11 Best Rated Warm Mist Humidifiers for Sinus Congestion

D o nasal congestion, chapped lips or asthma episodes sound familiar? If you are often struggling with these symptoms, the humidity level in your house may be too low. A warm mist humidifier uses water to produce warm vapors, thus increasing the thermal comfort in the place it is used.

Humidifiers for large rooms and warm mist systems are perfect for people suffering from allergies as they boil the water, preventing germs and mold spores to dissipate in the air through the mist. Furthermore, some models include special compartments that allow you to add aromas or medical inhalants for a more efficient treatment.

The aromatherapy some of these products lets you benefit from helps reduce stress levels and improve sleep quality. Something you likely didn’t know is that stress levels are related to indoor humidity. A 2020 study conducted on office workers in four different buildings with distinct humidity levels showed that working in an environment where humidity is within normal parameters helps reduce stress levels by up to 25%. Dry air conditions, on the other hand, were found to negatively affect stress levels the most. So, aside from helping with sinus congestion, keeping colds and flu at bay, the presence of a humidifier indoors during the dry months of the year even helps you manage stress better.

During those cold months when air humidity levels drop and you seek the soothing effect of a humidifier, a warm mist unit like the products reviewed here is what you need. Since the mist it releases feels warm, a cozier indoor environment is inevitably produced. So, if you want to enjoy thermal comfort while benefiting from proper humidity to keep stress and colds at bay, get yourself one of the following humidifiers and all of your problems will be solved.

If you’re looking for a solution to keep your baby from developing nasal congestion this winter, you should look into specialty humidifiers for baby room.

Aprilaire 800 Performance Ratings – Tester’s Feedback
  • Covers the promised size area: Score 10/10
  • Humidity level stabilization speed: Score 10/10
  • Ease of installation: Score 9.8/10
  • Ease of use: Score 10/10
We had to put our skills to the test a bit to install the Aprilaire 800, we must admit. But none of us are that experienced or the handy type either, so since it took two of us less than three hours to finish setting the humidifier up, you shouldn’t have any problems either. Just follow the instructions in the manual closely and you won’t have any problem. The digital control panel makes operating the humidifier as intuitive as possible, we had no trouble figuring out the setup whatsoever. When it comes to performance, we tested in a similarly sized area to the one recommended by the manufacturer. It did solve low moisture problems as promised throughout the whole house, so we had to give the Aprilaire the highest score for performance and coverage.

Frequently Asked Questions



Why do I need a humidifier?
Many cold symptoms, itchy skin, dry eyes, allergies, or respiratory conditions are either provoked or intensified by low humidity. A humidifier increases the moisture in the air by releasing water vapors or extra-fine drops, thus creating a more comfortable environment.

What is the ideal humidity level?
Although humidity is important for your health and comfort, it should be kept between 30% and 50%. If the moisture in the air overcomes 50%, there is a high chance that mold, mildew, bacteria, and other dangerous pests breed and grow in your house. On the other hand, if it drops below 30%, flu viruses will be the ones invading and ruining the peace of your home.

What size humidifier do I need?
The main criteria is the size of the space you are looking to cover. The larger the space is, the bigger should the humidifier be. To be sure, you can check the product’s specification list, as the area of coverage is often included there.

Is cool mist better than warm mist?
When it comes to efficiency, there’s no notable difference between a cool mist and a warm mist humidifier. They both increase humidity, reducing the discomfort in the room. However, if you have kids, a cool-mist device is recommended, as the hot water in the warm-mist can spill and cause accidents.

How often should a humidifier be cleaned?
The ground rule is that you should never leave water in the tank and use it again the next day. The tank should be emptied when the humidifier has done its job and dried with a towel so the moist surface doesn’t become a breeding ground for bacteria. Moreover, if it’s used daily, it should go through a thorough cleaning at least once a week.

Should windows be closed when using a humidifier?
Keeping the windows closed while using a humidifier can cause the humidity to rise abruptly, reaching values that are dangerous for your health. It’s best to place it in a well-ventilated space, where the windows and doors can be kept open.

Can you put tap water in a humidifier?
Humidifiers can run on tap water. However, it is not recommended. Tap water contains plenty of minerals that tend to spread into the air with the mist. Moreover, in time, they deposit on the humidifier’s internal components, reducing their performance and lifespan.



Conclusion

For the clean, odor-free mist, it includes a microporous cartridge that catches microorganisms, thus increasing the safety of your home. For the best results, it is recommended to change the filter every 4 to 6 months.

When it comes to choosing the best warm mist humidifier, some specifications are worth to be considered. Depending on the space you are going to use this appliance, you may want to pay attention to its mist output, area of coverage, maximum run period, or integrated smart functions.
