This thing has been such a game changer in my house. My mom is on oxygen so it’s important that the air quality is clear in the house especially with also having two cats and this thing has let us know when any issues arise. It’s super quiet like you have to go near it just to hear anything and feel the air coming out of it. It’s lightweight and not bulky and just overall does the job. Even when cooking and it seems like the smoke gets too much from frying oil it will let you know immediately that the air quality has dropped in the house. I love this so much!
