It’s still midwinter, and while the weather remains chilly, you’re probably spending most of your time indoors. Staying warm is important, but so is breathing in fresh air that isn’t stale or dry. Air purifiers can help with the first requirement, and humidifiers can help with the second one.

Humidifiers are a great way to rid your home of uncomfortably dry air and can make a world of difference to your respiratory health. Right now at Best Buy, you can get the Kyvol HD5 ultrasonic humidifier for just $45 (save $45).

This humidifier comes with a large capacity water tank and sprays out a soothing mist. It can humidify rooms that are up to 380 square feet, making it ideal for offices, nurseries and plant environments. When sleep mode turns on, the humidifier will turn off its main water tank light and turn on its night light while lowering its mist and noise levels.

You can adjust the night-light to a warm light and create a cozy atmosphere before you go to sleep. The humidifier also has an auto shut-off system that turns the unit off when it runs out of water, protecting itself from damage. You can also set up a timer for this incredibly small and compact humidifier.
