Omg this is AMAZING!!! I can’t say enough in general about Shark products but this is by far the best. There are soo many great options to tell exactly how clean your air is. There is a setting to tell when to change the filter. What I love is that when I cook or burn candles or vape, this thing kicks on and cleans the air until it’s at 100%. It’s not too loud and doesn’t take up that much space. I even tested it out to confirm it was cleaning alll the air in my house and it was! The only downside is you do have to keep it 3ft from a wall so depending on your layout it could stick out a bit but at least it looks really nice.
