Dry air dries out your respiratory tract aggravating allergy, sinus or asthma. Moreover, your skin, hair, eyes, mouth and the plants in the same environment also suffer the negative effects of dry air.
The dry air also makes allergens lighter and may end up in the air and into the respiratory system aggravating the allergies, sinusitis or asthma.
To determine if the air you are breathing in is dry or not, get a hygrometer and measure the humidity levels. The recommended level is 30-50%. Remember that too low or too humidity worsens allergies, sinus or asthma.
In case you do not have access to a hygrometer, note that when the air is dry, you might experience the following;
- A dry mouth, throat, and nosebleed when you wake up

Humidifiers add moisture into the air. Let us look into the types of humidifiers that are available on the market.
The whole house humidifier is connected to the central heating system. Great for home owners but for those who are renting, the single room humidifier is the option for you
Humidifiers are designed to disperse cool or warm mist. Either cool or warm mist is good for allergies though each type of humidifier has added benefits.
Warm mist also warms the air and thus good for cold environments. However take care that this unit is kept out of children’s reach to prevent burns as the water is boiled to produce the mist
Warm mist is great for upper respiratory tract infections as warm mist is better at decongesting the nose and throat.
The cool mist produces a cool mist which makes the room cooler and therefore good for hot environments. Cool mist humidifiers are also great for croup patients.
The cool mist humidifiers use different technology to produce mist as explained under;
The evaporative humidifiers have a filter that wicks the water up. A fan then blows the water into the air. This is the humidifier type that is most noisy.
The ultrasonic humidifiers use high frequency ultrasonic waves to turn water into particles which are easy to disperse in the air. It is “whisper quiet” and thus preferred by those who love sleeping in quiet environments. It is also good for office use. However they also produce white dust as the water is not filtered. Should you fall in love with the whisper quietness, choose one that allows you to insert demineralization cartridges or simply refill with distilled water.
The hybrid- the cool and warm humidifier
This type of humidifier allows you to enjoy the benefits of both warm and cool functionalities and thus more expensive!
As mentioned earlier, if you are already suffering from allergies, asthma or sinuses, you need to take special precaution when choosing a room humidifier. In this section, we will cover the special and general considerations.
White /gray dust
Read the best humidifier for sinus problems reviews and make note of the units that disperse dust. This dust happens to be mineral deposits that are dispersed together with the mist and may aggravate the allergy, asthma or sinus or even cause a flare up. Ultrasonic humidifiers are more often the culprits as most of them have no filters. The filter is meant to remove the minerals from the water before the mist is dispersed in the air.
You may be better off choosing an evaporative or steam humidifier (though noisier) or get an ultrasonic unit that has a filter. Alternatively you can also choose an ultrasonic unit that accepts demineralization cartridges in the tank.
Dust is what an allergy sufferer wants to keep away from. The filter is meant to ensure that no dust, pathogens and other contaminants is dispersed. Go through the best humidifier for allergies user reviews to confirm the manufacturer’s filter quality promise.
Easy to clean
You do not want to add an infection to your allergy by choosing a room humidifier that is not easily cleaned. A dirty unit is a good breeding ground for mold, bacterial and other disease causing micro-organisms and will also disperse the germs alongside the water and probably aggravate the allergy.
Your best humidifier for allergies should ideally have a larger tank opening. The various parts should be easily dismantled, cleaned and reassembled and possibly dishwater safe.
Essential oil/ Medical Vapor diffusion functionality
Look out for that room humidifier that can diffuse medical vapors or essential oils that help ease the allergies.
Each humidifier is designed to serve a certain size of space and will not be effective in a bigger space. Make note of ceiling height as high ceiling means more space and thus a more powerful humidifying unit.
Get that best humidifier for sinus problems, allergies or asthma which is easy to operate.
Apart from the energy bill which might be higher for warm mist humidifiers, consider the filter costs. How often do they need to be changed and how much do they cost?
Look out for the humidifier that gives you more hours of continuous mist.
Auto shut off when tank is empty
The best humidifier for asthma with this feature automatically shut off when the tank runs dry. Running the tank dry may burn out the motor faster as well as increase your energy bill for no good reason.
Some humidifiers for allergy allow you to adjust mist direction to your desired target.
