I am truly impressed by the quality, design and functionality of this air purifier. This honestly could not have come at a better time. Usually during the spring I suffer from allergies that just make me miserable. Since I have started using this I can really tell a difference in me and my home. I love that the filter on this purifier captures up to 99.98% of particles leaving the air in my home feeling clean. I like that this is compact and quiet but purifies up to 500 sq. ft., which is perfect for my bedroom or living room; I like that I am able to easily move it form room to room with me. I would definitely recommend this to anyone who is looking for  a compact, well made purifier from a well known brand as you will not be disappointed by this one.
