How long do the filters last?

The two included Foundation filters are rated for up to 12 months. Buying the four-filter option extends coverage to about 24 months.

Does it need electricity or plumbing?

No. It is gravity-fed and sits on the counter. The only powered part is the Automatic Filter Primer, which primes filters in about 90 seconds.

It is certified to NSF/ANSI 42, 401 and 372 and removes over 80 contaminants, including lead, PFAS and chlorine.

How much water does it hold?

The system holds 3 gallons across its upper and lower chambers, enough for a household's daily drinking and cooking water.

Is it better than a Berkey?

Owners who switched say the stainless steel build and included primer compare well with Berkey systems. Both are gravity-fed carbon filters; BOROUX includes two filters and a lifetime warranty on the steel chambers.

Lid, upper chamber, lower chamber, base ring, two hole plugs and two Foundation filters (four with the larger filter option). A stand is not included.
