About Sereniby

Sereniby was founded by parents who, like many, wanted the very best for their baby — but couldn’t find an air purifier that met the high standards needed for a nursery. With backgrounds in pediatric healthcare and technology, we set out to create something better. Indoor air can be 5x more polluted than outdoor air, and research increasingly links air quality to babies’ cognitive and lung development. Yet most purifiers weren’t designed with babies in mind, leaving parents struggling with confusing options that fail to measure air quality, don’t circulate air effectively, and add clutter to the nursery. Sereniby solves this with medical-grade HEPA filtration, ultra-precision air quality monitoring, and patent-pending Safe Sleep airflow technology — gently circulating clean air while keeping little fingers safe. Thoughtfully designed for parents, our smart controls integrate air purification, white noise, and night lighting into one seamless experience. We built Sereniby because no other purifier was good enough for the job of protecting a baby’s health. Now, we’re helping parents everywhere create the healthiest sleep environment possible.Read their story
