Water is essential. Not only do you drink it, but it is used for hygiene, cooking, and cleaning. It is important to have water stored for an emergency, but it is impossible to store as much water as you need. Once your water reserves run out, you may need to use an outside water storage source. How do you ensure that your water is clean?
What could be in your water?
The dirt, sand, and large particulates that you can see in the water. Protozoan Cysts: Common ones are Giardia and Cryptosporidium. These are relatively large, but can’t be seen by the naked eye. They can withstand harsh conditions. Typically sized at 1 to 15 microns.
Common bacteria are E-Coli, and Salmonella. The flourish in warmer environments but can be very common. Smaller than Protozoan at 0.2 to 5 microns in size.
Most common names are Norwalk and Hepatitis A. These are extremely small at 0.02 to 0.2 microns and are tricky to remove from water. Chemical: Chemical contamination can come from natural or man-made sources. Common ones are bleach, pesticides, and salts. There are many methods for cleaning water, knowing which methods will work the best for you, is very important.
The act of removing something unwanted from a liquid. Filters are used to remove Protozoan Cysts from your water. They also remove Turbidity and can improve the taste of your water by removing some chemicals since most filters contain carbon.
Since the pore size of these filters are smaller (down to 0.2 microns) than filters, they can remove Turbidity, Protozoan Cysts, and Bacteria. Some very large viruses may also be filtered out, but the smaller ones will pass through. These also commonly contain carbon and will help remove some chemicals to improve the taste of your water.
Purification will kill the micro-organisms in your water, but doesn’t actually remove anything. This method will kill Protozoan Cysts, Bacteria, and Viruses, but chemical and turbidity are still present in your water. Not all filters and water treatment are created equal. Use a combination of Purification with a Filter or Micro-Filter to insure that you and your family are drinking clean water.
