Filters and lifespan

How long will my filters last?
Black Berkey filter elements last 6,000 gallons per pair (3,000 gallons per element). For a typical household, that works out to a pair every 3 to 5 years. Phoenix Gravity New Millennium Edition Elements, the current replacement option, last 5,500 gallons per pair, on a very similar 3 to 5 year replacement window. How long your specific filters last depends on daily usage volume, source water quality, and how consistently you maintain the elements. Shop element sets.
How do I know when to replace them?
Not by the gallon count alone. The elements do not stop at that number, the flow tapers. Clean them when it slows, and when cleaning no longer brings it back they are done.
How do I run a red dye test?
Take the PF-2s out, add about ten drops of red food colouring per gallon of upper chamber and let it filter. Clear water below means the elements are sealed, pink means re-seat them and tighten the wing nuts. Step-by-step walkthrough.
Phoenix elements vs PF-2 filters?
Two different jobs on the same stem. Phoenix is the main carbon element, certified and rated 2,750 gallons, and does the taste and heavy metal work. PF-2 is the fluoride and arsenic post-filter that hangs below it, rated 1,000 gallons. PF-2 details.
Where are the filters made?
By a New Millennium Concepts partner in India that holds ISO 9001 and the WQA Gold Seal, with in-house carbon testing on every batch. Phoenix filter FAQ.

Using the system

How should I store the system and the filters?
Dry the canister completely. Used elements get shaken out, air-dried somewhere sunny for one to three days, then bagged so the carbon does not pick up odours. Scrub and re-prime before they go back in. Storage tips.
How do I set up my Berkey?
Prime first, always: an unprimed element drips or does nothing at all. Seat both elements with their washers, hand-tighten the wing nuts, fill, and throw away the first one or two batches. Open the quick start guide.
Can I use softened water?
No. A softener adds mineral salts the carbon cannot take out, and they clog the pores early. Draw from a bypass tap or an unsoftened line instead.

Water, sizing and testing

What do the filters remove, and what do the labs show?
Certified to NSF/ANSI 42 for chlorine, taste and odour, and 372 for lead-free materials, with lab data on 16 heavy metals by ICP-MS and PFAS below the reporting limit through 1,500 litres. See the test results.
What size Berkey should I get?
Capacity decides it, not water quality. Every stainless system runs the same elements, so a Travel Berkey makes the same water as a Crown. Pick by household size and how often you will refill. Size guide.
Can I use rain water or pool water?
Rain, yes, with a first-flush diverter and a sediment pre-filter, because roof runoff arrives dirty. Pool water, no: chlorine and pool chemicals sit far outside what a gravity element is built to handle and will exhaust the media.
Do the filters remove microplastics?
They retain particles at the micron scale, which is where microplastics sit, so the barrier catches most of what reaches it. We do not have a certified removal percentage, so we do not quote one. Test results.
How should I read a TDS meter?
Expect roughly your tap reading, and that is the point. The meter counts every dissolved solid, including the calcium and magnesium these elements deliberately leave in, and it cannot tell those apart from lead. What a TDS meter can and cannot tell you.
