Each Berkey system consists of an upper and lower chamber that houses the gravity driven purification process. The source water is poured into the upper chamber and the purified safe water collects in the lower chamber where it can be dispensed through a spigot.
CHOOSE YOUR SYSTEM
Berkey offers six different sizes of stainless steel units and one Berkey Light system constructed of non-BPA co-polyester. When choosing a system, it’s helpful to consider the following:
- How many people (includes pets) will be consuming (drinking,cooking,washing,etc…) the water.
||Dia (inch or cm)
||Storage Capacity (inch or cm)
||14 / 35.5
||4 / 10
||18 / 45.7
||7.5 / 19
||1 – 2
||21 / 53
||9 / 22.9
||2 – 3
||19.25 / 48.9
||8.5 / 21.6
||2 – 3
||23 / 58.4
||49.5 / 24
||2 – 4
||26 / 66
||10 / 25.4
||3 – 5
||30 / 76.2
||11 / 28
- It is worth noting that the price difference between models is relatively minor considering the significant difference in the storage capacities between them. After experiencing the benefits of purified Berkey water a significant number of clients reported they’d wished they’d chosen a larger model upon discovering their true demand.
- It is common for people to select a model size with a vision of where it will fit on their kitchen counter. For most of the Berkey models their assembled height makes it impractical to store it under kitchen cupboards. Several clients (including ourselves) have come to the conclusion that it didn’t make sense to occupy their premium kitchen counter space and chose instead to locate it outside the kitchen. This freed them up from any imagined space restrictions and resulted in a notable reduction in second guessing the chosen model size. The larger the system, the less often it will need to be filled.
CHOOSE THE NUMBER OF PRIMARY FILTERS (Black)
All of the Berkey models come standard with two Black Berkey purification filters and offer from 2 to 8 filter ports. The stated flow rates are determined under laboratory conditions with the upper chamber full to the top. As it is impractical in real life to keep the upper chamber completely full at all times, the flow rates are in practice less than the stated optimal rate.The more water in the upper chamber the greater the “head pressure” when determines the flow rate. The maximum flow rate happens when the upper chamber is full and it then decreases as the water level declines. For example, we’ve found that a Royal Berkey with 4 black and 4 white filters will produce about 1.5 gallons in the first hour (as compared to the stated “up to 8 gallons per hour”). In the case of a Royal Berkey w/ 2 black + 2 white filters, the flow rate would then be ¾ gallons in the first hour. (slightly more w/o the white filters in this measurement).
What does all this mean? Judicious filling and storage. The black filters construction (proprietary coconut shell based carbon combined with anti-viral, fungal, bacterial, inflammatory qualities of silver) lends itself to storing water. Utilizing a reserve storage vessel (ceramic, glass or non-bpa plastic) makes it less likely that you’ll ‘run out of Berkey water’ when you need it most.
There are 3 advantages of adding 2 more filters (in addition to the 2 supplied with each system):
1. Doubles the overall filter service life
2. Doubles the flow rate
3. Decreases the filter maintenance interval
(Please note that the purification quality of the water is the same regardless of the # of filters incorporated.)
Black filters offer a service life expectancy of 11,340 litres (3000 gals) each. Each basic Berkey system (with the exception of the GO Berkey which only comes with 1 Black Berkey) comes with 2 black filters bringing the total service life to 22,680 litres (6000 gals).
CHOOSE YOUR POST FILTERS (White)
The PF-2™ filters reduce the artificial fluoride, arsenic and heavy metals and are used in conjunction with the Black Berkey™ purification filters. Every drop of water goes through a black filter first and then the PF-2 filter attached to the threads of the black filters. The addition of the PF-2 filters will reduce the overall flow rate of your Berkey by 10 -15 %.
PF-2 fluoride/arsenic filters offer a service life expectancy of 1,890 liters (500 gallons) each. As the PF-2 filters need to be replaced more often than the black filters, you may wish to purchase additional sets at original system purchase. The PF-2’s come 2 / pkg
If your municipal water is artificially (HFSA) fluoridated (or has unsafe levels of naturally occurring fluoride / arsenic and/or heavy metals) then these are an important consideration. If none of these are a concern it isn’t necessary to include the PF-2’s in your purchase.
CHOOSE YOUR OPTIONS
Spigots. Each Berkey system comes with a standard plastic spigot.This is adequate for dispensing water but doesn’t allow you to see how much water is in the lower chamber. It’s worth mentioning that surplus water in the lower chamber will leak out once the water rises to where the upper and lower chambers meet. The optional sight glass spigot provides a visual confirmation of the water level in the lower chamber. Without the sight glass this can only be achieved by lifting the upper chamber (c/w filters and water – it’s heavy) off the lower chamber. For this reason, the sight glass spigots are popular. The sight glass spigot itself is still plastic and comes equipped with a stainless steel support tube housing a clear glass tube. We are regularly asked if there is such a thing as a 100% stainless sight glass spigot and unfortunately, these don’t exist. For those clients wishing to eliminate plastic from their systems, the stainless steel regular (non-sight glass) spigot is a popular option. (click here: )
Black Berkey Primer. The Berkey primer is a popular and cost effective tool that allows you to both prime and purge the black filters and offers three advantages:
- 20 % + better flow (over the brown priming washer)
- Allows the user to drive 90 % of the water out of the black filters. This is ideal when transporting or putting your Berkey into storage.
- The Primer allows the user to perform the priming/purging function without the need of water pressure. This is ideal when camping or in an emergency/disaster situation where other source water is being utilized.
Every Berkey system purchase comes standard with a brown primer button that is used to prime/flush the black filters. While‘functional’ this is a poor substitute for the primer given its advantages. (Click here for a video)
Shungite Type I stones. These are a great investment given Shungites’amazing properties.
We encourage you to take a closer look at Shungite here (click here)
Mineral Stones. These bump both the water PH + a host of minerals:
Calcium,Iron, Magnesium,Potassium, Zinc
Clients regularly report they prefer the taste of mineralized water as well. (Clients with all types of source water report that the mineral stones offer a welcome taste difference)
Shower and Bath Filters. We like to promote shower filters that offer replacement filters. The Santevia filter offers a 4 – 6 month service life while the Sprite filter offers a 12 month 25,000 gallon service life. Both brands offer replacement cartridges. Client feedback has been positive with both.(click here)
Hidden Benefit.The value of Berkeys’ portability isn’t on everyone’s radar. Some choose a system with the intention of also using it for their camping and traveling purposes. But perhaps one of the biggest hidden benefits is that a Berkey, which operates with no mechanical or electrical hookup, addresses the # 1 need should an emergency or disaster situation arise: Potable water. When the usual source water isn’t available, this is where you’ll most appreciate your investment in a Berkey as they will provide Safe water in almost any circumstance. For the same reason that some people keep their car gas tank ½ full or carry a spare jerry can, having a well maintained Berkey should be a priority for anyone that owns one. This reliability is the reason we named our company Safe Water Canada Ltd.
