This shark air purifier was extremely easy to set up.  Remove it from the box, remove the plastic from the filter, plug in and you are all set. I love that it tells you what the clean air percentage is and how long it will take to get it to 100%. I set it on auto and let it adjust the speed as needed to clean the air. I can really tell a difference after cooking.  I would definitely recommend it to my family and friends. It works so much better than others I have had in the past.
