SUMMARY

The discussion focuses on creating a cost-effective water filter using a 25nm cloth, inspired by the LifeSaver bottle, which retails for $139. Participants emphasize the need for clarity regarding the material composition of the 25nm cloth and suggest exploring reverse osmosis filters as a viable alternative. The conversation highlights the importance of selecting an appropriate substrate for the cloth and considering the size requirements for effective filtration. A specific product link for a reverse osmosis membrane cartridge is provided for further exploration.

PREREQUISITES
  • Understanding of filtration technologies, specifically reverse osmosis.
  • Knowledge of material properties relevant to water filtration.
  • Familiarity with the LifeSaver bottle and its filtration capabilities.
  • Basic skills in DIY water filtration system assembly.
NEXT STEPS
  • Research the properties and applications of 25nm filtration materials.
  • Explore reverse osmosis filter systems and their components.
  • Investigate suitable substrates for attaching filtration materials.
  • Learn about the design and assembly of custom water filtration systems.
USEFUL FOR

This discussion is beneficial for DIY enthusiasts, environmental engineers, and anyone interested in developing affordable water filtration solutions.

I am looking for 25 nm "cloth" (I'm using that term loosely) my goal is to create a cheaper water filter similar to "LifeSaver bottle" (https://en.wikipedia.org/wiki/LifeSaver_bottle) which is $139
 
Engineering news on Phys.org
That is not a very well defined question.
25nm of what? A metal?
What kind of substrate should it be attached to?
What size do you need?
