What is a gravity based water purifier?

Gravity water purifiers work on the principle of gravity. In a gravity situation, everything comes downwards. Like other things water also flows down always. This happens due to the gravitational pull and it was discovered by Issac Newton. 

How does a gravity based water purifier work?

A gravity based water purifier has two chambers: the upper chamber and lower chamber. As the name suggests, the gravity of the water pulls down the water from the upper container to the lower container.

Water from the upper chamber comes down to the lower one. As the water comes down, it is passed through some activated carbon or charcoal filters. The carbon filters absorb the harmful impurities of water purifying it.

A gravity based water filter has three major components: 

  • Activated carbon filter for removing pollutants, parasites and impurities.
  • Microfiber mesh to get rid of the dirt that is visible to the naked eye.
  • Polishers to drive out dangerous chemicals like chlorine etc.

Advantages of Gravity based Water Purifier

  • Works without electricity
  • No need for a constant electricity supply and piped water
  • Saves electricity cost
  • Can be transported and used in remote villages also
  • A blessing for the place with frequent load shedding
  • Very affordable and cost-saving

Disadvantages of Gravity based nonelectric Water Purifier

  • Can not remove TDS(Total Dissolved solids) higher than 300 ppm.
  • Can not kill all the germs and bacteria
  • Not suitable to eliminate harmful arsenic and fluoride
