What is the Difference Between a Cyst, Bacteria and Virus?

The difference between the three most common pathogenic (capable of causing disease) microorganisms are:

Bacteria: single celled organisms which lack well defined nuclear membranes and other specialized functional cell parts and reproduce by cell division or spores. Bacteria may be free living organisms or parasites.

Cyst: a capsule or protective sac produced about themselves by many protozoan, as well as some bacteria and algae as preparation for entering a resting or a specialized reproductive stage. Generally, 2 - 50 micron in diameter.

Virus:  a parasitic infectious microbe, composed almost entirely of nucleic acid, which can cause disease(s) in humans. Viruses can only reproduce within living cells. They are 0.004 – 0.1 microns in size about 100 times smaller than bacteria.

Still unsure that the Outback Ready is the answer for you? Below is a comparison chart of emergency use products which will help you make a decision. Many of these products are clearly NOT practical for emergency preparedness, food/water storage, or for other disaster relief and survival applications, as many of these devices are only designed for recreational use.


Outback Water Filter FAQs

Does the water produced by the Outback taste good?

The Multi-Media Filter Cartridge provides secondary treatment, including reduction of certain off tastes and odors. Performance can vary depending on the substances present in the source water and operating conditions. See How the Outback Ready Works for the full role of each filtration stage.


How much water does the Outback Ready produce?

The Outback Ready is rated to produce up to 24 gallons of filtered water per day. This is a daily-output figure, not a total filter-capacity claim. See the Outback Ready product page for current pricing and availability.


What is the "nano filtration" used in the Outback system?

The Nano Pre-Filter is the fine-media stage in the Outback Ready's four-stage configuration.


Is the Outback system easy to use?

Yes. Source water is poured through the pre-filter net into the upper container, and gravity moves it through the remaining stages into the lower container for dispensing. See the current instruction manual (PDF) for exact assembly, initial use, and setup steps.


What test method was used to determine these reduction figures?

The figures come from third-party laboratory testing of the complete Outback filtration configuration. See the published test-results summary (PDF) for the full methodology and conditions.


Do all four filtration stages have the same reduction rate?

No. The published 99.9999% bacteria, 99.99% cyst, and 99.99% virus reduction figures apply to the complete four-stage system as tested — not independently to each individual component. See How the Outback Ready Works for how the four stages work together.


Has the Outback had third-party testing done?

Yes, These are third-party test results, independently verified through lab testing.


Can the Outback Ready remove salt from water?

No. The Outback Ready is not designed to remove salt, and saltwater or brackish water should not be used as a source. See How the Outback Ready Works for the complete list of approved and prohibited water sources.
