It depends on what micron size you're using. The tighter the sock the more stuff it will trap and get clogged quicker. I used to use 25 micron ones which lasted about 24 hours. I had about 5 socks that I used in rotation. Now I am using the 50 micron ones from Ocean Aquatics and they last about 7 days or so before they start to overflow which is fine with me
