Good air purifier....BUT
on March 15, 2012
While I believe the Oreck ProShield is working well, it is, in my opinion, very noisey. It uses electrically charged plates, when the particles flow through, they are drawn to the plates. When this happens, sometimes (or quite often as I have found) it makes a electrical snap type noise. Imagine a really bad static eletricity pop. That's about what it sounds like. The owner's manual states that when this happens frequently, the "truman cell" needs to be cleaned. I have owned this now for 3 days and have cleaned it twice. There was a thin layer of dust that I assumed was making all the noise, after cleaning, the noise was gone for the most part...until about 4-6 hours later. (Note: It takes several hours to dry after cleaning.) I have this placed in my living room and have to turn it off to watch TV due to the amount of popping noises it makes (about 15-20 pops per minute) I can't imagine using it in my bedroom at night.
Now on to the positive side, like I said, it seems to be working well, the dust collected is easy to see and the cabinet it is placed on is collecting dust as well. Like I said, it IS working, just very noisey. If you plan to use it only when you are not in the area/room/house, then you will have no problem at all. If, however, you plan on using it all day, every day (as I planned) and it is in an occupied room, then this is not the air purifier to get.
***UPDATE:*** I returned the purifier that was making all that noise and talked myself into trying a different one (same exact model)...the new one is SOOO much quieter and is what I expected from Oreck. I have heard the snapping noise once in 4 days of constant use (this is completely acceptable) Now the only noise I hear is the rush of air from the fan, which has 3 speeds so you can adjust it to your liking. The lowest speed is barely audible from a few feet away. I will update again after a couple months of use as the allergy season is approaching (I have fairly bad allergies during the spring and fall)
