Do I need to filter water before putting it into storage?

Why Filter Water Before Storage

When storing water for an extended period, it’s essential to ensure it remains safe for consumption. Bacteria like E. coli and Giardia can multiply rapidly in temperatures between 40°F and 140°F (4°C and 60°C), contaminating the water and posing significant health risks. A water filter can remove up to 99.99% of bacteria, viruses, and contaminants, making it a crucial step in water storage preparation.

Choosing the Right Filter

Select a filter with a minimum pore size of 0.2 microns, as this will effectively remove most bacteria and viruses. Consider a filter with a high flow rate to minimize the time required to filter large quantities of water. For example, a filter with a 1-gallon-per-minute (GPM) flow rate can process 1,440 gallons of water per day. Look for filters certified by reputable organizations such as NSF International or the Water Quality Association.

Storage and Maintenance

After filtering your water, store it in a clean, food-grade container with a tight-fitting lid. Ensure the container is made of a material that won’t impart flavors or contaminants to the water, such as stainless steel or BPA-free plastic. Regularly inspect the storage container for signs of leakage or contamination, and replace the water every 6-12 months or as recommended by the manufacturer.
