The reverse osmosis membrane on the packaging says to flush the system for 48 hours. It is unwise to buy a company product and then run the faucet for 2 days before I can count on clean water. In addition, the English inscription on the packaging was under the Chinese. Also, the filters I ordered were generic and not the ones in the photo.
