Some Interesting Statistics on Allergies

  • Did you know that approximately 50 million Americans and 100 million Europeans suffer from allergic rhinitis (or hay fever)? And, this number is steadily increasing each year?
  • Were you also aware that doctor offices and emergency rooms receive more than 13.4 million visits on an annual basis due to allergy issues?
  • How about that the estimated cost of allergies on the health care system in the United States alone is upwards of 18 billion dollars?
  • Or, that pollen season has increased an additional four weeks per year due to global warming?

When you read statistics like these, it may seem hopeless to try and do anything about your allergy symptoms.

With pollen and other allergens causing such strain on the world’s health and health care system, you may think that constant suffering is inevitable.

But, there is a simple solution.

Fortunately, this rampant rise in global allergy sufferers has propelled the development of air purification technology.

Now, you can find specialized HEPA air purifiers for allergies that explicitly target those allergens.

And by investing in a device like this, you can enjoy an allergen-free home that not only leaves you feeling healthy, but costs a fraction of the price of taking long-term medication.

What to Look for in the Best Allergy Air Purifier

Now that you know air purifiers are a good investment for allergy sufferers, how do you go about finding the best one?

Well, something you’ll quickly discover when looking for an air purifier for allergies is that not all products are created the same.

In fact, there are several different types of technologies that manufacturers use to outfit their devices to clean the air.

When it comes to finding the best allergy air purifier, you really need to look for certain key features. Not doing so may cause you to end up buying a product that doesn’t work for your particular situation and won’t give you much (if any) allergy relief.

The two main features you want include:

  • A dedicated pre-filter
  • A True HEPA filter

A dedicated pre-filter is a must-have because it offers two major benefits:

  • It traps larger allergens from pollen and dust.
  • It prolongs the life of the True HEPA filter, so it can do its job more effectively at capturing microscopic allergens.

When looking at air purifiers for allergies, you’ll want a device that has a separate, dedicated pre-filter that can be washed and reused. That way you can keep your cost of ownership down by protecting the True HEPA filter from large particles.

The pre-filter is the first line of defense on air purifiers and prevents the True HEPA filter from getting clogged up too fast. This allows the True HEPA filter to capture the ultra fine particles that irritate your allergies.

A True HEPA filter is also essential for these two reasons:

  • It captures the tiniest allergy particles that cause your symptoms to flare such as microscopic pollen, dust, pet dander, mold spores, etc.
  • It traps and locks allergens inside and doesn’t allow to be released back into the air.

No other type of air purifying filter can capture particles as small as a True HEPA filter, making this feature crucial for anyone who suffers from allergies.

In fact, True HEPA air purifiers can remove allergens as small as 0.3 microns.

To help you visualize that size, a human hair is 2-3 microns which is more than 600 times larger than the smallest allergy particle.

Another powerful aspect of this a True HEPA filter is that once the particles are trapped, they never get released back into the air. This means that after the air purifier has had enough time to exchange all of the air within a room, it becomes allergen-free and stays that way.

Note: You may come across cheaper air purifying products on the market called “ionic air purifiers” or “ionizers” that claim they can help with allergies. While their lower cost may entice you, these devices don’t actually trap allergen particles in a filter. Instead, they knock particles out of the air and cause them to fall onto surrounding surfaces. This means the allergens still reside in the room and will require consistent vacuuming in order to fully get rid of them from the room. So, stick with a True HEPA air purifier for your allergy concerns.

What is the Best Air Purifier for Allergies?

Now that you know what the top features are to look for in an air purifier for allergies, you’ll understand why the three products listed below are the best HEPA air purifiers for allergies you can get.

These three devices continue to top the charts with customer reviews and include the most important features necessary to help with allergy symptoms.

If you were to ask an allergist/immunologist what they recommend as the best air purifier for allergies, 9 times out of 10 he or she would recommend a Honeywell product.

And the one device that continues to outrank all others for allergies is this Honeywell HPA300.

What makes this product so special is that it meets strict guidelines set by the Association of Home Appliance Manufacturers (AHAM) and delivers a Clean Air Delivery Rate (CADR) performance rating of 300, which is unbelievable.

This air purifier achieves that high rating by using an odor-reducing pre-filter and True HEPA filter to trap all types and sizes of allergens.

This top rated HEPA air purifier for allergies also has an Air Changes Per Hour (ACH) rating of 5X. This means it can clean the air five times per hour in a room up to 465 square feet (roughly 21′ x 22′). That’s exactly what you want out of the best allergy air purifier for large rooms in your home.

At an extremely affordable price (compared to most other options) this is the best allergen air purifier you can get.

Consider the Honeywell HPA200 to be the little brother to our #1 recommendation.

It’s practically identical to the HPA300 listed above but is made for someone who doesn’t need to purify a large space (i.e. bedroom, home office, or spare room).

It boasts a 200 CADR rating and can handle a room size up to 310 square feet (roughly 17′ x 18′).

For around $65 cheaper, this is a great buy for anyone who wants the best HEPA filter air purifier without spending a lot of money.

Now, if you’re looking for an allergy air purifier that can handle a very large space (i.e. living room, basement, or big bedroom) or you just want a device that’s more customizable, then you’ll love this product.

It has some of the largest coverage available and can handle large spaces up to 1,100 sq. ft. (roughly 30′ x 36′).

In addition to offering a pre-filter for capturing the biggest allergens and a True HEPA filter for trapping the finest particles down to 0.3 microns, you also get the pleasure of customizing the HEPA filter to further meet your needs.

You have the choice between:

  • HEPA-Pure which is made specifically for allergies
  • HEPA-Silver which has additional layers of protection for asthma
  • HEPA-FreshPlus which helps to cut down on smoke and airborne chemicals
  • HEPA-OdorCell which has molecular conversion powder to reduce pet and baby odors

Additionally, you can customize the front panel to suit your individual taste and styles—choose between 14 colors and designs including white, blue, brushed bronze, brushed stainless, black, rosewood, natural maple, and more.

Like the HPA300 listed above, this one of the best air purifiers with HEPA filter is that it has a 300 CADR rating which is exactly what an allergy sufferer needs.

However, the only downside to this machine is that it can only exchange the air 2X per hour in a room up to 1,100 sq. ft. But, if you choose to place it in a room that’s smaller than that size, the air exchange rate will go up.

Overall, this is a great air purifier for allergy sufferers who want customization and need to cover large areas in the home.

More About CADR and ACH Ratings

In our reviews above, we mentioned two important concepts for each product:

  • Clean Air Delivery Rate (CADR)
  • Air Changes Per Hour (ACH)

The reason we pointed those ratings out to you is because they’re important for anyone who suffers from allergies.

CADR Explained

The CADR is an independent standard for measuring a filter’s efficacy that’s assigned by the Association of Home Appliance Manufacturers (AHAM).

The CADR rating indicates how well an air purifier is at removing smoke, pollen, and dust particles. The higher the CADR number is for each type of pollutant, the faster the air purifier can filter it.

CADR is broken down into three scores:

  • Smoke (10-450 CADR)
  • Dust (10-400 CADR)
  • Pollen (25-450 CADR)

Our number one air purifier review for allergies (Honeywell HPA300) has a CADR rating of 300 Smoke/320 Dust/300 Pollen.

Our number two recommendation (Honeywell HPA200) has a CADR rating of 200 Smoke/190 Dust/180 Pollen.

Our number three option (Alen BreatheSmart) has a CADR rating of 300 Smoke/300 Dust/300 Pollen.

ACH Explained

The ACH rating tells you how many times an air purifier can fully exchange the air within a certain size room.

For example, an air purifier that’s rated to handle 500 square feet and has an ACH rating of 5x means that the full volume of air in that size room can be exchanged five times every hour.

When you’re comparing air purifiers with the same room size coverage (square footage), the ACH number is important because it can quickly inform you as to which product does a more thorough job at cleaning the air.

Clearly, a 3x ACH is worse than a 5x ACH and a 6x ACH is better than the 5X ACH.

Just remember that the ACH rating is related to the specified square footage (sq. ft.) coverage for the air purifier. Therefore, if you place the air purifier in a room that’s smaller than the maximum size it can handle, the ACH rating goes up. If you place the unit in a larger room than it’s intended, the ACH rating goes down.

Our number one recommendation above (Honeywell HPA300) has a 5X ACH for 465 sq. ft.

Our number two suggestion (Honeywell HPA200) has a 5X ACH for 310 sq. ft.

Our number three review (Alen BreatheSmart) has a 2X ACH for 1,100 sq. ft. and 4X ACH for 550 sq. ft.

Benefits of Owning an Air Purifier

Owning an air purifier when you have allergy sensitivities is an easy way to improve your daily health. It’s also the most efficient and hands-free way to protect your home from allergen particle invaders.

Most people who don’t have an air purifier tend to rely on over-the-counter or prescription medications to help treat their allergies. While these solutions may help to treat the symptoms, the biggest problem is that you have to continue with these treatments in order to get relief.

Additionally, the cost of medications continues to rise every year and this extra expense is a real burden on a lot of people.

By adding an air purifier to your home, you’ll have a device that’s dedicated to stripping the air of the harmful airborne particles that irritate your allergies. Once these contaminants are gone and kept at bay, you’ll find that you may not even need to take allergy medications anymore (or at a much lower dosage)–saving you a costly monthly expense.

This is especially true for those of you who suffer from allergic rhinitis or hay fever. One of the biggest culprits for triggering symptoms related to these issues is pollen. Therefore, the less pollen that’s in the air around you, the less you’ll experience sneezing and coughing, suffering from a runny or stuffy nose, and dealing with itching, watering eyes.

The same thing is true for people who suffer from dust allergies. The best HEPA air purifier for allergies will suck in and collect the dust particles that float around inside your home. Once this dust is trapped, it can’t re-enter the room or get into your eyes, throat, or lungs.

Another positive side effect of using an air purifier is that you’ll be getting rid of other harmful particulates that you may not even know are causing your health and/or respiratory issues. This includes bacteria, viruses, mold, volatile organic compounds, etc.

As we mentioned at the beginning of this guide, an air purifier with a True HEPA filter is the best type of device you can get because it captures the smallest sized particles possible.

Using such a machine inside your home will create a clean air zone that’s free of both toxins and allergens. Most people start feeling a better overall sense of health after just a few days of use and can really notice a difference when they’re inside another person’s home or buildings where an air purifier is not present.

Hopefully, this information has been informative to you and has helped you understand how valuable an air purifier can be for your allergies. The best air purifier for allergies we recommended above are currently your top options when it comes to finding an air purifier that’s targeted for allergy relief.

Suffering from allergies doesn’t have to be an uphill battle. Fortunately, there’s now a way in which you can control them better while at home—using the best allergy air purifier you can find.

Common Symptoms of Allergies

Do you have allergic rhinitis (hay fever) or is it something else?

Below, are the most common symptoms of allergic rhinitis.

  • a runny, stuffy, or itchy nose
  • coughing
  • a sore or scratchy throat
  • itchy or watery eyes
  • frequent headaches

Once you come into contact with an allergen, you’ll immediately experience one or more of the above symptoms. However, some of those issues require long-term exposure to allergens such as excessive fatigue and headaches.

If you’re a person who experiences allergy symptoms all year round, then a dedicated allergy air purifier is a great device to have inside your home. Removing as many allergen particles as possible from indoor air can give you the much-needed relief you’re after.

Common Types of Indoor Allergens

The most common allergy triggers you’ll find in your home may surprise you.

Even though some of the allergens listed below may seem to be “outdoor” problems, many of these particles easily slip into your house and cause your allergy symptoms to flare.

That’s why having an air purifier is so important.

Air purifiers can remove these pollutants from your indoor air before they have a chance to trigger your allergic rhinitis.

  • tree pollen
  • flower pollen
  • grass pollen
