KYRESA Water Purification Kit - Enough for 500 PET Bottles To Safely Drink River Water In the Event of a Disaster

This water purification set allows anyone to easily purify river, pond, and rainwater during disasters, making it drinkable. One KYRESA set can produce the equivalent of 500 500ml bottles (250 liters) of drinking water. Regarding the expiration date: This product was created with the desire to save as many lives as possible, and is designed to be usable even in the event of an unpredictable disaster. Therefore, we carefully selected the contents of the set to ensure safe use even long after the manufacturing date, as it would be pointless to use it because it was out of date. Therefore, it can be used semi-permanently if unopened. After opening this product, the KYRESA powder packs inside the box are also divided into 10 individual packs, and as long as the individual packs are unopened, they can be used at any time. We are confident in the quality and safety of our products, and their effectiveness is not affected by the expiration date. We hope you will use them with confidence.
