What color should the desiccant cartridge indicate in order for it to be replace?
The color the indicator needs to be depends on what it was when the desiccant was fresh. If the indicator color was blue, then it will turn pink when saturated with moisture. If the indicator was orange, then it will turn green as it absorbs moisture. So, the desiccant cartridge will need to be replaced if the indicator is either pink or green. FYI: The desiccant indicators that turn blue to pink contain cobalt chloride, which is toxic. The orange to green alternative is non-toxic. Source: http:www.silicagelpackets.com
