Cheap And Easy Bucket Hepa
|Posted by: Fungusmaximus May 17 03, 12:45 PM GMT|
| 1st you will need a 5 gal bucket
2nd an automotive air filter they range from 3$ to 15$ at wally werld.
This one Im using is the more expensive one, but a quick box switcharoo and someone only pays the 3$ minimum
3rd a circular fan no bigger than the bucket lid.
The more power the better, cheapo fans arent strong enough to pull air through the filter. "Vornado" brand is the best
4th a microparticle tack colth. Find em in the paint dept.
use this as a prefilter( not shown )
5th Great stuff foam sealant

|Posted by: Fungusmaximus May 17 03, 12:48 PM GMT|
| seal it up with the foam
|Posted by: Fungusmaximus May 17 03, 12:49 PM GMT|

| So total cost....
foam sealant 4$
but its way bigger than any hepa unit you can buy for 30$ and replacement filters are cheap as hell!

|Any idea how well it works, percentage wise. Could you attach a plastic bag on the filter and have a makeshift flow hood, or does it only work as a whole room filter? Either way, great idea FM!|
|Posted by: Fungusmaximus May 17 03, 01:35 PM GMT|
|gloveboxes, grow rooms, whatever it all really depends on how much you spend on the fan. spend 30$-50$ on a "vornado" and you have a flowhood/large room hepa|

|Has this been tested? I have been having a problem w/ contams on innoculation, so if this is a way to get myself a cheap flowhood that would be great. Do u think w/ this contraption set up as a hood , that it could keep a sterile agar plate sterile in it's flow?|

| Well I cant say all that...
But if you arent pulling air through the filter at the maximum force the filter can handle I dont think that the nasties that we are fighting are allowed through. At a higher cfm you may have problems. If you look at a hepa and look at one of these there is no difference in how they are made. Im not sure what the actual material is made of but it looks identical to the 30$ hepa filters at wallys. I checked while I was there. the box claims it removes contaminants from the air.... I guess I should give it the fool proof agar test.... At any rate it is at least the second best to a true hepa unit.
And will suffice for most of our needs.

| From the makers of the filter
FRAM® Comfortaire™ Passenger Compartment Air Filters
New from FRAM, Comfortaire Passenger Compartment Air filters. Finally, an air filter that was designed not only for the benefit of your vehicle, but for the driver and passengers inside. Fram Comfortaire Passenger Compartment Air Filters help remove contaminants that may enter your vehicle's ventilation system such as, pollens, exhaust gases from other vehicles, bacteria, dust and more. The FRAM difference is in the media - it's specially formulated media holds charcoal to help control odors.
Cabin Air Filters have been added as original equipment on late model vehicles, such as the Ford Taurus, Contour, Windstar and Ford trucks; the Chevrolet Impala, Monte Carlo, Suburban, Tahoe and Silverado; and the Lincoln Navigator. They are also common on popular Japanese vehicles, such as the Honda Accord and Odyssey, and the Acura RL and TL. Cabin Air Filter should be changed every 15,000 miles or by owners manual recommendation.

|I thought somthing with the power of squrell cage blower was mandatory to create a working flow hood.|

|so there is no HEPA filter on this thing, just an automotive filter? how do you know how clean the air is thats coming out?|
|Posted by: steveoi812 May 17 03, 05:45 PM GMT|
|Great idea maximus! I have been looking into buying some type of air filter for my foafs grow space to. I might have to give this one a shot...man you got a experimental mind bro...|

| so it's an automotive filter?
What makes it a HEPA bucket?
Seems to me it would make a great growroom filter,
but flowhood/glovebox filter?......I'm not convinced......yet.

| FM, correct me if I'm wrong:
HEPA is a filter standard... True HEPA filters will filter particles down to .03 microns; I highly doubt that filter works nearly as good as a True HEPA filter, as a real HEPA that size would cost upwards of $30 to $40.
I'm sure it works good FM, HEPAs are not necessary to have a clean growing environment, but they sure do kick ass!

|I used to use a cardboard box with a plastic window and rubber gloves taped around the hole. I'd spray the inside down and wipe with lysol spray. Place all the things to be used inside, seal it up and wait an hour or so to let all dust inside settle. Then go to work. Never had contamination.|

| Did nobody read the manufacturers statements I posted??
I got that from the fram website FYI
|Posted by: Fungusmaximus May 18 03, 06:36 PM GMT|
| I forgot to mention the that the microparticle tack cloth from 3m that should be your prefilter combined with this poorman's hepa filter is enough for me.
And as many of you know I was once the king of oddball molds. My house is a damn global mold spawning location.... Our basement floods and doesnt have adequate drainage, not to mention I have bales of straw strung out across the floor that is now soaked from rain water YIKES!
Stuffs been there so long it has sprouted green grass (or straw rather)
thats nearly knee high

Sounds like prefect Black mold country Be careful there Buddy

It may help remove some of that stuff from the air, but that is only an advertisment, that is not a guarantee that 99.99% of those particulated will be removed from the air flow. If it is anywhere near as effective as a HEPA filter, it would have the certification a HEPA does, the efficiency rating, ya know? HEPA is the key word. If the word isn't there, theres particles in the air.......
Most simple filters, even plain furnace filters, will have the same type of advertisement on the label, but is by no means a HEPA filter.

| Settle down guys ..... although Im not 100% sure, I think you all may be wrong. I sold cars for about 2 years and when I did of course we had to know about the cabin filters. Now that was a few years ago and I can remember which, but I do know that they filter down to either .7 or .3 microns I cant remember which, what is the the diameter of human hair ... does anyone know ?? Im thinking its 1 micron and I know for a fact they do better than that .... like I say, either .7 or .3 one of the two, which isnt to damn bad for a grow room filter that is to be ran 24/7 where you are not using one now, why not ?? It can only help keep your air clean in your room and is cheap as hell.
Bravo yet again FM !!

|BTW although we all know its not going to be as good as a hepa, my whole point is I bet its pretty close, remember, its a cabin filter, not a engine air filter. These cabin filters are designed to increase comfort by filtering the air that is allowed into the cabin, the filter must remove pollen and allergins to be effective and they do work. Soooooo like I say, I dont think its a bad idea FM has, its cheap, does a good job (although not as good as a true Hepa) and replacement parts would be a breeze to find and purchase|
|Posted by: trinity May 19 03, 09:41 AM GMT|
| yeah anything lower than 1.0 microns would be good, so if thats what it filters down to for sure, then i'd think its good for a growspace. nobody said how efficient it was, so thats what i was questioning.(plus the fact that someone was saying flowhood stuff with this kind of filter?) thanks ozz. this would be cheaper than a couple small hepas, for a nice size grow space.
