I Found This On the Inter Net Somewhere And thought ill Share It Here WIth yall



TO HELP YOU FIGURE WHAT SIZE FILTER AND FAN YOU NEED, HERE IS A SIMPLE WAY TO FIGURE IT OUT.

WIDTH X LENGTH X HEIGHT = CUBIC FEET

(TO BE EFFECTIVE-THE AIR IN THE ROOM SHOULD BE EXCHANGED AT LEAST ONCE EVERY 5 MINUTE)

CUBIC FEET / 5 MINUTES = CFM NEEDED

EXAMPLE:
8 X 8 X 8 = 512 CU FT


512 / 5 = 102 CFM NEEDED

ACTIVATED CARBON Research Studies and Facts

Activated carbon is non-toxic. Basically, bituminous coal is totally carbonized by being subjected to high temperature and then is exposed to high-pressure steam, which causes the carbon to fracture, with almost infinite microscopic fissures that retain passing molecules. There are so many of these pores that one pound has a surface area of 60 to 150 acres. This carbon is unwashed so that you can be assured it is virgin carbon and not recycled (regenerated) activated carbon.
Some carbons are activated or washed with phosphoric acid, zinc chloride, or potassium hydroxide. These chemically treated activated carbons could leach phosphate (an algae promoter), heavy metals, or alter pH.
This activated carbon is NOT acid-washed.

SOME CARBONS ARE POWDERIZED, HAVE ADDITIONAL TREATMENT AGENTS ADDED, AND ARE THEN EXTRUDED IN PELLETIZED FORM. THIS CARBON IS IN GRANULAR (i.e. crushed char which is then sieved by particle size) FORM AND HAS ABSOLUTELY NOTHING ADDED TO IT. THIS CARBON IS USED FOR VAPOR AND LIQUID PHASE. ACTIVATED CARBON AIR FILTERS
Activated carbon air filters are the most effective type of filter against chemicals, gases, cigarette smoke and other odors.

Activated carbon air filters trap odors and chemicals in highly adsorbent granules (or pores), which look like a hard scrub brush.

Activated Carbon is effective at removing the following types of chemicals:

Acetaldehyde Cyclohexanol Hydrogen fluoride Paint & redecorating odors Acetic Acid Cyclohexanol Hydrogen iodide Palmitic Acid Acetic anhydride Cyclohexene Hydrogen selenide Paradichlorbenzine Acetone Decane Hydrogen sulfide Pantane
Dibromoethane Incensen Pentanone Acrolem Dichlorobenzene Indole Pentylene Acrylic Acid Dichlorodifluoromethane Iodine Pentyne Acrylonitrile Dichloroethane Iodoform Perchloroethylene Alcoholic Beverages Dichloroethylene Irritants Perfumes, cosmetics Amines Dichloroethyl Isophorone Phenol Ammonia Dichloromonofluormethane Isoprene Phosgene Ameyl acetate Dichloronitroethane Isopropyl acetate Pitch Amyl alcohol Dichloroprpane Isopropyl alcohol Poison gases Amyl ether Dichlorotetrafluoroethane Isopropyl ether Pollen Aniline Diesel fumes Kerosene Poultry odors Asphalt fumes Diethylamine Kitchen odors Propane Automobile Exhaust Diethyl ketone Lactic acid Propionaldehyde Benzene Dimethylaniline Dimethylsulfate Propionic acid Body odors Dimethylsulfate Menthol Propyl acetate Borane Dioxane Mercaptans Propyl alcohol Bromine Diproyl ketone Methil acetate Propyl chloride Burned Flesh Ether Menthyl acrylate Propyl ether Burned Food Ethyl acetate Methyl alcohol< /TD > Propyl mercaptan Butadiene Ethyl acrylate Methyl bromide Methyl bromide Butane Ethyl alcohol Methyl butyl ketone Propylene Butanone Ethyl amine Methyl cellosolve Propyne Butyl acetate Ethyl benzene Methyl cellosolve acetate Putrefying substances Butyl alcohol Ethyl bromide Methyl chloride Putrescine Butyl cellosolve Ethyl chloride Methyl chloroform Pyridine Butyl chloride Ethyl ether Methyl ether Resins Butyl ether Ethyl formate Methyl ethyl ketone Rubber Butylene Ethyl mercaptan Methyl formate Sauerkraut Butyne Ethyl silicate Methyl isobutyl ketone Sewer odors Butyraldehyde Ethylene chlorhydrin Methyl mercaptan Skalote Butyric acid Ethylene dichloride Methylcyclohexane Slaughtering odors Camphor Ethylene oxide Methylcyclohexanol Smog Caprylic acid Essential oils Methylcyclohexaone Sour milks Carbolic acid Eucalyptole Methylene chloride Stoddard solvent Carbon disulfide Fertilizer Monochlorobenzene Styrene monomer Carbon dioxide Film processing odors Monofluorotri cloromethane Sulfur dioxide Carbon tetrachloride Fish odors Naphtha Sulfur trioxide Cellosolve Floral scents Naphthziene Sulfuric acid Cellosolve acetate Fluorotrichloromethane Nitric acid Tetrachloroethane Cheese Formaldehyde Nitro benzenes Tetrachloroethylene Chlorine Formic acid Nitroethane Tobacco smoke odor Chlorobenzene Gangrene Nitrogen dioxide Toilet odors Chlorobutadiene Garlic Nitroglycerine Toluene Chloroform Gasoline Nitromethane Toluidine Chloronitropropane Heptane Nitropropane Trichlorethylene Chloropicrin Heptylene Nitrotoluene Trichloroethane Citrus and other fruits Hexane Nonane Turpentine Cleaning compounds Hexylene Octalene Urea Coal smoke Hexyne Octane Uric acid Creosote Organic Chemicals Onions Valeric acid Cresol Hydrogen bromide Varnish fumes Valericaldehyde Crotonaldehyde Hydrogen chloride Ozone Xylene Cychlohexane Hydrogen cyanide Packing house odors


EDIT: I Found It Off This ebay seller http://cgi.ebay.com/6-X-14-ACTIVATED...3%3A1|294%3A50

nice find. thanks for sharing this little gem. respect!

I actually bought one of those filters for a 8x8x8 room and my room is bigger than that but the unit hangs overhead in the closet and its just aight nothing special maybe 3/5 stars for workability.. thereagain may be better with bigger filter but my closets like 40 cu feet lol. Just my rooms 12x12

Lol is That Right...


Cuz I Was gonna Purchase one Off Them but i then decided Ill just build My own.......... But Havcent Yet made My Mind Up 100%
