I bought a Paralda in Nov 09 and tested it (during the 30 day return period) with a Laser Particle Counter. (for the tech savvy: a swiss "Particle Scan Pro", detection range 0.3 to 30 micron)
these are the results: - outdoors: 230,000 particles per litre of air (p/l) (and that was a "clear air" day, a bad day sees a million and more) - indoors: approx. 160,000 p/l - in a room with an Alen Paralda, on speed 3 for 1 hour before the test: 10,000 to 11,000 p/l - directly at the air outlet of the Alen Paralda: 800-1,400 p/l
To give these values some meaning: more than 105,000 p/l are considered a health risk by the W.H.O., anything below 60,000 p/l is considered good air quality, high up in the Swiss Alps you will find 2,000 p/l.
The Paralda did remove up to 99,5% of the particles, and reduced the room particle load by 93% within only 1 hour.
So - it does exactly what it says on the tin, I kept it and I am buying more Paraldas and an A375UV for the rest of the house.

May I submit that having both a Sharp Plasmacluster and the new Alen Paralda, the Paralda wins hands down after using it for the last ten months. For my use it was like night and day and within 3-5 days was noticeable to my wife who suffers badly from pollution, minor allergies and any dampness.
Even for myself, I find having the Paralda in our master bedroom has taken away the dry throat I used to have in the mornings. Not to mention my children have found the same.
I am definitely going to purchase a few more for the bedrooms and an A375UV for my large living room.
I personally cannot stress enough how important it is for us to breath the cleanest air possible. In Hong Kong, we are all challenged by both pollution and hiding in our homes which only traps bad air and recirculates it!
Again, even those who do not suffer in an obvious way I believe are just kidding themselves and over time will suffer the same effects.
