Every system here is the same BB9-2 pair in a different tank.

So the lineup is a tank menu: 4.5 gallons, 3.25, 2.25 and 1.5, and the money steps with it. The band runs *em*, and there's nothing different about the water on the way up. - Elements: one model across the line, rated 6,000 gallons a pair. - Tanks: 4 sizes, and every record publishes its own, so it's the only column nobody leaves blank. - The claims: 250+ on one record, 200+ on two more, and no figure on the fourth. - The zeros: there's no listing number, no replacement element price, and 1 flow rate across 4 records. **strong** you're choosing a vessel and living with one cartridge, and the cartridge is the half the listing won't price. The [full index](/best-water-filters) scores every brand this way. Think of it this way **strong** New Millennium Concepts sells 4 sizes of lamp and *em*, so the price step buys the shade. What the 4 Records Publish Bars showing what the 4 records carry: 4 tank sizes, 4 element ratings, 1 named certifier, 1 flow rate and no listing numbers.

Seven lines, 1 point each, and there's no partial credit. It leads on 3 numbers: a 6,000 gallon element rating, the middle tank and the cheapest running cost here. The 3 lines it misses are the standard, the document and the flow.

The most documented body still prints nothing a third party can check. Compare the Imperial Berkey 4.5 Gallon ## Berkey Water Filters: Who the Line Fits This line fits 1 to 4 people, a counter with a free corner, and a household that wants water during an outage. Tank size sets the rhythm: a 1.5 gallon body wants a fill twice a day, and a 4.5 gallon body gets a family through a workday. Pressure and plumbing have nothing to do with it. If your counter's too narrow for a tank, the countertop roundup prices the same no-install idea across 7 records, and the pitcher roundup starts at a jug that fits a fridge door. #### This Is Not Your Berkey If You want water on demand. Every system here makes a batch, and none of them makes a stream. - You're after a fast pour. The quickest body in the line runs 2.75 gallons an hour, about 6 ounces a minute, or a 10 cup pitcher in 14 minutes. - You want a certificate to hand over. One record names a certifier and none prints a number. - You need the box in California or Iowa. 2 of the 4 records say they won't ship there. The short version A Berkey is a coffee urn that filters. Nothing about it is plumbed, so *em*.

Twice a day at the small tank. [See the Travel Berkey 1.5 Gallon](https://www.amazon.com/dp/B00FMUYU6I?tag=waterfilternerd-20&linkCode=ogi&th=1&psc=1) ## What Berkey Water Filters Cost to Run **strong** Bands below, because prices move. - The Big Berkey: $367 once, 6,000 gallons on one element set, and about 6 cents for a gallon. - The Imperial: $526 for the same 6,000 gallons, about 9 cents each, plus 2 PF-2 elements rated at 1,000 gallons. - The Travel: $327 for the same element, which makes the small tank the cheapest way in. - The replacement pair: no price on any of the 4 records, so the second 6,000 gallons has none. *em* A Berkey gallon costs 6 times what a main line system charges, and the gap buys the absence of a plumber. The [whole house roundup](/best-whole-house-filters) treats one for about *em*, and it wants a shutoff and a wall. Contaminants Claimed for the Same BB9-2 Element Bars showing the contaminant counts the maker's copy claims for the same element: 250 on the Imperial, 200 on the Royal and the Travel, and no figure on the Big Berkey.

That's the whole line, and the rival row is what the rest of the class will charge you. The countertop roundup covers the gravity class this line lives in, and the Brita brand page covers the other end of the shelf. Put another way A big number with no document under it is a rumor with good manners. The 250+ here is the seller's own arithmetic, and there's no listing number to check it against. See the ProOne Big+ Rival Price The one outside body that names a standard number, at a lower band than any Berkey here. ## Berkey Water Filters FAQ Do Berkey water filters remove lead The element is claimed at 200+ or 250+ contaminants depending on which listing you read, and there's no listing number on any record here. Lead removal rests on the brand's own wording rather than a document you can key in. How much do Berkey water filters cost to run About 6 cents per gallon over the first cartridge. The replacement element price is on none of the records, so the second 6,000 gallons has no figure. How often do Berkey elements need changing The pair runs 6,000 gallons in every system, and the PF-2 elements the Imperial ships with are rated 1,000, so the two parts retire on different clocks. Do Berkey water filters work without electricity Yes. Gravity feeds the element and nothing's plumbed, which is why the line keeps turning up in the off grid conversation. Why do Berkey listings carry no certification number Because none of the 4 records prints one. A single record names a certifier, and the copy describes third party lab testing instead, which isn't the same as a listing. ## Berkey Water Filters Review: Where the Line Lands The pick is the Big Berkey: 6,000 gallons behind one element pair, a 2.25 gallon tank and about 6 cents for a gallon. The certificate, the listing and the rated flow are what hold it at 4. For the most water in the room, the Imperial adds 2.25 gallons for about 3 more cents a gallon. For the cheapest way in, the Travel carries the same element and rating, and the countertop roundup prices the rest of the shelf. One element, 4 tanks, 3 different contaminant counts and not a single listing number. Check the Price on the Big Berkey ### The Element Is the Constant and the Tank Is the Choice Every Berkey here carries the same 6,000 gallon pair, so the honest question is tank size, not filtration. The number that would settle the rest is a listing number, and there's none on any of the 4. See the Imperial Berkey 4.5 Gallon ## Every Term Berkey Water Filters Name Black Berkey BB9-2 The brand's own gravity element, sold in every system here and rated 6,000 gallons a pair. A media blend rather than a ceramic candle. PF-2 element The fluoride and arsenic add on that ships with the Imperial, fitted under the BB9-2 and rated 1,000 gallons, a sixth of the element above it. NSF/ANSI 53 The health effects standard, certified per listing, and it covers lead. No record in this line names it. Rated capacity The gallons one element is documented to treat: 6,000 a pair here, and it's the figure that turns a system price into a running cost. Listing number The keyable ID a certification record carries. 4 records, and none of them printed one. ## Keep Reading: More Berkey Water Filters Best Water Filters: the hub above this page. - Best Countertop Water Filters: the gravity class this line sits in. - Brita Water Filters Review: the other end of the shelf, priced per cartridge. - The Nerd Stamp Methodology: what each of the 7 lines asks for.
