Best Humidifier Allergies – The Best for Your Sneezing Glitches

Humidifiers have since long been known to aid in combatting the effects of breathing in dry air and give relief from symptoms of allergies. When the humidity levels are very low, the lower airways and nasal passages become irritated, which further aggravates any existing allergy symptoms. When humidity is also too high, allergens like mold, pollen, mites, and dust might also thrive and exacerbate the symptoms. This is the reason why balanced humidity levels are important for keeping any allergies at bay. If you are suffering from these allergies and hope to keep the ideal humidity at home, or anywhere for that case, this article will guide you to the best humidifier allergies. To business then!

Honeywell GermFree HCM-350 – Best Humidifier Allergies

The Honeywell HCM – 350 is a favorite among many buyers and the motivation for this is easy to see.

Usually, this means you have to possess two different appliances – a humidifier and a purifier. This machine from Honeywell does both, sort of like a 2-in-1 device. It humidifies the air and removes 99% of mold, bacteria, fungus, and other airborne irritants thus reducing the causes of allergic reactions. It is one powerful evaporative humidifier that can service areas of up to 500 square feet with much ease. The 2.3-gallon humidity output each day makes sure of this.

This model doesn’t even claim to have the cleansing power it has but tests have proven it is more than capable of just humidifying the air. It utilizes a patented UV technology that has amazing allergen-busting capabilities. The released air is purified as well as humidified. It is also very simple and safe to clean as all the parts that need cleaning are dishwasher safe. Additionally, this Honeywell is very quiet.

Unfortunately, the biggest downfall of this device is the lack of interactive features such as water indicators and automatic shut-off. Nonetheless, what it lacks in smart features, it compensates for in reliability, durability, and affordability.
