This is a great pick if you’re looking for a multi-functional device that can purify the air, provide soothing sounds, and act as a nightlight.


  • Multiple functions in one device
  • Adjustable fan speeds
  • Colour-changing nightlight


  • Nightlight colors are cool-toned

This Frida Baby 3-in-1 Baby Sound Machine is perfect if you need a sound machine and an air purifier for your child’s room. Its sleek design and compact size make it an excellent addition to any nursery without taking up much space. The HEPA filter is efficient at removing smoke, odors, and pollution from the air, ensuring your baby breathes clean air.

The adjustable fan speeds and auto-off timer can help you set it up just right for your child’s needs. Meanwhile, the nightlight comes in four colors, which creates a soothing environment for bedtime. However, some parents might prefer warm-toned colors over the blue and green options available.

While the sound machine’s white noise feature is beneficial, some users found it lacked variety in sounds. The air filter’s 90-day lifespan could also be seen as a downside since replacements are necessary relatively often. Nevertheless, the combination of features makes this product an ideal choice for a multi-functional device in your baby’s room.
