Some very expensive commercial CA cabinets have been observed to have a department store room humidifier attached to the cabinet by means of a hose through which steam, and sizeable water droplets, are sprayed into the cabinet. As a timer, simply place a fingerprint on the die-cut circle attach to the adhesive strip prior to placing over the hole of fuming chamber. Fingerprints leave behind traces of amino acids, fatty acids, and proteins. The second fundamental principle of fingerprints is that a fingerprint is an individual characteristic (T/F). . Higher heat, within reason, will result in shorter fuming times and lower heat, conversely will result in longer fuming times. Personally I would select a 3M Combination Cartridge/P100 particulate filter of the correct recommendation (organic vapor and acid series). B.
