## Description

8" Inch Filter Replacement - Round Duct Filter System - G4 Class Filter and Mesh Screen - Dust Collection and Air Purification - desertcart.com

Review: Great for my use - Perfect for my needs. Good quality, shipped well and I think they’ll last. I don’t think I’ll need to replace the filters, I’m using them in a clean room environment. I’m using them to stop a wipe, rag or loose piece of plastic getting sucked into my fan. My air flow dropped by 100 cfm, I was able to increase the fan frequency to compensate. Great functionality and ease of use. It’s a little less than 8” which makes installing the wire ribbed hose much easier. A true 8” union is very hard to install. I’m using it on the intake side.
Review: Works great - Awesome
