Intro: Activated Carbon Air FilterThis instructable shows you how to make an air purifier to filter pollutants such as tobacco smoke, pollen, solder fumes and many other organic materials out of the aithat you breathe.

Step 1:Needed materials and Basic IdeaComputer fanActivated CarbonGlueWindow screenpantyhoseModeler's plywood

Basswood or balsa12 volt AC/DC converter

If you have enough modeler's plywood, then you can make the frame out of that, but to save money, I chose to glue my frame together with some balsa wood I had. I everything but the activated carbon, which you can purchase at pet stores, already at my house.

The purifier works by drawing air through the carbon and forcing it out through the top. The picture below is a cutaway view. The carbon surrounds the purifier on fourwalls with the fan on the top. The large surface area allows the air to pass through slowly which cleans the air much better.

Image Notes

1. CA glue (aka super glue)2. 1/8 inch thick modeler's plywood3. Window screen4. balsa wood5. Activated Carbon6. 12 volt ac/dc converter7. Computer fan

Step 2:Make the FrameThis part is critical since it is what keeps your filter from falling apart, so cut and glue well. For the edges of the walls, I used 1/4x1/4 inch strip of balsa. To support themiddle, I used 1/8x1/4 inch strip of balsa. Next, make 4 of both the inside and outside walls. You may need to cut some small squares of paper to stick in the corners fextra support.

After the walls dry, lay the window screen out on wax paper. Apply a thin strip of glue to one side of each wall and place onto the window screen. The wax paper will kthe glue, which will run through the screen, from sticking to your table.

After the glue dries, cut each wall away from the sheet of window screen.

Next, cut a 45 degree angle in two sides of the wall so that the four outside and four inside walls can be joined to each other. Make sure that the window screen is on toutside of the square. In the end, you should have two squares with four walls covered and two left open (for the top and bottom of the filter).

Step 3:Putting it all togetherNow that you have the two frames made, you can put everything together. But before you do this, make sure you slide pantyhose over both frames. This will keep thesmaller bits of carbon from falling out.

Now, take the bottom part of the filter and glue the frames to it.

While that dries, clean the carbon. During shipping, small bits of dust will fall off. Clean it by placing it in a colander and running water through it. Let it dry and pour it in

the filter.

Next, once its full, glue the top on. NOTE: the small hole in the top is used for adding or removing activated carbon after the top is glued on. I just put tape over this tokeep the carbon from falling out

If all was done correctly, the fan should fit perfectly into the remaining hole in the top of the filter. Glue the fan in place and you now have a finished air filter.

Step 4:Finish it upThe white tube on the top of the filter is there to help spread the filtered air around the room. To make it, all you have to do it tape together a paper tube that will fit ovethe fan. The top is made by cutting vertical slits in the tube and overlapping them to make the paper fold over the top and deflect the air into the room.

To turn it on, you take the two computer fan leads and solder them to the 12 volt power supply. If everything works, it will be very hard to hear it running.

Lastly, if you want the filter to emit a fragrance into the room, it is very simple. Place your favorite liquid fragrance into a thin medicine bottle and tape it to the center offan. As the air from the fan passes the medicine bottle, it will pull the fragrance out of the bottle and into the air.

Now, the only problem with the filter is that the air emitted has a slight smell of carbon and I am not sure how to get rid of this. Since the fan cannot develop a lot ofpressure, forcing the air through another filter would be difficult. If you have ideas then feel free to email me.

csatchell says: Jun 29, 2009. 10:00 PM REPThis device is exactly what I am looking for, but one question: How do you attach the 12 volt AC/DC converter to the fan wires?

Crapxxas19 says: Feb 8, 2011. 1:11 PM REPcut the wire open and solder the + to the red and _ to the black. If you cant tell which is + and - guess and if the fan doesnt work, switch the wires.

Hatty says: Jun 30, 2009. 4:33 AM REPThere is just a positive and negative wire coming out of the fan and I hook that up to the positive and negative output of the power supply. Its as simplethat.

killprogram says: Sep 24, 2010. 3:52 AM REPah yes but be careful when doing so i would recomend getting all of your connections together and semi-permanently fastened BEFORE evenplugging it in and i mean i know it is dc but what if the transformer where to break just then? ill tell you what you would have a positivie and a negatend of AC power going from one hand through your chest and heart, to the other

Hatty says: Sep 24, 2010. 4:50 AM REP12 volts isn't really enough to break the skin and get into the body, so there really isn't much danger. But anytime you work with electricity youneed to take precautions.

Wally_Z says: Feb 1, 2011. 8:10 AM REPWell, you won't feel 12V. But if the amperage is high enough, it'll kill you if you let it arc across your heart.

Crapxxas19 says: Feb 8, 2011. 1:15 PM REP12v cant arc across your body. The resistance of skin is too much. In any normal case, when working with 12v and under it is impossibleto shock yourself unless you soak yourself in water for a few days.

Wally_Z says: Feb 10, 2011. 12:47 PM REPIf you actually READ what I wrote you will realize that I said "If the AMPERAGE is high enough, it'll kill you if you let it arc across youheart". Bad read^. AMPERAGE IS THE KEY WORD HERE. Google it if you don't know what that means.

Crapxxas19 says: Feb 10, 2011. 2:20 PM REPYou need voltage for amperage to kill!!!I have put my fingers across a 12v 5a source and i didnt feel anything. You need at least 40 volts with moist skin to even feelanything.

Crapxxas19 says: Feb 11, 2011. 1:53 PM REPThink of electricity like water. If you put your finger at the end of the faucet no water flows. This is like low voltage (pressure owater is low) and no amperage (there is no water coming out.) If you are using a hose, there is some water leakage becausethe pressure is higher so it means that amps are flowing. Basically you need some voltage to make amperage effectiveenough to kill.

GsE-Lance says: Mar 10, 2011. 3:47 PM REP30mA kills a person at 230v,Ampere = Volts/Resistance, in this case 12v / 1000r (resistance of the skin)Therefore Wally_Z's arguments are invalid.

Crapxxas19 says: Mar 11, 2011. 2:57 PM REPTHANK YOU!!!!!!!!!!!!!!!!!!!!!!!!!!Some people need to know what they are talking about, SERIOUSLY!!!!

WERNER SLABBERT says: Jun 10, 2010. 7:16 AM REPyou might actually try three fans in line. say for argument's sake the first fan gives you one bar of pressure, a second in line would double that to about 2.3bar of pressure and a third would then daouble that to about 4.6 bar. in theory that is.

XOIIO says: Jun 2, 2010. 7:31 PM REPCan you cut charcoal filters, or does all the charcoal stuff come out?

MrHyde says: Feb 25, 2009. 6:43 PM REPfor more pressure maybe use this http://www.instructables.com/id/Tesla-turbine-from-old-hard-drives-and-minimal-too/

chamunks says: Nov 27, 2009. 12:55 AM REPI'm curious how you would use this turbine to create pressure or apply the turbine to this. Maybe I'm just browsing instructables too late at night.

lemonshark10 says: Jan 21, 2010. 7:03 PM REPBy manually spinning the shaft of a tesla turbine th opposite effect is acheived and pressure is generated

junits15 says: Oct 15, 2008. 1:22 PM REPan extremely more affective way of making an air purifier is to buy a negative ion generator u can get them here simply put the part with the prongs on it ina continous screen that is wrapped around this. the negative ions attract any type of dirt in the air and cause it to stick to the screen. only downside is thatthe screen needs to be cleaned every now and then. the negatitave ion generator can also be use to charge a lyden jar! :D

chamunks says: Nov 27, 2009. 1:04 AM REPBroken Link.

junits15 says: Nov 27, 2009. 12:56 PM REPdamn i hate it when that happens!

chamunks says: Nov 27, 2009. 1:22 PM REPThank you I definitely appreciate the link fix I will certainly try to incorporate this into something.

Do you think this generator could be used in an ion fan build of some kind.

junits15 says: Nov 27, 2009. 7:49 PM REPim not sure if it would work as an ion fan, I 've never personally played much with these things (I have a certain fear of high voltages) and Idont know how powerfull one would have to be to generate an ionic wind, But I wish you good luck anyway!

chamunks says: Nov 27, 2009. 10:22 PM REPamperage is what you need to worry about as long as its not past .87 amps I believe its all good.

junits15 says: Nov 28, 2009. 10:57 AM REPyes but its still dangerous, especialy if you have a heart problem.

JusCoz says: Jul 16, 2007. 12:49 AM REPA simple HEPA filter works great, and is a lot cheaper. It also lends a certain interchangability. Cool instructable tho.

lemonie says: Jul 16, 2007. 6:49 PM REPActivated carbon has an affinity for organics, such as the non-prticulate components of smoke. This is less a particulate filter and more an odour / volatorganics filter. I doubt the effectiveness with pollen, but surely both HEPA and carbon could be used. L

chamunks says: Nov 27, 2009. 3:03 AM REPCertainly could use a hepa filter in this equation could always put a hepa fil ter Just below the fan inside the box this would also help prevent you're

fan from catching all the really tiny dust particles.

But Ideally if someone was concerned about really purifying the air the DIY method, one would use three filters.

Some reusable/washable filter Than a Charcoal filter for smell and finally a hepa certified filter for biotic and allergenic issues.

The reusable/washable filter would catch big dust and hair that can significantly shorten the l ifespan of you're Charcoal and Hepa filters.

The Charcoal filter was covered in the comments and article so Iwont bother but link you here. The carbon specifically used in this ible was from tlooks of it classified as GAC Granular Activated Charcoal.

Finally the HEPA Certified Filter will get rid of airborn pathogens and the rest of the superfine dust.

Hatty says: Jul 17, 2007. 9:56 AM REPThat is true. Activated carbon works on organic gases. The only reason I say it works on pollen is because every time my allergies start going crazystick my face in front of the fan on the filter and my problems go away. There is probably another explanation for this, but it works, so I use it.

Mitten says: Jul 15, 2007. 11:13 PM REPWould activated carbon really do anything for the air? It would seem like there would be a lot of gaps around the carbon.

monterto says: Jul 16, 2007. 4:33 PM REPthere are a lot of carbon filters out there. they are the most effective filters for the price. the activated carbon doesn't catch particles like a sive, it has ahigh surface area and a high absorption rate so as particles get sucked through the fil ter and brush passed the carbon they get sucked into the pores othe carbon. Brita water f ilters work the same way. this is why they need to be changed periodically also.

PacoBell says: Feb 12, 2008. 3:29 PM REPActually, don't activated carbon filters operate on the principle of a_d_sorption rather than a_b_sorption? They rely on their high surface area and thmaterial's surface energy. Wikipedia is your friend :)

chamunks says: Nov 27, 2009. 2:48 AM REPYou can also aquire a wide range of activated charcoal size grains so from what looks like gravel (used in this ible) to almost a fine powder. Ofcourse you will have to choose your screens accordingly and airflow can become lessened the finer the powder you choose.

Airflow, Purity, Efficiency,Its kind of a pick two scenario, you can have any of these two options but you sacrifice the third.

!Andrew_Modder! says: Aug 17, 2007. 5:01 PM REPcant you make carbon??? i saw in a science book you add something to sulfic acid and carbon is made :-\?

punkhead58 says: Nov 5, 2009. 7:59 AM REPUm...you can make carbon ash(charcoal) by burning wood, but in this case you need activated charcoal.

ci857s7 says: Mar 27, 2008. 11:29 AM REPI dont think you can make carbon, unless you do some nuclear fission or fusion of lighter or heavier atomic nuclei. Carbon is an element.

!Andrew_Modder! says: Mar 27, 2008. 1:20 PM REPoh i remember, if you put sugar into a thing of sulfuric acid, you can make carbon! thats all :-)

Win7Maniac says: Sep 28, 2009. 4:28 PM REPActually, the carbon is already there; the chemical reaction just separates it and takes it out of the sugar. However, you'd end up with a big, blacblob of metal. . . Not much you can or would want to do with that.

Shadowfury says: Feb 27, 2009. 3:01 PM REPOr you could just burn some wood...

Redgerr says: Jul 20, 2009. 8:48 AM REPthat was qutie funny

amddude says: Jun 13, 2009. 2:18 PM REPlol

Geekmandude says: Jan 17, 2010. 7:02 PM REPYou can activate normal carbon, I have done it. You just heat it. you can also reactivate spent activated carbon the same way, it drives othe impurities it has collected.

nckballer says: Oct 3, 2009. 12:04 AM REPI also forgot to say attach your fan box to the mailing tube

nckballer says: Oct 2, 2009. 11:59 PM REPFor adding another filter instead of using paper to construct a tube just use a 3"x36" Mailing tube you can find it at packaging stores(They are about $5) for

this size but get the size you need keep in consideration that I just had the tube laying around, if I were to of bought i t, it would be a lot shorter because I judont need that much! Now back to what I was saying you can attach the tube to your carbon filter box right above the fan(attach it anyway you likeglue,tape,whatever)make sure you dont have the tube too big and in the middle of the tube cut it in half this is where you will use some pantyhose andchicken wire to make your carbon filter and at the very take a l ittle cardboard box(or make one) and cut a hole for the fan and mount it on the inside oroutside of it and there you go you should now have decent enough pressure to get the air flowing. write me back and tell me what you think!

gilbert2048 says: Aug 23, 2008. 7:32 PM REPthis could be good for a solder venting system

Win7Maniac says: Sep 28, 2009. 4:29 PM REPHey. . . GREAT IDEA!!! I've been wanting something like that for a long time, I can't believe I didn't think of that!

Hatty says: Dec 31, 2008. 2:48 PM REPIt actually does work as a solder venting system. The only problem is that it doesn't suck in air at a high enough velocity to make it effective. Even thouit does suck solder fumes in and filter them very well, most of the fumes just go straight to my nose. If I wanted to make one, I would probably only havone side of carbon, use a converging nozzle into the fan, and only use a .25" thick wall of carbon. This would allow for a much greater airflow and,hopefully, pull the fumes away from my face. But, since I don't solder much, I think I can do without it.

Chowmix12 says: Jun 10, 2010. 5:15 AM REP

Instead of 4 inlet vents try limiting it to 1 so that the air pressure is not 'diluted' and you will have greater suction towards four soldering station... Analso, the fumes going to your face are harmless, after going through the filter...

Andrew Heine says: Mar 3, 2009. 11:22 PM REPincrease venting CFMs (cubic feet per minute, flow rate) by making a grid of four fans to draw the air. or whatever amount is necessary. the airvelocity through the filter should be 200 feet per minute, and big enough to catch all the fumes. quick calculation

gilbert2048 says: Jan 11, 2009. 7:10 PM REPthank you for that, and yes i would use a funnel as well
