Type 1 water, also known as ultrapure water, is water that meets the strictest levels of purity for usage. "Type 1" refers to the water specification regarding the level of contaminants allowed within the water, placing it at a higher level of purity than "type 2" or "type 3" water, for example.
Water filters designed to provide Type 1 water meet the American Society for Testing and Materials (ASTM) guidelines, ensuring a resistivity of >18 MQ-cm, a conductivity of <0.056 uS/cm, sodium & chloride PPB of < 1, and <50 ppb of Total Organic Carbons (TOC). ResinTech type 1 water filtration systems can help you achieve these standards easily and affordably.
