Review on 🧦 Premium 4-Pack - High-Performance 200 Micron Replacement Filter Sock for Innovative Marine Fusion Desktop by Donald Shah

I'm a bit disappointed with this product. Unlike the original equipment, it is a kind of fluffy felt material. Everything is fine with the filter action, they are put in the aquarium normally (Nuvo 20), but they cannot be washed. I usually put my socks in the washing machine for a quick wash without detergent and they come out like new. Instead, these socks were frayed and bunched up, and one even had large holes in the fabric. You get what you pay for, treat them as disposable or hand wash only. If you want something that can be washed, buy the original.
