The 20-Inch Big Blue (BB) Block Carbon Filter Cartridge<\/b>\u00a0is the standard for heavy-duty water treatment in large residences and commercial properties. Unlike granular filters, the extruded carbon block design eliminates “channeling,” ensuring that every drop of water makes maximum contact with the carbon media for total purification.<\/p>\n Superior Chemical Adsorption:<\/b> Specifically optimized to neutralize harsh chlorine and chloramines commonly found in municipal water supplies. It provides a chemical-free experience for showering, cooking, and washing.<\/p>\n<\/li>\n Natural Coconut Shell Carbon:<\/b> Made from sustainably sourced coconut shell, which features a finer pore structure than coal-based carbon, making it more effective at trapping a broad spectrum of organic contaminants.<\/p>\n<\/li>\n Mechanical & Physical Filtration:<\/b> The solid block structure acts as a physical sieve to trap suspended particles and dirt while utilizing physical adsorption to attract and hold pollutants.<\/p>\n<\/li>\n No Carbon Fines:<\/b> The high-density bonded construction prevents the release of “carbon black” or fines into your water lines, which is a common issue with loose-fill filters.<\/p>\n<\/li>\n Protects Critical Equipment:<\/b> Acts as a vital pre-filter for large-scale Reverse Osmosis (RO) systems and UV sterilizers by preventing microorganisms and chemicals from fouling sensitive membranes and bulbs.<\/p>\n<\/li>\n Energy-Efficient & Passive:<\/b> Operates naturally via water pressure without the need for electricity or pumps, providing consistent performance even during power outages.<\/p>\n<\/li>\n<\/ul>\n Whole-House POE Systems:<\/b> Provides filtered, chlorine-free water to every faucet in a large villa or apartment complex.<\/p>\n<\/li>\n Commercial Pre-Filtration:<\/b> Essential for restaurants, cafes, and light industrial units requiring large volumes of high-quality water.<\/p>\n<\/li>\n Industrial RO Systems:<\/b> Used as the third stage of pretreatment in 250 LPH, 500 LPH, or larger RO plants.<\/p>\n<\/li>\n Aquariums & Fish Keeping:<\/b> Safely removes chlorine and organic compounds that are harmful to sensitive aquatic life.<\/p>\n<\/li>\n<\/ul>\n Upgrade your water quality with the 20-Inch Big Blue (BB) Block Carbon Filter Cartridge<\/strong>. Engineered from 100% premium coconut shell activated carbon, this high-capacity cartridge provides a massive surface area to adsorb chlorine, volatile organic compounds (VOCs), and foul tastes or odors. It is a universal fit for all 20″ jumbo housings, making it the ideal choice for large Sri Lankan households and commercial water systems.<\/p>\n Function:<\/b> Effectively reduces up to 99% of residual chlorine, sand, rust, and organic chemicals.<\/p>\n<\/li>\n Capacity:<\/b> Industrial-grade design treats up to 100,000 gallons<\/b> of water.<\/p>\n<\/li>\n Micron Rating:<\/b> 5 to 10 micron precision for simultaneous chemical and sediment filtration.<\/p>\n<\/li>\n Jumbo Size:<\/b> Large 4.5-inch diameter ensures high flow rates with minimal pressure drop.<\/p>\n<\/li>\n<\/ul>\n","protected":false},"featured_media":9077,"comment_status":"open","ping_status":"closed","template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"product_brand":[],"product_cat":[33,24],"product_tag":[],"class_list":["post-9076","product","type-product","status-publish","has-post-thumbnail","product_cat-water-filter-cartridges","product_cat-water-filters","desktop-align-center","tablet-align-center","mobile-align-center","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/product\/9076","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/comments?post=9076"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/media\/9077"}],"wp:attachment":[{"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/media?parent=9076"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/product_brand?post=9076"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/product_cat?post=9076"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/product_tag?post=9076"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Key Features & Benefits:<\/b><\/h3>\n
