How to Choose the Best Warm Mist Humidifiers
As you can see, there are many varieties of warm mist humidifiers available today, and you will need to consider a couple of things in order to make a smart purchase.
We discussed them at the beginning of this review, and for the most part, these units retailed for under $50.00, so you should be able to find a unit in your price range.
How Large an Area the Unit Can Treat
Most of these units that disperse warm air are for small to medium room sizes, you can find a couple in the high-end price range that says they can do a large room or small home, but they can get pricey.
Warm Mist Over Cool Mist
This is somewhat of a personal choice, and many choose the warm mist for the purification of the steam through the heating process. New technology has made it easier to get humidity into your home using cool mist, but it may make the units harder to clean and not as sanitary.
Many cool mist units also cannot provide the same relief from congestion as they don’t allow for the use of eucalyptus or other additives.
Why Do You Want or Need the Unit?
Is it for everyday use or just for the cold you may have? The answer to this question may help you to decide your financial budget for the unit. It may pay-off, in the long run, to purchase a more expensive unit if you intend to use it every day. From research, it seems that all of these units have a very limited lifetime just due to the nature of the unit. Water and electricity equal corrosion so keep that in mind also.
Your health and breathing may benefit from the addition of a warm mist humidifier to your home, and this may also help with sleeping issues as well. Your need or want for a warm mist humidifier may simply be that your skin is dry, or you experience static electricity in your home.
Whatever the reason you can find the unit you are looking for with some research and take a closer look at the ones above any of these should be able to help your situation.
