From the Sawyer website FAQs regarding their purification systems.
Sawyer’s filters and purifiers are rated in Absolute Microns. This means there is no pore size larger than 0.1 or 0.02 micron in size on the PointONE™ and PointZEROTWO™ respectively. This means that it is impossible for harmful bacteria, protozoa, or cysts like E. coli, Giradia, Vibrio cholerae and Salmonella typhi (which cause Cholera and Typhoid) to pass through the Sawyer filters and purifiers. At 7 log (99.99999%) the filter attains the highest level of filtration available today. The PointZEROTWO™ filter removes both bacteria and viruses.
Sawyer PointONE™ Filtration
The PointONE™ filtration system is usually all you would need unless you are traveling internationally (developing countries) where waterborne viruses such as hepatitis and/or Polio are present. This system removes all harmful pathogens from your water.
Sawyer PointZEROTWO™ Purifier
If viruses are an issue, we offer the PointZeroTWO™ Purifier (0.02 micron absolute pores), the first and thus far only portable purification device to physically remove viruses which it does at a >5.5 log (99.9997%) rate, exceeding EPA and NSF recommendations. Due to the significantly higher level of filtration, PointZEROTWO’s flow rate is considerably slower than the PointONE™ filters.
North America vs. Third World Countries
In North America we do not have concerns about viruses in our water. They simply cannot survive. Viruses derive from contaminated human sewage and die shortly after entering a body of water. In Third World countries outbreaks have occurred due to poor treatment of sewage. Sewage without viruses can be handled by the PointONE™ filter. The only viruses with the potential to survive in water are hepatitis (which is rare) and Polio (which is extremely rare). You can contact CDC for information on virus outbreaks in areas for which you are traveling.

Although chemical treatment of water is the primary means of rendering raw water "safe for human consumption" it is not all that it is cracked up to be.
If you read the pages associated to the button below you will learn about the shortcomings of chemical treatment. The purpose is not to doom and gloom, but to make you aware so that you will prepare with more reliable alternatives.
The mini seminar focused on Water Purification both on and off-grid using purification units from RapidPure Filters, Sawyer and SurvivalStill.
Water is at the top of the list on Maslow's Heirachy of your needs for survival. On the December 22, 2015 show Will discussed water treatment and purification.
On the March 1, 2016 show Will interviewed Glen Meder regarding the SurvivalStill and covered ideas of distillation and desalination as well as the value of distilled water.
On the March 8, 2016 show Will interviewed John Ruprecht, the founder and owner of RapidPure Water Filtration one of Will's Top Picks in the water purification category. The systems components are manufactured in the USA, designed and sold by a family operated company in the heartland of the USA.
John started the company in response to a personal crisis that happened in 1985 when a neighbor's well failed testing during the sale of the property. The water in his and 59 others in his community was found to be so contaminated with PCBs that it was deemed unsafe for ingestion. John became very active in working as a liason to the Minnesota Pollution Control and Responsible Parties. He worked to help develop a resolution.
That kicked off a personal quest to provide reliable solutions for water purification.
