will ask for another one.
It is very amazing.It is useful.I like it.good good good good good!useful useful useful useful useful useful useful!
I put the air purifier in my living room first, and after about two weeks the collecting unit was all covered in very thin fuzz. It was very easy to clean off. Now it is in my kids bedroom, they really appreciate the light, and I like that their air might be cleaner.
Again, this is highly subjective, but I do believe the device is working as it should. The air just "feels" cleaner.If you're the type of person who needs to "see" the dirt in a filter to believe that an air purifier is working, you won't like this device. If you have a little faith in the device, and don't mind dusting one or more rooms a little more than usual, then I would recommend this device.
This is the &#34;BEST&#34; air purifier I have ever owned. The air particles become fixed to the outer cylinder and all you have to do is wash it with soap and water and it looks like it is brand new again. My Husband used to say that our living room smelled like an ashtray in the morning but ever since we started using this.....No more bad smell.
The guard consists of two plastic rings and countless flat spokes that you must assemble like a little "erector set". It took about 10 minutes to put this piece together patiently. You don't need to use it, but I recommend it.There are four lights in the device that you can either turn on or turn off. The lights are blue. It's a pleasant shade of blue and not very bright.
Answer: No. I've owned two of these and they do not make noises unless you touch them while on.
