If the pandemic and having to work from home has taught me anything, it's how important it is that I breathe (constantly) needs to be clean and fresh. I purchased this, not knowing what to expect, but within a few hours of running it on high, I could tell a difference in how I was breathing and the smell in my house. I have single pane windows (old house) and it seemed the exhaust fumes from outside, mixed with my pet smells, would overwhelm me at times. But my house smells much fresher.The product arrived quickly and was well packaged. When the product is on high, it does sound like a fan on high speed (a little louder than I like, personally) but it's not overwhelming. I like that it automatically senses the change in air quality and the lights change to let me know air quality has declined in the home.The sleep function is awesome.Highly recommend this prodcut.
