HEPA Air Purifier for Large Rooms

My first impression was positive – it arrived neatly packaged and was easy to set up. After using it for a couple of weeks, I noticed a real difference in how the air smelled, especially with pet hair and odors. It's not perfect, but for the price, it does a decent job. I'd recommend it to others looking for something reliable without too many bells and whistles.
- Pros: It seemed to handle large spaces fairly well, making the air feel fresher quickly. I liked that it adjusted its speed on its own based on how clean the air was, which was helpful. The light showing air quality in real-time was a nice touch, keeping me informed without fuss.
