On this page
The tap is dry after a storm, the stream at the campsite looks clear, and the choice comes down to berkey vs sawyer squeeze. A Berkey gravity system suits a household or a base camp that filters water in volume, while a Sawyer squeeze filter suits a hiker or a traveler who carries water in a pouch. The listings here tell a narrower story: only the Sawyer Micro Squeeze is a complete filter; the rest are replacement elements, a primer pump and replacement pouches. This comparison uses those listings to show what each side actually does.

Gravity against squeeze
Berkey and Sawyer Squeeze work in opposite ways. A Berkey system is gravity-fed: water sits in an upper chamber, passes through filter elements, and collects in a lower chamber. The PF-2 elements in this comparison attach to the bottom of Black Berkey Elements and sit in the lower chamber, where they adsorb fluoride, arsenic and other heavy metal ions. A Sawyer Squeeze system is hand-powered: water goes into a squeezable pouch, and hand pressure pushes it through a small inline filter. The Micro Squeeze is a 0.1 micron absolute inline filter that fits in the palm of a hand, and the SP113 pouches are the squeezable containers that feed it. Gravity suits a fixed spot where water can sit and drip through; squeeze suits a trail where the filter rides in a pack and works at a stream.
What each product filters
Each side filters different things, and the pouches and the primer filter nothing at all. The Micro Squeeze removes 100% of bacteria, 99.9999% of protozoa and 100% of microplastics through its 0.1 micron absolute filter. The PF-2 elements adsorb fluoride, arsenic and other heavy metal ions, but only when used with Black Berkey Elements, which do the main filtering in a Berkey system. The SP113 pouches hold water and attach to a Sawyer filter; they do not filter anything on their own. The Black Berkey Primer primes Black Berkey Elements and backflushes them with air; it does not filter water either. So the removal figures belong to the Micro Squeeze and the PF-2.
Filter life and weight
Filter life is where the filter listings part ways. The PF-2 elements are replaced after 1,000 gallons of use, under normal conditions. The Micro Squeeze is rated up to 100,000 gallons. That gap reflects what each product does: the PF-2 is a consumable element replaced after 1,000 gallons of use, while the Micro Squeeze is a 0.1 micron filter that comes with a cleaning plunger and a cleaning coupling. Weight follows the same split. The Micro Squeeze weighs 2 ounces, the PF-2 set weighs 0.62 pounds, the pouch 3-pack weighs 0.2 pounds, and the Primer weighs 0.02 pounds. So the numbers to compare are filter life and removal figures, not weight alone.
What the listings leave unclear
The PF-2, the Primer and the SP113 are parts, not complete filters. The PF-2 is a set of replacement elements for a Berkey system, the Primer is a priming pump for Black Berkey Elements, and the SP113 is a set of replacement pouches for Sawyer filters. Only the Micro Squeeze is a complete filter system on its own. Warranty terms are thin: only the PF-2 states a term, 6 months manufacturer, while the Micro Squeeze warranty description gives a gallon figure, and the pouches and the Primer state no term. No listing here states a flow rate, so filtering speed cannot be compared from these listings.

Berkey Black Primer
A hand-powered priming pump that primes Black Berkey Elements without a pressurized faucet or hose connection.
Pros
- Primes Black Berkey Elements without a pressurized faucet or hose
- Purges and backflushes Black Berkey Elements with air to clear debris
- Hand-powered priming works almost anywhere
- Light at 0.02 pounds
Cons
- Works only with Black Berkey Elements

Detailed Review
The listing states a hand-powered priming pump that primes Black Berkey Elements almost anywhere without a pressurized faucet or hose connection. Priming saturates the filters with water before use, removing pockets of air that can slow the filters. The Primer can also purge and backflush Black Berkey Elements with air, clearing debris from the filter wall. It is for use only with Black Berkey Elements.
Who it's for: Berkey owners who need to prime new Black Berkey Elements away from a pressurized faucet. Who should skip it: anyone without Black Berkey Elements, since it works only with them.

Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For water filters, safety means stated removal figures or another safety-relevant feature the listing names; the Micro Squeeze and the PF-2 state removal figures, and the pouches and the Primer do not. Only the PF-2 states a warranty term, 6 months manufacturer. The Micro Squeeze leads on performance as the only complete filter here, with stated removal figures and a 100,000-gallon figure. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Sawyer Micro Squeeze | 9.7 | 32 | 21 | 21 | 8 | 0 |
| Berkey PF-2 Elements | 9.4 | 23 | 20 | 19 | 5 | 1 |
| Sawyer SP113 Pouches 3-Pack | 9.2 | 18 | 19 | 19 | 0 | 0 |
| Berkey Black Primer | 9.2 | 15 | 18 | 16 | 0 | 0 |
Scores start at 9.2 for the lowest totals and top out at 9.8. In between, a kit’s position follows its weighted points one to one in order.
Berkey vs Sawyer Squeeze: which should you choose?
Choose a Berkey gravity system if you filter water at home or at a base camp and you own a Berkey system with Black Berkey Elements; the PF-2 elements add fluoride and arsenic reduction to it. Choose a Sawyer squeeze filter if you carry water on a trail or while traveling and you want a light filter that works at a stream; the Micro Squeeze is the only complete filter in this group, and the SP113 pouches are the spares that feed it. The Primer suits Berkey owners who prime new elements away from a pressurized faucet. Match the filter to the water you drink most often, not to the brand name on the box.
| If you need | Look at |
|---|---|
| Water for a household or base camp | Berkey gravity system with Black Berkey Elements |
| A light filter for a trail | Sawyer Micro Squeeze, 2 ounces |
| Fluoride and arsenic reduction | Berkey PF-2 Elements, 1,000 gallons |
| Spare pouches for a Sawyer filter | Sawyer SP113 Pouches 3-Pack, 32 ounces each |
Sizing Notes
- Match the PF-2 elements to a Berkey system that uses Black Berkey Elements, since the PF-2 attaches to the bottom of those elements and sits in the lower chamber.
- Match the pouch to the filter: the SP113 pouches fit the Sawyer MINI, Squeeze, Micro Squeeze and Dual Threaded MINI.
- Match the filter life to your use: the PF-2 elements are replaced after 1,000 gallons, and the Micro Squeeze is rated up to 100,000 gallons.
- Match the pouch size to the carry: each SP113 pouch holds 32 ounces, and the Micro Squeeze includes a 32-ounce pouch.
FAQ: power away from the grid
Can the Berkey PF-2 elements filter water on their own?
No. The PF-2 elements attach to the bottom of Black Berkey Elements and sit in the lower chamber of a Berkey system, so they need those elements to work. They adsorb fluoride, arsenic and other heavy metal ions when used with Black Berkey Elements.
How long does the Sawyer Micro Squeeze last?
The maker rates it up to 100,000 gallons, and it includes a cleaning coupling and a cleaning plunger.
Do the Sawyer pouches fit any Sawyer filter?
They fit the Sawyer MINI, Squeeze, Micro Squeeze and Dual Threaded MINI. Each pouch holds 32 ounces.
Is the Micro Squeeze the only complete filter here?
Yes. The PF-2 is a set of replacement elements, the Primer is a priming pump, and the SP113 is a set of replacement pouches.
Do any of these state a warranty term?
Only the PF-2, with a 6-month manufacturer warranty. The Micro Squeeze warranty description gives a gallon figure, not a term, and the pouches and the Primer state no term.
