My $3 Carbon Filter

dragongrower said:

Thanks Chemi...Your talking about the aquarium type pads, right? Should those be mounted on the inside of the box so the fan pulls air through the pad or mounted on the outside so the fan pushes the air through it? I've heard that there may be issues with the pc fan having enough power to pull/push through carbon filters...is that something that I should worry about with the carbon pads?

The location of the filter is up to you,if you mount the filter on the outside of the case there is a chance where stale air could be pushed around the sides of the filter & let smell escape,the same issue applies with mounting inside the case,if there are any areas around the sides of the filter where stale air can be sucked through it will once again smell up the joint.

The main thing to remember when using any type filter is this, pressurized air weather being pushed or pulled will ALLWAYS TAKE THE PATH OF LEAST RESISTANCE,no matter where the filter is mounted or what method is used to attach the filter the resistance principal dictates how to best use the filter.

As for the filter being too thick for the pc fan your going to need to do some experimenting to see,ya gotta remember as far as fans go you are using the smallest & weakest fan out of all fan types,it is what it is & you have a tiny little fan, any material you put inline with that small of fan is going to slow air flow,how much it slows the fan depends soley on the material used.

If it were me i'd use the guy's idea of fish tank filters,i'd go to meijers & buy every type & thickness filter they have,test them all,use the model that works best & return the rest.

Just want to say your bud dryer & Carbon filters are an awesome donation to the community. I like tha tyou test all your items out and do blind tests on your family with them. You are a true inspiration!

I'm thinking this may be a good thing to use on the inlet to extend the life of expensive filters?

I'm thinking the point is to replace the expensive filters, but yes you should make this with light amount of carbon to not affect airflow and save your more expensive filter.

Not trying to Dis your design. Just trying to improve by stating Vapour based charcoal works and Charcoal for water does Not.

Activated carbon is used in gas purification, gold purification, metal extraction, water purification, medicine, sewage treatment, air filters in gas masks and respirators, filters in compressed air and many other applications.

How long do these filters last for you and what size exhaust fan are you using? Sorry if you already answered this I just didn't feel like sifting through 30 pages lol.

Stop buyin your shit at wally world . killin the world

pretty slick, if you built a box to house the carbon filters it would be even better. a box just big enough to hold a few finished filters. then just use a blower adapter for the inlet and outlet of your carbon filter box. you could even put a hinge and latch on the box for easy opening. only thing is you might want to use some weather strip to make sure it seals nice and tight.

just a couple of these and a box and you are golden...

Hey man thats pretty cool to hear,thank you.

Bosco huh,is that like the drink bosco ?

I havent thought about bosco in decades,i thought it was a relic & stopped being sold.

How thick can you make it? I have a ceiling fan mounted outside my cab on the top and going to have a tray of carbon on the inside.

You can make it thick as your fans ability to push/pull air through it.

For what its worth a exposed tray of carbon is going to do very little or nothing at all about smell,chances are nothing at all.

I got the idea from the DIY here using a panasonic ceiling fan. Why don't you think it would work?

I know it wont work for 2 reaoson,one reason is my hands on experience with the smell from plants in full bud.

The other & main reason im sure it wont work is the method is unsound to start with,blowing air over something will not capture smell,the odor filled air will roll right over the medium.

First off you have to understand odors,what odors are & why we smell them,all odors are made up of matter,particles if you will,to stop the odor using filtration you must capture the particle causing the odor,this means FORCING the particle filled air through something that will absorb .

Blowing air over some type of medium does nothing to capture particles causing odors,many people have tried putting different filters on the front of a box fan & blowing room air through the filter & it never works & never will for one reason,air is like water in the fact that it will ALLWAYS take the path of the least resistance,no exceltions,air will simply blow around the filter or in cases like yours it will blow oved the filter medium.

Filter sysyems that are not sucking air THROUGH the filter will never work.

thnx for the info panhead. I am going to have air pulling through carbon. pretty much a tray filled with carbon and a exhaust fan over it sucking air through the carbon tray and out of my cab. idk if u can picture it now what i mean.

For carbon to truly work, you need air flowing through it... having air pushed across the surface will help some but a small percentage. You want the air being forced through a carbon filter.
My DIY Inline fan is perfect way push air or pull air through panheads $3 carbon filter... I recommend everyone to use panheads carbon filter especially now with my diy fan.

hey reverof. can u post pics of your diy inline fan?

I will tonight, gotta use the mrs's phone to take pics as mine went swimming LOL

(sorry for the unintended hijack panhead)

But I do push this diy carbon filter
