Review: Excellent Filter to clean air in a specific area. - This air filter is anazing. This 411 size is large and powerful enough to clea the air in a combined living-dining and kitchen….probably about 500 sq.feet. Even after a year I am surprised when I hear it rev up, even before I realize the need, when I am stir frying something and the steam and aromas start filling the air. I have a smaller one in my bedroom which works equally as well. I bought the filter to have ready but the signal has not yet been given to change. It is almost one year of constant use.
