Sawyer Squeeze vs Lifestraw Peak Solo: Best Ultralight Water Filter for Backpacking?

Water filtration: it might not be the sexiest gear topic, but if you’re heading into the backcountry, it’s absolutely essential (read about why a water filter is a must-have in this article). And when it comes to backpacking filters, two names often dominate the trail—Sawyer and LifeStraw.

But which is the better choice? Let’s break it down so you can choose the filter that’s right for you.

The Sawyer Foundation's Three Pillars
The Sawyer Foundation’s Three Pillars

1. Sustainability & Social Impact

Sawyer

Sawyer donates 90% of its profits to non-profits working to provide clean water access worldwide. They partner with community organizations to not only distribute filters, but also train people in their proper use to ensure long-term health and safety. Also important: one filter can last 10 years of daily use before it wears out, which means these filters create far less waste.

LifeStraw

LifeStraw is no slouch either. They’re a certified B-Corp and climate neutral company. Their Peak Series Solo filter is also made from 50% recycled plastic. For every 500 products sold, LifeStraw donates a community purifier to a school, providing water for 100 kids for five years.

Winner: Sawyer. While both companies go hard on global impact, Sawyer gets the point for making such long-lasting products that don’t need replaced every season or two.

2. Price Point

  • Sawyer Squeeze: $40
  • LifeStraw Peak Series Solo: $30

Winner: LifeStraw. It’s cheaper upfront. But wait…

3. Longevity

  • LifeStraw: 2,000 liters
  • Sawyer: 10+ years (of daily use, with proper care)

Winner: Sawyer. If you take care of it, the Sawyer can last a decade or more—making it the more sustainable, long-term option, and cheaper in the long run, too.

4. Weight & Size

  • Sawyer: 2.0 oz
  • LifeStraw: 1.7 oz

Winner: LifeStraw, but by a hair. Both are ultralight.

5. Filtration Power

Bacteria99.99999%99.999999%
Protozoa & Parasites99.9999%99.999%
Microplastics100%99.999%
Filter Pore Size0.1 micron (absolute)0.2 micron

Winner: Sawyer. Slightly better performance, especially on protozoa and parasites.

6. Ease of Use & Backflushing

LifeStraw

The Peak Series requires a special plunger for backflushing. It’s effective, but it’s another piece of gear to have to carry, which adds weight.

Sawyer

Includes a clever little backflush adapter that works with any standard water bottle. Lightweight and field-friendly.

Winner: Sawyer for its simpler, smarter design.

7. Flow Rate Test

With similar squeeze pressure and the same one liter of water:

  • LifeStraw: 18.56 seconds
  • Sawyer: 20.31 seconds

Winner: LifeStraw, but by just under two seconds. Not a deal-breaker.

Verdict: What’s the Best Backpacking Water Filter?

If you’re ultra-focused on weight or budget, the LifeStraw Peak Solo gets the job done. But for longevity, sustainability, smart design, and slightly better filtration, the Sawyer Squeeze comes out on top, making it our pick for most trips.

Both are fantastic filters from companies doing real good in the world. But if you’re planning more than a couple of trips—or want a filter that won’t end up in the landfill after one season—Sawyer’s the one to beat.
