In anticipation for a large dust kick-up during finish installation, our project is looking into placing an additional cloth filter on the return air grilles (in addition to the MERV 8 filter). Does anyone have any temporary filter suggestions? Thanks!

Wouldn't it be better to increase the MERV rating on the filter or blocking them off completely during the dust producing activities? I'm not sure the cloth would do much or have a verifiable benefit. While you would meet the credit letter of the law with only MERV 8, additional protections when warranted are a good thing.
