6 Best Humidifiers For Allergies And Asthma

best humidifiers for allergies
Choosing the best humidifiers for allergies and asthma is very beneficial to prevent the attacks and help you feel better.

When air is too dry, or low in humidity, breathing difficulties can develop. Or for those with existing breathing related issues such as allergies and asthma, low humidity conditions can aggravate the issue. Humidifiers can offer a great deal of relief to those who suffer from conditions like this.

In addition to breathing difficulties, dry air can also affect other parts of the body. Dry, sore and irritated eyes are one common problem. Also, skin irritations can develop which can include painful cracking and splitting or itchy and dry skin. A humidifier can help by adding moisture to the air which keeps humidity at a safe, healthy level.

Another way in which humidifiers can assist with health issues is during cold winters. If you live in a cold climate, it may result in very dry, low humidity conditions. These uncomfortably low humidity levels common in colder climates can cause many health-related problems.

A humidifier for allergies and asthma sufferers can also help with keeping your skin in good condition during the drier months. As such, using a humidifier is definitely worth considering if you suffer from any issues like this.

The Different Types of Humidifiers

Humidifiers come in different designs but generally fall into three unique categories. They are Warm Mist, Cool Mist, and Ultrasonic. Here is a detailed look at each different type.

Warm Mist Humidifier

Just as the name suggests, this type of humidifier produces a warm, soothing mist. This mist you can actually see and feel, and this is a good product for treating colds and flu.

Although the warm mist variety requires more frequent cleaning, they operate quietly. In fact, a warm mist humidifier is much quieter than the cool mist style.

However, the hot steam produced by this kind of humidifier can increase the temperature of a room. The mist may also be harmful if it makes direct contact with skin, particularly the facial area.

Cool Mist Humidifier

The way in which a cool mist humidifier works is that it traps minerals and impurities in a filter. Then a cool, invisible mist is evaporated into the air.

This style of evaporative humidifier is much easier to clean and keep clean. Plus, they are effective when used in warm climates as well as in large rooms or areas.

Cool mist humidifiers are louder in operation than warm mist varieties. Also, they need more maintenance which means frequent filter changes to prevent bacteria from developing.

Ultrasonic Humidifier

This type of humidifier uses a metal diaphragm which vibrates at an ultrasonic (very high) frequency. This creates droplets of water out of an onboard water tank that a fan sends into the air.

The ultrasonic style of humidifier is one of the more quiet types and the moisture it produces resembles a cool fog. Tap water tends to result in the formation of a white dust so distilled, bottled or filtered water works best.

In addition to being easy to keep clean and operate, this style also requires far less maintenance. They can also provide humidity control to quite larger areas.

The Different Sizes/Styles of Humidifiers

Room Humidifiers

The best humidifier for asthma and allergies can give you relief quickly and easily.

A room humidifier is a unit that is designed specifically to regulate the humidity in the space of a room or portion of a room. These humidifiers are generally smaller in size and portable.

Sizes range from small table-top designs up to and including large floor-mounted units. Typically any room humidifier is considered portable as it can be moved from one place to another.

Whole House Humidifier

There is a difference between whole house humidifiers and the type that can be joined as part of the HVAC system of a home. But they both provide large area coverage.

Because a whole house unit is so large, it is not really designed to be easily moved from one area of the home to another. However, with tanks in the 5-gallon range, refilling is less frequent.

With the size of this style of humidifier, cleaning will be required at least weekly. Also, filters and wicks will generally have to be replaced at least quarterly.

Furnace Humidifiers

Furnace humidifiers are permanent units. They are usually installed in large homes or commercial buildings along with a forced-air furnace.

Of the furnace humidifiers, there are different types that use forced-air. They include drum, disc wheel, by-pass flow-through, and steam. The names generally explain the type of technology used in providing the moisture that regulates humidity levels.
