I'm coming up on a month and will be cleaning the filters so this review does not include that.  I'm hoping it will be easy to accomplish and appreciate that the filters can be washed and dired rather than replaced.  I love the adjustable fan speed, too.  I have really noticed a difference in my allergies with this unit in my apartment!  It's also very attractive and can easily blend into its surroundings.  Others I have seen seem to stick out, usually due to the UV light.
