Thanks for your contact. We guess that the motor of the air purifier was damaged for improper transportation of the carrier. Please don't be worried about that and this case is not a common one.
You're our valued customer, please send an issue video to our support email to further investigation. Once we checked, we'll resend a new item to you right away.
As for the filters, the green filters include all the benefits of a pet allergy filter (original filter) plus a custom toxin absorber filter to effectively absorb strong smells, air pollution, cigarette smoke, vehicle exhaust, VOCs, and other harmful gases. You can make a pre-order on our website.
Again, we sincerely apologize for the great inconvenience!
Any other needs or puzzles, please feel free to tell us; we're really really glad to serve you
Best,
Support@okaysou.com
