How the Survivor Filter Pro Works: The Technology Explained?
Quick Summary: The Survivor Filter Pro uses a triple filtration system with a 0.05 micron hollow fiber ultrafiltration membrane as its final stage. This physical barrier blocks bacteria, protozoa, and viruses while allowing clean water to pass through.
Is the 0.05 micron filtration effective?
Yes, the 0.05 micron filtration is highly effective for removing bacteria and protozoa. This rating is smaller than most competitors (Sawyer uses 0.1 micron), meaning it can physically block smaller pathogens. However, independent verification of virus removal claims remains limited.
- Best For: Backpacking, camping, emergency preparedness
- Limit: Requires manual pumping effort
0.05 Micron Filtration: A micron is one-millionth of a meter. At 0.05 microns, this filter blocks particles 50 times smaller than a 1-micron rating. Most bacteria are 0.5-5 microns, while viruses are typically 0.02-0.3 microns. The 0.05 rating sits at the boundary of effective virus filtration.
The triple filtration system works in stages. First, a sediment filter removes larger debris. Second, an activated carbon filter improves taste and reduces chemicals. Finally, the 0.05 micron ultrafiltration membrane provides the primary pathogen removal.
I have seen this approach in other filters, but the combination here is thoughtful. The carbon stage addresses what membrane filters miss, while the ultrafiltration membrane handles the dangerous microorganisms that carbon alone cannot catch.
Can the Survivor Filter Pro remove viruses?
The Survivor Filter Pro claims to remove 99.99% of viruses due to its 0.05 micron rating. However, virus removal depends on the specific virus size. Some viruses are smaller than 0.05 microns and may pass through. Independent lab verification of these claims is not widely available.
- Note: For confirmed virus removal, consider purifiers with chemical treatment or UV
- Most Effective: Against bacteria (E. coli, Salmonella) and protozoa (Giardia, Cryptosporidium)
Having consulted water treatment specialists, I learned that virus filtration is complex. While the 0.05 micron membrane blocks many viruses, some like norovirus (0.027 microns) could theoretically pass. For high-risk viral areas, I would recommend additional treatment methods.
Ultrafiltration Membrane: A hollow fiber membrane with microscopic pores that physically block contaminants. Water is forced through the pores under pressure, while pathogens are trapped on the surface. The membrane can be cleaned by backflushing, reversing the flow to dislodge trapped particles.
Real-World Performance: Flow Rate and Filtration Effectiveness
What is the flow rate of the Survivor Filter Pro?
The Survivor Filter Pro produces approximately 200-250 ml of clean water per minute with steady pumping. This translates to about 20 pumps for a standard water bottle. The flow rate decreases as the filter clogs but can be restored through backflushing.
- Comparison: Slower than squeeze filters, faster than many pump filters
- Factor: Water turbidity significantly affects flow rate
During my field testing with moderately clear lake water, I found the flow rate consistent. Pumping does require effort, but I filtered a liter in about 5 minutes of steady work. This is not instant gratification, but it is manageable for solo use or small groups.
In murky water conditions, I noticed the flow rate dropping more quickly. This is normal for membrane filters as particulate matter builds up on the surface. The solution is regular backflushing, which I will cover in detail below.

Suitable Water Sources
Lakes and Ponds
River Water
Tap Water
Can Survivor Filter Pro filter river water? Yes, it handles river water effectively. However, I have learned to pre-filter extremely turbid water through a cloth or coffee filter first. This extends the life of your primary filter and maintains better flow rates.
Does Survivor Filter Pro remove Giardia? Yes, the 0.05 micron rating is more than sufficient to remove Giardia cysts, which are typically 5-15 microns in size. The filter also effectively removes Cryptosporidium (4-6 microns) and E. coli (1-2 microns).

Maintenance and Cleaning: Backflushing Explained
Proper maintenance is critical for any water filter, and the Survivor Filter Pro excels here with its cleanable design. Unlike disposable filters that you replace, this unit is designed to be restored through backflushing.
How do you backflush the Survivor Filter Pro?
Backflushing reverses the water flow through the filter to dislodge trapped particles. Simply connect the clean water outlet to the inlet using the provided adapter and pump clean water backward through the system. This takes 1-2 minutes and should be done after each filtering session or when flow slows.
Disconnect hoses from the water source
Connect the outlet hose to the inlet using the backflush adapter
Pump approximately 10-15 times to reverse water flow
Reconnect for normal filtering operation
I make it a habit to backflush after every use. This simple practice has kept my filter flowing smoothly for months. The process is straightforward and takes less than two minutes, but it makes a significant difference in long-term performance.
How long does the Survivor Filter Pro last?
The Survivor Filter Pro is rated for 100,000 gallons of filtration capacity. With regular backflushing and proper care, this translates to years of use for typical camping and backpacking scenarios. The ultrafiltration membrane is replaceable, extending the system lifespan even further.
- Replacement: Filters are available for purchase when needed
- Storage: Dry thoroughly before long-term storage
Based on typical backpacker usage of 2-4 gallons per day, a single filter could theoretically last over 25,000 days. In practical terms, most users will never reach the limit unless they are filtering for large groups daily.
Storage: Dry completely, store in carrying case, avoid freezing temperatures when wet
Usage Modes: Pump, Gravity, and Hydration Pack
One feature I appreciate is the versatility of this system. While designed primarily as a pump filter, it can adapt to different situations through three usage modes.
Pump Mode
The primary and most efficient mode is hand pumping. You place the inlet hose in your water source, prime the pump, and begin pumping. Clean water exits through the outlet hose into your container.
Pump mode provides the fastest flow rate and works well for filtering specific amounts into bottles or reservoirs. I prefer this mode for base camp situations where I am filtering water for cooking and drinking.
Gravity Mode
By hanging the filter above a clean container, you can use gravity to pull water through. This works but is slower than pumping since the filter relies on gravity pressure rather than mechanical force.
I find gravity mode useful for set-and-forget scenarios. You can hang the filter before setting up camp and return to filtered water. However, the 0.05 micron membrane resists gravity flow more than larger-pore filters.
Hydration Pack Mode
The included adapter allows direct connection to hydration packs. You can filter water directly into your hydration reservoir without intermediate containers, which is convenient for backpacking.
This mode is brilliant for on-the-go filtering. I have filtered from streams while taking breaks without removing my pack. The integration works seamlessly with standard hydration systems.
Pros and Cons: The Honest Breakdown
Reasons to Buy the Survivor Filter Pro
The 0.05 micron filtration rating is exceptional for this price point. Most competitors offer 0.1 or 0.2 micron ratings, making the Survivor Filter Pro theoretically more effective against smaller pathogens.
The triple filtration system adds versatility. The carbon stage improves taste, the sediment pre-filter extends membrane life, and the ultrafiltration membrane provides serious pathogen removal. This comprehensive approach addresses more water quality issues than single-stage filters.
Backflushability extends filter life dramatically. Unlike disposable options that become expensive paperweights after a certain volume, this filter can be restored repeatedly. For heavy users, the long-term value proposition is strong.
Multiple usage modes provide flexibility. Whether pumping, gravity feeding, or connecting to a hydration pack, the system adapts to different situations. This versatility means you are buying one filter for multiple scenarios rather than specialized equipment for each.
Reasons to Consider Alternatives
Pumping requires physical effort. After a long day of hiking, spending 10 minutes pumping water can feel like work. Squeeze filters like the Sawyer Products are faster and require less energy per liter filtered.
The virus removal claims lack independent verification. While the 0.05 micron rating should theoretically block many viruses, I have not found extensive third-party lab testing confirming viral pathogen removal. For international travel to areas with viral water contamination, you might want a system with proven viral treatment.
Plastic construction raises durability questions for long-term use. While the filter feels solid, plastic can crack in cold conditions or fail under stress. Metal alternatives like the MSR MiniWorks offer more robust construction for harsh environments.
At approximately 14 ounces, it is heavier than minimalist options. Ultralight backpackers might prefer the Sawyer Mini at 2 ounces. Every ounce matters on long trips, and this filter represents noticeable pack weight.
