I am in love with the Shark Air Purifier 3-in-1 product! I honestly don't know how I lived without it. Its ability to adapt to heat and cool temperatures is wonderful. Noticeable difference in the amount of pet smells and cooking smells with this in place. The air is cleaner and safer. I love the fact that when having a larger group of friends over that it automictically does the work of keeping the air purified. A wonderful product that is easy to use and has so many benefits for you and your family!  I highly recommend this product!
