Overview
The Pureline PL-400-S is a coconut carbon block replacement cartridge sold in a three-pack, sized at 2.32 x 2.32 x 8.03 inches for housings built around that cartridge format. It carries NSF 42 and NSF 372 certification plus IAPMO and WQA listings, and suits owners restocking an existing filter system.
Pureline does not publish a compatibility list with this batch, so the deciding factor is whether your current cartridge matches this exact size rather than the brand name on your housing. Coconut shell carbon block filters like this one target chlorine taste and odor and sediment rather than dissolved minerals or heavy metals, which the NSF 42 rating confirms while NSF 372 (lead-free construction) covers a separate claim.
- Coconut shell carbon block media
- 2.32 x 2.32 x 8.03 in cartridge size
- NSF 42 / NSF 372, IAPMO, WQA certified
- Three-pack
Who it's for
Fits households already running a cartridge-style filter, whether under-sink or fridge-mounted, that takes a 2.32 x 2.32 x 8.03 inch cartridge and just need certified replacements on a three-pack cadence. Not the product to start from if you do not yet know your housing's cartridge dimensions.
Pros and cons
- NSF 42 and NSF 372 certified
- Sold as a three-pack for fewer reorders
- Coconut carbon block targets chlorine taste and odor
- No compatibility list provided, sizing is the buyer's job
- No stated capacity or replacement interval
Performance notes
Coconut-based activated carbon block filtration works by adsorption, pulling chlorine, sediment, and taste and odor compounds out of water as it passes through the block. NSF 42 certification confirms that adsorption claim was independently tested, while NSF 372 confirms the cartridge itself is lead-free rather than saying anything about filtration performance.
