"My sons and I used this filter during our 3-day adventure on the Colorado River, and it consistently provided us with clean water for multiple bag fills. We were very satisfied with its performance and reliability and plan to get another for future trips."

"I tried this out for a Girl Scouts event, and it turned dirty pond water into clear, safe water fast enough to keep the kids interested. The demonstration was a hit with both the girls and onlookers. After filtering, the water was odor-free except for a faint chlorine smell, and I felt safe tasting it. Now I make sure to keep a few packets in my emergency kit."

"When I tested these in the field, I found the packets work exactly as promised—the coagulation is even a bit fun to watch. However, the packet size is really for large containers and not ideal for typical 1-liter bottles, so measuring out smaller doses is tricky without extra tools. I’d love to see a version for smaller containers, but overall, it’s a solid product for emergency preparedness."

All other SteriPEN models my group used worked perfectly, but the Ultra was sometimes finicky."
