If these symptoms persist despite you are doing all the right things — from dusting to sweeping and vacuuming — it's time to take a swing at technology. Specifically, air purifiers and humidifiers, which are the most commonly-used appliances for allergy relief.

Which one is right for you? Let's take a look.

What's the difference between an air purifier and humidifier?

While air purifiers trap pollen, dust and other allergens and recirculate cleaner air into the room, humidifiers release a mist of water or steam that helps you fight off allergy-related symptoms.

What are the advantages of an air purifier?

If your allergies are caused by dust, pollen, pet hair, etc., an air purifier is helpful because it filters out these allergens. They're also portable and don't take up a lot of space.

What are the disadvantages of an air purifier?

Allergens such as pollen and pet hair can fall to the floor or on furniture that's out of the air purifiers reach. Air purifiers also don't control humidity to prevent the growth of mold and mildew.

Also, you'll still need to reduce irritants in your house through sweeping, dusting, and vacuuming even if you have an air purifier.

What are the advantages of a humidifier?

Humidifiers are helpful in a hot, dry climate because they add water to indoor air while increasing the relative humidity. Breathing humidified air helps reduce symptoms such as nasal irritation and congestion.

What are the disadvantages of a humidifier?

It's important to maintain the proper balance between dry and moist when using a humidifier because some allergens thrive in a moist environment. If a humidifier is used in a humid environment, it may make allergy symptoms worse. Humidifiers also must be cleaned regularly to prevent mold growth.

There are four types of humidifiers:

Evaporative

Steam/mist

Ultrasonic

Impeller

So what's best for you? Air purifier or humidifier?

There are two main considerations when deciding whether an air purifier or humidifier will enable you to manage allergy symptoms. If the humidity in your home is lower than 40%, then a humidifier may be best for you.

If the humidity in your home is at recommended levels, then an air purifier is your best choice.
