• Tank Capacity: 1.45 gal.
• Runtime: 40 hrs.
• Aromatherapy Option: Yes

Top of the list is TTLife’s humidifier and it takes the best overall spot because it offers both warm and cool mist humidification. This makes it very practical because you can use it all year round, whether hot during summer or cold in the winter.

Additionally, the warm mist reduces bacteria and pathogens while also preventing the growth of microorganisms in the water.

These two veils of mist are shot out by dual 360º rotating nozzles, which enables you to direct the moisture to different parts of the room for uniform humidification.

The output is controlled via 3 levels, with the lowest one producing 100 and 200 mL/H of cool and warm mist respectively. The medium setting gives you 200 and 300 mL/H while the high gives you 300 and 550 mL/H of cool and warm mist respectively.

With these settings, the humidifier can cover rooms of up to 750 sq. ft. while its 1.45-gal tank can last up to 40 hrs. without refilling. That said, the cool mist is provided by a quiet ultrasonic system while a built-in ionic generator purifies the air and has an ionic filter softens hard water.

Other features include 3 smart modes (constant-humidify, auto mode, and sleep mode), an aroma box, a soft-light touch LED screen plus remote control, a 12-hour timer, a built-in humidistat, and child safety lock. The only problem is that the unit has no night light for a dreamy ambiance.

How to Buy the Best Humidifier for Sinus Problem

1. Type of Humidifier

Cool Mist

There are two types of cool mist humidifiers. First is the evaporative type and this incorporates the use of an internal wick filter to absorb water from the tank while a fan blows air through it. This evaporates the water to create a fine mist. The biggest problem with this is its noise output.

The second type is the ultrasonic cool mist humidifier, which is very popular. It uses a metal diaphragm vibrating at an ultrasonic frequency to split the water into very tiny droplets, which are then blown out as mist. It runs very quietly and is, therefore, better than the evaporative type.

Because the produced mist is cool, this type is better to use during the hot summer weather.

Warm Mist

Warm mist humidifiers or vaporizers use a heating element to boil the water and then release the steam as mist. Because of this, they kill bacteria and other microorganisms in the water, which makes them more hygienic and healthier.

Additionally, they are quieter because they don’t require a fan to blow out the steam. However, they consume more electricity and usually form mineral deposits after the water has boiled out. To avoid this, you should use distilled water.

That said, the warm mist is ideal for the cold winter weather.

Buying Guide: If you want a humidifier for the cold winter months, buy a warm mist humidifier. For the summer months, a cool-mist unit is best.

However, some can produce warm and cool mist, which makes them suitable for use during all seasons. These are highly recommended and a great example is the TTLife Humidifier.

2. Coverage

Measured in sq. ft., a humidifier’s coverage determines the room size that it can humidify to the required humidity level. That said, you need to measure your room’s size before buying the unit.

Those with a wide coverage like Aprilaire’s 400 (4000 sq. ft.) are ideal for the whole house while those with a small coverage, like Pure Enrichment’s PEHUMIDIF, are ideal for small spaces such as baby rooms.

3. Water Tank Capacity

The larger the water tank, the better because this means a longer runtime without any interruptions. Some humidifiers even have connections to the water supply and this means no refilling is ever required. This is very convenient and is found in Aprilaire’s 400.

4. Aromatherapy Option

Apart from improving the air quality, adding on a sweet smell is a big plus and therefore, those humidifiers with an aroma box are highly recommended.

5. Maintenance

Filter-free humidifiers are very easy to maintain but this might transfer impurities to the heating membrane or metal diaphragm in warm or cool mist units respectively.

On the other hand, a filtered humidifier requires some maintenance work in the form of replacing the filter every now-and-then. The ideal solution would be to have a permanent filter, which does not need replacements.

This can be found in Air Innovations’ MH-701BA-PLAT, which has a permanent ceramic filter that is very easy to maintain. Only some cleaning is required once in a while.

7. Noise Level

This is an important factor to consider especially if you’ll be running the humidifier as you sleep. That said, ultrasonic cool mist and warm mist units operate at the lowest noise levels and you should only consider buying these types.

Conclusion

To recap, the two main types of humidifiers are cool and warm mist. TTLife’s Humidifier takes the overall best humidifier for sinus problems spot because it combines both types in one, enabling you to breathe comfortably during the summer or winter weather.

However, if you would like a unit to humidify the whole house, be sure to check out Aprilaire’s 400. Though expensive, this has a 4000 sq. ft. coverage, which is quite large. If you are on a tight budget though, the Vicks VUL520W is the most affordable option to buy.
