Hi Grace, thank you for your kind words! Our technology uses a sunlight-induced chemical photocatalysis process, so the water is not actually heated. Our system is tolerant to turbid water, albeit for large particulates and mud we recommend the use of tea strainers (which are cheaply available and commonly used in India) or folded cloth/saris (which is a commonly utilized tactic in India) to remove it. Since we use a catalyst, we do not have parts that require regular replacement, although wear and tear will eventually accumulate over a period of several years, leading to our device's estimated lifetime of 5-10 years. As for the statistic in our video, it refers to all women worldwide (it is certainly alarming!). Again, thank you for reaching out and for showing your support!
