Never heard of, nor been charged an "env fee" for purchase of any filter, in the States ever. As already noted by another Canada resident in second post, must be a north of the border deal in some areas. Some places that change oil here add a disposal/env fee, but should/would be known about up front.
Also not sure how it works up that way, but many/most of the stores here are independently owned/franchised, meaning some leeway on sales and pricing. Example, I get my Napa Golds for less than $4 now on a their NG 40% off semiannual sale. Not a national sale, but a local sale making NG a terrific value imo.
Guess only way to tell for sure if that specific Napa store was 'trying to rip you off' is to visit a few other stores to see if same deal applies there. But based on second comment, wouldn't appear so.
All that said, solution simple, don't like it, shop elsewhere and buy something else.
