Review on 🧼 Pack of 12 LTWHOME Foam Filters for Eheim 2618080 Aquaball 2208-2212/60-180, Biopower 160-240, and Prefilter 4004320 by Ashley Coffman

Visually identical to the Eheim pre-filter sponges. Same height, width, hole size. It fits normally in the pre-filter, however they are noticeably softer. I don't know if it's a different material or just not as dense as the official one, but it creases very easily while those from the Eheim brand are pretty tough. Time will tell how well they hold up. I have two official sponges and one of those "unbranded" sponges in my pre-filter to test them out. Even if they don't last as long, they're *significantly* cheaper, so it might still be a better buy in the long run.
