ionic breeze air purifier bathroom

Recommend a good air purifier / cleaner that cleans the air very good, especially CIGS smoke?

I live in a 1 family house with 2 floors without the basement. I have 3 rooms upstairs. The 3 rooms are next to each other as a triangle. My dad sometimes smoked in her bathroom, in your room. my room is like 15×15. My cousin is currently sleeping in my room at the time, so its 2 of us in the small room 15×15. So you can imagine the amount of dust and Oder body and smoke in the small 15×15 room to sleep in. I do not 2 months of research on purifying air and cleanliness. Many people say that Ionic Breeze purifiers are best. What I have read and what someone told me, is that the ionic air purifier negative emissions ions and contact with dust, the dust becomes too heavy and falls. This is my main concern about buying a purifier of the Ionic order. If the powder then falls my bed and have my library and other things in my room. I know what everyone's opinion about air purifiers and you recommend one for my 15×15 foot room squares.

Criss: The Ionic Breeze is an ionizer and produce uncontrolled amounts of ozone. Ozone is harmful, not to breathe. I'll send a link to an article on how to select the right type of cleaner air for you. After reading it, you'll have to look more square feet (something that never I thought), but also have to look at ceiling height. A filter for air conditioner or furnace is only going to work if you are running one of the two. I do not know about their place, but in my position does not always have one. Personally, I like the HealthMate, but make only one of the chemicals as the smoke of the so-called super HealthMate. Too bad that not only may be asked to leave smoking.
