Considerations for choosing the best humidifiers for colds

  • Room size capacity:

The most paramount feature to consider in a product, before settling with it as the best option for your home in cold seasons.

Simply, humidifiers are designed with a limit on the sizes of rooms of which it can serve. Most times it is indicated by the manufacturer, and we recommend you look out for it, compared with your home size before purchase. Get a unit that can serve your space correctly.

  • Rotatable nozzle:

This feature isn’t a must option, but it would really come in handy when you intend humidifying specific areas of the home that doesn’t seem to get enough moisture. Being rotatable most times in 360 direction, it allows you to choose precise directions on which the mist would follow, to your taste.

  • Mist output capacity:

The rate at which a humidifier is able to generate mist is almost directly related to its ability to affect the humidity in your atmosphere. In essence, a device with a higher mist output rate is sure to increase humidity in lesser time than one with a low rate.

  • Automatic features:

These include a timer, auto mode, humidistat, and an LED display. They all work in hand to alleviate most inconveniences that result from users interacting with the device. Purchasing one with all these is sure to make your life a whole lot easier.

  • Easy to fill and clean:

In the cold season, the humidity level is on a default low. Therefore you can expect your humidifier almost to run all day, and if it can only hold little water, then be sure to get pissed by constant refills every now and then.

As a result of the expected common runtime, it would get dirty faster, hence requiring more frequent cleaning. Get one that wouldn’t make that tough for you.
