Filter vs. Filter

What is your project about? The LifeStraw Water Filter and how people say it kills 99.999999 percent of bacteria and how it says it on the package and Homemade Water Filters to see if they are better than the LifeStraw. Why did you choose this project? I chose this project because I thought about how a lot of people said the LifeStraw kills 99.999999 percent of bacteria and how it says that on the package so I wanted to test that theory to see if it is true so I put the LifeStraw against Homemade water filters to see if that theory is true. What was your result/overall conclusion? My results were that the LifeStraw did better both times that I tested it. I used a TDS Meter to test it. There were either 1 or 2 homemade water filters that were just 1 TDS result above the LifeStraw. In my conclusion I said the LifeStraw would be a better option to pick if you needed a Water Filter on a hike or something but if you did not have access to one or you can’t afford it a homemade water filter would be a good option to because they both did well and they both removed most the bacteria out of the dirty water. Why is your project important? My project is important because it could help people who don’t have water that is clean or good drinking water and have to drink out of lakes, ponds, streams or oceans they could either get the Lifestraw and use it but if they can’t afford it or can't get it in any way then making a homemade water filter could be a next good option because the materials to make it can come from almost anywhere in the wild.

  1. Great research question! Another control you could add is tap water with no filter and measure with the TDS to see what level we normally consume.

  2. A good project starting with a good question. Pictures were helpful. Keep up you interest in science.
