is on sale for $200 for a limited time, a 29% discount. The Levoit Sprout Evaporative Humidifier
Also: I knew this robot vacuum was a winner just hours after testing it – here’s why
I tested the Levoit Sprout Smart Air Purifier, available for $190. Both are smart air purifiers, but they have features that set them apart for different use cases.
In my testing, I ended up relying on both. I set up the Levoit Sprout Evaporative Humidifier in my older kids’ rooms, which came at a great time because they were in the throes of a cold in the dead of dry winter conditions.

While most smart air purifiers give you insight into particulate matter (PM) in the air around the device, this one has five sensors to monitor seven air quality factors. The Levoit Sprout Smart Air Purifier can monitor PM (1.0, 2.5, and 10), TVOC, humidity, temperature, and carbon dioxide (CO2) levels in your or your kids’ room.
This smart air purifier flagged high CO2 levels in my three-year-old’s room, which we were completely unaware of. The CO2 levels in her room average over 1,100 ppm and can reach as high as 1,600 ppm while she is sleeping.
If you’re unfamiliar with acceptable CO2 levels in a home, they typically range between 400 and 800 ppm. Fair levels are 800 to 1,200 ppm, poor levels range between 1,200 and 1,800 ppm, and dangerous levels are above 1,800 ppm.

There’s also the option to buy a window fan that circulates outdoor air inside or removes stale air from the room.
I’ve also been running the central HVAC fan overnight to keep air entering the room and the Sprout Smart Air Purifier to clean this air and maintain airflow. These measures have lowered the overnight average by hundreds of ppm, bringing it down to around 800.

I have to preface this by saying that I’m a fan of data. I love getting a visual on everything related to my kids and home, which is why I love smart home devices. Because of this affinity for information, I’ve had each of my three kids wear a sleep monitor to bed from birth up to about the time when each one was two years old. It’s also partly why I have an air purifier in every room in my home (as well as an imminent risk for lung disease).
This gives the device the parameters it needs to adjust the humidifier’s intensity until it’s at the level I entered in the app.

I set up this device in the middle of a respiratory virus during winter. The Levoit Sprout Evaporative Humidifier has successfully maintained the humidity in the room, with me topping off the water almost every day, and worked as a night light for my little ones since I set it up.
ZDNET’s buying advice
The Levoit Sprout Evaporative Humidifier are perfect for kids, adults, and seniors. Each serves a different function, which I love because I like relying on the humidifier feature for illnesses and comfort and the thorough information I get from the air purifier.
