520			_aThis study addressed the declining quality of natural bodies of water, concentrating on the micropollutants contained within it and purifying the with filtration by inventing a water filtering machine called the Machine of Nature Aquafilter (M.O.N.A). This study aims to present the possibility of automating the cleaning of ecosystem, attempting to clean a pond to start off as a blueprint. This study aims to determine if the machine M.O.N.A. was capable of filtering the micropollutants from the water efficiently to improve the purity of the water. The Experimental Research methodology, specifically the Pretest Posttest design was utilized in this study. The Friedman Post Hoc Wilcoxon test was used as the statistical test for the study. The Friedman test will check if there was a significant difference among the overall set of data and the Wilcoxon test will check if there was a significant difference between the pairs of set of data. Bonferroni adjustments was used in the results from the Wilcoxon test because there are three comparisons. There was an statiscally significant difference in the water quality depending on how long the water was filtered. Median (IQR) perceived water quality for the different time intervals were determined. There were no significant differences between each group, despite an overall improvement in the water quality. The researchers concluded that the machine was ineffective in serving its purpose and made recommendations for future researchers to focus more on tweaking the machine's components to effectively filter water.
