Charcoal Fiber Filters - Any luck???

Hey RIU-ers,

I was looking around and found these. If anyone has used these "charcoal fiber" filters please vote on a scale of 1 to 5; 1 being that they removed no smell at anytime and 5 being that they removed all the smell, all the time. For hearsay and speculation please only post text (restrain from voting). Thanks everyone!

dude all you need to know is how the activated carbon works to understand that the stupid filters they sell wont work for more than a few hours to days at most.

Activated carbon works on the same premise as your lungs do. SURFACE AREA.

Like your lungs which if stretched out and flattened for the surface area that gas exchange takes place (I think its several tennis courts of area) Activated carbon is named so because of its surface area.

Its created by high temps and is asininely porous thereby giving you massive amounts of surface area to scrub organic molecules eg, scents into and trapped by the carbon.

Those silly ass filters that go on cars made with a bunch of carbon dust arent going to do much. They are for mild use on an occasionaly run filter for say kitchen smells or when you have the family over and they smoke cigarettes.

Dont wast your money, you can build your own filter for cheap and it will work.

Right, which is kinda why these had appeal to me. Every time I look at the typical activated carbon scrubber I think about all those little pellets in them. It makes me wonder how much of those pellets actually gets used. In my mind, for every pellet the only effective part is the surface, which constitutes very little of the pellet volume. This in effects adds a whole lot of unnecessary, and unused, weight to the filter.

These "fibers" are apparently like a giant flat sheet of activated carbon that has been corrugated and wrapped around a cone. The premise being that now the only part of the material being exposed is the surface; no more internal volume being wasted.

The question to me is: can they really make activated carbon into a fiber and then weave that into some sort of sheet like they've done here? You may be totally correct that this is just a marketing ploy and that these products have no merit whatsoever; which is why I wanted to see a vote from people who have personally used them.

I agree that the typical can-type filters work well. I have one in my closet that seems to do the trick. The reason why these appeal to me is mainly their weight, which I believe is around 2 pounds for the 4" model. This would be great because I could hook this up straight to the intake side of my air cooled hood without the need for extra tubing and bends, etc.

I can see why you would want them. I just know that there is no way any of them could compare in surface area to the pellet ones.

It would be nice to not have a 15 pounder sitting there doing the work if you could easily just use a lightweight filter.

I have no problems with the pelleted ones I use a big motha for when Im painting in the garage (auto stuff) and I dont want the neighbors complaining. I go thru mad pre filters though..........as I should Im putting contaminants in the air at wholesale.
