I live two floors over the kitchen of a Brazilian restaurant here in NYC. (For the record, I was a tenant in this building long before the restaurant took a lease in one of the ground floor spaces). When the kitchen staff gets forgetful (or too busy) cooking exhaust from the broiler/grill they use overwhelms the capacity of the hood in their kitchen and seeps up thru their ceiling into my apartment. This is an intermittent, unpredictable problem in that I never know when it will occur. I'd like to purchase an air cleaning device to use as needed, to eliminate the acrid burn-off leeching in to our home. Can you recommend something you think would suffice?
Well there really is no device meant to handle that type of load or that could deal with that type of exhaust that one could use. You should really contact your Dept. of Health if you haven't talked with the owner already to see what they could do. The only other item I could think of that might help is to not only do some air sealing but over pressurize your house to help make sure you don't suck in the fumes in the first place - for more on ventilation strategies: http://blog.sls-construction.com/2013/bs4d-ventilation-strategies
