Viatek's Ionic Wind Air Purifier Cleaner (with Night Light) is a small simple ionizer. There are several good things about using an inexpenisve plug-in like this, and several downsides to them as well.
I'll start by explaining what a negative ionizer is, an "ionic" machine, and then we'll cover the pros and cons. I started buying negative ionizers and ionizers like this as a young boy because of their reported benefits for asthma.
Viatek cleverly gave this model a name very close to "ionic Breeze Air Purifier" model which was highly popular before it ran into problems when it created ozone. In fact you can think of it as a midget ionic breeze air purifier.
Follow the link below (click on the image) to read the reviews on this model:
It has a two speed little fan that pulls the air in past the electrostatic stainless steel grid. It has a slide out stainless steel grid (plates) that is easy to clean. Just wipe the grid once a week. I'm not sure if it is washable but if you wash it make sure you let it dry first to prevent shocks.
* Reduces Pet Odors, Kitchen Odors, Smoke
* Cleans the air while you sleep
* Slide out stainless steel grid for easy cleaning
* Simply rinse or wipe clean - No filters to replace ever!
* Soft Glow LED Nightlight
For $10 dollars it would take some of the pollution and odor out of your home.
Other than a bathroom I don't think I would both much with this air purifier.
