It is quite abut larger then some of the other filter bag I’ve looked at. I am using these to remove impurities from home made tinctures, wines and as a rain water catchment filter. I have tested how well it worked by checking the product after filtering it with a microscope and am glad to report that it works just a good as it should. There is darn near nothing on the slide larger then a micron. ### ⭐⭐⭐ 3.0 out of 5 stars Bigger is usually better but may not work for my needs *by K***. on Reviewed in the United States on June 22, 2018* i havent used this yet. it arrived on time. It seems way bigger than described but i will go back and check that. Bigger is usually better but may not work for my needs. I will update review after I used to filter my homemade wine. I am hoping to push it up to 5 stars (If it gets all the yeast out). ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Product is as stated *by A***E on Reviewed in the United States on December 27, 2018* Product is exactly what it states --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/37159867-polyester-felt-filter-bag-1-micron-rated-aquariums-coy-ponds](https://www.desertcart.co.th/products/37159867-polyester-felt-filter-bag-1-micron-rated-aquariums-coy-ponds) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-30*
