the sharp af-s120mx air conditioner is really good.i use it to keep half of my house clean.but, it runs up electricity a little to fast for me.And its really hard for me to clean the filter.It takes me about 10-15 minutes.Plus it is a little to quiet,dont get me wrong but sometimes i like to have a little noise so i dont get a little suprised when my friends try to freak me out.but all in all,it deserves 4 stars!!
