I got the Shark Air Purifier MAX 3-in-1 with the air filter and I love it! It is a tad bit larger than I was expecting but it is good because it works amazingly. I love that the remote is connected by a magnetic and clicks right back in so you do not have to worry about it moving around. The instructions on the machine when you first get it is great to help you learn and get started. I am still learning all the parts. The heat and fan works great! I love that it rotates and helps heat or cool down the room. You can smell the room having clean air now! I would definitely recommend!
