We have been using the Fresh Air Globe now for just 2 days. Already there is a notable difference. My girlfriend is allergic to our cats, and uses an inhaler. Since we started the Globe running she has not needed to use her inhaler anywhere near as often. She also sleeps through the night without waking to need to use the inhaler. I am very happy with the product myself, As I have house cats, and as much as I do stay on top of keeping the cats clean, I always feel a smell lingers. Not the case any longer as the Globe seems to do the trick when it comes to clearing lingering smells. The 2 scents we received were Lavender and Eucalyptus. The eucalyptus was quite nice, and gave the room a sense of freshness.
