Received DA2900003F compliant models instead of the reference DA2900003G, possibility of refund but not having the right reference in Kamp-Filter Company ("longer manufactured, replaced by another reference dixit society ...). Never had answered for the comment made, ie, removing the 3G reference their site to avoid, at least, mislead the customer. A priori, the model F 3 is less efficient (at the filtered pollutants), and cheaper than 3G. A reference to the proposed sale must be available, or not systematically removed and replaced by another, is to me a blatant lack of ethics ...
