This air purifier is great! It is very easy to use right out of the box. You need to open the door in back and take the filter out to remove the plastic. Then after you put the filter back in you can plug it in and turn it on. The instructions are very clear and I liked watching the video that explains everything very well. This machine is amazing. I love that it purifies the air and also has a heat setting. The fan works great and is quiet. I also love the auto mode. It comes with a nice remote that has a magnet to hold it on the top of the machine. This is the first air purifier I have ever owned and I am very happy with it.
