Great for any application where constant flow allows this filter to do its job over several capacity cycles. It won't give you a true 1 Micron filtration on a single pass, but if the system is constantly circulating it will definitely pull out darn near everything bigger than that 1 Micron size over a few hours. It took out the nagging last bit of particulate in an infusion system we use for making flavored waters. But, again, it won't do a great job on a single pass, it needs to be in the flow for at least a few hours. We perc our solutions for 3-5 days to ensure complete infusion and this sock filter sits in the sump inside the enclosed processing cabinet and after a couple of days it is obviously doing a much better job than the floss and cheese cloth and poly mats we were using. After the 4th day it is nearly impossible to even lens any particulate.

Made my own pool filter bags with these. Worked perfectly.

Worked as expected

I was having a problem with small particles passing through my pool filter and was not able to get the cloudiness out of the water. I attached this filter to my return line and within 4 hours the filter was brown and the pool was looking exceptionally better.

Good but can be better price
