CDC water filtration guidelines

Read This Before Use

The Twin Tech Tactical Survival water filter can only filter solids, certain chemicals and pollutants from the water you’ve collected. Activated carbon is most commonly used to filter water. It improves water quality, eliminates unpleasant odors, and removes chlorine and other pollutants. However, it’s not sufficient for eliminating certain toxic organic compounds, significant levels of metals, fluoride, or pathogens.

WASH ALL COMPONANTS WITH SOAPY WATER BEFORE USE.

Without unique filter media materials or additional filtration, the Twin Tech Tactical activated carbon will not filter:

  • Radionuclides
  • Most microbiological contaminants, including bacteria, viruses, cysts, coliform, protozoa, and other microorganisms
  • Significant amounts of heavy metals, copper, or iron
  • Inorganic pollutants like asbestos, and arsenic
  • Healthy minerals, such as calcium, potassium, and magnesium
  • Significant amounts of hydrocarbons or petroleum distillates
  • Dissolved solids, including minerals, salts, or metals, such as iron that aren’t usually considered contaminants

This is why it is of the utmost importance to either BOIL your filtered water at a rumbling boil for at least 3 minutes after you’ve run it through the filter. If you are unable to boil your filtered water, then you MUST disinfect your filtered water (before drinking) with household bleach using the following procedure provided by epa.gov:

  • Disinfect water using household bleach, if you can’t boil water. Only use regular, unscented chlorine bleach products that are suitable for disinfection and sanitization as indicated on the label. The label may say that the active ingredient contains 6 or 8.25% of sodium hypochlorite. Do not use scented, color safe, or bleaches with added cleaners. If water is cloudy, run it through the filter again, until it runs clean. It should run clean thereafter.
    • Locate a clean dropper from your medicine cabinet or emergency supply kit.
    • Locate a fresh liquid chlorine bleach or liquid chlorine bleach that is stored at room temperatures for less than one year.
    • Use the table below as a guide to decide the amount of bleach you should add to the water, for example, 8 drops of 6% bleach, or 6 drops of 8.25% bleach, to each gallon of water. Increase the amount of bleach by 50% if the water is very cold.                      
    • Stir and let stand for 30 minutes. The water should have a slight chlorine odor. If it doesn’t, repeat the dosage and let stand for another 15 minutes before use.
    • If the chlorine taste is too strong, pour the water from one clean container to another and let it stand for a few hours before use.
