Introducing the New Baby Nasal Aspirator: Mercy Pot S-505 for Comfortable Care

Mercy Pot S-505: Revolutionizing Infant Nasal Care



Seastar Co., a leader in the development and sales of medical devices, has proudly announced the launch of its latest product, the Mercy Pot S-505, on June 15, 2026. This innovative electric nasal aspirator combines the strong suction power of traditional models with the portability of handheld devices, catering specifically to the needs of modern parenting.

Background of the Mercy Pot Series


Having sold over 6 million units, the Mercy Pot series is not just a mere childcare product; it has earned its place as an essential tool in household nasal care. It has been implemented and recommended by over 2,000 pediatric and ENT clinics across Japan. In recognition of its effectiveness and design, the Mercy Pot has received numerous awards including the 'Mama Rikuuchi Grand Prize' and the 'Mother’s Selection Award' in Japan, as well as the 'Product of the Year Award' and 'Top Choice Award' in the United States.

For infants who cannot blow their own noses, nasal congestion can significantly impact their sleep, feeding, and overall mood, creating additional burdens for caregivers. Traditional electric nasal aspirators, while effective in suction power, often lack portability, and handheld devices frequently struggle with effective suction, making care less convenient. Moreover, the maintenance after use can serve as a hurdle for consistent nasal care at home.

Addressing Market Challenges


Recognizing these challenges, Seastar Co. aimed to redefine nasal care by focusing on three crucial aspects: suction strength, portability, and ease of cleaning. The result is the Mercy Pot S-505, designed to blend the substantial performance of a stationary unit with the convenience of a handheld device.

Key Features of S-505


  • - Lightweight and Compact Design: Weighing significantly less than its predecessor, S-504, at approximately 290 grams compared to 800 grams, the S-505 is incredibly lightweight and compact (W95×D52×H114mm). This design allows for easy movement around the home and effortless portability during outings—making it accessible when needed.

  • - Dual Power Source: The S-505 operates both on AC power and batteries, ensuring convenience regardless of the environment. This flexibility enables parents to provide immediate care in various locations—be it living rooms, cars, or even during power outages.

  • - Enhanced Suction Power: Despite its smaller size, the S-505 boasts an impressive suction capability of up to -77kPa, comparable to larger stationary models. Additionally, it offers three adjustable suction levels to accommodate the varying needs of infants.

  • - Simplified Maintenance: To reduce the typical maintenance burden, the S-505 features a straightforward design where only the mucus collection cup and silicone nozzle require washing. It supports boiling disinfection methods and steam sterilization for easy cleanup.

  • - Affordable Pricing: Priced at 7,980 yen (tax included), the Mercy Pot S-505 is designed to be a financially viable option for families seeking reliable daily nasal care solutions without overspending.

BabySmile's Commitment to Safety


In line with its dedication to child safety, BabySmile prioritizes non-toxic materials. The S-505 is made from BPA-free materials, ensuring the product is safe for infants.
