The setup of the Shark air purifier out of the box is very simple, all you have to do is remove the filter from the packaging and then power the air purifier on. The unit itself is small and lightweight which makes it easy to carry around to different areas of the house. When the air purifier is on it is very quiet you won’t notice that it is powered on. The feature that I like the most is the panel that shows the air quality percentage. I keep the air purifier on auto mode 24/7 at the top of my stairs near the kitchen and whenever someone is cooking in the kitchen I can see the air quality percent decrease and then the air purifier will kick in and start to clean the air until it is back to 100%. This is a wonderful product and works great.
