I really like this little air purifier. I had never used one before but am glad I have one now. I keep it in my living room and it has done a great job at keeping my allergies at bay. The weather where I live has been so windy and dusty but the purifier keeps the air clean and sanitized. It was easy to set up and is compact enough that it doesn't get in the way. I really love how quiet it is and that I can set a timer on it. It's a great little device.
