After spending so much time at home we were realizing that we needed something to mitigate all the kitchen smells, dust etc in our apartment.  I was skeptical at first about an air purifier, but upon a recommendation from a friend, I chose this one.  It's been great!  The automatic setting works really well.  We have this in our kitchen/living space and it does a great job when things get smokey. It's also greatly reduced the amount of time other scents linger in the air (e.g. cooking bacon) and makes the environment fresher.
