Vance,
Air volume, velocity, and resistance are the important factors. There's plenty of data on the web regarding the absorption capacity of various products (sofnolime, sodasorb, etc) which means for a given volume of the material you can easily calculate the duration of the chemical based upon the amount of CO2 being expelled. The harder parts are anticipating and dealing with the dynamics such as packing of the material, size of the material, and the absorption latency of the material. Sodasorb, sofnolime, etc comes in different mesh sizes and has to be "packed" into the housing. Too tight and you restrict air flow too much. Too loose and you allow air to escape that has not been cleaned. In terms of air velocity, you have to be careful not to have a fan that pushes the air too quickly or it won't spend enough time on the chemical (latency) to get cleaned. There are a lot of factors to consider which for a home built unit means testing to see how it performs. Specifics are important here, so when you find something that works let us know exactly how it was built, what kind of fan, airflow (cu ft/min), etc.
