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

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.

Awesome

Well made.

Works well & is a great value!

Did not use. Air seal around hatch door which allows removal of filter does not seal well. Hot air blowing out around this hatch door

i think this will work out just fine for my laser "ventilation/filtration" system I'm building. I may be buying a second one
