The Best Humidifier Options for Maintaining a Healthy Atmosphere
Whether you live in a hot and dry climate where the air conditioning runs most months of the year, or in a cold environment where the furnace dries out the air, a humidifier is a must-have for any household.
A high-quality humidifier helps create a healthier environment for your family by maintaining the ideal humidity level in your home. We have worked to bring you a list of the best humidifiers on the market.
Humidifiers allow moisture to infuse into the dry air of your home using cool ultrasonic mist or warm mist. They reduce allergies and cold symptoms and improve overall health for all household members.
Healthcare researchers now know that there is an ideal moisture level for health; a humidifier can help maintain that optimal level. See our verdict to know the best humidifiers, including the best models for the nursery, the whole house, cool mist, and warm mist.
1. What Is a Humidifier?
A humidifier is an electronic appliance that distributes water into the air to increase the humidity level of the environment. The best humidifiers are usually made of a reservoir that holds water, a pump to vaporize the water, and a power cord at a basic level.
From there, extra features are added to customize what you need. Some models have features such as filters, air direction vents, timers, essential oil diffusers, auto controls, and stylish shapes.
2. How Do Humidifiers Make the Home Environment Healthier?
A humidifier is an ally for a healthy home. Dry air leads to dry eyes, sinuses, and skin. All that dryness leads to extra irritation, which is only exacerbated if you have allergies or colds.
Humidifiers can minimize runny noses, congestions, dry throat, and coughing. They also keep houseplants happy, increasing the oxygen levels indoors, and are great for infants' sensitive, fresh nasal passages.
3. How Do Humidifiers Help With Allergies?
If you keep your humidifier clean or use a model which includes a filter system, the humidifier will reduce dust, pollen and other allergens from the air. This, combined with increasing moisture in the respiratory system, lends to fewer allergies.
The respiratory system is soothed and irritants are kept away. Be sure to clean your humidifier as instructed by the manufacturer regularly.
4. What Types of Humidifiers Are There?
There are many types of humidifiers, but the most common ones are warm mist, cool mist, vaporizers, and ultrasonic machines. All of the best humidifiers add moisture to the air, so which you choose is up to you.
However, do keep in mind that cool mist humidifiers are considered the safest to use around children and pets. Warm mist humidifiers can put out warm mist as hot at 104 degrees Fahrenheit, which may risk burns with small children.
5. What Is the “Right” Level of Humidity?
Chances are, you are looking for a humidifier because you want the air in your environment to be wetter. We support that plan.
However, there is a point when humidity levels are too high, and you should not run your humidifier nonstop unless it has auto humidity detection.
Experts recommend keeping indoor humidity levels between 40% and 60% to avoid encouraging the growth of mildew and mold, so if your humidifier does not monitor levels for you, consider a humidity monitor.
6. Who Benefits From a Humidifier?
A humidifier will improve the health of all living things in your home and most non-living things. Ideal humidity levels enhance the health of adults, the elderly, children, infants, and pets by reducing allergies and cold symptoms and improving skin health.
Houseplants benefit from proper humidity levels too; most houseplants are not meant to survive well in dry climates. Even wooden floors, cabinets, and specific musical instruments help from a humidifier.
7. When Should Humidifiers Be Used?
Long gone are the days when humidifiers were kept in the closet until grandma or the baby got sick. We now know that a humidifier benefits the health of all of us and can even prevent allergies.
We believe that running a humidifier is something that most homes should consider most days unless you are lucky enough to live in a semi-humid environment.
8. How Long Will the Best Humidifiers Last?
Most of the best humidifiers will come with a decent warranty from the manufacturer. Even so, once that warranty has run out, you can expect your humidifier to last for many years.
Provided you care for it the way the manufacturer recommends, use distilled water, clean and replace filters as suggested, you can count on the best humidifiers to last for many years of reliable use.
