This device is great, the room air sensor is highly sensitive. When cooking it detects odors as well as air charge to filter the air and give no odor and costs. Experience with a squeegee, we have not had to suffer a lingering smell ... Opening a window is detected by both dust / pollen and other fine particles pollution, the indicator turns purple, then pink, and finally to red to activate a filter maximum volumes air as quickly as possible. Being sensitive to pollen, I encourage the setting of Ultra-sensitive sensor on my allergic rhinitis shows me good efficiency. No more symptoms when I'm home.
