My family has been using this product in our main room now for almost a week and so far we have been pleasantly surprised with how efficient and quiet it is! The 3 modes is an added bonus allowing you to pick between purified air, purified heat, or just the purified fan which is amazing. It comes equipped with an easy to use control panel, and seamlessly tracks and adjusts to the quality of air in the room. 100% would recommend to anyone on the market for a high quality, efficient purifier!
