Blueair 211+ Auto Air Purifier for Large Rooms. Purifies 550 sqft quickly. Taken care of while owned, no damage or issues with anything. I simply upgraded to a larger air purifier and no longer need this one. This one may or may not need a new HEPA filter, they run around $60 and you'll have to replace around every year or so. I bought this unit brand new at $350 plus tax. Below is the link for the filter replacement. See Youtube link for purifier info. Text with questions.
