Do they make a return air register with room for an air filter? The
registers in my house are one stud space long - 16", and about 8 - 10"
high. Thanks.


Mcmaster-Carr sells them. http://www.mcmaster.com page 601. I'm not sure
they are available in the smaller sizes. You better make sure you can find
the filters to fit before you buy them. As others mentioned it will affect
the balance of your system as the filters do restrict the air flow.
