Superior Filtration Performance: This 20-inch water filter cartridge uses a three-stage filtration process that combines PP cotton, granular activated carbon, and a sintered carbon block to deliver exceptional water purification. The initial PP cotton layer effectively captures sediment, rust and other particulate matter down to 1 micron, extending the life of subsequent filters and improving overall water transparency. The granular activated carbon layer adsorbs chlorine, odors, and organic contaminants, improving the taste and smell of your water. Finally, the sintered carbon block further refines the water by removing any remaining impurities and providing an additional filtration layer. This multi-step approach ensures you get clean, fresh-tasting water for various applications, including drinking water, cooking, and appliance protection. Ideal for use in whole-house filtration systems, commercial water purifiers, and reverse osmosis systems. Wide Compatibility: Designed with versatility in mind, this 20-inch water filter cartridge is compatible with a wide range of water filtration systems, including whole-house filters, commercial water purifiers, and under-sink reverse osmosis systems. Its standard size ensures easy installation and replacement in most standard 20-inch filter housings. Whether you're looking to improve water quality in your home, office, or commercial facility, this filter cartridge offers a convenient and reliable solution. It is also compatible with pre-filter water purifiers, box-type water purifiers, reverse osmosis water purifiers under the sink, and multi-stage ultrafiltration water purifiers. Enjoy the flexibility of using a single filter cartridge in multiple systems, simplifying maintenance and reducing inventory costs. This filter cartridge is not compatible with Huawei, Samsung, APPLE or Garmin products. Cost-effective solution: Investing in this 20-inch water filter cartridge is
