Geekpure 20-Inch Whole House Water Filter Replacement – Carbon Block Cartridge (4.5 X 20) For Clean Water

About This Product

This Geekpure replacement cartridge is a solid choice for anyone looking to keep their whole house water system running clean.
It's a standard 4.
5 x 20-inch carbon block filter that pulls out chlorine, bad tastes, odors, and fine particles that can mess with your water quality.
It works with most standard filter housings and is rated for up to 90 psi and temperatures between 40–110°F.

A little tip—make sure to lube the o-ring with silicone grease when installing so you don't get any leaks.
The filter typically lasts around 6 to 12 months or up to 100,000 gallons, depending on your water quality and usage.

It's a good idea to keep an eye on it and swap it out when the filter starts looking dark or brown.

This one pairs great with a sediment filter if you're running a two-stage system.

Whether you're filtering well water or just want better-tasting tap water, this cartridge helps protect your appliances and gives you fresher water from every tap in the house.
Affordable, easy to install, and genuinely effective.
