Air Purifier Benefits and Advantages

1. Air Purifiers Eliminate Allergens

If you suffer from allergies, you’re not alone.

In fact, more than 50 million Americans alone experience various types of allergies throughout the year and are the 6th leading cause of chronic illness in the U.S.

Fortunately, air purifiers are designed to eliminate the particles that cause allergies to flare.

When a HEPA air purifier runs, it sucks the surrounding air into the machine and passes it through a series of filters.

These filters capture the allergen particles and push clean air back out the other side to re-enter into the room for you to breathe.

Some air purifiers don’t use filters but rather a process called “ionization” to clean the air. This method pulls allergens out of the airt through the use of microscopic ions.

Thes ions cause allergens to cling to surrounding surfaces and the floor.

While an ionizer air purifier doesn’t technically trap allergens inside a filter, it does keep those particles magnetized to surrounding surfaces and out of the air you breathe.

2. Air Purifiers Reduce Dust and Dust Mites

Just as air purifiers can remove airborne allergens, these machines are also capable of reducing dust particles too.

The same method applies for air purifiers as mentioned in the previous point.

The machine can either trap and collect the dust particles inside a HEPA filter or use ionization to stick them to surrounding surfaces.

Either way, an air purifier can keep the dust out of the air you breathe and prevent it from entering your lungs, eyes and throat.

If you have a dust allergy, investing in a HEPA air purifier is a good thing to do because it can reduce your exposure to this substance.

Additionally, the longer a HEPA air purifier runs, the cleaner your home becomes.

If you want to keep your house in tip-top shape without having to dust or vacuum as often, an air purifier can definitely help with this task since it can collect a majority of the dust particles for you.

3. Air Purifiers Cut Down on Pet Dander and Hair

Do you have cats, dogs or other pets living indoors that shed an unbelievable amount of pet dander or hair?

If so, you’re in luck because some air purifiers have been designed to tackle those specific problems.

Air purifiers built for pet owners work by drawing air into the machine and trapping the airborne pet dander particles that fill up your home and cause pet related allergies.

These machines are also good at trapping pet hair that otherwise would collect on your floors and furniture.

If you have cats dogs or other animals living in the home, you should consider using an air purifier to help keep your home cleaner and free of pet dander and hair.

These machines also work well for cutting down on pet odors too.

4. Air Purifiers Trap Smoke

Are you a smoker?

Do you live with one?

Or is your house located in an area that’s prone to wildfires?

If you answered yes to any of those questions, you’ll be happy to know that an air purifier can help with all of those issues and more.

Air purifiers that use an activated carbon filter do an excellent job of stripping smoke and its odor out of the air.

If you or someone in your household smokes tobacco, these machines can dramatically improve the quality of air indoors by reducing visible smoke and the odor.

This rings true for both cigarettes and cigars.

If you’ve ever been to a cigar shop, you’ll likely notice that there’s a portable air purifier on site or the HVAC system has been outfitted with a dedicate air filtration system.

That’s why these locations don’t wreak of tobacco odor as much as you would expect.

If your home is situated in or near a wildfire area, you’re in luck too, because air purifiers that use a HEPA filter can reduce your exposure to the visible particles of smoke and an activated carbon filter can lower the odors.

If you use a wood burning stove or fireplace, you can reap the same air purifier benefits.

5. Air Purifiers Reduce Odors

We touched on this air purifier advantage in the last few points, but just to sum it up here, air purifiers are excellent at reducing odors of all types.

Not just from smoke.

An air purifier is a great machine to have indoors if you want to cut down on smells that come from pets, cooking, diaper pails, paints, and other common household odor sources.

If something produces an odor and the air purifier has the right filter to handle it, you can rest assured that the smells will go away or at the very least be much less prominent than they were before.

6. Air Purifiers Lower Volatile Organic Compounds

Volatile Organic Compounds or VOCs are chemical vapors that are emitted in the air by a number of things. The most common sources of VOCs include:

  • Building materials
  • Carpeting
  • Paints, varnishes and glues
  • Gasoline
  • Cleaning agents
  • Air fresheners
  • Furniture
  • Plastics

Many household products like carpeting and furniture contain materials that include VOCs and there’s nothing you can do to eliminate them.

Over time, these VOCs go through a process called “off gassing” where the chemical vapors leak out into the air.

Eventually, enough off gassing has taken place that the materials are not dangerous to you healthy anymore.

Fortunately, air purifiers can remove VOCs from the air before they have a chance to get inside your lungs, eyes or throat.

If you’re not fully conscious about the levels of VOCs in the products or chemicals you use in your home, an air purifier is a wise investment for your overall health.

7. Air Purifiers Capture Mold Spores

Inhaling mold is known for causing all sorts of health issues such as:

  • Coughing
  • Sneezing
  • Stuffy nose
  • Itchy eyes and skin
  • Nosebleeds
  • Tightness of the chest

At its worst, mold can cause severe cases of inflammatory reactions in the sinuses and lungs such as:

  • Asthma
  • Allergic fungal sinusitis
  • Allergic bronchopulmonary aspergillosis
  • Hypersensitivity pneumonitis

One of the great benefits of air purifiers is that they can reduce your exposure to mold spores by acting as a first line of defense against these particles.

As the air purifier runs, it can pull mold spores out of the air and trap them inside a HEPA filter. That way you stay protected from the effects of exposure.

8. Air Purifiers Protect You from Outdoor Pollution

Depending on where you live, you may hear a lot of talk about ozone, automobile and factory pollution on your local news.

The American Lung Association keeps a current list of the most polluted cities by ozone, year-round particle pollution, and short-term particle pollution.

One of the most talked about types of pollution is PM2.5 which refers to atmospheric particulate matter (PM) that have a diameter of less than 2.5 micrometers.

PM2.5 can get buried deep inside your lungs and cause all sorts of heart, respiratory, and lung disease as well as cancer.

What’s worse is that many outdoor pollutants can easily be trapped inside your home each time you open a door or window and then shut it.

And if you live in a city, your exposure to PM2.5 and other pollution is much higher because there is so much more of it.

Clearly, the benefits of using an air purifier are self-evident when you live in a highly polluted area.

So, consider investing in one if you are near the city center.

9. Air Purifiers Enhance Mood Levels

Can an air purifier really create positive vibes?

That’s what some research indicates.

According to a Columbia University study where people with winter and chronic depression showed that negative ion generators could relieve depression as much as antidepressants.

Appropriate doses still need to be sorted out but the good news is that there are no side effects of using an air ionizer as there are with medications.

It’s also been discovered that exposure to negative ions also increases the flow of oxygen to the brain which can produce higher alertness, decreased drowsiness, and more mental energy.

If you want to find out of negative ions can have a similar impact on your own health, consider getting an ionic air purifier or a HEPA air purifier that includes an optional ionizer. Then, turn the machine on and let it operate.

If after a few days you start to see an enhancement in your mood or an overall feeling of mental alertness, you may have just found your ticket to paradise.

10. Air Purifiers Reduce Carbon Dioxide

The process of inhaling oxygen and exhaling carbon dioxide is natural and usually not much of a concern.

However, when you’re confined to a small space or there are too many people inside a room, the amount of carbon dioxide can exceed the level of what’s considered safe.

Consuming too much carbon dioxide is known to cause:

  • Shortness of breath
  • Headaches
  • Dizziness
  • Sweating
  • Weakness
  • Loss of mental abilities
  • Unconsciousness
  • Elevated blood pressure
  • Increased heart rate
  • Nausea
  • Lung disease
  • Death

Having an air purifier that uses a HEPA filter can help lower your risk of breathing in too much carbon dioxide by eliminating it from the air.


As you can see, there are many benefits of air purifiers.

Not only can they help you keep a cleaner and more fresher smelling home, but they also reduce your exposure to a number of potentially life-threatening pollutants.

The advantages of air purifiers far outweigh their costs and if you weren’t sure if you should invest in one or not, hopefully, the information on this page has helped you make up your mind.
