Glass for a pool filter is worth it. Glass filter media is a popular alternative to traditional filter sand because it offers several advantages. It provides superior filtration, capturing smaller particles and producing cleaner water. Glass media also lasts longer, with a lifespan of up to five years, compared to the two-year lifespan of filter sand. It is also environmentally friendly, as it is made from recycled materials. Additionally, glass media requires less maintenance, as it does not clump or deteriorate like sand does. Furthermore, it improves water circulation and enhances the efficiency of the pool system. Overall, using glass filter media in a pool filter is a worthwhile investment for better filtration, longer lifespan, and easier maintenance.
