Amazing, I get almost zero contamination. The best part is the purifier is always going keeping my apartment air clean when I am not using it with the hood part for mycology.
Well clearly since you know everything please explain to me what laminar flow is. Laminar flow (/ˈlæmənər/) is the property of fluid particles in fluid dynamics to follow smooth paths in layers, with each layer moving smoothly past the adjacent layers with little or no mixing.[1] At low velocities, the fluid tends to flow without lateral mixing, and adjacent layers slide past one another smoothly. The air purifier is supplying the air into the let's call it Hood portion. The secondary filter creates the buildup of air allowing it to flow in a stream straight out of my box. The opposite would be turbulent flow which would be the case if I didn't have a secondary filter.
@@HowToShroom I'm going to do my best to refrain from writing a book here, but there's just so much to address. Lets start with, why did you ask me to describe laminar flow if you were going to immediately post a definition? A bit odd, dontcha think? Also, I actually complimented your design for having an actual hood implement, but you felt it necessary to instantly be $hl++y in the first sentence of your response. Nowhere did I claim to "know everything", simply that your design does not produce laminar flow (which it most certainly does not). I must've missed the part in your video where you demonstrated your "laminar flow" with an anemometer, demonstrating how there is ample airflow emitted across the entirety of the filter face, and how there is ZERO variances in said airflow (you know, laminar flow). I also missed the part where you *attempt* to showcase your "laminar flow" with a flame or smoke test (which neither actually illustrate true laminar flow anyway). Maybe I missed those parts, and should do a re-watch.? Interesting how professionally engineered commercial grade FFUs for medical clean rooms, dust-free rooms for electronics, and for plant/fungi propagation don't produce laminar flow, but your unsealed DIY air purifier HVAC furnace filter contraption does. Go to the manufacturer's home page of any of these popular commercial FFU producers, and not one makes the claim of laminar flow for their devices. Maybe these degreed engineers should be taking notes from your clearly superior design? The only place where there is claim that any of these professionally engineered commercial grade FFUs produce laminar flow is from the dishonest distributors using "laminar flow" as a buzzword to market these products. Contrary to popular bro science belief, laminar flow cannot be achieved with a basic cavity and HEPA furnace filter. Achieving actual laminar flow requires: a $hl+ ton of calculations, a specialized filter containing multiple layer of varying membranes and integrated *usually metallic* straws, adequate cavity spacing, baffle placements, among many more requirements. If you truly knew anything bout laminar flow you'd already know this. In closing, what you DO have with your design, is *possibly* a device that provides filtered somewhat smooth constant positive pressure airflow. And, in all fairness, that's all we really need to be successful in this hobby. I will reiterate that I was, and still am, complimentary of your design. I simply do not agree that it provides laminar flow. This isn't shade, merely facts, and no ill intent. Yes, I got snarky with you in this message, but that's only because of how you responded to me, I match energies. I'm more than willing to bury the hatchet if you are. Regardless, best of luck, and Happy Cultivating!
@@WhiteBeardHashtag1205 I think this guy is full of it. He has 2 videos on this channel showcasing his thingamajig, and not once does he even do a flame test or smoke test. I know those arent the best ways to show laminar flow, but at least itll show something. He claims "This is exactly what I've accomplished here" without displaying it at all. Sure bud, we TOTALLY believe you brochacho 🤣
It would be. I use the second filter to creat the build up of air and a more even flow across the work area. My original design didn't have the secondary filter and the air seemed to be strong in one corner but not so much in the other ones. The second filter makes a huge difference. It's just for more even air flow not for actually filtering the air. That is assuming that the air purifier has HEPA filters in it. I've never replaced my HEPA filters after 2 years of using all day everyday. I just vacuum off the pre-filter for the unit.
This is creative and cool, Ill give you that, but this is not a laminar flow hood. Not even close. Far too many people throwing that term around that obviously dont have a clue what it means.
Laminar flow (/ˈlæmənər/) is the property of fluid particles in fluid dynamics to follow smooth paths in layers, with each layer moving smoothly past the adjacent layers with little or no mixing.[1] At low velocities, the fluid tends to flow without lateral mixing, and adjacent layers slide past one another smoothly. This is exactly what I've accomplished here thank you. I do appreciate the comment on the creativity.
@@HowToShroom I know what laminar flow is, and I dont believe youve accomplished this with your "laminar flow hood" at all. If so, prove it! At the very least perform a smoke test. I would bet an entire paycheck that smoke test wont show completely uniform air movement.
Super creative! Affordable and efficient for a hobbiest, great job
Super cool build!!! really great idea!! Thank you!!
So how effective is this flohood?

@@HowToShroom that's amazing! Good to know
This is not a laminar flow hood. You get extra points for creativity and the fact that it has an actual hood implement. But that is not laminar flow.

i find using blu painters tape makes things a bit easier , Thanks ! Great Work ! . these work amazing !!!
I recognize you from Beard's channel. You said these work amazing, youve used one?
The air coming out of a purifier isn't clean enough if i just redirect the air? Great videos by the way

this works if you already have a clean air
Yes but in this case you get a room purifier and laminar flow hood for $200. The hood goes away when not in use the the purifier keeps my space clean.
