This is absolutely the best air filter I have found for my home.  We had some minor construction in our kitchen,  Sheetrock, taping and sanding. Dust was everywhere.  Installed one of these Filtrete Healthy living filters and the air quality improved within minutes.  I change my filter every season, the Healthy Living filters trap so much dust, dander and who knows what else.  Great product worth the price! [This review was collected as part of a promotion.]
