Don't get me wrong I wish you the best of luck doing this, but I have a funny feeling that if they worked well enough to use for mycology that everyone here would already be using them. You're not breaking any new ground here trying to cheap out on a 99.99% .3u filter and will likely spend more in the long run to correct your current purchasing mistakes.

+1 on paragraphs are your friend.
-1 on the anti-capitalism rant.
Science-wise you can certainly cheap out and slap a bunch of filters together or layer it yourself, but the main underlying point of mycological hoods is to create a true laminar flow. Even if you 'seal them properly' which I'm not even sure what that means - you still have a gap in air continuity which creates eddy currents in the air that can pull air back towards the filter media and draw in contaminants, or adversely create dead space in your airflow. I can go buy a '18x24 - HEPA' filter at Home Depot right now for like 20 bucks... but I would never use it in my lab space other than for a pre-filter.
HEPA does not equal laminar flow. ULPA does not equal laminar flow.
Further, the pleating mechanism/spacing used in laminar filters creates a much larger surface area for the air to pass through than your ultimate output size, thereby reducing the amount of fan force necessary to move the air through at an efficient rate. If you truly think you can layer material better than the current industry standard than godspeed - but I would guess that improper layering will result in a much more restrictive airflow pattern.
You may not like the 'old style filters' but there is absolutely a reason global (that's right, not just America) laboratories and clean rooms still use them... regarding my personal experience with these units I am speaking from many years of experience working in medical laboratory clean room settings at and around the National Institute of Health just outside of Washington DC... The filter for the hood I worked 70 hours a week in cost $6,000 a piece and were changed quarterly...
Nonetheless good luck with your endeavors and let us know how building 10 hoods for the price of 1 works out - I'm sure we'd all love to buy one off of you!

I will format my larger posts more definitively. Sorry bout that. I would go with an FFU unit but I am just fantasizing over the cherry or walnut wood that I imagine custom casing my flow hood in. I would even like to do some electric burns on the wood to give it some slick style points (; After my childish rant on costly filters, I’m just gonna drop $200-$400 or so on a nice 2x4 filter and match a fan to that. In the future I would love to experiment with DIY hepa materials so as to enable poor and low income households to dabble in mycology, But first I am just focused on bringing my business up to full capacity. Still the price of something that is for health should not be so high, and it just beckons at the dominating capitalist world we live in; just disgusting. I will note I just saw a bill pass that enables public schools to integrate hepa filtration for little to no cost to them. What I’m really seeing here is a space and opportunity in the Hepa filter industry to provide competitive price and drive out whatever greedy entity’s are currently holding a monopoly on clean air equipment. It’s like they would rather us live in dirty environments.

I think you are right, not going to skimp on my first build as it is for my business and I just want to do it right. Though I will add expensive doesn’t always equate to quality. I just think something ugly is going on with our current medical field, especially in Amerikah. After I drop an arm and leg on a filter and have elevated my production to my standard I will fall back on a Hepa filter project for DIY. At the bare least I can offer tutorials on how not to get ripped off; if i succeed of course. Maybe it is “impossible” to make a proper filter for less than $500 haha I can’t believe that though. My business launch is not the place to experiment, that would be in hobby land. So I’ll hold off on getting creative for a bit. Hope I can switch things up a bit in the future though. Maybe a filter business is in my hand. I’ve just always been one to provide services and products for an extremely reasonable price. I worked in a jewelry shop for 3 years and have seen what triple key markups do to customers. And it hurts my hippie heart. Just because we can mark something up doesn’t make it okay; and that’s the diff between community driven economies and capitalist corporations that rot the earth.

Machines are probably assembling these expensive units; All I’m thinking is that if some other monkey with a large prefrontal cortex figured out how to get a laminar flow through a piece of filter paper packaged in a box; so can we. Especially if we’re not mass producing them and using our hands and minds combined. I’m having a hard time fathoming that the same company producing clean air devices are polluting the planet in the process; and than charging us asinine prices to clean the very air that they dirtied. Does this make sense to anyone??? Hepa materials should be given out for health reasons. Poor people are forced to deeper into dirty poverty because they can’t afford to put a proper hepa in their HVAC system. If you didn’t read my previous replies; I’ve decided to bite the bullet in this one instance, and purchase a marked up $200-$400 filter, I won’t spend more than that though as it literally makes no sense to me. I’m aware of material cost of wood + filter paper which is normally fiberglass; and those materials are dirt cheap; unless they are sending these cheap materials into space to be fabricated (in that case paying for rocket fuel would justify the $700 price of a hepa filter) I just can’t pinpoint any logical reason for the markup other than monopolies capitalizing, and that’s not logical that’s greed. I don’t have to layer filter materials better than the current industry standard; I just have to do it equally with the standard, and than I can share for FREE how to DIY, maybe it’ll take lots of engineering skills; a fair trade off to not pay half your rent for $40 of materials. I’m sure I sound like a cocky pretentious ass, and maybe I’ll fail and not pull through, but if one things certain, it’s... there’s always a way, if there’s a will. Side rant- this makes me think of our school systems and how they haven’t been updated since the industrial revolution... teaching kids how to be machines was cool hundreds of years ago. Now it’s just outdated. Industry standard hepa clearly works and does not need updating, but why am I sensing a sort of secret in this hepa industry, almost like someone is trying to convince people that they can’t. And the price states that clearly. Dude $6000 for a filter?! You can build a car for $6000. I’m willing to bet that entity paying that price was a government funded one, no? If it was the entity charging would know that and price accordingly, if they were capitalist by nature. Because beauty is in the eye of the beholder and we know that if we can, we will. So it probably paid for those $6000 filters with TAX money, and on top of that, the price to manufacture a filter unless it came from Mars and has rocket fuel priced into final cost; can’t cost more than a few hundred. It’s like why are we paying corporations to make vaccines; they should do it out of the kindness of their human hearts; hope that’s not too hippie of a notion for anyone. I’m just putting together how artificial of a society we live in. Nonetheless- once I get my capitalist supported flow hood built; it is a future passion of mine to experiment with laminar flow applications and I will absolutely keep you guys updated. Seeing as the flow hood is the bottleneck for industry entry; would be nice if an artificially inflated price was not the determining factor. This stretches farther than the myco field though; as I am passionate about clean healthy environments and giving the people the ability to affordably live in such conditions. I’m a mushroom farmer, not a bulk manufacturing facility, I just feel there is this stigma in the hepa field that’s like that of the spoiled rotten trust fund baby. Okay; rant over!

I see some points but I think your ranting is a bit out of place here. Its not as though filter companies have CEO's that fly to space on a whim for lulz. Its a pretty specialized thing that has to be done to a standard and its not like you can buy filter making machines on craigslist.
I looked for some time before buying and found a great deal on ebay for a pair of 18"x48" filters for like $400 new. Each one retails for like $700 or something new. You just need to look around and possibly wait a little bit.

The point was to stoke innovation. If I said how it’s ridiculous that we have technology to go to Mars but don’t bother bringing technology for fresh drinking water to thirsty villages, you would probably reply with “what an idiotic rant.” Way to use vulgar vocabulary; do you speak to your spawn like that? If you don’t like what I have to say you can get upset about it, but it doesn’t affect me. Lol, what’s even funnier is you actually spent time reading my rant. When you could have been developing a cheaper hepa solution. If you think I’m wrong elaborating on how it’s disgusting that something meant for healthcare is so expensive than your probably a capitalist greedy Homo-Sapien; if even. If you care about the value of health and creating a world where everyone could afford healthcare than maybe you wouldn’t be such an ignant pompous persona of a being. Anyways, you probably do everything for money, rather than for the sake of betterment of man. I’m all about bringing technology to the masses, whereas you probably like secrets so that you can profit of the undereducated masses. There’s a difference between us that I’m willing to respect, but I would never direct emotion or disgust towards another human being; unless defending myself or justified as you have given grounds to do so. Just because you like monopolies causing high prices and capitalism doesn’t mean others agree with you...

Appreciate your logical response; I know I was a bit out of place, and my apologies; I could have worded my sincerity for the healthcare industry a bit more differently. I just feel that if the cost was lower for people not even in mycology, but in their own homes, to get this technology in their living space so that they could breath cleaner air and maybe live a healthier life; than it would be a kinder world.
I understand that this is a relatively new technology and will drop in price as time goes on.

I think cheap HEPA filters are just about near the end of the list in terms of things needed to create a kinder world. HEPA technology hasn't come up in any of the philosophy I have yet read. I dont think this is the hill to die on with your issues about the world, seems a tad bizarre actually.
