The rate is nearly the same as the discontinued Melita filter!Thank you!! ### ⭐⭐ maybe too sturdy? *by A***E on Reviewed in the United States on March 8, 2021* These papers are well-made and not floppy or crammed in a too-small box. They are NOT fast papers. My primary filtration went from about 30 minutes to over 2 hours (8 liters). I'd have to say these fall in the range of medium to slow, not fast ### ⭐⭐⭐⭐ Performance on par with expectation. *by A***R on Reviewed in the United States on June 14, 2021* Fit well the funnel --- ## 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.tw/products/401113020-11-cm-lab-filter-paper-standard-qualitative-grade-4-zenpore](https://www.desertcart.tw/products/401113020-11-cm-lab-filter-paper-standard-qualitative-grade-4-zenpore) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-10-24*
