Coway Airmega 400S Smart Home Whole Room Air Purifier with HEPA Filter, White

This unit services our open concept living room and kitchen. The dimensions are about 20x40 feet with 13 foot ceilings. The smart setting raises the fan speed when we are cooking despite have an exhaust hood running above the stove. It does not take long to settle back down to its lower speeds. It has a large footprint, and its suction points are on opposite sides so you'll need clearance around the unit as well. The app is not as bad as people make it out to be. Maybe it used to be, but my setup and use have been near flawless. I do get unstable connection notification on occasion, but we have a very dense network of IoT devices. I do wish the reports were searchable via hovering over data points, so I could pinpoint times high readings occurred.

We live in the Sierra Nevada Mountains of California and go through months/weeks at a time where the smoke from forest fires can result in air quality in the 700-800's. What a game changer the Airmega is!! I wish I had ordered the Airmega 400S sooner! We love that it covers the entire house and is extremely quiet. Between the cats, dogs, forest fires and pollen, we were in need of cleaner air. If you are still trying to decide if an Airmega is worth getting, then wait no more! Order one today and you will not be disappointed.
