The single biggest reason to consider this cartridge pack is the combination of pleated polyester media with carbon impregnation, which delivers high dirt loading and extended service life in a 20in x 4.5in Big Blue format while fitting standard 20in heavy duty housings.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCombined filtration:\u003c\/strong\u003e Sediment filtration and carbon taste and odor reduction are provided in one cartridge to simplify maintenance and improve water flavor.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePleated design:\u003c\/strong\u003e The pleated polyester media offers additional surface area for high dirt loading capacity while keeping pressure drop minimal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-cellulose construction:\u003c\/strong\u003e Carbon impregnated non-cellulose media makes the cartridge suitable for both municipal and non-chlorinated water applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide compatibility:\u003c\/strong\u003e Fits all standard 20in Big Blue housings or other 20in heavy duty housings as a direct 20in x 4.5in replacement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended service life:\u003c\/strong\u003e The combination of pleated polyester and carbon filtration produces a longer usable life compared with some non-pleated carbon cartridges.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe NCP-20BB is best for homeowners with whole house Big Blue systems, users on well water who need polish filtration after other treatments, and anyone who wants to reduce chlorine taste and odor without sacrificing sediment capacity.
