I’ll admit that the recognition of these large, chrome steel, gravity-fed water filters remained a thriller to me for some years—at the same time as multi-gallon water filter methods from manufacturers like British Berkefeld and Berkey appeared to proliferate equally amongst lovers of doomsday prepping and holistic wellness retreats.
I’ve been testing a lot totally different breeds of water filters for greater than a 12 months now, together with reverse osmosis filters and water pitchers. However typically, the large water filter tanks have appeared as very similar to standing symbols as practical objects. They’re handsome in an industrial stainless-steel type of manner: an expression of a way of life and a stately level of satisfaction. For those who see an enormous gravity-fed filter, you realize the particular person in query is critical about wellness, survival, or each.
What modified my thoughts about these massive chrome steel filters was microplastics. Most water filter pitchers are fabricated from BPA-free plastic. However as new analysis reveals that bottled-water drinkers ingest tens of hundreds of extra microplastic particles, wellness lovers have begun to look askance at water filters which can be themselves fabricated from plastic.

A more moderen technology of gravity filters has leaned into this, eradicating all—or almost all—factors of contact with plastic. And so I put a pair of those new-school filters to the check. The Boroux Legacy Water Filter System ($419) is a good-looking gravity-fed filter system from a former Berkey distributor whose livelihood was disrupted by Berkey’s combat with federal regulators (see beneath). The Rorra Countertop System ($549) is a newer-school, celebrity-endorsed filter from a trio of serial entrepreneurs, with sensible options that embrace sensors for each filter and water ranges.
In testing every, I assessed ease of setup, plastic content material, complete chlorine discount, and modifications to dissolved solids or pH. I additionally pored over every filter’s NSF/ANSI certifications and impartial testing outcomes.
Advantages and Detriments of Gravity-Fed Water Filter Methods
Gravity-fed water filter methods gained their largest prominence in the USA with a system known as the Berkey—whose makers started in 1998 as a distributor for a a lot older filter system known as the British Berkefeld. Amid authorized troubles for Berkey (see beneath), a more moderen technology of gravity-fed filters has risen to prominence.
Multi-gallon filters like this are imposing beasts—as a lot assertion items as water filters. They’re massive, holding a gallon or extra. They reside in your counter or your desk, and take up vital house there. However as a result of they’re so giant, they’re tough to fill and sluggish to filter. In my early testing, gravity-fed filters like the brand new Boroux and Rorra do not essentially filter water any higher out of the field than plastic pitchers that may slot in your fridge door, or in-line filters below your sink. And since they do not slot in your fridge, your water is room temp.
However comfort is relative. The jugs on gravity-fed filter methods are sufficiently big on an in a single day refill to supply a day’s price of water for many households, for sipping and cooking and low. I discover this may be simpler than the fixed cycle of filling and ready that plagues smaller water pitchers, particularly for giant households, espresso lovers, or avid cooks. And whereas most water pitchers require common filter re-ups, the Boroux filters promote that they want substitute solely yearly. (Extra on this declare later).
