Review on iRobot Authentic Replacement Parts - Roomba s Series High-Efficiency Filter, Set of 3 by Dana Johnson

Item described as 3 pack filters for Roomba S9. Received Roomba filters for a different model. Filters are much smaller. Doesn't work in S9. Unfortunately the return date has already passed as I didn't need the filters immediately and kept them until I tried to use them and realized they were wrong.
