AIRWISE PURIFIER For Small Rooms

I had high hopes for this unit, based on its advertising. However, it failed, as have every other air cleaner, in eliminating noxious fumes from disgusting meals, cigarette odors and other toxic substances smoked, cooked, or whatever, which residents of my housing complex consume, and which come thru my vent system, even though I have blocked the vents off. This unit, as far as I can tell, is a total waste of money. Had I purchased it though the manufacturer, I would have returned it a long time ago, but since I bought it through amazon, I think I have to cut my losses. It does NOT eliminate any odors, nor have any of the other air cleaners and purifiers I have run through in my 13 years here. NYC is a toxic waste dump, and I don't think any air cleaner will help with my situation, located in between two major highways and an airport, with drug dealers and cigarette smokers on the premises. It may work in a less urban area, but then, the air would likely be better and not require it. My kitchenette is 6' X8' so qualifies as way more than a "small room." It also has no window, so I had high hopes for this, but they have been dashed. My advice is save your money. I wish I could move,. but circumstances dictate otherwise.
