How We Decided

To help narrow down to the above top products, we tested out humidifiers for mist distance, making sure they would easily service a standard sized living area, and maximum water output, with each product passing a threshold of 150 ml per hour and several pumping out 300 ml per hour.

Additionally, we looked at the tank size, choosing products with large water tanks, at least 1.8 liters and as much as four liters, to ensure a lengthy period of continuous use before needing a refill, as much as 60 hours in our top pick. We also wanted to make sure these products are safe for an infant’s nursery, with no small parts and, for the most part, being manufactured without the use of controversial ingredients, such as BPA.

Finally, we chose a few products with dual functionalities, acting as both humidifier and oil diffuser, for the use of therapeutic oils. Several oil variants, such as lavender and dill, are safe for babies. For peace of mind, each product contains at least a one year warranty, with one product boasting a two year warranty.

Baby Humidifier Buying Guide

The Most Important Features to Consider

  1. Water Tank Size and Maximum Output
    Humidifiers come in a variety of sizes, with different water tanks. While our top pick will get you 60 hours of continuous use, thanks to its four liter tank, any of the above products will run through the night, at least ten hours. Additionally, you may want to take a look at the humidifier’s maximum output, which can help humidify large rooms quickly. Our top pick boasts a maximum output of 300 ml per hour but we found that anything in the 100 ml per hour range was suitable for most rooms.
  2. Baby Friendly
    Some humidifiers boast some baby-friendly functionalities, such as soft, multi-color night lights, which can be a good source of light during night time breast feedings. Additionally, most of the above products are certified to be BPA free. BPA is an industrial-grade chemical that has been used in the manufacture of products since the 1960s and has been shown to interfere with the production of human hormones.
  3. Oil Diffusion
    The diffusion of essential oils has become quite popular in recent years, as seen in the many humidifiers coming to market that offer dual functionality. Oil diffusion allows for the disbursement of various aromas throughout your room, for therapeutic reasons, such as lavender and mint.
