Do the filters remove viruses?

The short answer is no.  Viruses in water are rare but dangerous.  The best option would be to find another water source if possible.  If that is not an option, then we recommend adding 1 teaspoon of bleach per gallon of water.  The chlorine bleach will not harm the BugOut Water filter.

Viruses are microscopic and most filters are ineffective against removing them from the water as a result.  Boiling, UV treatment, and distillation are the only proven treatment methods for removing viruses, besides using chlorine bleach.  Many filters claim that they remove viruses, but produce low volume rates.  Others make the claim without any reliable data to prove their efficacy against viral removal.


Have these filters been tested?

Yes.  Ceramic filters have a long track record of success by several providers.  Notable and credible institutions have tested the filters used in BugOut® Water Systems and confirm the findings listed above.  These institutions include, but not limited to:

  • USA AEL Laboratories
  • USA Johns Hopkins University Laboratory
  • ISA Analytical Food Laboratories
  • Abbott Laboratory South Africa
  • University of Chihuahua Mexico

In addition, the filters meet the following standards:

  • National Saitation Foundation (NSF) Standards 42 & 53
  • ISO 9002 Quality Standard
  • British 5750 Quality Standard
  • England’s Water Research Council (WRC) Performance Standard


What is the difference between percolation and in-line filters?


How much water do I need per day?


Isn’t water storage a better method to readily available water?


How long do BugOut® Water Filters last?  How do I clean them?


 Can I stop using the filters and use it again?  Can I use it multiple times?

Yes, you can!  The filters are silver impregnated which prevents bacteria growth during “shelf” time.  We recommend that you let the filter air dry, then store.  The filter will continue to be effective if the filter’s wall integrity is maintained.


Can you estimate the total number of gallons that can pass through the filter before it has to be replaced?

If proper care is taken with the filters, including cleaning, they can last through hundreds of gallons. Variables include the quality of water, mineral contents, and overall amount of particulates in the water being filtered.  With proper maintenance, a filter can be used regularly for up to six months.


 What are the strengths of BugOut® Filters vs. others filters?

If you can access most water sources, the filters will provide an endless supply of clean/potable water.  Filters, such as the BugOut® systems, have a cleanable pre-filter and ceramic filter that can be cleaned 100+ times.  Their filtration efficacy against contaminants is top-class and tested by top institutions.  BugOut® Filters are disaster and crisis proven and used by humanitarians in 60 countries and are very cost effective.
