16. Conclusion
The MMSWF prototype worked properly based on the defined
features.
The developed prototype is portable and low-cost working
prototype
The water filter was also able to remove impurities such as dirt
and other solid particles during the filtration.
The pH sensor was able to get the input and output value of the
water before and after the filtration process.
The researchers were able to compare the input and output value
of the pH MMSWF and the digital pH meter.

17. Recommendations
Include a BioSentry sensor, which detects bacteria and other filthy
organisms.
If implemented, MMSWF should also have a UV purifier for killing the
bacteria.
Add volumetric andTime monitoring Features.
Use MMSWF in a place where the temperature will not exceed 30
degrees Celsius.
Limit the usage of the filter up to 2 L of contaminated water only.
To assure the quality of water, use only water that is stored in closed
barrels and avoid using unsecured containers.
