According to Camco, they are both the same filter.

The Camco 40621 and 40624 filters are NOT THE SAME. What is the difference between the 40624 and the 40621? VOCs (Volatile Organic Compounds). The 40624 removes these where the 40621 does not. Examples of VOCs are benzene, ethylene glycol, formaldehyde, methylene chloride, tetrachloroethylene, toluene, xylene, and 1,3-butadiene. See the attached table for information put out by Camco. You will find the 40621 in the third column and the 40624 in the forth column.

This question was answered almost two years ago. It is possible at that time, there were no differences in the filters or we could have possibly received incorrect information from someone at Camco. The information you provided is great. Thank you so much for updating us with this information.

I did not contact Camco but I find the 40624 is described as removing VOCs (Volatile Organic Compounds) and the 40621 never has this description. Why would they be the same filter but not have the same description? Would it not be a benefit to Camco to describe the full ability of the 40621 if they are the same? Removing VOCs, such as benzene, ethylene glycol, formaldehyde, methylene chloride, tetrachloroethylene, toluene, xylene, and 1,3-butadiene, is very important to me.
