| Before you build a FLOW HOOD.
Go to any large automotive store & look at Fram, Purilator and/or any other high quality automotive engine air intake filters. They come in all sizes, thickness & shape (round & rectangular) & for trucks, there are canister style ones.
They are easy to adapt as PREFILTER in front of, or on top of any HEPA filter. They don't cost much, are high volume & the better ones almost filter down to near hepa quality filtration (as in 3 to 5 microns).
One of these puppies with almost last you a lifetime. Moreover, if you ever want to replace one. All auto parts stores have them. On top of that, they are not generally -- spendy.

| Do you have a preference in model? Also, can you suggest a method to mount or adapt the auto filter to a hood similar to 420M's design? (fittings used etc.)

No particular preference in make, because everybody's budget differs, as does the design. Round ones are easy. Any auto intake air filter for any big V8 is best. They all have some sort of rubber seal top & bottom.
Simply size the hole on top a bit smaller than the filter you choose, so that when you set it over the hole, it will create a seal. Then cut a piece of plywood (or any hard material) a bit bigger than the size of the top filter, with a small bolt hole in the middle.
Then use anything stiff (one inch angle iron, wood 2 X 2) with a bolt hole in its center & a bit longer than the underside of the opening. Then use the threaded rod or bolt & nuts to sandwich the filter between the two. Then, you tighten the top nut to & sandwich it all together - tight.
The top is solid, the 2 X 2 underneath gives it lots of air space, to draw through.
LOL, crude description, but I think you can gather what I mean, by it.

| I use a cannister type filter, like this one. It is about the size of a gallon jar. Mycota

|Looks like you took it to get it's picture taken, like you would your kids.|

| I kinda get what you are talking about, but only halfway.
Could you be so kind as to provide us with a picture of how you constructed this flowhood?
I really want a flowhood, but am quite unable to afford to build one.

Just follow the "420m Build A Flowhood W/ Picts " thread. Look at the diagram of the flow hood. It is a simple design & easy to build.

| Oh - yeah - sure Mycota . . .NOW you start a thread entitled - to anyone who wants to build a flowhood.
Just Kiddin my friend :-)
I know EXACTLY what you mean! - Can't WAIT to fire it up and get my first clean cultures going!
BTW - I am going to make those changes to the plexiglass size (for more hand room) and the pre-filter attachment.
Ummm - how much space - DO you think I should have for hands and equip? How much is too much? Sorry if that sounded silly!

|8.5 to 9 inches is about right -- for me. Set in front of it with a quart jar & judge for yourself. Mycota|
