Filter = Air Restriction Any filter restricts air flow to some extent. [URL] There are also metal filters [URL]   Panty hoze stockings for very large ladies and then covering the fan is what I use for a cat filter. It requires regular maintenance to remove the cat hair. Basic cut square  put over fan opening then use duct tape to hold in place. [URL]    
I'll hopefully be ordering a R11 later this month (yay) and I wanted to know if there are any dust filters recommended that I could buy at the same time. I happen to have a cat with semi-long hair that's eternally shedding, so I know it's gonna get in there, as it currently happens with a laptop sitting on a desk (the tower will sit lower, but not on the floor). Thanks in advance for any replies.
Aurora R11, dust filters for the fans?
