The only purifier designed for safer sleep
Our patent-pending SafeFlow™ system gently sweeps away stagnant air — helping reduce buildup of CO₂ and other pollutants where your baby sleeps, all while keeping little fingers safe. No need for a separate fan.
Clean air is critical for babies’ development — stronger lungs, healthier brains, and more. But the air in our homes can be shockingly dirty.
That’s why we built Sereniby — bringing together a team of world-class engineers with 50+ years of experience designing high-end air purifiers.
It’s powered by the same medical-grade HEPA technology trusted by pediatric hospitals, rivals the most expensive purifiers on the market, and gives babies the clean, healthy start they deserve.
We created Sereniby based on the science.
"Children spend 80% to 90% of their time indoors and therefore are frequently exposed to pollutants in indoor air."
"Children's lungs are especially sensitive to the harmful effects of air pollution."
"... improvements in air quality were associated with statistically and clinically significant positive effects on lung-function growth in children."
“Air Pollution Puts Children at Higher Risk of Disease in Adulthood”
“Studies suggest that PM 2.5 [airborne particulates small enough to penetrate the lungs] can hinder children’s neurological development…”
Laser-Precise Sensors Monitor and Respond in Real Time
Sereniby’s advanced sensors measure air quality and temperature with scientific accuracy — detecting even subtle shifts that could impact your baby’s environment.
Smart alerts are grounded in pediatric-health guidance and trigger auto-purification when needed, ensuring your baby's space is a sanctuary for rest and healthy growth.
Sleep Lighting, White Noise, and Safety — All Built In
Sereniby’s gentle red night lighting supports natural melatonin production, while natural white noise helps soothe babies to sleep.
Designed with tip-over protection, no exposed fans, and a hidden power cord, it’s engineered for safety — and for the peace of mind every parent deserves.
A Long-Term Investment in Your Child’s Health
Unlike short-term baby gadgets, Sereniby is built to last — with a modular, adaptable design that transitions from nursery to playroom to shared family spaces.
It’s energy-efficient to help reduce your electric bill, and includes toddler-friendly features like rise-to-wake lighting for gentle morning routines.
Why Settle When You Can Have It All?
Everything they do — in one device. Sereniby has all you need to create a safe, healthy, restful, clutter-free environment where your baby can grow and thrive.

It is MORE sensitive than the Air Doctor that cost me 1000 bucks! There was wild fire 50 miles away from us and it was able to detect the particles in the air while the living room purifier failed to do so. It also circulates air which is crucial for safe sleep and it’s cute, especially for our baby's room. :)

Quality product that brings so much peace of mind. Set up was super easy and the app is very user friendly. I was amazed to see how high the pm levels were in my daughter’s room. Thankfully, it only took minutes for Sereniby to bring them down to a safe level. Now I’m obsessed with checking throughout the day! It has brought me so much peace of mind knowing that it’s keeping the air in my daughter’s rooms healthy and safe. Her favorite part is changing the color of the light. It has become part of our nighttime routine. :)
This is a quality air purifier worth every penny! I’ve tried many others that frankly just don’t work. I Highly recommend this product after testing many others. I also love that it was created by parents of little ones. They get it and thought of everything!

We can see and feel it working! We were looking for a way to improve the air quality in our sons nursery, and this product has truly exceeded our expectations. The difference is noticeable the air feels fresher, and its reassuring to know our baby is breathing cleaner air. Setup was simple, and I love how it blends seamlessly into the room with its minimalist design. We love the app and get tons of use out of it, but we also appreciate that you don't need the app to control it, which is useful for when grandparents babysit. Finally, we appreciate the gentle noise it emits... ended up getting rid of the white noise machine as this seems to be sufficient to block out background noise while he's sleeping.Highly recommend to any parent who wants a high-quality air purifier for their childs room!

Wish I had this with my first baby
We really love our sereniby. We use it in our toddler’s room. I did not have an air purifier with my first child. We feel better having her bedroom air purified with all of the winter colds she’s exposed to at school and pollutants in the city. Our daughter loves using it as a nightlight. It is very stable and safe for kids who may try to knock it over (like mine). We’re all very happy with our Sereniby!

As a family of physicians, we wanted a straightforward, reliable way to improve the air quality in our daughter's room. Sereniby has been great we like being able to check the PM2.5 levels anytime, and the alerts give us a heads-up if anything changes. It's exactly what we needed for their space.

Must Have For Any Nursery! I'm honestly so impressed with Sereniby and cannot believe I didn't invest sooner! I'm currently pregnant with my second and have gone through multiple air purifiers! They either didn't do the job or quit working after a while. Sereniby is incredible. The quality of air purification is above standards and it provides a real time reading. I also love the app and rise-to-wake feature for my toddler! My favorite perk? It's BEAUTIFUL! It's a piece I am proud to own and have been recommending it to everyone I know.

A WORLD OF DIFFERENCE!!!
Okay, I'll be honest. When my wife first wanted us to buy this, I thought it was just another gimmick. Well, I could not have been more wrong! This product is an absolute game changer!! The overall smell (and even feel) of the air as you breathe is a world of difference. I want one for every room!!

Peace of mind for baby's health & comfort
I don’t usually write reviews, but I want to share how much we love our Sereniby Air Purifier and the brand itself.
As a new mom, I’m always thinking (or TBH overthinking) about how to make our home as safe and comfortable as possible for our baby, and buying this product gave me so much peace of mind.
It was really important to me to know that the air my baby is breathing is clean. The fact that I can actually see the air quality in real-time on my phone is such a game-changer—I don’t have to guess whether the air is okay, I just check the app and adjust settings if needed. To be honest, I was shocked by the initial levels that his room had, and it really put my mind at ease to see the numbers go down as the purifier did its work.
The built-in option to turn on a red light has also been really nice when I check in on our little guy at night. It allows me to see what I'm doing without fully waking him up.
One of my favorite things that maybe shouldn't matter but does to me... It actually looks beautiful! So many air purifiers are ugly and easy to knock over, but Sereniby blends right in with the other furniture and decor in our nursery.
It was also super easy to set-up... so no reason not to get it!

Best air filter I’ve ever used
The Sereniby exceeded all expectations. From the look and feel, the setup, the mobile app, and the actual use and impact it has on our toddlers sleep… it’s amazing.
It’s something we recommend to all our friends and pregnant moms as they’re figuring out what they need for their nursery.

Absolutely Worth the Investment
I was hesitant at first because of the price, but Sereniby has exceeded all our expectations. I especially love the air-quality readings, and it's amazing to see how much they fluctuate through the day. The setting that automatically starts cleaning the air when the sensor detects that it's getting bad is so useful.

Revealed and then fixed dust issues
When we first got Sereniby, we were shocked at how bad the air quality was in our daughter's room. Running it helped, but the air would spike again every time we walked on her rug. Turns out, the jute rug was trapping a ton of dust underneath. After we removed it and did a deep clean, her room's air quality got better, and it's continued to get even better as we've consistently used over time. We honestly felt so bad, but we hadn't even known the problem existed before we got Sereniby. Plus, our daughter loves the rise light each morning (has to be purple for her to be happy).

Frequently asked questions
Why is air circulation important for babies?
Babies breathe more quickly than adults, making good air circulation essential for maintaining a safe sleep environment. Research indicates that using a fan in a nursery can promote healthy airflow, which contributes to safer sleep. Many pediatricians recommend incorporating a fan to support overall safe sleep practices and create a fresh, breathable space for your baby. Research shows the potential benefits of using a fan in your baby’s room.
What are PM2.5 particles, and how do the impact my baby's development?
PM2.5 particles are fine particulate matter that measure 2.5 micrometers or smaller in diameter. Due to their tiny size, they can penetrate deep into the lungs and even enter the bloodstream, causing various health issues. In babies, exposure to PM2.5 particles has been associated with respiratory problems, increased risk of allergies and asthma, and even neurobehavioral challenges. Learn more about the impacts of PM2.5 on your baby’s health here.
How will I know Sereniby is effectively purifying the air?
Sereniby is equipped with the most accurate PM2.5 sensor technology available. It provides real-time air quality read-outs both on the device and via the app, assuring you that your baby is breathing clean air.
