Air Purifier vs Humidifier: Which is Better for Allergies?

Knowing the difference between an air purifier vs humidifier can be the trick to combating your allergies.

Contrary to popular belief, the two terms are not interchangeable. They each offer specific functions and benefits, especially when it comes to your health.

Discover the difference between the two and which one you should choose to keep your allergies in check.

Air Purifier vs Humidifier: What’s the Difference?

The main difference between humidifiers and air purifiers is how they function.

Air purifiers are designed to cleanse the indoor air from pollutants. Dust, smoke, bacteria, and allergens like pollen and pet dander are removed from the air.

However, they do nothing to control the air’s humidity levels.

That’s what humidifiers are for. Humidifiers put moisture into the air, though they do nothing to clean the air.

When to Use an Air Purifier

Air purifiers are ideal for specific symptoms. Sneezing, rashes, respiratory problems or allergies can be reduced with an air purifier.

If you’re not sure about your air quality, you can have your air tested to find out exactly what’s floating around your home. However, if you would like to keep things simple, look for an air purifier with a built-in sensor to measure the levels of volatile organic compounds, or VOCs, in the air. These types of air purifiers simplify keeping your home’s air clean and safe.


When to Use a Humidifier

Dry air can cause discomfort, which is why many people use humidifiers in the winter. Humidifiers are great at combatting dry skin, chapped lips, and nosebleeds.

You can purchase external devices that measure a room’s humidity levels. When it drops below a certain amount, you can run a humidifier to get back to an optimal level.

However, there is such a thing as too much humidity. You won’t want to run a humidifier constantly. The right humidity level can help fight against mold growth and moisture problems.

The EPA recommends indoor air humidity should remain between 30-60%. The best humidifiers come with a built in humidistat. This allows them to automatically regulate how much moisture they add into the air.

Which One Wins the Allergy Battle?

When determining whether to use an air purifier vs humidifier, understand that both are essential for maintaining a healthy indoor environment.

Just as you wouldn’t want to drink dirty water, you also don’t want to inhale dirty air. Doing so can induce a variety of symptoms, such as sneezing, nosebleeds, and itchy or dry skin.

However, if you want to fend off allergens, the air purifier is the clear choice.

Keeping your air free of contaminants is key to reducing your allergy-related symptoms.

You might also benefit from having a humidifier to keep nasal passages moist.

You can purchase single-function air purifiers. Or, you could opt for a combination unit that controls both the air quality and humidity levels. Combination units are a great way to save space and money.

If your allergies are severe, you might want to opt for a built-in air purification system. These systems are installed professionally in your home’s HVAC system.

They work to maintain clean air throughout your home without having move portable units from room to room.
