Single-use plastic bottles take nearly 450 years to decompose, accumulating toxic microplastics in soil and water ecosystems globally. Research reports reveal that many bottled water brands contain microplastics, exacerbating concerns about water quality beyond the tap.
For environmentally conscious consumers, home water filtration systems offer a middle ground by reducing plastic waste and improving water quality. These systems use multi-stage filtration, including reverse osmosis (RO), ultraviolet (UV), and ozone treatments for purification. Although initial installation costs range between 4,000 to 10,000 Thai Baht, the long-term health benefits and cost savings appeal to many households.
