Save yourself the trouble and order it here. http://www.fungi.com/tools/airfilters.html
The filters are designed just for mycology and all the spec's on the filter are posted. It's 99.99% efficient. The smallest filter is only $89.95.

I've looked into buying one already made, they're too expensive, the cheapest one i saw there was $530.00 and it's really small.

They don't hgave the size I want either.

Exactly. Just the filter. I bought the filter that cost $129 dollars. I was able to grow several pounds of cubensis dry weight in a month and half from that filter. You wouldnt need a bigger filter than that unless you were a commercial mushroom farmer.Why wouldnt they have the size filter you need?

I think he just doesn't realize they sell individual filters, he looked at the website earlier and only saw flowhoods.

Thanks for the link though, now I know where to go when I want to buy a reliable filter.

That is actually the long term goal.

I had no idea Fungiperfecti sold filters, I'll have to look more, I guess the sell the matching blowers too?

so the all-purpose blower for $179 on this page: http://www.fungi.com/tools/fans.html


& the 12X24 hepa filter on this page: http://www.fungi.com/tools/airfilters.html


plus some wood, and screws....and you've got a flow hood?
is it really all that simple?


& is 12X24 a decent size for bags?
because g2g with bags would be amazing.

Make it air tight.  You don't want leakage of air around the HEPA filter. Build a plenum at least as large as the filter, to equalize pressure on the back side. That blower and filter combo should be fine.  You might end up wanting a motor speed controller, as about 200 cfm to 250 cfm is what you'll want out the front.

I do LOTS of large spawn bags with a 12 X 24 flowhood, about 4,000 in the last three months.  You do G2G with the receiving bag laying on its side to keep it in the sterile air flow.

very interesting.

it's time to start saving my pennies, because i would love being able to work outside the confinements of a glovebox. i'd feel so much more safe doing agar this way too.

Don't forget the pre-filter.  It will make your expensive HEPA last a lifetime of hobby use.

pre-filter?

what would that just be the same filter, but behind the original one?

No, It's a furnace filter in front of the blowers intake to keep large particles like hair and dirt away from the hepa filter.


Does anyone know if it matters which direction the blower is facing, like does it have to blow towards the filter or can it blow against a side wall or something? I'm not sure if it would make a difference or not it doesn't seem like it would since it's air tight and building the same pressure.

No, they sell them at all the *mart places and supermarkets.  Something like this

I use a small 12x12 one.

As for the way the blower is blowing, you want it blowing NOT directly at the filter.  You want the pressure that builds in the plenum to be the driving force of the air leaving the face of the filter.

Sorry, I'm confused now... I just thought a plenum was a little plate (like dinner sized plate thing) that you would place under the blower output (assuming your blower is pointed downwards)... how do you fit something as big as a whole side of the flow hood into the flow hood itself?

Re: Need help building a flowhood. [Re: DragonChaser]

The "plenum" in your flowhood is just the inside of the box that is not the filter.  So say your HEPA is 8 inches deep, you want your box to be a total of 16 inches deep, so you have 8 inches of empty space, aka the "plenum," behind your filter.  The blower blows into the plenum, creating pressure (which is all happening behind the filter, in the box) and what happens is when that pressure becomes enough that the air in the plenum (your box) is forced through the filter.  This pressure is what creates the "laminar flow" of sterile air.

OK, I got them in the mail, I ordered a 18" x 24" filter and the universal blower, now I'm trying to wire it and I just want to make sure I got it right, I've also been reading this thread with the same blower.

I figured on my own that the black and blue go together and connect to the black on my 2 prong cord, the white is by it self connected to the white on my cord and the orange and red go together and are put aside, is this correct?

Also the manual and everything stresses it needs to be grounded somehow, there is a half green half yellow wire coming from the motor housing going to the blower output area screwed into it and theirs a ground symbol sticker next to it, so is it safe to assume that it's already been grounded for me or is there something else I need to do?

I really don't want to blow this thing up the first day I get it :lol:

E: I'm reading more threads and I'm starting to get confused, do I need a special plug or something?

Hmm, Will I need to put duct tape or something over half the intake, FP for some reason say they match but in the thread above RR says it's way to big even for a 4' x 4'?
