Works awesome. I have 0% fail rate on cultures done in front of it. I have thoroughly tested it using the "incense and bottle test" and there are no eddies or vortices.
What kind of "filter" are you trying to set up? My flow hood 'scrubs' about a 2 cubic foot area (the size of my workspace.) For the money if you are trying to do your whole house you can "stack" filters (the purple 3m have anecdotal evidence of being very effective when triple stacked. Many people were using them during Covid. It "purified" the air without damaging the HVAC blower motor)
That's very inspiring to hear!
Do you have a schematic to share? And a parts list, maybe?
Did you pleat the filter material?
“There is a way of manipulating matter and energy so as to produce what modern scientists call 'a field of force'. The field acts on the observer and puts him in a privileged position vis-à-vis the universe. From this position he has access to the realities which are ordinarily hidden from us by time and space, matter and energy. This is what we call the Great Work."
