KEIYO's AN-S152 Portable Water Purifier Revolutionizes Emergency Preparedness

Confirming Initial Removal Performance of PFAS



In a recent announcement, KEIYO Co., Ltd., based in Minato, Tokyo, has unveiled two significant initiatives regarding their portable electric water purifier, the 'Anywhere Safe Water AN-S152'. This device aims not only to assure clean drinking water during emergencies but also comes at a more accessible price point for preparedness.

The first initiative focuses on the confirmation of the initial removal performance of three PFAS substances conducted by a third-party testing organization. The results demonstrated impressive removal rates shortly after use, which are crucial for lowering exposure to these harmful chemicals in drinking water. Here are the details of the initial removal rates confirmed:
  • - PFOS: Over 92%
  • - PFOA: 88%
  • - PFHxS: 90%

These results indicate that the AN-S152 effectively reduces the concentration of PFOS, PFOA, and PFHxS found in water, thereby limiting the potential intake of these substances when consuming the water.

Features and Design



The AN-S152 is not only designed for home use but is also ideal for camping, vehicle travel, and emergency situations. Its compact design (approximately 440g) allows for easy transport, making it a versatile solution for various environments. Within just ten minutes of starting its operation, it can filter approximately 700 mL of water per minute, meeting urgent needs for clean drinking water. Additionally, the unit is equipped with a 5200mAh battery, providing emergency power for smartphones, and features an integrated LED light and SOS signal capability. It supports USB Type-C and solar charging options, ensuring that users remain prepared in different situations.

Safety and Standards



The AN-S152 has received NSF certification, confirming its compliance with international safety standards and suitability for public health. Additionally, it is in accordance with Japan's water quality inspection requirements by the Ministry of Health, Labour and Welfare, and has attained PSE certification. This commitment to safety ensures that consumers can trust the product for their emergency needs.

Price Adjustment for Accessibility



To enhance the emergency preparedness of a broader audience, KEIYO has adjusted the retail price of the AN-S152 to 14,800 yen (tax included) from the previously estimated price of 19,800 yen (tax included). This price reduction makes the water purifier approximately 25% more affordable, thus facilitating its inclusion as a crucial item in homes, vehicles, and emergency backpacks. It serves as a supplementary measure for filtering alternative water sources during times of water outages while advising users to maintain a stockpile of safe drinking water.
