Berkey Water Filter (Big Berkey)

Water Purification

Gravity-fed, purifies up to 6,000 gallons, home base essential

The Big Berkey is a countertop gravity filter: two stainless steel chambers, filter elements in the top, filtered water collecting in the bottom with a spigot. No power and no plumbing.

Key specs (from Berkey)

Who it is for

Households of about one to four people (Berkey's own guidance) who want a no-power countertop filter they can use every day and lean on during outages or boil water notices.

Who should pick something else

If you need something to carry, it is bulky. If you want a system with a published third-party virus-reduction certification, check the specific element version and its test documents before you buy, and see our gravity filter head-to-head for an ultrafilter option.

How it fits a prep plan

A countertop gravity filter turns stored or collected water into drinking water without power. Pair it with stored water first, then keep it as the way to stretch that supply.

A simple order works for most homes: store water first (the common guideline is one gallon per person per day), keep a filter or purifier to stretch that supply, and keep a disinfection method such as unscented bleach or drops as a backup. Each layer covers a gap in the others.
