Filtration Rate and Capacity
The UltraPress operates with impressive speed and consistency. Every 16.9 oz (500 ml) press typically takes around 10 seconds, equating to roughly 3 L per minute. The cartridge capacity is only rated for 300 presses (~150 L)—much less than squeeze-style filters, or the Katadyn BeFree, but still adequate for many trips.
Filtration Capability
What sets Grayl apart from other filtration systems is its purification ability, not just filtration. It eliminates 99.99% of viruses, 99.9999% of bacteria, and 99.9% of protozoa, meeting EPA standards—including pathogens like norovirus, Giardia, and hepatitis A. The activated carbon and ion-exchange elements also reduce heavy metals, PFAS chemicals, sediment, microplastics, flavors, and odors.
Weight and Packability
Weighing 12.5 oz (354 g) and standing about 9.75″ tall with a slim 3″ base, the UltraPress is bulkier than typical ultralight filters but fits well in pack side pockets and most cup holders, especially considering this is a complete filtration and drinking system so it would replace the water bottle you would otherwise pack with a squeeze system.
Ease of Use
Grayl UltraPress equires no setup—just fill the outer reservoir, insert the inner bottle, press down with body weight, and you have drinking water in seconds. As the cartridge ages, pressing may take more force, but the process still remains straightforward. Smart design elements like the SimpleVent cap and SoftPress pad make the operation smooth and comfortable.
Price
At around $90, the UltraPress is costlier than basic filters (e.g., Sawyer Squeeze) and BeFree. However, it’s priced appropriately for a high-performance purifier that removes viruses and chemicals which other filters cannot.
Quality and Materials
Grayl builds the UltraPress from BPA-free polypropylene, ABS plastic, silicone, and TPE with a rugged design able to survive 10-foot drops on concrete even while full. Every component is replaceable—including the inner bottle, outer shell, and cartridge. A 10-year shelf life on unused cartridges adds to its long-term value .
Consumer Sentiment – Pros & Cons
Pros:
- One-step purification that kills viruses and bacteria
- Fast flow—just 10 seconds per fill
- Robust construction with thoughtful features like non-slip press handles and one-way valves
- Modular & replaceable parts = long-term sustainability
Cons:
- Bottle is heavier and bulkier than squeeze or straw filters
- Needs considerable strength as cartridge ages
- Smaller 500 ml capacity means frequent refills; may not suffice for ultralight or long solo trips
- Drinking cap is not tethered, so it can be easily lost
How It Compares to Other Filters
Sawyer Squeeze / Platypus QuickDraw / LifeStraw Peak Series Solo: Grayl doesn’t just purify, it filters (including viruses). It’s heavier, more epensive, and less versatile but offers greater protection if thats needed.
Katadyn BeFree: Both products are very simple to use. While BeFree is cheaper and lighter than the UltaPress, the level of filtration and purification is much greater with the UltraPress.
Who Is This Intended For
The UltraPress is perfect for frequent global travelers, international backpackers, disaster-preppers, and anyone heading into areas with virus or chemical contamination. It suits day hikes, camping, and urban travel where water safety is uncertain. It’s less ideal for ultralight treks, long single-bottle trips, or cold-weather use where freezing is a concern.
