My Flowhood is Complete
    #26895298 - 08/23/20 11:57 AM (3 years, 5 months ago)

After weeks of research, countless emails, so many headaches, hundreds of dollars, a few moments of sheer panic, two small wounds, 13+ hours of construction, and TONS of help from this community, here she is:



Now I'm just waiting to get the 15 x 15 prefilter in the mail to go right on top. Hopefully this is a game changer, it took so much to get to this point.  Now I just need a desk or a little table to put her on.  Anyone have any suggestions? (she's 15.5 inches deep)

Thank you to the shroomery community!

Congratulations! I hope you enjoy it and get lots of use isolating and researching with much better success.

Pro Tip: don't use near walls.  I find its best for it to be center'ish in the room when using.

Thanks Fungi.  I was actually going to set it up inside a closet. :lol:
Not totally inside like a walk-in closet, but placed inside the closet blowing out into the room.  I could just pull it out of the closet instead and use it in the middle of the room, it is a small room however.

It damn sure wasn't cheap.  Finding a cheap HEPA was impossible especially in the 18x24 size that I wanted.

HEPA $330
Blower $150
Wood $96 - cut perfectly to size for me
Home Depot $160ish - includes a jigsaw.

Around $740 total.

Thank you Jcm.  If you've already got the blower just keep your eye out for good HEPA filter deals, maybe even purchase one locally for a better deal?  I've heard of people doing that but every place I called would only sell me 6 at a time or some BS.  The one lady thought I was trying to use it to protect myself from covid 🤦‍♂️. I don't know about your blowers but mine isn't nearly as loud as a vacuum.  I'm very excited to get the damn prefilter so I can give this thing a go.  Guess I should watch RR's videos again and learn some technique while I wait.

I finally found out the wall introduced  some turbulent flow or created a vortex that pulled dirty air into mix with laminar flow is what I finally came to believe.

I recommend you take a few agar plates and test it in the closet and then the center of the room and compare for contaminates.

I mentioned it because it is something that set me back a lot of hard work till I figured it it.


It was after watching a video by this little redheaded dude creating a wing by 3D printing a U shape in the wing for the prop creating a super massive amount of lift almostmakesit a virtualtakeoffandits stall speed was like 2mph it was a real design and works).
I don't remember how it gave me the idea that maybe bacteria was being sucked into the laminar flow but it did. Then I did arag plate tests and found out that bacteria was in fact being pulled into laminar slow creating turbulent flow and fucking shit up Sirius, Lee or whatever your name is.

I know this is a bit late, but maybe anyone else interested can take advantage of this. This site sells HEPAs of all different types and configurations. Here is a 24x18 for $123, https://www.spycor.com/99-97-HEPA-Filter-Wood-Frame-24-x-18-x-5-7-8-p/magpb2418a5a.htm?CartID=1 its about $150 after shipping depending on where you are. They also sell prefilters.

99.97

You'll want 99.99

I've read that 99.97 is good enough. But if you're right you're right, I don't know for sure. Either way here's one https://www.spycor.com/99-99-HEPA-Filter-Metal-Frame-24-x-18-x-5-7-8-p/maggb2418a6ax.htm still cheaper but not as good of a deal. If you don't need that specific dimension they can be found a bit cheaper too.

I guess in theory 99.97% at .3 microns isn't good enough. But I would think that .02% is small enough that you are still extremely unlikely to get a contamination. But I don't know because .02% of billions of particles is still a lot of particles. I would have to test them both side by side with open plates to see contamination rates, so I won't say anything definitive.

Heres another 99.99% from another site at $177 before shipping, https://damnfilters.com/collections/hepa-and-other-high-efficiency-filters/products/hepa-filter-24-x-18-x-6-600-cfm-99-99-particle-board

Bear in mind that the efficiency of filters is only measured at 0.3 micron. Actual performance is different depending on the size of the particles. Unless every single contaminant in your room is exactly 0.3 micron, making estimates based on the two filter efficiencies @ 0.3 micron is not useful. In general, smaller and bigger particles are both easier to filter.

Interesting. So what does that translate to in real life? I'm not familiar with air filtration at all so I don't really know what that means. Are you saying that the percentage doesn't actually represent the filtration capabilities in real applications? Which would you choose?

Thanks again for the info Fungi.  I will definitely be doing some test plates.  Those are some good deals Kernale but keep in mind that there's a 4-5 week lead time on those Damn filters.  I went with Fungi Perfecti and I know they overcharged, but I will say that the all metal frame was a dream to work with.  The filter is actually made by HEPA Corporation too, I had a lot of questions and the rep from HEPA was a GODSEND, I cannot say enough good things about HEPA Corp.  Fungi packaged my filter perfectly and had it to me from the other side of the country in just over a week, not a single aluminum fin was bent.  Definitely don't buy the blower from Fungi though 😅.  Got a generic Dayton from Amazon.

I would probably do the same, its still a good price for a filter and there's something to be said for the convenience.

I mainly meant not to pay too much attention to numbers based on 99.97 vs 99.99. I've seen some people guesstimate a spore load and work out how many more they'll get through with 99.97, and translate that through to some figure about how many more plates you'll lose or whatever. That's basically just wishful thinking presented in a scientific looking way.

AFAIK most spores are larger than 1 micron, e.g. trich is 3-5 micron. A full order of magnitude larger than the rated 0.3 micron efficiency. Which again (AFAIK) is a size chosen as being a difficult task for a filter- bigger and smaller particles are both easier.

At the end of the day, you can ask here as much as you want, and will get recommendations either way (though mostly to the 99.99), but I don't believe you're going to find anyone with direct experience with both, and also a clear conclusion as to which is better.
