Should the front and back sides be distinguished during use?** A: Cobetter PTFE and Nylon membrane filters come with a support layer, while PES, PVDF, PP, and MCE membranes do not. The membrane packaging box includes instructions indicating that the feed side should face upward. **Q: Are Cobetter PP membrane filters hydrophilic or hydrophobic? Do they have a support layer?** A: Cobetter provides both hydrophilic PP and hydrophobic PP membrane filters. Hydrophilic PP membranes are available in three pore sizes: 0.22 μm, 0.45 μm, and 1.0 μm. PP membrane filters are made of pure PP material and do not have a support layer. **Q: Are Cobetter Nylon membranes made of 100% pure nylon material?** A: Cobetter Nylon membrane filters are not made of 100% pure nylon material. They consist of a nylon coating layered on a polyester support. **Q: Are Cobetter membranes uniform in thickness and pore Size distribution?** A: Cobetter membranes employ precision manufacturing processes and stringent QC to ensure uniform thickness and highly consistent pore size distribution. For specific technical parameters of each membrane, please contact Cobetter. --- ## 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.co.za/products/510952655-100-pieces-pack-ptfe-disc-membrane-filters-hydrophilic-47mm-diameter](https://www.desertcart.co.za/products/510952655-100-pieces-pack-ptfe-disc-membrane-filters-hydrophilic-47mm-diameter) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-04-23*
