Donna Testa: Do not purchase. This is worthless. After a few weeks of these air purifiers doing nothing, I decided to take one apart. IT IS EMPTY INSIDE. Nothing in there to do any purification of the air. Unbelievable. All it appears to be is a rectangular empty box. How's that for getting nothing for your money?

THIS is a scam item. DO not be fooled, like I was. Unfortunately, I missed the return window but I am letting you all know not to bother spending money on this.
Amazon needs to investigate this and stop allowing this product to be sold on their site.

SneakyNinchilla: I saw a few reviews from people who seemed confused, who insisted these do nothing. I thought I'd buy them and see what was up.

Firstly, I'm in the medical field. I knew of ion generation as a antiseptic technique. It has been used to take out tuberculosis, salmonella, and others.

Here are the highlights in FAQ:

1. Do they produce ozone?
a. Technically, yes. When you create negative ions, you also create a electrostatic field. When this field discharges, it creates ozone. Have you ever lifted a wool blanket and watched the static shocks? Do you remember the smell? That is ozone. These produce less ozone than your wool blanket.

2. Do they disinfect?
a. A little. Negative ions are wrestlers. They can pin down particles and vapors that might carry airborne disease. They don't KILL the germs, at least, not as well as ozone. But the certainly can keep them out of the air.

3. Do they work? How do you know?
a. I know they are producing ions because they have an electrical potential across the carbon fiber brushes. My voltmeter read 8.5v on DC, and 16 on AC. Of the four brushes, two are anodes and two are cathodes. You can short out the device...

I.R.Stamper: Ok, I read all the reviews and decided to give these a try. I got the 3 pack. I have 3 dogs, and we hike daily, often getting wet from sudden showers or because I let them go for a dunk in streams, deep puddles, lakes, etc. And then my house smells of wet dog for days! One of my dogs also has skin problems, not bad but enough that she often has a musky odor to her, which permeates the entire house. So when they arrived, I placed one in the livingroom, one in my bedroom, and one in the family room, which is always the worst smelling room because all of their beds are in that room. After 3 days, to my dismay, every morning I'd wake up, walk into the family room and the funky smell would hit me smack in the nose. And I thought, these things don't work worth a darn! I unplugged the one in my bedroom, to pack up to return... and thought "wait a minute... that family room is big, 13X11 feet big! So, I placed the one I had just removed on the opposite side of the family room from the one that was already working in there. BINGO! Within hours the family room smelled NORMAL! WITHOUT washing dog beds for the umpteenth time, without shampooing carpets again, and without bathing the dogs!...

Janetsart: The pice is great, my allergies are much better. The only complaint I have is how hard it is to plug something else in at the same time in the same outlet.
