Undersink water filter replacement

The Swift Green SGF-K201 is a direct replacement cartridge for Kohler K-201 undersink filtration systems. It fits the existing housing without tools and restores the original flow rate. The filter uses coconut-shell activated carbon to reduce volatile organic compounds, lead and MTBE. Certified to NSF/ANSI 42 by IAPMO, it delivers cleaner drinking water and ice.

Households needing certified undersink filtration

Suits owners of a Kohler K-201 system who want a USA-made filter with NSF 42 verification and eco-friendly construction. Not intended for whole-house or high-capacity commercial installations that require larger housings or higher flow rates. Buyers without a compatible undersink head should look at a complete system instead.

0.5 micron coconut-carbon cartridge

The half-micron pore structure traps sediment, rust, chlorine taste and odour while the coconut carbon provides 50 percent more micro-pores than traditional carbon sources. This single specification determines whether the filter meets the contaminant-reduction claims verified under NSF 42.

Questions about this item

Do I need an existing Kohler K-201 undersink housing to use this SGF-K201 filter?

Yes, the SGF-K201 is a replacement cartridge designed to fit inside a Kohler K-201 or compatible undersink filtration housing.

Will this .5 micron coconut carbon cartridge restrict flow on an older faucet or dispenser?

The filter is engineered for a fast flow rate and precision fit to prevent leaks, so it should not noticeably restrict flow on existing hardware.

How can I verify the filter is reducing VOCs and lead after installation?

The filter carries IAPMO certification to NSF/ANSI 42 for the verified contaminant reduction claims, confirming it performs as tested.
