No, if you read they say on the instructions they are only good for 500ml. I've used hundreds of them and sometimes you're lucky to get 1000ml depending on the carrier. I love them, they are just kind of expensive, but not really if you're making at least 500ml of a compound. I read where someone supposedly filtered 3L (3000ml). No way in hell. Also I've had two bad things happen. I buy them in cases of ten, sometimes you get a bad one and it just doesn't work, now that p***** you off and is out of your hands, then there are dirty Raws, you can get all the good out of the powder, but expect to use 2-3 filters. They are great when everything is good, but any problems and say goodbye to a few bucks and filters. A small secret that many people use is filter your stuff through 3 coffee filters all at once and it will get much or sometimes all the bad s*** out of your Raws. This is the way many people use to filter period. Good luck. The
