This air purifier is exactly what we needed to clean the air in our mountain cabin at Lake Almanor, in Northern California. With all of the wildfires this year (Summer/Fall of 2020), we were concerned about the level of smoke and particulates we were being exposed to. With the Bissel Air220 working in our living room/kitchen/dinning area, we are breathing easy. We also bought 2 of the Bissel "MyAir Personal Air Purifiers" for use in the bedrooms of our cabin. We sleep very well with these Bissel products working for us.
