Pros: Easy to clean; come in black; clean the air in absolute silence
Cons: The silence does not last forever, and it begins to emit a high-pitched whine.

I owned two of these units for about a year (there was a buy-one-get-one-half-off sale), and my wife and I noticed the difference in air quality immediately after plugging them in. Maintenance was simple -- just wipe the blades and turn the thing upside down to clean the electrified wires.

After a couple months of use, we noticed they were emitting a high-pitched whine; almost like a mosquito. What was happening was the electrified wires were collecting dust near its base, and was discharging electricity. I tried using an air duster and even a small paintbrush between the plastic grille (unplugged, of course), but couldn't get rid of what whine. Since the units were on warranty, I sent them in for replacements. The replacements arrived hassle-free, but there was a notice stating that these units could only be replaced once.

After another couple months of clean air, the whine came back. We tried to muscle through the noise, but, like any constant high-pitched sound when you're trying to relax, it drove us nuts, and have been placed in retirement since.
