What do you do to sterilize the face of the filter and work surfaces? How long do you let it run before working?
you really should leave them to run constantly IMO. at least that's what the pros do.
True but unless you are using it every day the odds are not likely. I don't leave mine running 24/7. So I spray down all surfaces including the entire filter face with alcohol from a pump sprayer and let it run for 30 minutes prior to use. I also bang a few times on the work surface after turning on the blower to help dislodge any dust that might have gotten into the work area while it was off. When I was doing orchid tissue culture my contamination rates were 3-4% so it doesn't need to run around the clock.
alcohol does absolutely nothing to clean in front of a flow hood. it needs a few minutes to work and it evaporates in probably less than a minute if the flow hood is blowing air.

Letting your flowhood run 24/7 so the workspace and filter front are always sterile. I was thinking after drake mentioned it, i might use one of my small 26 cfm blowers to run 24/7 off my big flowhood filter to keep my future lab clean. One issue with running the big motor is your compressing air which makes heat.

And drake, your 100% correct rubbing alcohol will do nothing. The man reason is that rubbing alchol is just that, you need to rub it to break the organic cell walls. There are spores that can withstand an alchol soak but not a rub. And theres no way to rub down your filter face.

If I do that in current set up I'll have to change my HEPA every week. How often do you guys change pre filters. And Drake are you indeed running the hood without the prefilter. Must be fucking clean at your farm.

No way man I sometimes think there's small holes in it haha! I got grain and sawdust all over the floor a lot of the time. But yes I do run with no prefilter. It's a 12" thick one so probably more surface area than the 3 or 4" ones. I use lysol as my main sanitizer but I still use alcohol on my hands since it dries.

as long as it lasts seems like a good answer. i buy new-old-stock filters all the time, like 10 years old from nuclear reactors that never got finished. not for flowhood but other filtering uses around the farm.

Mine lasted a year, not much compared to the 5 to 10 years they're given by lots of board members. Guess I should move the farm to the city, easier to sell mush as well. Where do you get the second hand filters. In France? We got more nuclear power here than in US

Frankly you should save a bit of money and buy a brand new one :

We've got filter manufacturer down here too !

I know, but more expensive then where I got them in Belgium. It's the insurance that makes it expensive. Tu es ou en France, you're a prof grower? Or just somebody who sells filters LOL

Somebody ever tried to clean an bad heap filter with air pressure. I guess you'll just blow hole in the the filter pleats. I ordered a new one, takes three weeks to get here. In the meantime I might as well try 'n clean the old one? huh?

Well, to keep you posted, I took out my HEPA and cleaned it with high pressure air on the intake side. Lots of dust coming out. Probably blew holes in it but you never know, might work. I'll fill some dishes this afternoon and we'll see what happens. I'm still waiting for the new filter I ordered.
