Cheapest drinking water filter. A much-needed innovation.

We all know that drinking clean water is one of the most basic need for all human beings. The bad news, however, is that not everyone gets to drink clean water.

Niranjan Karagi a 23-year-old mechanical engineer thought that water is not a luxury, but a need- a verybasic need.  Niranjan was on a mission not only to provide clean drinking water to the masses but at an affordable cost.

After thinking of various options settled down to making a simple small Filter “NirNal” that could fit into any standard plastic bottle.

What is so Unique?

“Nirnal” Filter costs just Rs 30 if the GST is not added and it can be used for 100 times and is easily portable. NirNal removes almost 99% of the bacteria and other disease-causing water contaminants effectively. NirNal can also be used for filtering unfiltered ground or tap water within the bottle. This device has a porous housing which contains activated carbon, ultra-filtration and other filter materials which include polypropylene cotton, filter paper, colloidal silver etc. The device can be easily attached and removed from the water bottle as a unit. The portable water filter device is fluid-tightly attached to the bottleneck such that water does not pass through the bottleneck.
