If you want a quality, warm mist humidifier then you will have to know some of its basics when it comes to use and maintenance. You also have to keep some buying tips and guides in place to ensure you get a proper functional item that can take you some years without any problem.

Here are some of the top buying guides to help you narrow your preferred choice.

  • Room size and square feet covered– Before you buy any warm mist humidifier for a small or big room, you should consider the square feet covered in order to make the right purchase. You should also consider your ceiling height and factor in some extra square foot coverage for effective humidification
  • Filter or filter-less– This often depends on how much you cherish and prefer filtered air. Some warm mist humidifiers often come with washable or replaceable filters. Therefore, it all boils down to how much you are willing to spend on extra maintenance costs. However, if you happen to be filtering your air some other way then there is no need to buy a humidifier with filter features
  • Humidistat– This is very important as it can auto-shut the humidifier when it reaches a certain pre-set humidity level. However, you can always buy a separate hygrometer that can help it monitor the humidity level
  • Safety- Since warm mist humidifiers often, boil water to emit vaporized steam safety is always a top priority. You have to ensure it does not leak and has no issues of constantly falling over. Moreover, try to place it somewhere safe and out of children’s reach. Although every manufacturer will guarantee safety, rely on customer reviews for this piece of information
  • Energy efficient– Warm mist humidifiers often need energy to run. So, ensure you buy one that is efficient when it comes to energy use. Those that are energy efficient are often marked with an energy star logo. But if it does not have the logo then it can be hard to determine its level of energy consumption
  • Ease of maintenance and cleaning– A warm mist humidifier often needs to be cleaned every now and then to prevent any residue build-up on its heating elements. Therefore, you can opt for one that is easier to clean. The cleaner it is the better it will function and last for a few years
  • Ease of use– The easier it is to use, the more it will last. So, pick the best humidifier you know you can operate and troubleshoot whenever needed
  • Purpose– You should also consider its main purpose to your home before buying it. This is because warm mist humidifiers for dry skin and air often require multiple steam settings while those reserved for people with weak immune system tend to have germ-free features
