【Disaster Preparedness】You can drink river water freely! The water purifier equipped with solar panel & light is incredibly reliable
Securing drinking water is a top priority during outdoor activities and emergencies. However, clean water isn't always available. That’s why the "Electric Water Purifier", which transforms river water or rainwater into safe drinking water, is a new option to consider.
Drinking water not only for "buying" but also for "making" preparations
Have you ever experienced packing multiple bottles into your backpack when there was no water source nearby while camping or hiking (the author has experienced this as well)? It's heavy, bulky, and creates waste. However, securing drinking water is a must, especially in outdoor activities and even more so during disasters.
What caught my attention is KEIYO's portable electric water purifier "AN-S180," which can transform river or pond water into drinking water on-site. I found the idea of "not just buying and preparing water, but having a state where it can be 'made'” to be reliable.

Filter performance capable of purifying approximately 1600 bottles
It is equipped with Ahlstrom's Disruptor filter (high-precision filtration filter). One filter can purify about 800 liters, equivalent to roughly 1600 bottles of 500ml water. Even for a family of four going on a 2-night, 3-day camping trip, the capacity is more than sufficient.
The filter is replaceable, so once it's used up, you just need to switch to a new one. The design allows the main unit to be used for a long time. Since it's electric, there's no need for the physical labor of a manual pump. In addition to Type-C charging, it supports solar charging, making it safe to operate even in places without a power source.

One device for light, SOS, and smartphone charging
Not only does it have water purification capabilities, but it also features an LED light, SOS mode, and even a charging function for smartphones. It can serve as a flashlight during outdoor activities and as an emergency light or signal during disasters. Being able to perform multiple roles with one device is a valuable asset for campers looking to reduce their load and for families with limited storage space.
A portable preparedness option for your car
Emergency supplies are meaningless if they aren’t readily available when needed. The stockpiled water stored deep in your closet may have expired without you realizing it. With this compact water purifier, you can cover both daily outdoor activities and emergency situations just by keeping it in your car. Why not prepare one as a trusty companion for family outdoor adventures?
