These are very sturdy and actually nicer than the “more expensive” ones sold at stores.

Great product

These filters work perfect for my aquarium no complaints! Good price!

I like these socks but I refuse to clean them. Always looking for a lower cost option but these are not bad.

I love my filter socks. They make my sump maintenance so much easier. I've read other reviews that said after washing them in a washing machine they fell apart or was ruined some how. I can tell you from my experience that they have held up very well after multiable machine washes. I have washed mine more times then I can count and they are still going strong. They do a good job of keeping my fish tank clear. They are easy to clean. I love them. I would buy them again.

These are excellent filter socks, and are made well with very good material. These are going to last me a very long time. The size was exactly what I needed. I don't think you can beat these for the price.

I've ordered these numerous times and what I received was individually wrapped socks that were of good quality. This time I received one ziploc bag with all 12 in there loose. They are fuzzy and after 3 days my sump had water coming out the top because they were all clogged up. I never had that problem with the other ones. I change them when they start looking dirty, but they never became clogged. Is there any chance of getting the same quality I received previously? If not, I will have to find an alternative.

Standard size sock opening, easy to clean.Remember if using stock filters they get cleaned every few days to work properly.
