I purchased this air purifier close to two years ago. I love it but had a minor issue with the filter light not resetting. I called customer service and they took care of the issue for me.. Pure Enrichment has a great warranty so you can always depend on this company to stand behind their products. I want to say that I own the Halo purifier also and love it as well. I also have their humidifier. All are great products. Thanks to this great company!
