Easy to use

Simplicity is one of the major selling points of this humidifier. It has a very simple design and straight forward controls knobs that make controlling the unit simple. If you are a lover of the old analog controls, then this unit would go down well with you.

According to the manufacturers, the specification of this unit’s capacity is a 1-gallon water tank with an ability to run for 24 hours on the lowest setting and a mist output that is enough to humidify small-sized rooms.

Features to consider in choosing the best humidifier for hayfever

  • Capacity:

the capacity of a humidifier determines how well it would moisturize the air you breathe in. Your humidifier should be able to keep relative humidity at a safe level, therefore keeping your airways moisturize and alleviating the symptoms of hay fever. Units with poor moisture output would not effectively manage this.

  • Tank size/ runtime:

the size of a tank determines, to a large extent, the duration which it can run for. The larger the tank, the longer the unit would run, and the less frequently you would have to refill its tank. Although a runtime of above 15 hours is decent enough, we, however, recommend you aim for 20 hours and above.

  • Automatic mode:

in this mode, the humidifier balances humidity by itself. It measures relative humidity in the air and varies its speed to attain or reduce the amount of moisture, depending on your setting. Purchasing a unit with this feature would give you less stress and a better user experience.

  • Safety features:

these include automatic shutoff and child lock. The child lock only comes in handy when you have kids and pets at home. On the other hand, automatic shutoff protects you from the dangers of overheating and other related hazards.

  • Aromatherapy:

humidifiers that contain aromatherapy chambers gives better relief. It allows you to enjoy the health benefits of essential oils, as well as the primary mist that is released. You have double soothing benefits with aromatherapy; therefore, we recommend purchasing a unit that supports it.

Air purifier or humidifier for hayfever

Both a humidifier and air purifier are suitable for treating hay fever. While the humidifier generates moisture to help you feel better as you breathe, an air purifier removes allergens that cause hay fever from the air completely. They both play major roles and are equally as important when it comes to dealing with hay fever.

To be effective, they must be of good quality and used in the best way possible to create an ecosystem of clean atmospheric conditions.

Final Verdict – Best Humidifiers for Hayfever

Using a humidifier would help you ease hay fever symptoms like coughing and congestion and moisturize your airways. Humidifiers also make the air uninhabitable for a good number of allergens that are responsible for hay fever.

We recommend the Opolar product as the best humidifier for your hay fever. This unit has a large coverage area of 1000sqft and can produce up to 6 gallons of moisture per day. With this humidifier, be sure to always have relative humidity at a safe level at all times. It can also run for 20 hours before requiring a refill and comes with comfort features like automatic mode and shutoff, timer, and casters for easy mobility.

On the other hand, the HuPro premium ultrasonic humidifier is a product you can also purchase. It has 40 hours runtime before a refill and can humidify 500sqft of space. Other features include a timer, cool and warm mist option, aromatherapy, and automatic shutoff. It is very quiet and suitable for bedroom use.
