So thankful to have gotten this Shark HP102 Air Purifier with True HEPA, Microban Antimicrobial Protection, just in time for allergy season. This Shark HP102 Air Purifier has been my savior. Although the air purifier is quiet, it is a powerful air machine. I have four dogs that shed, plus all the pollen outside sometimes makes it impossible for me to breathe. Thanks to this air purifier, I can wake up breathing easily. Excellent quality, easy to use, and best of all, its great design allows you to place this anywhere in the room without making it look like a bulky air purifier machine. Love its performance and that is why I highly recommend it.
