99.999999% of bacteria
99.999% of parasites
99.999% of microplastics, silt, sand, and cloudiness
Watch:
THE 9s MATTER: In microbiological water treatment, it’s all about the number of nines after the decimal - which are generally referred to as log standards.
Testing performance for log thresholds is the ultimate measure microbiological filtration performance.
This is more important than comparing pore size.
There tends to be lower percentage standards for heavy metals and chemicals because it takes higher concentrations of these contaminants to cause illness. However, low dose concentrations of microbes can still make you sick, so you need the extra 9s.
The NSF recommends log 6 bacteria removal (99.9999%) and greater than log 3 Protozoa removal (99.9%).
If you are considering Virus removal, they recommend at least log 4 (99.99%). - see 3 below
When in the great outdoors: YOUR MOST IMMEDIATE CONCERNS ARE MICROBIOLOGICAL.
These can be broken down into three categories.
-
PROTOZOA/PARASITES –
The CDC (Center For Disease Control USA) lists Cryptosporidium and Giardia intestinalis as the top two most concerning protozoa or parasites to be aware of in backcountry water.
They result from runoff of animal and human fecal waste.
Cryptosporidium infection, or “Crypto,” in particular is very common – there are almost 750,000 cases a year in the USA.
What is most critical about Cryptosporidium is that iodine treatment and in many cases, chlorine treatment are not effective at killing Cryptosporidium (Chlorine-dioxide takes up to 4 hours).

-
BACTERIA – Campylobacter, Salmonella, Shigella, and E. Coli can all be found in backcountry waters.
These also result from animal or human fecal waste and can cause serious illness.
-
VIRUS - Rotavirus and noroviruses, Hepatitis A&E can be spread through water.
Human viruses come exclusively from infected human feces, so they tend to be less of a concern in the backcountry.
However, if you are in a location with a large amount of human activity, you may want to consider a different technology that protects against viruses – such as ultrafiltration technology or microfiltration with chemical treatment.
This product does not protect against HEAVY METALS, CHEMICALS, PESTICIDES, AND "OTHER STUFF"
This is what LifeStraw say:
"Beyond the microbiological umbrella, there may be heavy metals, chemicals, pesticides, and other unwanted substances in backcountry water.
These mainly become concerns if you are close to human activity or downstream agricultural or industrial activities.
These contaminants often need higher concentrations and longer exposure to cause illness.
In general, that makes this category of contaminant less of a concern for the backcountry and for short term exposures.
So, if you’re hiking for a few days, not a big deal.
BUT, if you drink from the same pond or use the same tap every day, that’s a separate issue that merits unique treatment technologies, in which chemicals and heavy metals should be prioritized to avoid prolonged exposures"
