I received a complimentary Levoit Core 200S Smart True HEPA Air Purifier in exchange for my honest review. 
This Air Purifier has made a noticeable difference in the air quality in our home. My husband and children suffer from allergies and all that go with them,  itchy, water eyes, stuffy nose, etc.
I set this purifier up in our living room and in a short time, I noticed a big difference in the way my family felt. I love that it is smaller and aesthetically pleasing, so it will look great in any room. The app is great, because it allows me to ask Alexa to control how I use the purifier.. The white noise is at a level that is acceptable and not annoying, and the night light feature is awesome, allowing just enough light to navigate with. I highly recommend this!
