Also it's best to work right after a shower where you've scrubbed your arms a little. Mine are usually a little red when I'm done.

Just keep yourself. Clean and follow the same kind of sterile procedure you would when using a flowhood.

Smooth hands will take you far.

As long as it filters 99.9 or 99.99 HEPA effeciency it will work.

Some of them come with a 'regular' filter and you have to buy the true HEPA one separately so make sure you know which filter it's coming with.

Ya that one says "Hepa Type" and it does not say anywhere its 99.99. I found a true hepa one that's $10 cheaper. It seems like you could lay it on it's side and use it still...

don't make the mistake of leaving your hepa in a dirty car, dirty house, area where people smoke. most of the people who do have problems cause them. by not thinking with common sense about things like that.

and everything et said is good advice.

The reason a flow hood works is because the sterile air is blown in laminar flow. Contaminants get trapped in the laminar flow and are pushed out instead of falling down into open sterile containers.
If anything comes between the HEPA and your open container contaminants can get blown right in.
Its not enough that the air is sterile, it only works if blown in a laminar flow.

This is funny because 90% of the furnace blowers attached to a HEPA filters on here don't actually create 'laminar' flow.

Is there always room for error? Yes. But my experience tells me that clean air DOES equal clean work.

A HEPA unit attached to a box might just do the trick. But the bag gives you so much more freedom to move and it's basically sterile just from it's manufacturing process.

Yes there is always the possibility that contaminates may be stuck to the sides of the box. But most box work always begins with misting the walls.

Sorry if this has been asked, I didn't want to read through pages and pages to find if it has, could I get a Large tote, cut a hole sized for a purifier, silicone it in place for no leaks, and make sure in take is fully on outside, and outtake fully on inside, then have my holes just like a SAB, would this have the same effect as this Shmuvbox? I've always thought about it. and now after seeing this I think it may actually work. Thoughts? Would basically be a permanent shmuvbox that you wouldn't need to assemble every damn time you want to work, shmuv seems like 1hr+ prep work just to work for sometimes half an hour. seems like a big waste. So why not make it a permanent fixture that you can just put in a corner until next use.

Would be same idea right, air flows out the holes blowing out all bad air out and purifier will fill tub with clean air.

i built an old SAB type setup with a hepa unit attached. its a pain in the ass to build, (i used the stuff for sealant) it also is big and bulky and hard to hide. the hepa, folds up in a small space. and everytime you take a brand new trash bag out your using a fresh bag. one of my favorite aspects of the shmuvbox is stealth. i find a 55 gallon clear lawn bag far more spacious than a 110 quart tote. even though that is a large space. i can only comfortably fit about 15 quarts in it with room to work with. whereas, in a 55 gallon bag, i can fit 40-50 quarts at once. so i can do all my work in one sitting. i don't have to wipe down a bunch of jars. inoculate them. then remove them. then wipe down a bunch more jars, inoculate them, then move them.

i can wipe them all down in a row. place them in the shmuv. then do all my transfer. and bam take them all out and label. all in a very efficient and factory like method. like an assembly line.
