Cheap Hepa Filtration
    #19166106 - 11/20/13 03:50 PM (10 years, 2 months ago)

Just found this at salvation army used, and the filters
are pretty dirty -


Think I should go back tomorrow and pick it up? What use could I make out of it.

If you seen it, would you pick it up?

Im just looking for ideas for the clean air, it has five speed settings as well, and options for carbon/hepa filter or a
combination of both.

BTW. Retails for 80-110 $USD, Its there for $15 and I always talk em
down 5 bucks on stuff. Theoretically I could probably get it for ten.

Ignore this idiot.  If you can buy the purifier for $5 and just get replacement filters, you've got yourself a steal.  Real HEPA filtration usually runs $90 for a purifier, minimum.  And real to-standard HEPA is what you want for this hobby, instead of any imitation tech.

Make sure if you buy it, when you get the filters, they are True HEPA filters and not HEPA-type filters in the same size.  HEPA-type filters are capable of filtration down to .3 microns, but it doesnt have be be uniform across the enitrety of the filter, like it does with any filter that claims the HEPA scientific standard. 

Run it 24/7 in your grow room, perferably close to doorways and open air ducts for maximum filtration of new air entering the room.

If you feel like its a good deal, buy it. I have a hepa "like" filter running in my grow room 24/7. Its not a true hepa, but its better than nothing.

Yeah.  I have a furnace filter taped to the back of a box fan.
I figure it's better than nothing.

You'd be surprised at how much crap is in the air.

Hey keep us informed on the dehydrator I've been looking for one myself for a while now and maybe some people toss them by season so I might be able to go pick one up around the time you find one.

In both of these instances, I wouldnt run them prior to inoculation.  Moving Semi-Sanitized air is probably about equal with still dirty air.  Still Semi-santized air is best in this situation  Anything short of true-HEPA filtration is sketchy.  Many are only rated to 3 micron filtration, and there is no scientific standard to which it must adhere to.  Trichoderma harzianum, for example is as small as 2.5 microns. 
HEPA filtration is rated to filter, at minimum, 99.97% of all substances in the air bigger than .3 microns.  There are no varieties of Trichoderma smaller than 1 micron.
At the very least, make a flowhood using a True HEPA filter.

Thats good.  I just wouldnt recommend innoculating/G2G outside of still air in any case but True HEPA-Filtered air.  Don't want Trich circulated by your air purifier.

I am 99% sure i used to have that exact model that i would run in my room for allergies.  If I remember correctly it uses two filters side by side.  I can only speak for the one i had, the seal was basically crap around the filters and after running it for a while there was dust on both sides of the machine, before ans after the filter.  It was evident that the seal was bad because dust collected in and around both sides of the rubber indicating airflow.

I threw mine away...

Dust in a room with an air purifier is common, including in and on the purifier itself.  This is because almost all home air purifiers include an ionizer option.  Ionized air clings to surfaces easier and more often than natural air.  As to if it wasnt filtrating properly, I cant comment.  However dust is common on air filtration units even on the part that blows out, for that reason.

As amateur home mycoloigist I feel that anything we can do to keep our grow area (and the air in them) cleaner is definitely a good thing

I gave up on hepa filters and air scrubbers long ago. On paper, they sound great. In practice, they don't really help much. 

Work on your sterile technique instead :wink:

Oh, I've had no contams as of yet -

I was just going to use it as a source of clean, fresh air in a mini
martha I was working on...


:shrugs:

I know colonized myc is contam RESISTANT, but not invulnerable,

plus it would help keep mold from building up over the weeks inbetween cleaning,

right?

You're trying to put the hepa filter in the martha?

Don't bother.

Like I said, in theory, "air purifiers" look good. In practice, they are pretty much useless.

And you don't want to put your hepa filter in an extremely moist environment either.

And if you have mold building up on the actual martha, you have a serious issue with your fruiting conditions.
