The filter housing is made of chlorine-treated polypropylene, which is both durable and resistant to corrosion. Its sleek design allows it to blend well with any kitchen decor, making it a stylish addition to your home water filtration system.

The Kohler K-21372 Aquifer Refine CTO Carbon Block Filter is easy to install and can be used with most standard kitchen faucets. It comes with all necessary components for installation, including filter housing, filter cartridge, and O-rings.

Overall, the Kohler K-21372 Aquifer Refine CTO Carbon Block Filter is an excellent choice for those looking for a high-performance, easy-to-use, and stylish water filtration system for their home.
