So i found a HEPA Air Filter High Efficacy 99.99 % Particulate Astrocel 24x 24x11.5
Ionex High Efficiency 99.99% high capacity HCX
Description Ionex AstroCel Hepa filter 24"X24"X11.5 high capacity with filter removal clips AstroCel HCX High
efficiency particulate air filter Ionex High Efficiency 99.99% high capacity HCX Filter may be
installed with filter in either direction Ionex P/N 02-230
RETAILS FOR $864.00
If this really retails for 864 then this is a good deal... What do you guys think?
think a 700 cmf fan would be enough?

Yea i know it. But i like the idea of knowing its clean. I hate working in a SAB when i have 50 jars to g2g. even 15 jars is annoying. Agar becomes a lot easier as well, Not knocking on SAB's but if i have the money why not

It's just hard to imagine anyone this sized needing a FH over a SAB if cultivators like Frank and pussyfart are doing as much as they're doing with a SAB and still don't buy a FH. Besides you have to have extra precise sterile TEK to work with a flow hood. They're 99.99% efficient so you shouldn't go into your FH room without having cleaned yourself up. And you have to leave them run before working. It just seems to me like it would make every project your doing take longer unless you're talking mushroom farm scale growing like 100+ jars a week.

I would rather be a little annoyed than to put out money for a flow hood.
I usually G2G 100 quart jars every 6 weeks in my SAB.

I dont think you have to do so much precise. Ive read people leave it running for 30 minutes.
I think the investment for the peace of mind and ease of access is going to be worth the money to me. Plus the resell value is really good! Probably can make money from it.
You know deep down, you wish santa would bring you one.

Not really....
I wish santa would bring me something that I actually need.
A flow hood would not help me in the least bit....it's kinda hard to improve on a 99-100% success rate.

Id actually rather not have a flow hood. I live in an apartment it's pretty useless unless you have a dedicated room for it. And I don't want to have to up my game with sterile technique that much just to use it. Seems like pouring dishes in front of a FH is way more tedious and a hassle than in a SAB Everything has to be precise and within a few inches of the front of the hood. You have to be exacting with your hand movements, in a SAB all you do is avoid having them over the top of sterile media. Way greater free range of motion,

I think your making it out to seem a lot worse then it is. I dont think you have to dedicate a whole room to it and i dont think you need to be as percise as your making it seem. I understand that good technique is good, but there are people that dont even use a SAB and have good results. So im sure theres a little wiggle room with a FH as well.
"For agar work, it's nearly irreplaceable, but for inoculating jars and such, you can do as well with a glovebox, but it's a hell of a lot easier to work in front of a laminar flow hood. I wouldn't be without mine. Bear in mind, you don't want to toss out your glovebox though, because when you isolate away from contaminants you will still use a glovebox. Rule number one is never open a contaminated petri dish or jar, bag, etc, in front of the flowhood or the air will blow the contaminant spores everywhere. RR "

there's way less wiggle room, buy it you'll find out. A lot of people bought a FH as an upgrade from a SAB and that's when they started running into problems.
part of using a flow hood is using it in a sealed room.
A flow hood is like a ferarri sure it can get you to work faster but it's a fuck load harder to drive then an automatic civic with 75HP
It's cool and all but do you really want to do all that before you do your sterile work. Spending a whole can of oust on the air letting it run at least an hour spraying the face of the filter with lysol every time
Quote:
800 square feet is too large for a lab, especially for a small flow hood.
Close off a 100 square foot area or smaller and run the flowhood for at least an hour first to clean up the air in the room. After work, shut it off because you're going to have sealed up your cultures and the flowhood isn't needed until next time you open them. RR

i might be stubbern and not want to listen, but, the filter is going to have the same air coming from it wether it was ran for a minute or ran for 2 hours is how i see it. If i have to run it for 2 hours in a small room just so the air is clean that seems like a horrible filter. I didnt read anything saying that its only 99.99% effective if ran in a small room for 2 hours. So its got to be 99.99% so i dont see a reason to use it like you stated.
The way i see myself doing it is letting it run for a 30 minutes in my bedroom and go for it. Cleaning the work table and such as well but thats it.

it has to clean up the air in the room first so that the air is nearly clean. It's running at 99.97-99.99% the whole time yes but if your contam load is 500,000 particles per square meter after 2 minutes of running you're getting 5000-15000 particles coming through no good. Say you've ran it 1 hour in that sealed room and now you've got 5,000 particles per square meter now you're getting 5-15 particles coming through.
Or you could use a still air box and wait a minute and work in still air and not have to worry about it.
running a FH in a bedroom seems to be asking for fail IMO

RogerRabbit said: That is an 11" filter, which has less resistance than thinner filters. This is why we usually get 5" filters for flow hoods. It's hard to get laminar flow with much less than 1" W.G. of pressurized air in the plenum. Thicker filters were designed for clean room use where they need to pass much more air, thus they have less resistance, but more capacity to store filtered material. Thinner filters are designed for flow bench work. They're pressurized from behind so they'll deliver laminar airflow out the front. They have higher resistance to help with laminar flow and because they're thinner, less debris holding capability. (use a good prefilter) RR

I would look for a thinner filter....
