Hi there...I can understand your concern. But drinking filtered water will have no effect on your knee pain. Knee pain at your age could be due to obesity(ideal weight for your height is around 45 to 50kgs), osteoarthritis, ligament or meniscus injury. Firstly you need to start reducing your weight. Consult a dietician for that. Secondly you need to examined clinically for the knee joint pain. So kindly consult a orthopedic for further evaluation.
