Quick Answer
Proper storage for filtered reverse osmosis (RO) water requires a clean, airtight container, such as a food-grade plastic or glass bottle, with a tight-fitting lid to prevent contamination and exposure to air, light, and bacteria.
Storage Container Requirements
When selecting a storage container for filtered RO water, ensure it is made from food-grade materials such as BPA-free plastic, stainless steel, or glass. These materials are resistant to leaching chemicals into the water. Avoid containers with a history of exposure to chemicals, as they can contaminate the stored water.
Storage Container Size and Labeling
Select a container with a capacity of at least 1 gallon (3.8 liters) to minimize the number of containers needed, reducing storage space and handling requirements. Consider labeling the container with the date the water was filtered, the type of filtration system used, and any relevant handling instructions.
Storage and Handling Techniques
Store the container in a cool, dark place, such as a pantry or cupboard, to prevent exposure to direct sunlight and heat that can promote bacterial growth. Avoid storing the container near chemicals or strong-smelling substances that can contaminate the water. When handling the container, make sure to wash your hands before and after opening the container to prevent cross-contamination.
