Inquiry (采购产品): Carbon Filters I have a roof top unit used for a surgical center with 6 24x24x12 HEPA filters and 12 20x20x2 pre filters. I want to replace the pre filters with Carbon to help with a smell. What type of pressure drop will I have with your filters? I want to ensure I don't over work the fans. What will 24 20x20x2 carbon filters cost me.
