Bests & Worsts Reviews from Amazon

I live in an apartment in Houston that was affected by our last hurricane. With the 1 year anniversary approaching, my roof is JUST NOW getting repaired. My guest have told me that my place doesn't smell right, I don't smell it, used to it. All I know is my skin and eyes are dry, and I am tired (poor sleep). I have an 800sq/ft apartment. The first day, I moved it from room to room. The air quality sensor would move from red to green, and I could suddenly tell the difference in smelling clean air. On days 2 and 3, I started to have my doubts, so I did things to test the sensor (cleaned the litter next to it, sprayed aerosols, vacuumed, etc) and the sensor changed colors. It detected the chemicals being kicked up in the air and changes colors. I plan on getting 2 more units in the near future. I wish the made a unit the filtered a larger area. I really like that the UV and Ionizer can be turned off, as one of my pets is a bird. Oh, and my friends swear by it too. At first I thought it was a decent investment, but have since been convinced the unit is under price. Their selling factor was the other reviews on here raving about their customer service. I can see why they are willing to issue refunds so readily. Once you have tried it, you will wonder how you did without.
