Review: These are perfect for my ghetto Air Purifier - I was amused by the fancy packaging for a rubber clamp, they even thought to use a foam insert to prevent deformation. The clamp fit my Vortex Profilter flange snugly, but was actually a bit loose on the AC Infinity Cloudline S6. A little pre-tightening of the clamp prior to insertion solved the issue. These really simplified the process of building my DIY Air Purifier. Review: Beste Anschaffung - Günstig, passt wie angegossen.
