Yes, the one I know about is called " Water Filtration Bottle", one of Aerotek Scientific products that filters all unwanted particulate matter from unclean water we drink. Depending on the mesh size, bacteria organism that mix up with the water are also filtered. I was to market this filtration bottle in Nigeria in year 2000. I did market survey and found out that most people could not afford it. Only a handfull could. The demand was not there because the public were unaware and not educated enough for the supply. A consumer told me that she could buy it and drink water from that bottle, but what if she forgets one day to take it to work or function and drinks ordinary tap water provided, she could eventually get sick. Someone who only drinks tap water all along would still be okay because she has built immunity and has resistance level fighting against microbs from drinking water, ( this I know anyways).
My findings: To make this fitration bottles affordable to the masses and get it installed right from the start in our plumbing system just like most homes in the United States. To add this fixture to the cost of building and plumbing work done in any new and/ or old building. Builders and Environmental Protection Agencies should sit together and discuss ways to meet the need of the consumers to ionic fitration bottles and to educate the public on the importance of this scientific product.
Most homes boil their water before drinking. The educated ones saw the need for the fitration bottles but want it at a cheaper price. Also, it would be best if the containers come in plastic form than glass for easy shipment and cost effective too. I had a limited time to do this assignment and did not get to all concerned. There was need for advertisment on TV, radio and other forms of mass media, which cost money.
