I purchased the PureZone Elite air purifier from Menards a month ago. I truly love my new air purifier. I have terrible allergies and this air purifier has helped emensely. It's quiet and I sleep better at night. It's simple to use and lightweight so I can carry it into the bedroom before going to bed. 
                    I use the automatic mode. I was cooking bacon and it automatically turned the fan on high to clean the air. I couldn't be happier.
