(GAC) filters) available on the market specify a 0.5 micron rating
There are a wide variety of granular activated carbon (GAC) filter systems available on the market, with various ratings in terms of micron size. In general, most GAC filters will have a rating of at least 0.5 microns, with some as low as 0.01 microns. The exact micron rating of a particular filter will vary depending on the manufacturer and filter model. The filter's micron rating should always be checked before purchasing to ensure the filter is capable of filtering out the desired particles.
Activated carbon is used in methane and hydrogen storage, air purification, capacitive deionization, supercapacitive swing adsorption, solvent recovery, decaffeination, gold purification, metal extraction, water purification, medicine, sewage treatment, air filters in respirators, filters in compressed air, teeth whitening, production of hydrogen chloride, edible electronics,and many other applications.
