The filters were also tested under different flow rates and bed heights, and the results indicate that the PVA filter performance is slightly affected by these variables. The results of the study have shown that the 3D printed filters are effective, with removal efficiencies comparable to those of commercial filters. The filters were then tested for their ability to remove arsenic from water, and the arsenic removal efficiency was compared to that of commercially available filters. The filter was designed using a computer-aided design software and fabricated using a 3D printer. The second method is a 3D printed PVA filter with an iron oxide coating as well. Iron oxide absorption treatment is a chemical treatment method where arsenic absorbs onto iron oxides and create large particles that can be mechanically filtered from water. The first filtration method is made of sand with an iron oxide coating. In this study, our team developed and tested two types of filters and compared performance. Research and development in water filtration can change the lives of millions across the world.

Arsenic consumption can cause cancer, skin lesions, cardiovascular disease, diabetes, and can affect children's cognitive development (WHO).
In the United States, approximately 2.1 million people have arsenic in their drinking water (USGS).
An estimated 140 million people, over 70 countries, are drinking water contaminated with arsenic (WHO).
