Gravity Water Filter Systems

A gravity system asks nothing of your kitchen. No power, no plumbing, no water pressure — you pour water in the top, and it filters down through the elements into the chamber below. That's the whole mechanism, and it's why these systems keep working when the power doesn't.

Every system here is built from polished 304 stainless steel and runs on the same filtration media, so the only real decision is capacity. The 1.5 Gallon suits one or two people and takes up about the footprint of a coffee maker. The 2.25 Gallon is the everyday choice for a small family. The 3.25 Gallon is for larger households, or for anyone who wants reserve capacity on hand. The 5 Gallon Field system stacks and travels, for camping, missions and emergencies.

All of them remove up to 99% of common contaminants — lead, chlorine, VOCs, pesticides, PFAS, PFOS and microplastics among them — verified by independent lab testing. Elements are replaceable, so the system itself is a one-time purchase. Not sure which size? Our FAQ walks through household size and daily use.
