Time for a Home Refresh! I just got this new Air Purifier & I cannot get over how much I LOVE Smart devices. Not only do I get alerts when the device detects bad air quality, but I can control everything right from an app on my phone. This also will alert you when the filter needs to be changed/cleaned. I mean come on…as it gets into allergy season, this is a no-brainer!! LTKWatchNow LTKHome LTKSeasonal
