Pureit Gravity Classic delivers water that is safer than boiled water. It features a 23-litre capacity and a long-lasting filter with a lifespan of up to 3000* litres. Enjoy safe, great-tasting water. The device ensures that every drop is pure and has a natural taste. Multi-Stage Purification: Uses programmed germ-kill technology, Germ Kill Protection: Helps reduce bacteria & viruses, Activated Carbon Filtration: Improves taste & reduces chlorine odor, Microfibre Mesh Prefilter: Removes larger particles and suspended solids, No Electricity Required: Operates purely by gravity flow, Auto Shut-Off: Stops water flow when purification kit expires, Germkill Kit Life Indicator: Alerts when the kit needs replacement. First-Time Use Instructions: Before drinking water from your new purifier, perform 2 complete flush cycles to prepare the filtration system for use. To begin, remove the lid and slowly pour approximately 9 liters of water into the top chamber through the microfiber mesh, taking care not to add more water once the transparent lower chamber is full, as this may cause overflow. Once the lower chamber is full, open the tap and completely drain the water, then repeat this filling and draining process a second time to complete both flush cycles. After these 2 flush cycles are complete, your purifier is fully conditioned, and the filtered water is ready for everyday drinking and use.
