I did about 2 years of research on air purifiers before I bought mine and I decided on the Freidrich C90B. After I got it home and let it run for a few weeks I knew I made the right choice. You have 2 options really. You can go with a Hepa unit or electrostatic.
The reasons I chose the freidrich electrostatic one over all the others were;
1. Easy to clean (just put the grill inside the dishwasher and it comes out clean. 6. Does not produce much ozone compared to others.
I am a smoker and this unit does an excellent job of pulling smoke out of the air. I have had many people come by and had no idea that I smoked indoors until I told them. Usually you can tell but this filter takes the smell right out. When you look at the collection plates, you can see the yellow and brown particles and dust on the grid.
Beware of those as seen on tv ones. I dont know if I can say here without getting in trouble but the sh*rper image ones are a not great imo. There was a lawsuit between them and consumer reports because CR found their units did not work as advertised and produces excessive ozone which can be harmful. SI lost the lawsuit and had to pay CR. The Or*ck ones are not that good either from talking with other people. Pretty much avoid any you see on tv.
