I have been struggling for 3 weeks to get sediment out of my pool. I attach this bag to my pool vacuum and it sucked the sediment right out. There are small filament fibers floating in the pool now, but the skimmer will pick that up. This thing is exactly what I needed. Thank you. ### ⭐⭐⭐⭐⭐ Good product. *by R***N on Reviewed in the United States on May 3, 2018* Good product. I use this to filter my home brewed wine in order to remove the yeast so that I don't get a secondary fermentation. ### ⭐⭐⭐⭐ Very useful *by F***L on Reviewed in the United States on October 22, 2018* I am new at making wine, but this was easy to use and a good size --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/60013763-polyester-filter-socks-1-micron-rated-aquariums-coy-ponds-pools](https://www.desertcart.hr/products/60013763-polyester-filter-socks-1-micron-rated-aquariums-coy-ponds-pools) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-22*
