Feng Shui Air Purifier Ionizer?? in my feng shui book, it say "no ionizer" "no purifier"...

in my feng shui book, it say "no ionizer" "no purifier" for the bedroom (and I am assuming this would be the same for the unharmed house).

the only point that i can figure is that it sends negatively charged ionized nouns into the room, so that's bad chi? or is it because it's too "yang" beside the motor and blowing air and so forth.

i hold an ionizer/air purifier, i spent probably $250 on it and yes it's in the bedroom. i don't want to draw from rid of it, can i use it in any other room of the house? or should i really draw from rid of it? or was my book wrong around that?

i don't need it for smoke or anything severe. but i live within a construction zone right now so it help alot. i'll be moving in two months and not contained by a construction zone, so i don't anticipate really needing it, but it is soothing to sleep next to the white noise and the upper air is fresher.

sorry for the long long question.

thankfulness!
Answers:    Keep your purifier, you need it. Feng Shui books tend to be deeply black and white on some things. As long as you follow the generaly principal of feng shui you will be ok.
put it next to your heat air intake.
