I was doing some research on this air purifier this is what i found...
"As a bonus, these air purifiers can also protect your bird from YOU! In addition to removing airborne particles, each of these units has a large amount of activated carbon that absorbs odors and chemicals. Many household items such as bleach, tobacco smoke, cleaning solutions, etc., can kill your bird. Over-heated Teflon is extremely toxic to birds and small animals -- and it isn't good for people, either. While there is no guarantee that toxins will never reach your pet, the significant amount of carbon in these air cleaners will remove vapors much faster than inferior units with minimal or non-existent amounts of carbon"
