Survival instincts in humans help them survive through emergencies, calamities, and national disasters. If you are to make a list of survival elements needed by any human, water is in the top three. During emergencies such as floods, and drought, water available for drinking, cooking or bathing is contaminated. Microorganisms, chemicals, and other impurities. You can get water from algae infested pools, paddles, contaminated rivers, and other sources and clean it for use.

Having basic human survival skills are advantageous during such occurrences. Water filtration and purification techniques can be used in converting the contaminated water to safe water for drinking. Filtration is responsible for removing all solid elements and bacteria from water. Purification is a step further which removes viruses and chemicals that are present in water.

So, what is the difference between a water filter and a water purifier?

  • Water Filters

Water filters are more popular than purifiers. They remove impurities in water. These impurities include copper, lead, nickel, chlorine, and more compounds found in contaminated water sources. They also reduce bacteria and protozoa in the water though at a lower efficiency.

  • Water Purifiers

Purifiers remove all bacteria, protozoa, viral, and parasite contaminants present in water. Water purifiers are not easy to find, but manufacturers develop them in conjecture with water filters. This ensures all microorganisms and chemicals are removed from water in one process.
