Water Filters

It has always been a great concern to me what type of water to drink. It’s something so small and detailed but it’s very important. 75 percent of our body is made from fluids and we need to drink an average of 1.9 liters of water a day to stay in good hydration. And if I don’t invest in a good water filter then a lot of problems can happen. I think we can all agree that drinking tap water is out of the option. There are a lot of scientific articles out there that try to convince us that it’s “great for us” and all that because it has fluoride and helps our teeth or whatever. These articles sadly don’t mention the chlorine and chloramines level in the water used to cleanse the water from diseases. Not to mention the random minerals in the water. I want to design or research a water filter that will create an optimal experience for the consumer. Because so many companies out there are just trying to get our money. They don’t really care about what is truly better for the consumer or not. I have no idea why these companies are so short sighted. I believe that companies should add value to society. Currently, there is no really good water filtration system in the market that can be cost effective. So I really want to focus my research on creating and researching an optimal way to filter water yet do it at a reasonable cost. And I also want to make it easy for the consumer because water is such an important part of our health and lives.

I have done some research on which type of filter would be optimal. There are several kinds. The reverse osmosis system purifies the water by forcing it through a tiny membrane and drawing out bacteria, salt, minerals. It is very expensive and it also takes all the healthy minerals out of the water too! The water distiller system boils the water and condenses the water again so all the bacteria minerals would also be gone. It’s also very expensive and takes out all the healthy minerals. Another type of water filter is the charcoal filter. The benefits of this type of filtration is that it filters out bacteria and bad elements like lead mercury. The carbon charcoal will bond with all the heavy metals and filter them out of the water. It also retains the good minerals. The filter has to be changed every 6 months or so. This is the type of filtration Brita filters are based from. However, even though Brita filters make tap water significantly healthier, the filters on them are so small. It is built for more of convenience rather than being a good filter. The ceramic filter filters our bacteria and mineral because they have microscopic fossilized one celled algae that are so tiny they only let through few particles. Out of all these options, I think that ceramic and charcoal filters would be the best option for the general consumer. They are easy to use and not expensive. I would not recommend the other ones because they are far too expensive and a lot of users have listed a lot of problems on them.

Bamboo Charcoal
Another type of filtration system uses the bamboo charcoal, a substance used in Asia for thousands of years starting with 1400 AD in the Ming dynasty of China. It has been listed as having miraculous properties of releasing negative ions the air – which creates a healthier environment. And it also filters water. But here’s the amazing part. It filters water and adds vital minerals the body needs. I found an article here Bamboo Charcoal. I really want to do more research into how these various ways of filtration can be combined to create and generate a good experience for the consumer. I am thinking that if we combine the ceramic, charcoal, and bamboo charcoal filter. It will succeed in producing a cost effective solution to filtration and improving the general health because the bamboo charcoal adds minerals back into the water.

  1. Tewei - This sounds very interesting. My only concern at this point is whether you have enough material for the entire paper. I'll trust you, though - perhaps you have much more than enough. I do not know anything about this topic, but let me know if you want to talk about anything along the way.
