Hello all, We are in the midst of a long and dirty side return extension on our house. We moved out for two months of the work but now face six weeks in the house with the builders. We have two children, a third one on the way and a massive amount of dust in the air. I was thinking about getting an air purifier to try and cut down on some of the dust in the air. I was wondering if anyone had an air purifier or had used one for this purpose and could give me any brand or type recommendations.
