I have just begun using the Honeywell Air Purifier. I am using it in my family room where we have a pellet stove and want to have good quality air there. This unit is good for a large room such as mine and I like the nice sleek design. It has a touch screen LED control panel on the top and has 4 cleaning levels plus a turbo setting. Love that it has a HEPA filter that should last 1 year. Also has a carbon filter that helps trap odors. You can dim the control panel if needed and has a auto-off timer option.
