The Neo-Pure NP-1SG filter cartridge is a sub-micron filter with electrokinetic attraction to reduce harmful heavy metals like lead and mercury, as well as microorganisms like giardia and cryptosporidium for 6 to 12 months. The NP-1SG Seagull Compatible Replacement Cartridges has a high flow rate with built-in flow restrictor to ensure proper contact time with the coconut shell carbon block media. The green caps are thermally bonded to the filter instead of glued for superior construction.

Features:Consumer Alert: The Neo-Pure NP-1SG now includes a built-in 0.75 gpm flow restrictor to ensure proper contact time with the media. The Original Seagull® RS-1SG(CA) filter cartridge has been independently tested with the Seagull® IV X-1 System at the WQA laboratories and found to have a flow rate of 1.32 gpm. The original cartridge claims optimal contaminant reduction at 1 gpm, yet flows 25% faster! Without an adequate flow restrictor, you may be unknowingly exposing yourself and your family to harmful contaminants.
To maximize the efficency of your filter cartridge with your Seagull IV X-1 system, install the Neo-Pure NP-1SG Compatible Replacement Cartridge which includes a built-in 0.75 gpm flow restrictor.
